INSTALLATION

Compressor Mounting:

^ Reverse removal procedure noting the following:

1. Torque pressure lines at compressor to 26-40 Nm (20-30 ft. lbs.).

NOTICE: The 0-rings in the compressor head should be oiled prior to placement in the cavity. Care should be taken not to damage these 0-rings during installation.

2. Torque the compressor top through bolt and nut, bottom nut and generator bracket bolt to 38-50 Nm (28-37 ft. lbs.). Torque the one bolt through tubular strut into compressor to 65-85 Nm (48-63 ft. lbs.).
3. Install belt on compressor pulley and tension to 700-900 Nm (157-202 lbs.) for a new belt and 400-750 Nm (90-169 lbs.) for a used belt.
4. Evacuate and charge refrigeration system.
5. Leak test all compressor connections.

NOTICE: All leaks must be repaired. Under no circumstances should a compressor be operated when a leak exists. Loss of refrigerant prevents oil return to the compressor and operating the compressor may damage it.
