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 cy-
cle. 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 connection.
• To connect wiring at reassembling ensure that the compressor terminal numbers and wiring mark band codes are mat-
ched. Incorrect wiring numbers may result in inverse rotation and damage the compressor.
