Maintenance of Lubricant Quantity in CompressorEJS000TH
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large gas leakage occurred. It is important to maintain the speci-
fied amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
●Lack of lubricant: May lead to a seized compressor
●Excessive lubricant: Inadequate cooling (thermal exchange interference)

Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check the appearance of the pulley assembly. If the contact surface
of pulley sows signs of excessive grooving, replace clutch disc and
pulley. The contact surfaces of the pulley assembly should be
cleaned with a suitable solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.
INSTALLATION
With Gasoline Engine (CWV-615M Compressor)
1. Install the field coil.
Be sure to align the coil's pin with the hole in the compressor's
front head.
