12. ELECTRICAL WORK AIR TO WATER
12. ELECTRICAL WORK12-1. General cautions
Electrical work should be done by qualified electrical engineers in accordance with "Engineering Standards For ElectricalInstallation" and supplied installation manuals. Special circuits should also be used. If the power circuit lacks capacity orhas an installation failure, it may cause a risk of electric shock or fire.
1) Be sure to take power from the special branch circuit.2) Be sure to install an earth leakage breaker to the power.3) Install the unit to prevent that any of the control circuit cables (remote controller, transmission cables, or external input/
output line) is brought in direct contact with the power cable outside the unit.4) Ensure that there is no slack on all wire connections.5) Some cables (power, remote controller, transmission cables external input/output line) above the ceiling may be bitten
by mouses. Use as many metal pipes as possible to insert the cables into them for protection.6) Never connect the power cable to leads for the transmission cables. Otherwise the cables would be broken.7) Be sure to connect control cables to the indoor unit, remote controller, and the outdoor unit.8) Be sure to ground the unit.9) Select control cables from the conditions given in P43.
Be sure to put the unit to the ground on the outdoor unit side. Do not connect the earth cable to any gas pipe, water pipe,lightening rod, or telephone earth cable. Incomplete grounding may cause a risk of electric shock.
12-2. Power supply for PWFY unit

12-5. Connecting electrical connections
Verify that the model name on the operating instructions on the cover of the control box is the same as the model nameon the nameplate.
Remove the screws holding the terminal box cover in place.
Ensure that the wiring is not pinched when fitting the terminal box cover. Pinching the wiring may cut it.
Install wiring so that it is not tight and under tension. Wiring under tension may break, or overheat and burn.
Fix power source external input/output line wiring to control box by using buffer bushing for tensile force to prevent electric shock. (PG connection or the like.) Connect transmission wiring to transmission terminal block through the knockout hole of control box using ordinary bushing.After wiring is complete, make sure again that there is no slack on the connections, and attach the cover onto the control box in the reverse order removal.

(Be sure to operate with the main power turned OFF.)<Address board>
13-2-1. Switch operation (BC controller)There are two types of rotary switch setting available: setting addresses 1 to 9 and over 10, and setting branch numbers.a) How to set addresses
Example: If Address is "3", SWU2 (for over 10) remains at "0", and match SWU1 (for 1 to 9) to "3".b) How to set branch numbers SWU3 (only for R2/WR2-Series)
Branch number matches the BC controller branch number. If two branches are used, SWU3 should be set to a smallerbranch number. For other than R2/WR2-Series, remain SWU3 as "0".

13-2-2. Switch operation (WCB)a) How to set addresses
Example: If Address is "3", SWU2 (for over 10) remains at "0", and match SWU1 (for 1 to 9) to "3".b) How to set branch numbers SWU3 (only for R2-Series)
There are two branches for WCB. Indoor unit/PWFY connecting branch should be set as "0" and PWFY connectingbranch as "1".

15-2. Selecting an installation site
Do not install outdoors. The unit is not waterproof. Back up system is recommended in case of PWFY unit breakdown. The unit will get hot. Do not install in a location where heat gets trapped inside. Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal injury. Do not install the unit where corrosive gas is generated. Have installation work in order to protect against earthquake.
Any installation deficiency may cause unit to fall down, resulting in a personal injury. Pay a special attention to the place, such as a basement, etc. where refrigeration gas can stay, since refrigeration is
heavier than the air. Do not install the unit where combustible gas may leak.
- If the gas leaks and accumulates around the unit, an explosion may result. When installing the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.
- The inverter equipment, private power generator, high-frequency medical equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditionermay affect such equipment by creating noise that disturbs medical treatment or image broadcasting.
Do not install the unit on a structure that may cause leakage.- When the room humidity exceeds 80% or when the drain pipe is clogged, condensation may drip from the indoor unit.
Perform collective drainage work together with the unit, as required. It is recommended that a water pump is connected to each PWFY unit.
15-3. Securing installation and service space
Please secure the following service spaces after installation.(All servicing can be performed from the front of the unit)
Be sure to install the unit in a location which can adequately support its weight.- If there is insufficient strength to support the unit's weight, it could fall and cause injuries.

15-6. Connecting refrigerant pipes and drain pipes15-6-1. Refrigerant piping work
This piping work must be done in accordance with the installation manuals for both outdoor unit and BC controller/WCB (simultaneous cooling and heating R2-Series). R2-Series is designed to operate in a system that the refrigerant pipe from an outdoor unit is received by BC controller/
WCB and branches at the BC controller/WCB to connect between indoor units. The PWFY unit should be connected to 2 ports on the BC controller. (Set BC controller DIP SW 4-6 to ON) For constraints on pipe length and allowable difference of elevation, refer to the outdoor unit installation manual. The method of pipe connection is brazing connection.
Install the refrigerant piping for the indoor unit in accordance with the following.1) Cut the tip of the indoor unit piping, remove the gas, and then remove the brazed cap.
2) Pull out the thermal insulation on the site refrigerant piping, braze the unit piping, and replace the insulation in its originalposition. Wrap the piping with insulating tape.
Pay strict attention when wrapping the copper piping since wrapping the piping may cause condensation instead of preventing it. Before brazing the refrigerant piping, always wrap the piping on the main body, and the thermal insulation piping, with
damp cloths to prevent heat shrinkage and burning the thermal insulation tubing. Take care to ensure that the flame does not come into contact with the main body itself.
15-6-2. Mixed system of PWFY-AU and Indoor unit (Y, HP (ZUBADAN), WY system)
Take one of the countermeasures listed below. 1) Install the External Solenoid Valve (except on PWFY-EP100VM-E2-AU)2) Add brine, assuming that the temperature will drop to -20°C.
Set Dip SW 1-10 (on ATW unit) to ON if brine is added. *Refer to P62 “Brine” in section 15-7. Water pipe installation.
* With the WY system, the above steps apply only when operating the WY at the water temperature below 10ºC.

Cautions On Refrigerant Piping
Be sure to use non-oxidative brazing for brazing to ensure that no foreign matter or moisture enter into the pipe. Be sure to apply refrigerating machine oil over the flare connection seating surface and tighten the connection using a
double spanner. Provide a metal brace to support the refrigerant pipe so that no load is imparted to the indoor unit end pipe.
This metal brace should be provided 500 mm away from the indoor unit's flare connection.
When installing and moving the unit, do not charge it with refrigerant other than the refrigerant (R407C or R22) specified on the unit.
- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to malfunction and result in severe damage.
Use refrigerant piping made of C1220 (CU-DHP) phosphorus deoxidized copper as specified in the JIS H3300 "Copper and copper alloy seamless pipes and tubes". In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant. Never use existing refrigerant piping.
- The large amount of chlorine in conventional refrigerant and refrigerator oil in the existing piping will cause the newrefrigerant to deteriorate.
Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing.- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and the compressor may fail.
15-6-4. Drain piping work
1) Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor (discharge) side. Do not provide any trap or irregularity on the way. (a)
2) Ensure that any cross-wise drain piping is less than 20 m (excluding the difference of elevation). If the drain piping islong, provide metal braces to prevent it from waving. Never provide any air vent pipe. Otherwise drain may be ejected.
3) Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm) for drain piping.4) Ensure that collected pipes are 100 mm lower than the unit body's drain port as shown in (b).5) Do not provide any odor trap at the drain discharge port.6) Put the end of the drain piping in a position where no odor is generated.7) Do not put the end of the drain piping in any drain where ionic gases are generated.

15. INSTALLATION AIR TO WATER
Caution for water pipe installation
Consider the following when designing and installing a water piping system. Do not use steel pipes as water pipes.
- Copper pipes or stainless steel pipes are recommended. If iron pipes are used in the existing system, do not connecta new circuit to the old one. Keep the existing and new circuits separate.
Light pipes are similar to other air-conditioning pipes, however, please observe the following precautions during installation. Before a long period of non use, purge the water out of the pipes and thoroughly let them dry. Use a closed water circuit. When operating the unit, add brine to the circulating water to prevent it from freezing. To use brine in the system, DipSW 1-10
must be set to ON. When installed in a low-ambient temperature environment, keep the water circulating at all times. If that is not possible, purge
the water out of the pipes completely. Do not use the water used for this unit for drinking or food manufacturing. When the ambient temperature is 0 °C or lower during stop operation, keep the water circulating at all times, or purge the water
out of the pipes completely.
Selecting a water pumpUse a pump that is large enough to compensate for the total water pressure loss and to supply sufficient water to the unit.
Installing the strainer Install the strainer at the angle of 45˚ or less as shown in [Fig. 3-1-A]. Install the supplied strainer at the water inlet.
Precautions during installation
Use the reverse-return method to insure proper pipe resistance to each unit. To insure easy maintenance, inspection, and replacement of the unit, use a proper joint, valve, etc. on the water intake and
outlet port. In addition, be sure to install a strainer on the water intake pipe. (In order to maintain the heat source unit, a strainer on the circulating water inlet is necessary.)* An example of the heat source unit installation is shown in [Fig. 3-1-B]. Install a suitable air vent on the water pipe. After sending water through the pipe, be sure to vent the excess air. Condensed water may form in the low-temperature sections of heat source unit. Use a drainage pipe connected to the drain
valve at the base of the unit to drain the water. Install a back flow-prevention valve on the pump and a flexible joint to prevent excess vibration. Use a sleeve to protect the pipes where they go through a wall. Use metal fittings to secure the pipes, and install them so that they have maximum protection against breakage and bending. Do not confuse the water intake and outlet valves. This unit doesn't have any heater to prevent freezing within tubes. When the water flow is stopped on low ambient, take out the
water from tubes. The unused knockout holes should be closed and the opening of refrigerant pipes, water pipes, power source and transmission
wires should be filled with putty and so on to prevent from moisture or the invasion of insects. (field construction) Wrap some sealing tape around the screw part to prevent water leakage. Wrap the sealing tape as follows.
1) Wrap the joint with sealing tape in the direction of the threads (clockwise), and do not let the tape run over the edge.2) Overlap the sealing tape by two-thirds to three-fourths of its width on each turn. Press the tape with your fingers so that it is
pressed firmly against each thread.3) Leave the 1.5th through 2nd farthest threads away from the pipe and unwrapped. Hold the pipe on the unit side in place with a spanner when installing the pipes or strainer.
Tighten screws to a torque of 50 N.m. Water pipes can get very hot, depending on the preset temperature. Wrap the water pipes with insulating materials to prevent
burns. Install the expansion joint (accessory) at the inlet after installing the strainer, and outlet.

15. INSTALLATION AIR TO WATER
Water processing and water quality control
To preserve water quality, use the closed type of cooling tower for unit. When the circulating water quality is poor, the waterheat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion of the heat exchanger. Please pay careful attention to water processing and water quality control when installing the water circulation system.Removal of foreign objects or impurities within the pipes.During installation, be careful that foreign objects, such as welding fragments, sealant particles, or rust, do not enter the pipes.Water Quality Processinga) Depending on the quality of the cold-temperature water used in the air-conditioner, the copper piping of the heat
exchanger may become corroded. We recommend regular water quality processing.Cold water circulation systems using open heat storage tanks are particularly prone to corrosion.When using an open-type heat storage tank, install a water-to-water heat exchanger, and use a closed-loop circuit onthe air conditioner side. If a water supply tank is installed, keep contact with air to a minimum, and keep the level ofdissolved oxygen in the water no higher than 1mg/liter.
b) Water quality standard
Reference: Guideline of Water Quality for Refrigeration and Air Conditioning Equipment. (JRA GL02E-1994)c) Please consult with a water quality control specialist about water quality control methods and water quality calculations
before using anti-corrosive solutions for water quality management.d) When replacing a previously installed air conditioning device (even when only the heat exchanger is being replaced),
first conduct a water quality analysis and check for possible corrosion.Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion.If the water quality level has dropped, please adjust water quality sufficiently before replacing the unit.Refer to the belowgraph for the maximum amount of circulating water in the water pipe. Make sure that this amount does not exceed.

Pump interlock
The unit may become damaged if it is operated with no water circulating through the pipes.Be sure to interlock unit oper-ation and the water-circuit pump. In the system including PWFY-P100VM-E-BU, use the terminal blocks for interlocking TB142A (IN1) that can be found onthe unit.
In the system including PWFY-EP100VM-E1/E2-AU, the circulating water may freeze, and result in a unit malfunction.Perform the electrical work as shown in [Fig. 3-1-F] to prevent water from freezing.Set the Dip SW as shown in the tablebelow.
Be sure to turn on the power supply of the pump, since the control does not work if the power supply of the pump is turnedoff.*Refer to P59 “Flow switch installation” for details.

15. INSTALLATION AIR TO WATER
In a system that includes PWFY-EP100VM-E1-AU, if the operation of the pump is interlocked with the operation of the airconditioning units AND if the Solenoid valve kit (PAC-SV01PW-E) is connected to the system, connect the wires as shownin [Fig. 3-1-G]. Set Dip SW3-6 to ON, and make sure that the version of the software is 1.18 or later. (PWFY-EP100VM-E2-AU do not need a solenoid valve kit because they are built in with the same functions.)
Anti freeze mode (Dip SW4-4 ON)
Anti freeze mode is to prevent water pipe from freezing.The Anti freeze mode can set the heating temperature range be-tween 10ºC~45ºC enabling the unit to maintain low water temperature to prevent water pipes from freezing.
