10.2.4 Removing the compressor
N O T E
• 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 to the suction and discharge pipes when
the refrigerant cycle is left unattached for a prolonged time.
• 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 at pipe con-
nection.
• To connect wiring 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 the compressor.
