TURN OFF all the power switches.
2.14.1 Removing High Pressure Switch (PSH1 and PSH2)
(1) Collect the refrigerant.
(2) Disconnect the fasten terminals.
(3) Remove the high pressure switch from the brazing part of the discharge pipe with a burner.
NOTE:
1. To prevent water and foreign particles from entering the refrigerant cycle, mount the new high pressure switch
immediately after removing the old one. If it is impossible by necessity, seal the hole with tapes.
2. Check that the RC cover inner side (aluminium sheet) does not contact the terminals of the high pressure switch.
3. Make sure to x the insulating sleeve of the fasten terminals as shown in the gure. If the terminals of the high
pressure switch are exposed and contact with the RC cover, the electrical components may be damaged.
