Thermal Protector Replacement
1. Removal of discharge valve body
Remove the bolts and carefully remove the discharge valve
body. .-
2. Removal of snap ring and thermal protector
Note
l When removing the thermal protector, do not pull
the harness wires but push the protector out from
its back side.
23UOUX-028 3. Installation of thermal protector
1) Check that the O-ring groove is free from foreign matter.
Apply compressor oil to the O-ring and properly fit it in
the groove.

ing face of the compressor with cleaning solvent.
Caution
l Keep the cleaning solvent and dirt out of the com-
pressor.
l Do not use any cloth for cleaning.
Clean only by rinsing with the solvent.
l Do not spill the refrigerant oil from the compressor.
Refill the same amount of the oil if the oil is spilled
out.
