V. REMOVAL AND REPLACEMENT1. SERVICE FOR REFRIGERANT LINES[a] SERVICE INFORMATION1) Allowable Compressor Opening Time and Prevention of Lubricant Mixture [R404A]The compressor must not be opened more than 15 minutes in replacement or service. Donot mix lubricants of different compressors even if both are charged with the samerefrigerant, except when they use the same lubricant.2) Treatment for Refrigerant Leak [R404A]If a refrigerant leak occurs in the low side of an ice maker, air may be drawn in. Even if thelow side pressure is higher than the atmospheric pressure in normal operation, acontinuous refrigerant leak will eventually lower the low side pressure below theatmospheric pressure and will cause air suction. Air contains a large amount of moisture,and ester oil easily absorbs a lot of moisture. If an ice maker charged with R404A haspossibly drawn in air, the drier must be replaced. Be sure to use a drier designed forR404A.3) Handling of Handy Flux [R404A]Repair of the refrigerant circuit requires brazing. It is no problem to use the same handyflux that has been used for the current refrigerants. However, its entrance into therefrigerant circuit should be avoided as much as possible.4) Oil for Processing of Copper Tubing [R404A]When processing the copper tubing for service, wipe off oil, if any used, by using alcohol orthe like. Do not use too much oil or let it into the tubing, as wax contained in the oil will clogthe capillary tubing.5) Service Parts for R404ASome parts used for refrigerants other than R404A are similar to those for R404A. Butnever use any parts unless they are specified for R404A because their endurance againstthe refrigerant have not been evaluated. Also, for R404A, do not use any parts that havebeen used for other refrigerants. Otherwise, wax and chlorine remaining on the parts mayadversely affect R404A.6) Replacement Copper Tubing [R404A]The copper tubes currently in use are suitable for R404A. But do not use them if oily inside.The residual oil in copper tubes should be as little as possible. (Low residual oil typecopper tubes are used in the shipped units.)30
