N O T E
• Compressor piping must be connected by brazing. MAKE SURE that any flammable material is not around before
heating with burner for the oil inside the piping may flame up.
• Do not expose the refrigerant cycle to the atmosphere for a long period to avoid moisture or dust into the cycle. Be sure
to replace the compressor immediately after removing. Seal the suction and discharge pipes when the refrigerant cycle
is left unattached for a long period.
• Remove the cap of new compressor right before the replacement. Before mounting the compressor seal the suction
and discharge pipes with a tape to protect the compressor from dust. Remove the tape when blazing the pipe.
• For piping at reassembling ensure that the compressor terminal numbers and wiring mark band codes are matched.
Incorrect wiring numbers may result in inverse rotation and damage of the compressor.
6 Remove the suction pipe and discharge pipe from the compressor.
N O T E
Be sure to separate the blazing burner flame sufficiently from the wires and electrical components around the brazed part
in order to avoid burning.
