The service rules of the R407C product The service rules of the R410A product

1. The service rules of the new refrigerant R407C product COOLWEX uses the green refrigerant R407C firstly in China. Its thermal characters are similar to R22, but there is little difference between them.

1.1 The main difference between R407C and R22:

1.2 Service precautions: 1.2.1 Because R407C is a mixture composed of three kinds of matter, when vapor phase and liquid

phase coexist, the component of the vapor phase is different from the liquid phase. When we fill the refrigerant, we must ensure to fill it in liquid phase, in order to maintain the stability of the character.

1.2.2 The leakage of the refrigerant is from vapor side or liquid side, and the leakage from vapor side could make the component change and impact the character seriously. So when the amount of the leakage is up to 5%, we need discharge all refrigerant in the system, and fill liquid refrigerant according to amount in nameplate.

1.2.3 Because the lubricant fit for refrigerant R407C is ester refrigerating engine oil (POE) or ether refrigerating engine oil (PVE). The mineral lubricant fit for refrigerant CFC and HCFC is weak in consistent with the HFC, and it doesn’t fit for the refrigerant HFC. So when the compressor using new refrigerant R407C is worn out, to replace it by compressor of CFC or HCFC is forbidden.

1.2.4 When the connection of the refrigerant pipe is finished, before the system start up we should vacuum the indoor unit by cut-off valve or discharge the indoor unit air by refrigerant R407C bottle. Discharged the air in system by outdoor unit refrigerant is forbidden.

1.2.5 Ester oil could adsorb the water in the air. In order to removemoisture in refrigeration system, avoid capillary jammed by ice and the ester lubricant oil decomposed with water, we use desiccant in system. Artificial zeolite (molecular sieve R etc.) is the effective water sorbent. Toavoid absorb refrigerant but only absorbmoisture, we use the molecular sieve whose aperture is smaller than the molecule of the refrigerant. For R407C we should adopt XH-11 rather than XH-9AK and 4A-NRG.

1.2.6 Because the corrosion of R407C and POE to high molecular material is different from R22 and mineral oil, the airproof material inside high/low pressure valve and foul-way valve needs to be changed in refrigeration system, such as R407C, polyurethane rubber etc. The high/low pressure valve and four-way valve which are fit for R22 couldn’t be used in service.

1.2.7 When there is leakage, filling with other kind of refrigerant is forbidden. 1.2.8 When we need to vacuum the system, we should use the special quick joint, but use the quick

joint of other refrigerant is forbidden lest pollute by mixing refrigerant. The time for vacuuming is

R407C R22 Component HFC32/125/134a HCFC22 The ratio of mix Wt％ 23/25/52 100 The saturation liquid density Kg/m3 1136 1191

about 30 minutes, and vacuity is less than 133Pa. 1.3 Precautions: 1.3.1 Regulations Being liquefied vapor, R-407C and R-410A are high-pressure vapor, the high-pressure gas regulation is applicable. Before use it, please refer to high-pressure gas regulation. To prevent the high-pressure vapor from causing damage, the regulation should be followed. 1.3.2 Usage of vessel

Being high-pressure vapor, R-407C and R-410A are contained in high-pressure vessel. The safety condition of vessel is good, but if you don’t use it carefully, you may damage the vessel and cause accident.

1.3.3 Storage Although R-407C and R-410A are nonflammable, when they are stored with the normal high-pressure gas, we should place them in the good ventilation area. In addition, there are safe devices in the high-pressure vessel. Please note that when the temperature (fusible valve) or pressure (spring safe valve) is up to a certain value, it will eject vapor.

1.3.4 Ventilation Because R-407C and R-410A are heavier then air, they will go down. If room is full of the leakage vapor, the density of oxygen will decrease, and cause people suffocated. In addition, if you light the fire when there is R-407C in the air, it will produce the toxic gas with pungent odor and corrosiveness.

1.3.5 Precautions about health For R-407C, R-410A and normal liquefied high-pressure vapor, please don’t contact with skin directly, and prevent being splashed into eyes and avoid drinking.

1.3.6 The following are the urgent disposal methods: Splash into eyes: Wash eyes with pure water for more than 15 minutes, and don’t knead the eyes or blink. Please wash eyes with watery boric acid water if the ache gets heavy. To avoid the accident, please ensure that you wear the protection glasses. Contact with skin directly The temperature will decrease rapidly by evaporation if R-407C and R-410A expose to air in liquid phase. So if the liquid contacts with skin directly, it may cause frostbite. If there are freeze burns, please go to see the doctor immediately.

2. The service rules of the R410A product 2.1 There are some differences between air conditioner of R410A s and that of R22: 2.1.1 The compressor used is different, it is a new refrigerant compressor (special); 2.1.2 The air conditioner of new refrigerant R410A has a drier, while the A/C of R22 doesn’t have. 2.1.3 There is no difference between the evaporator, condenser and system pipe of new refrigerant

R410A A/C and that of R22 A/C in appearance. The requirement of new refrigerant R410A A/C for craft is higher, and the amount of moisture and impurity in the system is less than that of A/C using R22. The resistance to pressure is higher.

2.1.4 The manufacture process is different, the requirement of air conditioner using R410A for craft is high.

2.2 Refrigerant system: 2.2.1 The high pressure of refrigerant system is 3.0 Mpa, and the low pressure is 1.2 Mpa. (The

value is 1.5 times more than that of R22 under the same condition) 2.2.2 When installing the split type of new refrigerant R410A, all connecting pipes must be special

pipes of R410A. Discharging air must use refrigerant R410A, and couldn’t misuse the connecting pipe and refrigerant of A/C using R22. Otherwise, it will destroy the stability of A/C.

2.2.3 Because the compressor of refrigerant R410A split type uses POE oil, which can react with moisture to form water and acid. The water produced by reaction could react further, and if the

7

chain reaction proceeds continually, the water in the system will be more and more. It will cause the capillary ice blocking; at the same time, acidity of working substance circulated in the system will be higher and higher (the value of PH is lower and lower), and it may corrode the components and parts in the system. The phenomenon of copperizing would happen. When installing A/C, the action should be prompt, and after opening the plug of connecting pipe we must tighten the nut in 5 minutes. The time of discharging air should be enough. When installing A/C, the sweat drops into the connecting pipe is forbidden; the infusible impurity mixed in the system is forbidden. It is better to install the A/C of refrigerant R410A split type in fine weather, do not do it in rainy day, nor humid weather.

2.2.4 The chlorine ion could react with POE oil to form acid, and the acid corrodes the components and parts of refrigerant system. So pollute the system with chlorine ion in installation is forbidden, such as sweat beads and other impurities that contain chlorine ion.

2.2.5 Whatever the reason we must change the drier, if the refrigerant system is exscinded in service, after we exscind the refrigerant system, we must use something to wrap the fracture lest the moisture in air enters into the system. The time that refrigerant system expose to air should be less than 5 minutes.

2.2.6 Must weld the drier into system in 5 minutes in order to isolate the air when changing it. Otherwise it will influence the performance of the drier.

2.2.7 Must use special pump after service. The lubricant should be the grease. The pump couldn’t be used to vacuum the A/C of refrigerant R22, otherwise it would cause the contamination of refrigerant, and influence the performance of A/C. The time of vacuuming must be over 25 minutes, Otherwise the moisture in system will be too high, and affect the stability of A/C.

2.2.8 If need to change the components and parts, must use the special one of R410A in service. Using the components and parts of R22 is forbidden; otherwise it would affect the stability of A/C. The refrigerant R410A should be placed in environment under 30. If the refrigerant has been

placed in environment above 30, it is necessary to store the refrigerant in the environment below 30 for more than 24 hours. Otherwise the component of refrigerant would be changed and it affects the performance of A/C.

8.7.3 Low room temperature protection:

When room temperature decreases to below 10, compressor and outdoor fan will stop(indoor fan is Breeze). Dehumidifying operation will be resumed when room temperature restores to over 13.

8.7.4 At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same as that of cooling mode.

8.8 Heating mode 8.8.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 4-way valve

must delay 2 minutes compared with compressor if the compressor changed into non-heating mode or turned off. 4-way valve doesn't delay in dehumidifying mode.

8.8.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost.

8.8.3 Action of compressor and outdoor fan motor at heating mode: compressor must run for 7 minutes after starting and then judge temperature. Meanwhile other protections are still valid.

8.9 Defrosting operation (Available for heating only). 8.9.1 Defrosting condition: Defrosting starts when either of the following ①&②:

① A and B are satisfied: A: The compressor keeps running for 40 minutes or more. B: The temperature difference of evaporator and room temperature meets one of the following:

Temp. of evaporator---room temp.

Fan speed is high ≤THDEFROST

Fan speed is mid ≤TMDEFROST

Fan speed is low ≤TLDEFROST

Breeze Meet only if it is Breeze

② Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan

with the compressor still running. Add up to 90 minutes. 8.9.2 Defrosting time

If the temp. difference condition ① is satisfied for less than 40 minutes, this can be regarded as severe frosting. The defrosting time is 10 minutes. If the temp. difference condition ② is satisfied for more than 40 minutes, the defrosting time is 6 minutes. If the temp. difference condition ① is satisfied out of 40 minutes, generally the defrosting time is 6 minutes, after three continuous 6-minute defrost, the fourth should be 10 minutes defrost. The circulation is as following:

→6-minute defrost → 6-minute defrost→6-minute defrost→10-minute defrost→

8.9.3 Ending condition of defrosting If one of following conditions is satisfied, end the defrost and turn into heating mode: A. The defrost time has reached to 6 or 10 minutes. B. The compressor current has reached to IDEFROST or above, IDEROST differs in different models.

92

8.9.4 Defrosting Actions:

8.9.7 Turn into heating mode, turn off the heating mode in 7 minutes. 8.10 Automatic operation mode 8.10.1 The air conditioner automatically selects one of the following operation modes: cooling, heating or

fan only according to the temp. difference between room temp. (TA) and set temp. (TS). TA—TS Operation mode

TA—TS>2 Cooling

-1≤TA—TS≤+2 Fan-only

TA—TS<-1 Heating (air-only for cooling only type)

8.10.2 The indoor fan blows automatically in corresponding selected mode. 8.10.3 The motion of indoor fan’s blade should accord with the selected operation mode.

8.11 Forced cooling function 8.11.1 Select forced cooling function with the forced cooling button or the switch. 8.11.2 The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan mode is

set as low, the A/C operates at the DRY mode with a set temp. of 24. 8.11.3 All protections of remote control cooling are available at forced cooling operation. 8.12 Forced Auto function

Select forced auto function with the forced auto button or the switch. In forced auto status the A/C operates at remote control mode with a set temp. of 24.

8.13 Timer Function 8.14 Economic Running 8.14.1 The economic running function is available at cooling, heating or auto mode. 8.14.2 Cooling:

The set temperature rise 1 per hour. Two hours later, the set temperature will maintain as a constant and the fan speed is kept at low speed.

8. Electric Control Functions

8.1 Control system The control system adopts modular design, that is, all indoor units communicate with outdoor units, ref. to the following figures for the control structure between indoor units and outdoor units. In the structure, the indoor control board receives the information from users (for exam. set temp., fan speed etc.) and environment (ex, indoor coil temp., indoor temp. etc.) ,and organize it to control the action of relevant parts, then transmits the signals to outdoor control board through the following communication circuit. Outdoor control board can deal with the information from indoor unit and figure out the best running mode, then transfer the instruction to indoor units to carry out it. Indoor unit receive the user’s remote control signals. Indoor unit Outdoor unit T2B T1、T2、Ts T3、 T4、T3 Fan Speed Pressure switch Pressure switch

3、 T2B Indoor evaporator outlet temp. 4、 Ts Indoor setting temp. 5、 T3 Outdoor heat-exchanger outlet temp. 6、 T4 Outdoor ambient temp. 8.2 Protection function 8.2.1 AC Volt Protection a. Over-voltage protection

When AC voltage ≤ 260V for 30 seconds, Outdoor Unit resumes operation. When AC voltage ≥ 270V for 30 seconds, Outdoor Unit stops operation and alarms.

Note: Voltage sampling precision is ±3%. b. Lack-voltage protection Volt increase (Resume)

198

190 MAX=78Hz 190 180 172 MAX=70Hz 172 167 Stop

Volt decrease (Limited Frequency) 8.2.2 AC Amp Protection The outdoor control board checks the compressor current and do over-current protection. If the compressor current is over the scheduled value, the system will stop and all indoor units will display malfunction code. Note: 1. In order to prevent protection due to too big LRA when compressor starts, the outdoor control board begins to check the compressor current after 10 seconds. 2. If current protection happens, the compressor will stop and restart 3 minutes later. 8.2.3 High-pressure Protection and Low-pressure Protection

Volt(V)

212

The High-pressure switch and Low-pressure switch are installed at suction pipe and discharge pipe separately. And users can select to install. Normally, the high-pressure switch is cut down when higher than 425Psi (3.3Mpa Cut down, 2.4Mpa Resume). While the low-pressure switch is cut down when lower than 7Psi (0.05Mpa On, 0.15Mpa Resume). Under high-pressure protection or low-pressure protection, the compressor will stop and restart 3 minutes later. 8.2.4 Outdoor Unit communication protection 8.2.4.1 Communication protection between indoor unit and outdoor system chip If the outdoor unit can’t receive the indoor signal for 30 seconds, then the indoor units are judged as no starting and there is no alarm signal. If the indoor units send signal to system chip for 2 minutes and no feedback signal is received, then judge as communication malfunction. 8.2.4.2 Communication protection between outdoor system chip and inverter chip If can’t receive signal or receive wrong signal for over 2 minutes, Indoor/Outdoor Unit stops operation. When the signal is right, Indoor/Outdoor Unit restarts. 8.2.5 Outdoor condenser high temperature protection Under cooling mode, if T3〉65 for 3 minutes, the compressor will stop. When T3〈52, the protection is not valid. When protection is released, the compressor restarts 3 minutes later. 8.2.6 Temperature Sensor short/open protection When the outdoor condenser pipe temperature T3, outdoor ambient temperature T4, indoor evaporator outlet temperature T2B are checked out of range 0.05～4.95V, it think temperature sensor short/open protection. The compressor, four-way valve and outdoor fan motor will stop and send malfunction signal to indoor units. When the volt is resumed to the range 0.05～4.95V, then resume signal to indoor units and control on-off of the compressor, four-way valve and outdoor fan motor by indoor size. 8.2.7 Outdoor low temperature protection If the outdoor temperature is lower than -15 for 1hour, the compressor and fan motor will stop. And any operation is not valid. If the outdoor temperature is higher than -12 for 10 minutes and the compressor stops operation for 1h, or the outdoor temperature is higher than 5 for 10 minutes, then restart and enter into the prior operation mode. If any indoor unit sends out this protection request, the outdoor unit will stop compressor until all indoor units have not this protection request. 8.2.8 Compressor pre-heating function When the outdoor temperature is lower than 3 and the compressor stops operation for more than 3 hours, or the outdoor temperature is lower than 3 and the power is just put on, the compressor enters into pre-heating condition. 8.3 Display function

8.7.3 Low room temperature protection:


8.7.4 At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same as that of cooling mode.

8.7.5 At dehumidifying mode, the action of fans of indoor is the same as that of air-only mode. 8.8 Heating mode 8.8.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 4-way valve

must delay 2 minutes compared with compressor if the compressor changed into non-heating mode or turned off. 4-way valve doesn't delay in dehumidifying mode.

8.8.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost.

8.8.3 Action of compressor and outdoor fan motor at heating mode: compressor must run for 7 minutes after starting and then judge temperature. Meanwhile other protections are still valid.

8.8.7. The louver opens to Standard Angle ANGLHEAT when power is on for the first time 8.9 Defrosting operation (Available for heating only). 8.9.1 Defrosting condition: Defrosting starts when either of the following ①&②:

① A and B are satisfied: A: The compressor keeps running for 40 minutes or more. B: The temperature difference of evaporator and room temperature meets one of the following:

Temp. of evaporator---room temp.

Fan speed is high ≤THDEFROST

Fan speed is mid ≤TMDEFROST

Fan speed is low ≤TLDEFROST

Breeze Meet only if it is Breeze

② Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan

with the compressor still running. Add up to 90 minutes. 8.9.2 Defrosting time

If the temp. difference condition ① is satisfied for less than 40 minutes, this can be regarded as severe frosting. The defrosting time is 10 minutes. If the temp. difference condition ② is satisfied for more than 40 minutes, the defrosting time is 6 minutes. If the temp. difference condition ① is satisfied out of 40 minutes, generally the defrosting time is 6 minutes, after three continuous 6-minute defrost, the fourth should be 10 minutes defrost. The circulation is as following:

→7.5-minute defrost → 7.5-minute defrost→7.5-minute defrost→10-minute defrost→

8.9.3 Ending condition of defrosting If one of following conditions is satisfied, end the defrost and turn into heating mode: A. The defrost time has reached to 7.5 or 10 minutes. B. The compressor current has reached to IDEFROST or above, IDEROST differs in different models.

8.9.4 Defrosting Actions:

8.10 Automatic operation mode 8.10.1 The air conditioner automatically selects one of the following operation modes: cooling, heating or

fan only according to the temp. difference between room temp. (TA) and set temp. (TS). TA—TS Operation mode

TA—TS>2 Cooling

-1 ≤TA -TS≤+2 Fan-only

TA-TS<-1 Heating (air-only for cooling only type)

8.10.2 The indoor fan blows automatically in corresponding selected mode. 8.10.3 The motion of indoor fan’s blade should accord with the selected operation mode. 8.10.4 One mode should be carried out for at least 15 minutes once selected. If the compressor cannot

start for 15 minutes, reselect the operation mode according to the room temp. and set temp., or reselect when the set temp. varies.

8.11 Forced cooling function 8.11.1 Select forced cooling function with the forced cooling button or the switch. 8.11.2 The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan mode is

set as low, the A/C operates at the DRY mode with a set temp. of 24. 8.11.3 All protections of remote control cooling are available at forced cooling operation. 8.12 Forced Auto function

Select forced auto function with the forced auto button or the switch. In forced auto status the A/C operates at remote control mode with a set temp. of 24.

8.13 Timer Function 8.14 Economic Running 8.14.1 The economic running function is available at cooling, heating or auto mode. 8.14.2 Cooling:

The set temperature rise 1 per hour. Two hours later, the set temperature will maintain as a

constant and the fan speed is kept at low speed. 8.14.3 Heating:

The set temperature decrease 1 per hour. Two hours later, the set temperature will maintain as a constant and the air circulation is kept at low speed (Cold air proof function takes precedence over all).

8.14.4 Auto: The economic running function operates in accordance with selected running mode by auto mode.

8.15 Auto restart function In case of a sudden power failure, this function automatically sets the unit to previous settings before the power failure when power returns.
