10. Removing the high pressure switch (63H)
(1) Remove the service panel. (See Figure 1)
(2) Remove the top panel. (See Figure 1)
(3) Remove the electrical parts box if necessary
(Refer to procedure 3)
(4) Remove the cover panel (front). (See Figure 2)
(5) Remove cover panel (rear). (See Figure 2)
(6) Remove the valve bed. (Refer to procedure 8)
(7) Remove the side panel (R). (Refer to procedure 8)
(8) Pull out the lead wire of high pressure switch.
(9)
Disconnect the lead wire of 63H (Yellow) on the controller
circuit board.
(10) Remove the electrical parts box. (Refer to procedure 3)
(11) Loosen the clamp on the separator and unbind the lead
wires.
(12) Recover refrigerant.
(13) Remove the welded part of high pressure switch.
Note 1: Recover refrigerant without spreading it in the air.
Note 2: The welded part can be removed easily by
removing the right side panel.
Note 3: When installing the high pressure switch, cover it
with a wet cloth to prevent it from heating (100°C
