01. PIPE RUN PLANNING
Planning of pipe runs should take into account the following criteria:
NOTE: Non-compliant pipe work will void the warranty.
02. NITROGEN PURGING
All brazing to be done with OFN (oxygen-free nitrogen) purging through the pipe work system.
Nitrogen should be circulated into the pipe work branches and are to be welded using a flow regulator. This prevents oxidation
of the inside of the pipe surface. This oxidation can block filters and LEV valve orifices, and cause oil contamination and
compressor failure.
ALL BRAZING MUST BE CARRIED OUT USING DRY NITROGEN PURGING.
NOTE: Failure to follow this guideline will void the warranty.

----
PIPE:
All pipe used in R410A installations is to comply with
AS/NZ Standard 1677 Part 2. Copper tube of the correct
wall thickness must be used.
SEALED PIPE: Hard and soft drawn copper tube stored on site prior to
installation must have plastic end caps fitted to prevent
ingress of moisture and foreign objects. Bends and fittings
should be kept dry and in the original packing prior to
installation.
PENETRATIONS: All building penetrations should be made in such a way that
the bare copper pipe does not contact the building fabric.
BENDS:Minimise the number of bends. Ensure all soft drawn bends
are made with the correct size benders and are of full internal
diameter.
PIPE CLAMPS: Ensure that the pipe work is fixed so there is no tension on
the indoor or outdoor unit connections. This can lead to stress
fractures at the flare/flange.
PIPE RUN LENGTHS: Ensure the maximum pipe run lengths comply with system
specifications.
03. FLARE / FLANGE JOINTING PROCEDURE
R410A operates at much higher pressures than R22 and R407C refrigerants.
For this reason copper flare connection dimensions must meet the following criteria:
5
R410A flare nuts must also be used. Failure to do so can cause joint failure and refrigerant loss.
Prior to connecting flange and flare connections oil should be applied to the mating faces. Failure to do this causes tearing of
the copper flare surface. This causes leaking joints and joint failure due to material stress. The use of oil on connections also
allows the correct torque to be applied to the flare nut without pipe damage occurring.
Alkyl benzene oil is to be used to lubricate the connections. Alkyl benzene oil is hygroscopic (absorbs moisture) and should be
kept in an air tight container. The use of mineral based oil is not permitted as it contaminates the oil system and causes sludge
to form.
04. DAILY SECTIONAL SYSTEM PRESSURING
During installation of multiple circuit systems, it is recommended that at the end of each day, the pipe work be left pressurised
and any pressure loss be investigated prior to commencement of further piping the next day.
This procedure performs two functions:
1. Isolates any leaks to a small section of piping making it easier to trace and repair.
2. Pressurised pipe work prevents moisture and other foreign objects from entering the pipe work.
It is easier to pressurise the indoor units from the BC connection boxes.
NOTE: Please ensure that both vapour and liquid connections are pressurised (looped) otherwise damage to indoor LEVs can occur.
Risers can be capped prior to the BC boxes and pressurised from the outdoor unit service valve connections.
Pressure for overnight testing to 100 psi using dry nitrogen.
A final system pressure test of 500 psi using dry nitrogen held for 24 hours is required to prove complete system tightness prior
to evacuation. The results must be noted.
05. EFFECTIVE EVACUATION TECHNIQUES
• Effective evacuation technique at time of installation is a primary contributor to the long and trouble-free operation of a refrigerant system. The downstream effects of moisture in a system can vary and include valve blockages, high head pressures, oil sludging to copper plating of compressor internal parts and eventual compressor failures.
• Triple Evacuation Method must be used when evacuating the system prior to commissioning. The vacuum values reached at each stage of evacuation must be noted on the pre-commissioning sheet contained in this booklet.
• Both the initial and second evacuation must be carried out with the schraedar valve cores removed. This allows the vacuum pump to work more effectively at removing any moisture, and allows the dry nitrogen purges to be released quicker. Core removal tools and vacuum charge valves are available, and allow the cores to be removed on the final evacuation.
• A check valve must be fitted to the vacuum pump to prevent the vacuum pump oil being sucked into the City Multi system if the power is removed from the vacuum pump.
NOTE: Most vacuum pump oil is mineral-based and this is incompatible with the synthetic-based oil in the City Multi system.

• A two-stage vacuum pump with fresh vacuum pump oil capable of a vacuum of 50 microns should be selected. Where possible it is best engineering practice to have a pump specifically for installations rather than the service pumps which tend to deteriorate during service tasks.
• Using a 3/8” connection line to the manifold is important to allow quicker vapour volume removal.
• An accurate vacuum gauge is an essential tool to gauge the system tightness and the effectiveness of the evacuation procedure. A vacuum of 1000 microns should be reached on the initial vacuum test. A rapid rise indicates a leak is present. A small, slow rise indicates the possible presence of moisture. The slow rise is due to the moisture molecules slowly detaching from the pipe surface and starting to expand in the vacuum void. This is why the vacuum must be held for a time. Installation time and commissioning schedules often affect the time available for the ideal vacuum procedure. It cannot be reinforced enough that an effective vacuum process is critical to the system’s long term operation and warranty compliance.
• When possible it is preferable to use copper lines for evacuation purposes, as gauge hoses are porous when trying to measure accurate deep vacuum.
VACUUM MEASUREMENT COMPARISONS
1 TORR = 1mm HG
1 TORR 1000 = 1000 microns
microns 1000 = 29.88” HG (inches or mercury)
microns = 1mm HG
1. Connect the vacuum pump, check valve, vacuum gauge, charge line with the access cores removed and pull an initial vacuum of 1000 microns. Hold vacuum for 1 to 2 hours and monitor.
2. Break vacuum with dry nitrogen to 1 to 2 bars and release nitrogen.
3. Evacuate to 500 microns or less. Hold and monitor for 1 to 2 hours.
4. Break vacuum with dry nitrogen to 1 to 2 bars and release nitrogen.
5. Refit access valve cores. Evacuate down to best vacuum as close to 200 microns as possible. Hold for 8 hours.
6. Add additional refrigerant while system is under vacuum (as calculated from pipe lengths). Open outdoor unit isolation valves. System should now be ready for commissioning.
06. RECOMMENDED TRIPLE EVACUATION PROCEDURE
NOTE: BDT reserves the right to cut sections of pipe open and inspect if there is any doubt dry nitrogen has not been purged through the pipe work during the welding of any copper connections.

Note3. Indoor capacity is described as its model size; For example, PEFY-P32VMA-E, its capacity is P32;Note4. Total down-stream Indoor capacity is the summary of the model size of Indoors downstream. For example, PEFY-P25VMA-E+PEFY-P32VMA-E: Total Indoor capacity=P25+P32=P57Note5. Piping sized determined by the Total down-stream indoor capacity is NOT necessary to be bigger than the up-stream one. i.e. A>=B; A>=C>=D
Note1. No Joint after Header; Piping direct to Indoor Unit from Header;Note2. As bends cause pressure loss on transportation of refrigerant, fewer bends design is better;
Piping length needs to consider the actual length and equivalent length which bends are counted.Equivalent piping length (m)=Actual piping length+"M" x Quantity of bends.

Seismic Restraints and mounting of outdoor units
All units have been tri-axial shake table tested in accordance with ICC-ES AC 156 using the standard anchor bolt mounting
positions. However, local council regulations relating to seismic mounting may call for additional requirements. Please always
confirm and comply with your local regulations and standards.
NOTE: If anti vibration mounts are required it must be in the form of absorption/isolation pads.
Under no circumstances should spring type mounts be used.

noitadnuoF .3-1-4noituac lareneG .1-1-4A. 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 neighbouring properties.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 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 injuries.
B. The unit must be installed according to the instructions in order to minimise the risk of damage from earthquakes, storms, or strong winds.

Installation of the M-Net is an essential part of any City Multi installation. The wiring itself is simple but there are a number of
basic rules that must be followed to avoid communication problems within the system.
ALWAYS FOLLOW THE PIPING AND WIRING SCHEMATICS
• There are two separate M-Net control daisy chains in most City Multi installations:
1. The first M-Net starts from TB3 on the first outdoor unit, it is 24-30VDC and daisy chains between outdoor units, branch controller and indoor units within that system. Star point connections are not acceptable except when wiring in a sub BC and must have only one star point connection leading to the sub BC (as shown on the piping and wiring schematic).
2. The second M-Net starts from TB7 on the first outdoor unit, it is 22-28VDC and daisy chains from system/central controllers and all other outdoor units on all systems that are connected to the central controller. Star point connections are not acceptable.
• Each M-Net shield must be earthed in one place only. Multiple earths can cause the shield to act like an aerial, causing communication problems.
• M-Net wiring must be kept separate from other wiring to avoid induced noise.
M-Net Wiring
RECOMMENDED M-NET WIRING PROCEDURE
45
Vector Office Building - Auckland
1. Follow all pertinent wiring regulations and safety procedures.
2. Transmission control cables where possible must be 50mm away from mains cable to prevent electrical noise affecting the control circuit. Do not run control and mains in the same conduit.
3. Earth and neutral connection and testing back to MCC must be carried out by an electrician prior to powering up the outdoor unit.
4. Do not connect 230 volts to M-Net connection. This will result in catastrophic board failure.
5. Two core screened 1.25mm2 cables must be used for all M-Net wiring. Failure to do so will void all warranty and cause control system errors.
Royal Thai Embassy, Wellington
RECOMMENDED M-NET WIRING PROCEDURE – CABLE LIMITATIONS AND SYSTEM EXAMPLES
46
All City Multi equipment that sits on the M-Net requires a numerical address. This address allows
the system to identify, control, log and allocate faults to an individual piece of equipment.
Addressing must be completed at the time of installation prior to commissioning.
The address setting is generally carried out by the installation electrician as the addressing rotary
switches are located in or close to the electrical terminal boxes.
The piping installer must clearly identify and label each item of plant with permanent marker or
other labelling system with the following:
• Address
• Indoor/Outdoor/BC Name
• Port Number (R2 equipment only)
ADDRESSING MUST FOLLOW THE PIPING AND WIRING SCHEMATICS.
Rotary Switch Operation
Addresses are set using numerical rotary switches. There are two rotary tumblers for address setting
- the 10’s and the 1’s. For R2 indoor units a port setting is required. This tumbler can be set from 1
to 16. For this tumbler, A=10, B=11, C=12, D=13, E=14, F=15 and 0=16.
NOTE: Be sure power is off before setting address settings.
Ensure no two addresses are the same as this will cause a fault and the system will not operate.
Rotary Switches
M-NET ADDRESSING
49
PIPING AND WIRING SCHEMATICS
Piping and wiring schematics are essential to any new installation. The installer must have these on site
during the installation and follow them closely.
The schematics identify:
• Project name
• BDT quote number
• Equipment model numbers
• Group names
• Piping layout and sizes
• Wiring layout
• M-Net addresses
An A3 piping and wiring schematic for this project is located in the sleeve at the back of this booklet.
If the installation varies from this schematic in any way it should be identified on the schematic and
returned to BDT to re-write into an as-built schematic of the system on completion of installation.
A copy of the as-built piping and wiring schematics should be left on site as a reference for fault finding,
maintenance or servicing of the equipment if required in the future.

3-3. Refrigerant charging calculation
(1) Calculation of additional refrigerant charge Calculate the amount of additional charge based on the length of the piping extension and the size of the refrigerant line. Use the table to the below as a guide to calculating the amount of additional charging and charge the system accordingly. If the calculation results in a fraction of less than 0.1kg, round up to the next 0.1kg. For example, if the result of the calculation was 12.33kg, round the result up to 12.4kg.
At the time of shipping, the outdoor unit is charged with the refrigerant. As this charge does not include the amount needed for extendedpiping, additional charging for each refrigerant line will be required on site. In order that future servicing may be properly provided, always keep a record of the size and length of each refrigerant line and the amount of additional charge by writing it in the space provided on the outdoor unit.

• All AHU additional refrigerant calculations must be completed by BDT. The calculation is based on the AHU coil volume (BDT has this data).
• Additional refrigerant can be charged into the system while under a vacuum. In some situations the system will equalise to the bottle pressure before all of the additional refrigerant is in the system. The remaining refrigerant can be charged in to the low side of the system while it is running on either heating or cooling during the initial commissioning process.
• Any additional refrigerant must be liquid charged into the system.
• Additional refrigerant levels should be noted on each outdoor unit.

In some low load situations low operating frequency chatter can cause noise concerns. In these situations adjusting the
minimum operating frequency may be the best option and will remove this low frequency chatter. However, it is important
to know that this may also reduce the minimum operating capacity of some indoor units causing them to have less accurate
temperature control.

S, Y and WY series units all have the ability to automatically change operating mode from heating to cooling.
There are a number of auto changeover options depending on the system controllers or application.
1. Factory settings
There is no auto changeover available.
The first indoor unit to operate will select the operation mode of the outdoor unit (heating or cooling). The outdoor unit will
remain in this mode until all indoor units are either turned off or have been selected to operate in the opposite mode.
2. Auto changeover - selected from the outdoor unit
This feature will put the indoor unit that has been set to the lowest M-Net address as the master unit. Auto mode will become
available through the wall controller and the outdoor unit will change operation mode (heating or cooling) based on this units’
heating or cooling requirements. All other indoor units will display the same operation mode as this lead unit.
PUHY-P***YHM/YJM set SW4-5 to the “ON” position on the outdoor control board.
PUHY-P***YKB/YLM function 781 set SW6-10 “ON” then SW4-1,3,4,9,10 to “ON” and press and hold SWP1 for 2 sec
LED3 will become lit to indicate the function is now on.
Set SW6-10 back to “OFF”.
PUMY-P***(V)YHMB set SW2-5 to the “ON” position on the outdoor control board.
PUMY-P***VKM set SW9-1 to the “ON” position on the outdoor control board.
3. Auto changeover – selected from the central controller with web browser
This is only available on central controllers that have a web browser feature.
Using one of these controllers gives two additional auto changeover control options.
• Weighted average This looks at the heating and cooling demand of all indoor units within the system at a 15 minute interval. Once the total demand for the opposite operation mode is greater than 50% the outdoor unit will switch operation mode (heating or cooling).
• Represented group This feature allows you to select any group as the master. The lowest addressed unit within the group will decide whether the system will operate in heating or cooling mode based on the heating or cooling requirements of that unit. The wall controller will display heat or cool (not auto) but will automatically change when the temperature requirements are calling for the opposite mode. All other indoor units will display the same operation mode as this lead group.
