Cautions when Servicing

!• WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2 minutes (input voltage: 230 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then wait for at least 1 minute.

• Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual. Do not replace the outdoor board without checking.

I.1. Electrical work1-1. General cautions

OK NO

Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiringregulations, and guidance of each electric power company.Wiring for control (hereinafter referred to as transmission cable) shall be (50mm[1-5/8in.] or more) apart from power sourcewiring so that it is not influenced by electric noise from power source wiring. (Do not insert transmission cable and power source wire in the same conduit.)Be sure to provide designated grounding work to outdoor unit.Give some allowance to wiring for electrical part box of indoor and outdoor units, because the box is sometimes removedat the time of service work.Never connect 380~415V(220~240V) power source to terminal block of transmission cable. If connected,electrical partswill be damaged.Use 2-core shield cable for transmission cable. If transmission cables of different systems are wired with the samemultiple-core cable, the resultant poor transmitting and receiving will cause erroneous operations.

1. Use dedicated power supplies for the outdoor unit and indoor unit.

2. Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter. Make sure the power-supply voltage does not drop more

than 10%. Make sure that the voltage imbalance between the phases is 2% or less.

4. Specific wiring requirements should adhere to the wiring regulations of the region.5. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57). For example, use wiring such as YZW.

6. A switch with at least 3 mm contact separation in each pole shall be provided by the Air Conditioner installer.

Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly, heating or fire may result.

Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.

The breakers for current leakage should support Inverter circuit. (e.g. Mitsubishi Electric's NV-S series or equivalent). If no earth leakage breaker is installed, it may cause an electric shock.

Breakers for current leakage should combine using of switch.

Do not use anything other than a breaker with the correct capacity. Using a breaker of too large capacity may cause malfunction or fire.

If a large electric current flows due to malfunction or faulty wiring, earth-leakage breakers on the unit side and on the upstream side of the power supply system may both operate.Depending on the importance of the system, separate the power supply system or take protective coordination of breakers.

This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the above table at the interface point (power service box) of the user's supply.

The user must ensure that this device is connected only to a power supply system which fulfils the requirement above.If necessary, the user can ask the public power supply company for the system impedance at the interface point.

*If PAC-SC51KUA is used to supply power at TB7 side, no power supply need from Outdoor unit at TB7, Connector TB3 itself will therefore have 12. Not applicable to the PUMY model.*1 AE-200E/AE-50E has a built-in function to supply power to the M-NET transmission line. The amount of power that an AE-200E or an AE-50E can supply is equivalent to the power required by an MN converter (CMS-MNG-E) that is used for maintenance.

With the equivalent power consumption values in Table 2-3-1 and Table 2-3-2, PAC-SF46EPA can be designed into theair-conditioner system to ensure proper system communication according to 2-3-2-A.

2-3-2-A) If the total power consumption reaches 12, a PAC-SF46EPA should be set.

In order to ensure proper communication among Outdoor unit, Indoor unit, LOSSNAY, and OA processing unit GUF-RD(H), and Controllers, the transmission power situation for the M-NET should be observed. In some cases, Transmission booster should be used. Taking the power consumption of Indoor unit sized P15-P140 as 1, the equivalent power consumption or supply of others are listed at Table 2-3-1 and Table 2-3-2.

The power to System controller (excluding AE-200E, AE-50E, BAC-HD150, LM-AP) is supplied via M-NET transmission line. M-NET transmission line at TB7 side is called Centralized control transmission line while one at TB3 side is called Indoor-Outdoor transmission line. There are 2 ways to supply power to the System controller .A) Connecting to TB3 of the Outdoor unit and receiving power from the Outdoor unit.B) Connecting to TB7 of the Outdoor unit but receiving power from power supply unit PAC-SC51KUA. * System controllers (AE-200E, AE-50E, BAC-HD150, LM-AP) have a built-in function to supply power to the M-NET transmission lines, so no power needs to be supplied to the M-NET transmission lines from the outdoor units or from PAC-SC51KUA.

Maximum 3 System controllers can be connected to TB3. If there is more than 1 Outdoor unit, it is necessary to replace power supply switch connector CN41 with CN40 on one Outdoor unit.

2-3-3-B. When connecting to TB7 of the Outdoor unit but receiving power from PAC-SC51KUA.

2-3-3. Ensuring proper power supply to System controller

When using PAC-SC51KUA to supply transmission power, the power supply connector CN41 on the Outdoor units should be kept as it is. It is also a factory setting. 1 PAC-SC51KUA supports maximum 1 AG-150A unitdue to the limited power 24VDC at its TB3. However, 1 PAC-SC51KUA supplies transmission power at its TB2 equal to 5 Indoor units, which is referable at Table 2-3-2.If PZ-52SF-E, System controller, ON/OFF controller connected to TB7 consume transmission power more than 5 (Indoor units), Transmission booster PAC-SF46EPA is needed. PAC-SF46EPA supplies transmission power equal to 25 Indoor units.

■AG-150A*1 is recommended to connect to TB7 because it performs back-up to a number of data. In an air conditioner system has more than 1 Outdoor units, AG-150A receiving transmission power through TB7 on one of the Outdoor units would have a risk that the connected Outdoor unit failure would stop power supply to AG-150A, and disrupt the whole system. When applying apportioned electric power function, AG-150A is necessary to connected to TB7 and has its own power supply unit PAC-SC51KUA.*2

*1: AG-150A is an example model of system controllers.*2: Power supply unit PAC-SC51KUA is for AG-150A.

■How to connect system controllers (AE-200E, AE-50E, BAC-HD150, LM-AP) to a given systemSystem controllers (AE-200E, AE-50E, BAC-HD150, LM-AP) have a built-in function to supply

power to the M-NET transmission lines, so no power needs to be supplied to the M-NET

transmission lines from the outdoor units or from PAC-SC51KUA.

Leave the power supply connector on the outdoor unit connected to CN41 as it is. Refer to

2-3-2 for information about the power-supply capacity of each system controller

(AE-200E, AE-50E, BAC-HD150, LM-AP) to the low-level system controllers.

3-2-1. Use of the existing refrigerant piping

WARNINGBefore operating the compressor, make sure the refrigerant pipes are properly installed.

• Adequately insulate the liquid and gas refrigerant pipes to keep condensation from dripping.• Provide additional insulation on the refrigerant pipes as necessary to keep condensation from forming on the insulation surface. (Insulating material···Heat-resistance temperature: 120°C; Thickness: 15 mm or greater) * Installation of the unit in high-temperature high-humidity conditions, such as in the ceiling of the top floor, may require additional insulation.• Insulate refrigerant pipes with heat-resistant polyethylene foam and without leaving any gap between indoor unit and insulating material or between insulating materials. (Exposed pipes may cause condensation and pose burn hazard.)• Keep the piping length within the limits, and charge the required amount of refrigerant (R410A). * Before charging refrigerant, evacuate the extended piping and the indoor units, and charge refrigerant through the stop valve (applicable when the unit is

stopped). When charging refrigerant through the check valve on the suction side, use a safety charger to prevent liquid refrigerant from being inhaled (applicable when the unit is operated).

* When charging refrigerant, record the amount of refrigerant charged in the relevant section of the maintenance manual (attached to the product). • Determine the reusability of the existing piping, using the flowchart below.• If the diameter of the existing piping differs from the standard diameter, check the reusability of the piping and restrictive conditions for reuse.

• The following restrictions apply when using pipes with a diameter different from the standard recommended size.

• Main pipe size

Connecting non-standard diameter pipes

• Operating the compressor without the refrigerant pipes properly being connected and with the stop (ball) valve open, the compressor may suck in air, raising the pressure inside the refrigerant cycle abnormally high and resulting in pipe bursting and personal injury.

Cautionary notes on reusing the existing piping

Restrictions on extending piping/Amount of refrigerant to be charged (REPLACE units)When reusing the existing piping, calculate the amount of refrigerant to be charged using the formula below. The existing piping is usable if the result of the calculation below is less than 10 kg. If the calculation result is at or above 10 kg, use new piping. When reusing the existing piping, charge the amount of refrigerant required for the piping and for the indoor units.

Usability of pipes with non-standard diameters

Check the outer radial thickness of the existingpiping, and check the existing piping for damage.

The outer diameter and the radial thickness of the existingpiping meet the standards, and the piping is not damaged.

The outer diameter or the radial thickness of the existingpiping does not meet the standards, or the piping is damaged.

Operate the unit in the cooling for about 30 minutes, and perform a pumpdown operation.

Disconnect the existing air conditioners from the piping.

Connect new air conditioners.

Test run The existing piping cannot be reused. Install new piping.

Perform an air-tightness test, vacuum dry, (charge refrigerant), and check for refrigerant gas leak.

* Check the piping for corrosion, cracks, scratches, and deformation. Check the insulation materials and the supporting elements for obvious damage.

* If the existing air conditioners are inoperable, collectthe refrigerant using a refrigerant recovery device.

* The existing gas piping and petroleum heat-pumppiping cannot be reused. Install new piping.

<Additional Charge>Calculation of refrigerant charge

PUMY-P200

Included refrigerant amount when shipped from the factory

Additional refrigerant chargeRefrigerant for the extended piping is not included in the outdoor unit when the unit is shipped from the factory. Therefore, charge each refrigerant piping system with additional refrigerant at the installation site. In addition, in order to carry out service, enter the size and length of each liquid pipe and additional refrigerant charge amounts in the spaces provided on the “Refrigerant amount” plate on the outdoor unit.

Calculation of additional refrigerant charge▪ Calculate the additional charge using the liquid pipe size and length of the extended piping and total capacity of connected indoor units.▪ Calculate the additional refrigerant charge using the procedure shown to the right, and charge with the additional refrigerant.▪ For amounts less than 0.1 kg, round up the calculated additional refrigerant charge. (For example, if the calculated charge is 6.01 kg, round up the charge to 6.1 kg.)

4. Outdoor Installation SYSTEM DESIGN

4. Outdoor Installation4-1. Requirement on installation site

4-1-2. Installation at windy location.

4-1-1. General caution 4-1-3. FoundationA. Avoid locations exposed to direct sunlight or other sources

of heat.B. Select a location from which noise emitted by the unit will

not inconvenience the neighbors.C. Select a location permitting easy wiring and pipe access to

the power source and indoor unit.D. Avoid locations where combustible gases may leak, be

produced, flow, or accumulate.E. Note that water may drain from the unit during operation.F. Select a level location that can bear the weight and

vibration of the unit.G. Avoid locations where the unit can be covered by snow. In

areas where heavy snow fall is anticipated, special precautions such as raising the installation location or installing a hood on the air intake must be taken to prevent the snow from blocking the air intake or blowing directly against it. This can reduce the airflow and a malfunction may result.

H. Avoid locations exposed to oil, steam, or sulfuric gas.I. Use the transportation handles of the outdoor unit to

transport the unit. If the unit is carried from the bottom, hands or fingers may be pinched.

When installing the outdoor unit on a rooftop or other location unprotected from the wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.Strong wind entering the air outlet may impede the normal airflow and a malfunction may result.The following shows two examples of precautions against strong winds. Install an optional air guide if the unit is installed in a

location where strong winds from a typhoon, etc. may directly enter the air outlet. (Fig. 4-1-2a) Air guide

Position the unit so that the air outlet blows perpendicularly to the seasonal wind direction, if possible. (Fig. 4-1-2b) Wind direction

A. Be sure to install the unit in a sturdy, level surface to prevent rattling noises during operation. (see Fig. 4-1-3)

B. Foundation specifications are as follows. Thickness of concrete Weight-bearing capacity Foundation bolt Bolt length 120 [4-3/4"] 320 kg [706lbs] M10 [3/8"] 70 [2-25/32"]C. Make sure that the length of the foundation bolt is within 30

mm [1-3/16"] of the bottom surface of the base.D. Secure the base of the unit firmly with four-M10 [3/8"]

foundation bolts in sturdy locations.

Warning:A. The foundation base should be strong enough to support

the outdoor unit, otherwise, it may fall down and cause damage or injures.

B. The unit must be installed according to the instructions in order to minimize the risk of damage from earthquakes, typhoons, or strong winds.

5. Installation information5-1. General precautions5-1-1. Usage

The air-conditioning system described in this Data Book is designed for human comfort.This product is not designed for preservation of food, animals, plants, precision equipment, or art objects. To prevent quality loss, do not use the product for purposes other than what it is designed for.To reduce the risk of water leakage and electric shock, do not use the product for air-conditioning vehicles or vessels.

5-1-2. Installation environmentDo not install any unit other than the dedicated unit in a place where the voltage changes a lot, large amounts of mineral oil (e.g., cutting oil) are present, cooking oil may splash, or a large quantity of steam can be generated such as a kitchen.Do not install the unit in acidic or alkaline environment.Installation should not be performed in the locations exposed to chlorine or other corrosive gases. Avoid near a sewer.To reduce the risk of fire, do not install the unit in a place where flammable gas may be leaked or inflammable material is present.This air conditioning unit has a built-in microcomputer. Take the noise effects into consideration when deciding the in-stallation position. Especially in a place where antenna or electronic device are installed, it is recommended that the air conditioning unit be installed away from them.Install the unit on a solid foundation according to the local safety measures against typhoons, wind gusts, and earth-quakes to prevent the unit from being damaged, toppling over, and falling.

5-1-3. Backup systemIn a place where air conditioner's malfunctions may exert crucial influence, it is recommended to have two or more sys-tems of single outdoor units with multiple indoor units.

5-1-4. Unit characteristicsHeat pump efficiency depends on outdoor temperature. In the heating mode, performance drops as the outside air tem-perature drops. In cold climates, performance can be poor. Warm air would continue to be trapped near the ceiling and the floor level would continue to stay cold. In this case, heat pumps require a supplemental heating system or air circu-lator. Before purchasing them, consult your local distributor for selecting the unit and system.When the outdoor temperature is low and the humidity is high, the heat exchanger on the outdoor unit side tends to collect frost, which reduces its heating performance. To remove the frost, Auto-defrost function will be activated and the heating mode will temporarily stop for 3-10 minutes. Heating mode will automatically resume upon completion of defrost process.Air conditioner with a heat pump requires time to warm up the whole room after the heating operation begins, because the system circulates warm air in order to warm up the whole room.The sound levels were obtained in an anechoic room. The sound levels during actual operation are usually higher than the simulated values due to ambient noise and echoes. Refer to the section on "SOUND LEVELS" for the measurement location.Depending on the operation conditions, the unit generates noise caused by valve actuation, refrigerant flow, and pres-sure changes even when operating normally. Please consider to avoid location where quietness is required. For BC controller, it is recommended to unit to be installed in places such as ceilings of corridor, restrooms and plant rooms.The total capacity of the connected indoor units can be greater than the capacity of the outdoor unit. However, when the connected indoor units operate simultaneously, each unit's capacity may become smaller than the rated capacity. When the unit is started up for the first time within 12 hours after power on or after power failure, it performs initial startup operation (capacity control operation) to prevent damage to the compressor. The initial startup operation requires 90 minutes maximum to complete, depending on the operation load.

5-1-5. Relevant equipmentUse an earth leakage breaker (ELB) with medium sensitivity, and an activation speed of 0.1 second or less.Consult your local distributor or a qualified technician when installing an earth leakage breaker.If the unit is inverter type, select an earth leakage breaker for handling high harmonic waves and surges.Leakage current is generated not only through the air conditioning unit but also through the power wires. Therefore, the leakage current of the main power supply is greater than the total leakage current of each unit. Take into consideration the capacity of the earth leakage breaker or leakage alarm when installing one at the main power supply. To measure the leakage current simply on site, use a measurement tool equipped with a filter, and clamp all the four power wires together. The leakage current measured on the ground wire may not accurate because the leakage current from other systems may be included to the measurement value.Do not install a phase advancing capacitor on the unit connected to the same power system with an inverter type unit and its equipment.If a large current flows due to the product malfunctions or faulty wiring, both the earth leakage breaker on the product side and the upstream overcurrent breaker may trip almost at the same time. Separate the power system or coordinate all the breakers depending on the system's priority level.

5-1-6. Unit installationYour local distributor or a qualified technician must read the Installation Manual that is provided with each unit carefully before performing installation work.Consult your local distributor or a qualified technician when installing the unit. Improper installation by an unqualified person may result in water leakage, electric shock, or fire.Ensure there is enough space around each unit.

5-1-7. Optional accessories Only use accessories recommended by Mitsubishi Electric. Consult your local distributor or a qualified technician when installing them. Improper installation by an unqualified person may result in water leakage, electric leakage, system breakdown, or fire.Some optional accessories may not be compatible with the air conditioning unit to be used or may not suitable for the installation conditions. Check the compatibility when considering any accessories.Note that some optional accessories may affect the air conditioner's external form, appearance, weight, operating sound, and other characteristics.

5-1-8. Operation/MaintenanceRead the Instruction Book that is provided with each unit carefully prior to use.Maintenance or cleaning of each unit may be risky and require expertise. Read the Instruction Book to ensure safety. Consult your local distributor or a qualified technician when special expertise is required such as when the indoor unit needs to be cleaned.

5-2. Precautions for Indoor unit5-2-1. Operating environment

The refrigerant (R410A) used for air conditioner is non-toxic and nonflammable. However, if the refrigerant leaks, the oxygen level may drop to harmful levels. If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration from exceeding the safety limit even if the refrigerant should leak.If the units operate in the cooling mode at the humidity above 80%, condensation may collect and drip from the indoor units.

5-2-2. Unit characteristicsThe return air temperature display on the remote controller may differ from the ones on the other thermometers.The clock on the remote controller may be displayed with a time lag of approximately one minute every month.The temperature using a built-in temperature sensor on the remote controller may differ from the actual room tempera-ture due to the effect of the wall temperature.Use a built-in thermostat on the remote controller or a separately-sold thermostat when indoor units installed on or in the ceiling operate the automatic cooling/heating switchover.The room temperature may rise drastically due to Thermo OFF in the places where the air conditioning load is large such as computer rooms.Be sure to use a regular filter. If an irregular filter is installed, the unit may not operate properly, and the operation noise may increase.The room temperature may rise over the preset temperature in the environment where the heating air conditioning load is small.

5-2-3. Unit installationFor simultaneous cooling/heating operation type air conditioners (R2, WR2 series), the G-type BC controller cannot be connected to the 16HP outdoor unit model or above, and the G- and GA-type BC controllers cannot be connected to the 28HP model or above. The GB- and HB-type BC controllers (sub) cannot be connected to the outdoor unit directly, and be sure to use them with GA- and HA-type BC controllers (main).The insulation for low pressure pipe between the BC controller and outdoor unit shall be at least 20 mm thick. If the unit is installed on the top floor or in a high-temperature, high-humidity environment, thicker insulation may be necessary.Do not have any branching points on the downstream of the refrigerant pipe header.When a field-supplied external thermistor is installed or when a device for the demand control is used, abnormal stop of the unit or damage of the electromagnetic contactor may occur. Consult your local distributor for details.When indoor units operate a fresh air intake, install a filter in the duct (field-supplied) to remove the dust from the air.The 4-way or 2-way Airflow Ceiling Cassette Type units that have an outside air inlet can be connected to the duct, but need a booster fan to be installed at site. Refer to the chapter "Indoor Unit" for the available range for fresh air intake volume. Operating fresh air intake on the indoor unit may increase the sound pressure level.

5-3. Precautions for Fresh air intake type indoor unit5-3-1. Usage

This unit mainly handles the outside air load, and is not designed to maintain the room temperature. Install other air con-ditioners for handling the air conditioning load in the room.

5-3-2. Unit characteristicsThis unit cannot perform the drying operation. The unit will continue the fan operation and blow fresh air (air that is not air-conditioned) when the Heating Thermo-OFF or Cooling Thermo-OFF mode is selected.The fan may stop tentatively when the unit is connected to the simultaneous cooling/heating operation type outdoor unit (R2, WR2 series) or during the defrost cycle.This unit switches the Thermo ON or OFF depending on the room temperature. The outside air is directly supplied into the room during Thermo OFF. Take caution of the cold supply air due to low outside air temperature and of condensation in the room due to high humidity of the outside air.Outside air temperature ranges for the operation must be as follows:Cooling: 21ºCD.B./15.5ºCW.B. ~ 43ºCD.B./35ºCW.B.Heating: -10ºCD.B.~ 20ºCD.BThe unit is forced to operate Thermo OFF (fan operation) when the outside air temperature is as follows.Cooling: 21ºCD.B or below; Heating: 20ºCD.B or aboveEither a remote controller (sold separately) or a remote sensor (sold separately) must be installed to monitor the room temperature.If only this unit is used as an indoor unit, condensation may form at the supply air grill while the unit is operated in the cooling mode. This unit cannot operate dehumidifying.Use the unit in the way that the airflow rate will not exceed the 110% of the rated airflow.

5-4. Precautions for Outdoor unit/Heat source unit5-4-1. Installation environment

Outdoor unit with salt-resistant specification is recommended to use in a place where it is subject to salt air.Even when the unit with salt-resistant specification is used, it is not completely protected against corrosion. Be sure to follow the directions or precautions described in Instructions Book and Installation Manual for installation and mainte-nance. The salt-resistant specification is referred to the guidelines published by JRAIA (JRA9002).Install the unit in a place where the flow of discharge air is not obstructed. If not, the short-cycling of discharge air may occur.Provide proper drainage around the unit base, because the condensation may collect and drip from the outdoor units. Provide water-proof protection to the floor when installing the units on the rooftop.In a region where snowfall is expected, install the unit so that the outlet faces away from the direction of the wind, and install a snow guard to protect the unit from snow. Install the unit on a base approximately 50 cm higher than the expect-ed snowfall. Close the openings for pipes and wiring, because the ingress of water and small animals may cause equip-ment damage. If SUS snow guard is used, refer to the Installation Manual that comes with the snow guard and take caution for the installation to avoid the risk of corrosion.When the unit is expected to operate continuously for a long period of time at outside air temperatures of below 0ºC, take appropriate measures, such as the use of a unit base heater, to prevent icing on the unit base. (Not applicable to the PUMY series)Install the snow guard so that the outlet/inlet faces away from the direction of the wind.When the snow accumulates approximately 50 cm or more on the snow guard, remove the snow from the guard. Install a roof that is strong enough to withstand snow loads in a place where snow accumulates.Provide proper protection around the outdoor units in places such as schools to avoid the risk of injury.A cooling tower and heat source water circuit should be a closed circuit that water is not exposed to the atmosphere. When a tank is installed to ensure that the circuit has enough water, minimize the contact with outside air so that the oxygen from being dissolved in the water should be 1 mg/L or less.Install a strainer (50 mesh or more recommended) on the water pipe inlet on the heat source unit.Interlock the heat source unit and water circuit pump.Note the followings to prevent the freeze bursting of pipe when the heat source unit is installed in a place where the ambient temperature can be 0ºC or below. Keep the water circulating to prevent it from freezing when the ambient temperature is 0ºC or below. Before a long period of non use, be sure to purge the water out of the unit.Salt-resistant unit is resistant to salt corrosion, but not salt-proof. Please note the following when installing and maintaining outdoor units in marine atmosphere.1. Install the salt-resistant unit out of direct exposure to sea breeze, and minimize the exposure to salt water mist.2. Avoid installing a sun shade over the outdoor unit, so that rain will wash away salt deposits off the unit.3. Install the unit horizontally to ensure proper water drainage from the base of the unit. Accumulation of water in the base

of the outdoor unit will significantly accelerate corrosion.4. Periodically wash salt deposits off the unit, especially when the unit is installed in a coastal area.5. Repair all noticeable scratches after installation and during maintenance.6. Periodically check the unit, and apply anti-rust agent and replace corroded parts as necessary.

5-4-2. Circulating waterFollow the guidelines published by JRAIA (JRA-GL02-1994) to check the water quality of the water in the heat source unit regularly.A cooling tower and heat source water circuit should be a closed circuit that water is not exposed to the atmosphere. When a tank is installed to ensure that the circuit has enough water, minimize the contact with outside air so that the oxygen from being dissolved in the water should be 1 mg/L or less.

5-4-3. Unit characteristicsWhen the Thermo ON and OFF is frequently repeated on the indoor unit, the operation status of outdoor units may be-come unstable.

5-4-4. Relevant equipmentProvide grounding in accordance with the local regulations.

5-5. Precautions for Control-related items5-5-1. Product specification

To introduce the MELANS system, a consultation with us is required in advance. Especially to introduce the electricity charge apportioning function or energy-save function, further detailed consultation is required. Consult your local distributor for details.Billing calculation for AE-200E/AE-50E, AG-150A, GB-50ADA, TG-2000A, or the billing calculation unit is unique and based on our original method. (Backup operation is included.) It is not based on the metering method, and do not use it for official business purposes. It is not the method that the amount of electric power consumption (input) by air conditioner is calculated. Note that the electric power consumption by air conditioner is apportioned by using the ratio corresponding to the operation status (output) for each air conditioner (indoor unit) in this method.In the apportioned billing function for AE-200E/AE-50E, AG-150A and GB-50ADA, use separate watthour meters for A-control units, K-control units, and packaged air conditioner for City Multi air conditioners. It is recommended to use an individual watthour meter for the large-capacity indoor unit (with two or more addresses).When using the peak cut function on the AE-200E/AE-50E, AG-150A or GB-50ADA, note that the control is performed once every minute and it takes time to obtain the effect of the control. Take appropriate measures such as lowering the criterion value. Power consumption may exceed the limits if AE-200E/AE-50E, AG-150A or GB-50ADA malfunctions or stops. Provide a back-up remedy as necessary.The controllers cannot operate while the indoor unit is OFF. (No error) Turn ON the power to the indoor unit when operating the controllers.When using the interlocked control function on the AE-200E/AE-50E, AG-150A, GB-50ADA, PAC-YG66DCA, or PAC-YG63MCA, do not use it for the control for the fire prevention or security. (This function should never be used in the way that would put people's lives at risk.) Provide any methods or circuit that allow ON/OFF operation using an external switch in case of failure.

5-5-2. Installation environmentThe surge protection for the transmission line may be required in areas where lightning strikes frequently occur.A receiver for a wireless remote controller may not work properly due to the effect of general lighting. Leave a space of at least 1 m between the general lighting and receiver.When the Auto-elevating panel is used and the operation is made by using a wired remote controller, install the wired remote controller to the place where all air conditioners controlled (at least the bottom part of them) can be seen from the wired remote controller. If not, the descending panel may cause damage or injury, and be sure to use a wireless remote controller designed for use with elevating panel (sold separately).Install the wired remote controller (switch box) to the place where the following conditions are met. Where installation surface is flatWhere the remote controller can detect an accurate room temperatureThe temperature sensors that detect a room temperature are installed both on the remote controller and indoor unit. When a room temperature is detected using the sensor on the remote controller, the main remote controller is used to detect a room temperature. In this case, follow the instructions below. Install the controller in a place where it is not subject to the heat source. (If the remote controller faces direct sunlight or supply air flow direction, the remote controller cannot detect an accurate room temperature.) Install the controller in a place where an average room temperature can be detected. Install the controller in a place where no other wires are present around the temperature sensor. (If other wires are present, the remote controller cannot detect an accurate room temperature.) To prevent unauthorized access, always use a security device such as a VPN router when connecting AE-200E/AE-50E, AG-150A, GB-50ADA, or TG-2000A to the Internet.

6. Caution for refrigerant leakage SYSTEM DESIGN

6. Caution for refrigerant leakageThe installer and/or air conditioning system specialist shall secure safety against refrigerant leakage according to local regulations or standards.The following standard may be applicable if no local regulation or standard is available.

6-1. Refrigerant property

6-2. Confirm the Critical concentration and take countermeasure

R410A refrigerant is harmless and incombustible. The R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation. Therefore, the Critial concentration specified below shall not be exceeded even if the leakagehappens.

Critical concentrationCritical concentration hereby is the refrigerant concentration in which no human body would be hurt if immediate measures can be takenwhen refrigerant leakage happens.

Critical concentration of R410A: 0.44kg/m3

(The weight of refrigeration gas per 1 m3 air conditioning space.);The Critical concentration is subject to ISO5149, EN378-1.

For the CITY MULTI system, the concentration of refrigerant leaked should not have a chance to exceed the Critical concentration in any situntion.

The maximum refrigerant leakage concentration (Rmax) is defined as the result of the possible maximum refrigerant weight (Wmax)leaked into a room divided by its room capacity (V). It is referable to Fig.6-1. The refrigerant of Outdoor unit here includes its originalcharge and additional charge at the site.The additional charge is calculated according to “3-3. Refrigerant charging calculation” and shall not be over charged at the site.Procedure 6-2-1~3 tells how to confirm maximum refrigerant leakage concentration (Rmax) and how to take countermeasures againsta possible leakage.

If a room having total opening area more than 0.15% of the floor area at a low position with another room/space, the two rooms/space areconsidered as one. The total space shall be added up.

6-2-2.Find the possible maximum leakage (Wmax) in the room. If a room has Indoor unit(s) from more than 1 Outdoor unit, add up the refriger-ant of the Outdoor units.

6-2-3.Divide (Wmax) by (V) to get the maximum refrigerant leakage concentration (Rmax).6-2-4.Find if there is any room in which the maximum refrigerant leakage concentration (Rmax) is over 0.44kg/m3.

If no, then the CITY MULTI is safe against refrigerant leakage.If yes, following countermeasure is recommended to do at site.Countermeasure 1: Let-out (making V bigger)

Design an opening of more than 0.15% of the floor area at a low position of the wall to let out the refrigerant whenever leaked.e.g.make the upper and lower seams of door big enough.

Countermeasure 2: Smaller total charge (making Wmax smaller) e.g.Avoid connecting more than 1 Outdoor unit to one room.e.g.Using smaller model size but more Outdoor units.e.g.Shorten the refrigerant piping as much as possible.

Countermeasure 3: Fresh air in from the ceiling (Ventilation) As the density of the refrigerant is bigger than that of the air.Fresh air supply from the ceiling is better than air exhausting from the ceiling.Fresh air supply solution refers to Fig.6-2~4.
