SAFETY PRECAUTIONS DWARNING: D DENSO compressors are sealed, pressurized and contain factory-specified amounts of refrigerant oil used in the original design of the unit. PRIOR to removal of shipping plates or unit installation, you must read these instructions completely. • Always wear safety goggles. • Avoid skin contact with refrigerant or refrigerant oil. • Work in a well-ventilated area. • Never release refrigerant into the atmosphere.

Service Valve Installation NOTE: Not all DENSO compressors require the service valve(s) to be reused. If the compressor type does not use a separate service valve(s), it is mandatory to still verify the level of compressor lubricant. (See Fig. 1) 1. Slowly release the pressure from the Schrader valve located on the compressor shipping plate(s). 2.

Compressor Installation NOTE: Before installing the compressor, please refer to the appropriate manufacturer’s service manual for complete instructions. 1. Install the magnetic clutch to the compressor. (If applicable, refer to A/C Compressor Magnetic Clutch Installation Instructions) 2. Place the compressor on a flat surface with the service valve(s) in an upright position, hand turn the clutch pressure plate a minimum of 10 times to release lubricant from the compressor head. 3.
PAGE 5
Compressor Oil Type Compressor oil is necessary for the lubrication of the compressor bearings, moving and sliding parts. Since compressor oil circulates through the entire refrigeration cycle, manufacturer’s recommended oil must be used. The recommended oil for crankshaft and swash plate type compressors using refrigerant R-12 is ND-OIL 6. “Through vane” (TV) type compressors use a completely different oil. The recommended oil for TV type compressors using refrigerant R-12 is ND-OIL 7.
