A/C System Oil Charge Replenishing

ADDING OIL
Oil should be added to the A/C system after it is discharged and before it is evacuated. Remove the refrigeration suction hose at the accumulator outlet pipe connection. Pour the right amount of new refrigerant oil into the hose or pipe, then reconnect the hose to the pipe.

REFRIGERANT OIL DISTRIBUTION
The V-5 compressor system requires 265 ml (9 fl. oz.) of 525 viscosity refrigerant oil.

New 525 viscosity refrigerant oil must be added to the system when components are replaced, as follows:

a. All Compressors (drain and measure the oil)

- If less than 30 ml (1 fl. oz.) is drained-add 60 ml (2 fl. oz.) to the new compressor.

- If more than 30 ml (1 fl. oz.) is drained-add same amount that was drained to the new compressor.

lo. Accumulator-Add 105 ml (3.5 fl. oz.) of new oil to the replacement accumulator to compensate for oil retained by original accumulator desiccant and bag assemblies. The accumulator should only be replaced if leaking due to a perforation, damaged O-ring seat, or damaged threads.

c. Evaporator-Add 90 ml (3 fl. oz.) of new refrigerant oil.

d. Condenser-Add 30 ml (1 fl. oz.) of new refrigerant oil.

NOTE: The accumulator should only be replaced when a physical perforation to the accumulator is found resulting in a leak.
