A fitting located on the top of the suction accumulator/drier is used to attach the A/C cycling switch. A long-travel Schrader-type valve stem core
is installed in the fitting opening to prevent refrigerant loss when the A/C cycling switch is removed.
When it is necessary to measure the quantity of refrigerant oil in the suction accumulator/drier, drill two 13 mm (0.5 inch) holes in the suction
accumulator/drier and drain oil through the holes.
In addition to the preceding condition, the suction accumulator/drier should also be replaced if one of the following conditions exists:
-
The suction accumulator/drier is perforated.
-
The refrigerant system has been opened to the atmosphere for a period of time longer than required to make a minor repair.
-
There is evidence of moisture in the system such as internal corrosion of metal refrigerant lines or the refrigerant oil is thick and dark.
