  • Page 51: Installation

    2. Installation (1) 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 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.

  • Page 55 (4) Connecting refrigerant pipes and drain pipes (4)-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.
  • Page 56 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.
