The suction accumulator/drier should be replaced when:
1. Unit is restricted, plugged or perforated.
2. System has been left open for 1-2 months.
3. There is evidence of moisture in system such as internal corrosion of metal lines or dark, thick refrigerant oil.
4. There are more than 5 ounces of refrigerant oil in suction accumulator/drier indicating bleed hole is clogged.

Do not replace suction accumulator/drier each time the following condition exists:
1. There is a loss of refrigerant charge.
2. A component such as a condenser, evaporator or compressor is replaced.
3. A dent is found in outer shell of suction accumulator/drier.




1. Discharge refrigerant from system.
2. Disconnect electrical connector from pressure switch and remove switch.
3. Disconnect suction hose from accumulator and cap suction hose.
4. Loosen fitting connecting accumulator to evaporator core.
5. Remove accumulator strap to mounting bracket attaching screw.
6. Disconnect accumulator from evaporator core and remove strap from accumulator.
7. Reverse procedure to install. Use new O-ring lubricated with refrigerant oil. When replacing suction accumulator in a refrigerant system that contains a six cylinder compressor, add one ounce of refrigerant oil to the accumulator.
