N O T E
• To prevent contamination of the refrigerant by water or foreign materials, do not expose the refrigerant parts open to
atmosphere for long periods. If necessary, seal pipe ends using caps or tape.
• Remove the cap for compressor right before replacing the compressor. When replacing the compressor, seal the tape
at the suction and the discharge pipes to prevent foreign materials. Remove it when brazing pipes.
• Securely check terminal numbers and mark bands before disconnecting lead wires. When reassembling the lead wires,
connect them to match surely the terminal numbers and the mark bands. If the lead wires are connected incorrectly to
the terminal, the compressor will be damaged due to reverse rotation.
