Install or Connect

1. Polyalkaline glycol (PAG) refrigerant oil.
^ If compressor is being replaced, drain refrigerant oil from both defective compressor and new compressor. Oil must be drained through the crankcase drain plug and suction/discharge ports. Measure amount removed from defective compressor. If measured amount is less than 30 ml (1 fluid ounce), add 60 ml (2 fluid ounces) to new replacement compressor. If more than 30 ml (1 fluid ounce) is drained from defective compressor, add same amount to new compressor. Use PAG refrigerant oil only.
2. Rear bracket and bolts/screws, if removed.

Tighten
^ Bolts/screws to 25 N.m (18 lb. ft.).
