(4) Release the lace for the water-proof cover, open the water-proof cover from the front side.
NOTE:
Remove the water-proof cover in the arrow mark direction as shown by paying attention to the cut
part of the water-proof cover in order to avoid any damages.
(5) Remove the terminal cover for the compressor and disconnect the wiring to the compressor
terminals. Check to ensure that the terminals Nos. are indicated. If the terminal Nos. are not
identified, at reassembling, the compressor will fail due to reverse rotation.
NOTES:
1. Check to ensure that the faston terminals for the compressor are normal. When a pulling force of
20N or more is required, it is normal. If abnormal, replace the faston terminals with new ones.
2. Check to ensure that wires are firmly fixed.
3. It is recommended that the faston terminals be clamped to increase a contacting force after
replacing the compressor.
