Page 73: Special Precautions For R407C
Special Precautions for R407C Special precautions when dealing with refrigerant R407C unit 1) What is New Refrigerant R407C? R407C is a zeotropic refrigerant mixture which has zero ozone depletion potential and thus conformed to the Montreal Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22. - Page 74 c) Ensure that the compressor is not exposed to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal-plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa (-700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

Page 79: Refrigerant Piping Work
Refrigerant Piping Work Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized by the perfect piping work. Piping Length and Elevation If the piping is too long, both the capacity and reliability of the unit will drop. As the number of bends increase, resistance to flow of refrigerant increases, thus lowering the cooling capacity and as a result overloading the compressor which may cause the compressor to become defective. - Page 80 Cooling only INDOOR MCK020A MCK025A MCK030A MCK040A MCK050A MODEL OUTDOOR MLC020B MLC025B MLC030C MLC040C MLC050C L <= 5 m 0.250 0.100 0.400 L = 7 m 0.280 0.176 0.600 0.100 0.100 L = 10 m 0.325 0.290 0.650 0.250 0.250 L = 15 m 0.400 0.480...
