2. Installation (1) Selectng an nstallaton ste • 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 refrigera- tion 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.

(4) Connecting refrigerant pipes and drain pipes (4)-1 Refrgerant ppng 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.
Page 61
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. e 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. Warning: 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. Caution: • 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 new refrigerant to deteriorate.

<Installation procedures> 1) Remove the pipes attached to the flow switch. Note: The unit is shipped with the pipes loosely tightened. 2) Wrap seal tape around the threads at the end of the pipes, starting at the 1.5th or 2nd thread, and not over the openings.
If the water quality level has dropped, please adjust water quality sufficiently before replacing the unit. Refer to the below graph for the maximum amount of circulating water in the water pipe. Make sure that this amount does not exceed. [Fig. IV. 3. (8).1] Maximum circulating water PWFY-P100VM-E-BU PWFY-P100/200VM-E1-AU 3000 2500...

The unit may become damaged if it is operated with no water circulating through the pipes. Be sure to interlock unit operation 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 on the unit.
In a system that includes PWFY-P100/P200VM-E1-AU, if the operation of the pump is interlocked with the operation of the air conditioning units AND if the Solenoid valve kit (PAC-SV01PW-E) is connected to the system, connect the wires as shown in [Fig. IV.3.(10).3]. Set Dip SW3-6 to ON, and make sure that the version of the software is 1.18 or later. [Fig.
