4. Cleaning The Suction Filter
(1) Perform a pump down operation to reduce pressure inside the compressor.
(2) Release the internal pressure of the compressor.
Loosen the flare nut of the service port (with check valve) of the compressor (see Fig. 3-2).
Remove the partition lid, then tighten the flare nut to discharge refrigerant from the
compressor. (Same as Section 3.2.2)
(3) Disconnect the suction pipe, and remove the suction filter.
(4) Remove dust and foreign particles from the inside of the filter by using compressed air and
cleaning solution. Check the filter thoroughly for tears and damage. (Replace the filter if
there is a tear.) Dry the filter thoroughly before installation to remove cleaning solution and
moisture.
