Refrigerant Oil: Service and Repair

REFRIGERANT LEVEL CHECK, DRAINING, AND CHARGING

REFRIGERANT LEVEL TEST

Use the refrigerant recovery station to remove all of the refrigerant, and then calculate the amount of the refrigerant and charge it.

NOTE:
Refer to the Refrigerant Recovery and Recycling Unit's Instruction Manual for operation of the unit.

METHOD BY USING REFRIGERANT RECOVERY AND RECYCLING UNIT

Using the refrigerant recovery and recycling unit, refill the refrigerant.

NOTE:
Refer to the Refrigerant Recovery and Recycling Unit's Instruction Manual for operation of the unit.

DISCHARGING SYSTEM

Use the refrigerant recovery unit to discharge refrigerant gas from the system.

NOTE:
Refer to the Refrigerant Recovery and Recycling Unit's Instruction Manual for operation of the unit.

CHARGING

Use the refrigerant recovery station to charge the refrigerant.

NOTE:
Refer to the Refrigerant Recovery and Recycling Unit's Instruction Manual for operation of the unit.

REFILLING OF OIL IN THE A/C SYSTEM

Too little oil will provide inadequate compressor lubrication and cause a compressor failure.
Too much oil will increase discharge air temperature.

When a compressor is installed at the factory, it contains 80 cm3 (4.7 fl.oz) of refrigerant oil. While the A/C system is in operation, the oil is carried through the entire system by the refrigerant. Some of this oil will be trapped and retained in various parts of the system.

When the following system components are changed, it is necessary to add oil to the system to replace the oil being removed with the component.

Compressor oil: SUN PAG 56


Quantity:

Evaporator: 60 cm3 (2.0 fl.oz)
Condenser: 15 cm3 (0.5 fl.oz)
Suction hose: 10 cm3 (0.3 fl.oz)
