Refrigerant piping work This piping work must be done in accordance with the installation manuals for outdoor unit. or constraints on pipe length and allowable difference of elevation, refer to the outdoor unit manual. The method of pipe connection is brazing connection. autions on refrigerant piping s e sure to use non-oxidative brazing for brazing to ensure that no foreign matter or moisture enter into the pipe. s rovide 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 50 cm away from the indoor unit s brazing connection. Warning: o not mix anything other than the specified refrigerant (R407) into the refrigerating cycle. Mixing air may cause the refrigerating cycle to get abnormally high temperature, resulting in a burst. aution: nstall the refrigerant piping for the indoor unit in accordance with the following.. Remove the cap. [ig. 7..] (.4) Remove the cap. ull out the thermal insulation on the site refrigerant piping, braze the unit piping, and replace the insulation in its original position. Wrap the piping with insulating tape. [ig. 7..] (.4) Thermal insulation ull out insulation Wrap with damp cloth Return to original position nsure that there is no gap here Wrap with insulating tape Note: ay strict attention when wrapping the copper piping since wrapping the piping may cause condensation instead of preventing it. * efore 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. aution: Use refrigerant piping made of 0 (U-) phosphorus deoxidized copper as specified in the JS 00 opper and copper alloy seamless pipes and tubes. n 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. Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. - f dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and the compressor may fail. Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections. (or models using R407) - The refrigerant used in the unit is highly hygroscopic and mixes with water and will degrade the refrigerator oil. o not use a leak detection additive. dditional refrigerant charge Take care not to allow dirt or cutting chips to enter the refrigerant pipes. The refrigerant pipes must be kept warm, so take particular care to insulate between refrigerant pipes and the gas pipe located inside the indoor unit, since the gas pipe causes condensation during cooling operation. When connecting the refrigerant pipes, make sure that the stop valve of the outdoor unit is fully closed (as it was when shipped from the factory). fter connecting all the refrigerant pipes between the indoor and outdoor units, purge air from the stop valve service port of the outdoor unit and service port of each connecting pipe. heck that there is no air leakage from any pipe connection, then fully open the stop valve of the outdoor unit. This will connect the refrigerant circuit between the indoor and outdoor units. The refrigerant pipes must be as short as possible. lare and flange connections must be used for connection of the refrigerant pipes.
