Refrigerant Oil: Capacity Specifications
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.
Both HR6 and V-5 compressor systems require 240 ml (8 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 1 fl. oz. is drained - add 2 fl. oz. to the new compressor.
^ If more than 1 fl. oz. is drained - add same amount that was drained to the new compressor.
b. Accumulator Dehydrator
^ Add 3.5 fl. oz. to new accumulator.
c. Evaporator
^ Add 3 fl. oz. oil.
d. Condenser.
^ Add 1 fl. oz. oil.
e. Refrigerant oil loss due to a large leak.
^ If the refrigerant charge is abruptly lost due to a large refrigerant leak, approximately 3 fl. oz. of refrigerant oil will be carried out of the system
suspended in the refrigerant. Any failure that causes an abrupt refrigerant discharge will experience this oil loss. Failures that allow the
refrigerant to seep or bleed off over time do not experience this oil loss.
^ Upon replacement of a component which caused a large refrigerant leak, add 3 fl. oz. of new' 525 viscosity refrigerant oil plus:
-
The required amount of oil for the particular component (as outlined above).
-
Add the oil directly to the replaced component if possible. If the oil cannot easily be added to the replaced part, add the oil to the
accumulator.
