Refrigerant Oil Distribution

The HR-6 compressor system requires 240 ml (8 fl. oz.) of PAG refrigerant oil.

New oil must be added to the system when components are replaced, as follows:
^ Compressor - Remove the compressor and drain the oil. Measure the oil removed and if more than 30ml (1 fl. oz.) is drained, replace it with the same amount of new oil. If less than 30 ml (1 fl.oz.) of new oil.
^ Evaporator - Add 90 ml (3 fl. oz.)
^ Condenser- Add 30 ml (1 fl. oz.)
^ Accumulator - Add 105 ml (3.5 fl. oz.)
The accumulator should only be replaced when a physical perforation to the shell is found resulting in a leak, the O-ring seat is damaged, or the inlet(outlet line fitting threads are damaged.

With signs of extensive oil leakage:
^ Remove the accumulator. Drain, measure and record quantity of oil in accumulator.
^ If amount of oil drained is less than 90 ml (3 oz.), add 90 ml (3 oz.) of new oil to the system.
^ If amount of oil drained is more than 90 ml (3 oz.), add same amount of new oil as drained.

On-Vehicle Set Up
CAUTION:
^ Always wear goggles and gloves when doing work that involves opening the refrigeration system. If liquid refrigerant comes into contact with the skin or eyes, injury may result
^ Use only authorized 23kg (50 lbs.) refillable refrigerant tanks (J 39500-50). Use of other tanks could cause personal injury and void the warranty.
1. Connect high side (red) and low side (blue) hoses to their respective service ports on the vehicle.
2. Refer to the ACR4 Instruction Manual for all initial setup procedures and operating instructions.
