Any process in where the HCFC's refrigerant or the
different kind of oil against the defined. Compressor oil
are mixed should be avoided.
The running operation that inspection and the protector
inspection that affect a damage to the function and
durability of the compressor should be avoided
When the outdoor unit is operated with the indoor
dummy unit, the discharged oil should be recovered
enough
Always purge the system and the compressor with the
dry nitrogen in order to prevent oxidation of the piping
When charging refrigerant into the cycle, make sure that
refrigerant always be filled from the higher pressure side
(condenser exit) of the cycle.
If liquid refrigerant is sucked in to the compressor liquid
compression occurs, The discharge valve is damaged,
lubrication effectiveness degenerates and reliability drops lubrication effectiveness degenerates and reliability drops
noticeably
Do not operate the compressor in a vacuum state.
Furthermore do not apply high voltage to a vacuum state
compressor. There is a danger that insulation could
degenerate, causing electric shock
Do not compress the air including the case of leakage in
the refrigeration cycle. If compressors run with air mixed,
inside the compressor is heated and pressurized , which
may cause an explosion
After removing rubber plugs from compressor tubes,
Promptly use the compressor. And do not leave in the
atmosphere for 10 minutes over. If Air gets into the
compressor , accelerating degeneration of the inside of
the cycle or compressor
Wires connected to the compressor, follow the
compressor specification manual and instructions
-10℃ ~ 65℃
Use compressor with grounded system only.
