5 Open the soundproof cover wrapped around the compressor
and remove the terminal box cover of the compressor body.
Disconnect the compressor wires in the terminal box and
remove the thermistor on top of the compressor. Remove the
soundproof cover.
• Check the terminal codes and mark bands when
disconnecting the wires. Connecting wires in wrong order

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.
