Oil Filter Installation for Spin-On Type Filters
1. For compressors supplied with spin-on type oil filters, remove the old filter by
unscrewing it, with the compressor stopped. Be sure that the old filter gasket is
removed. Clean the filter manifold base surfaces.
2. Fill a new filter with clean oil, using the same grade and type of oil as in the sump.
3. Apply clean oil to the filter gasket.
4. Screw on the new filter, after the filter gasket contacts the base tighten one full
turn.
5. After starting the compressor, check for leaks and retighten the filter if necessary.
6. Do not run the compressor with a damaged filter canister. It can fracture or leak.
7. Replace the filter only with an Ariel approved non-bypass type filter.
Oil Filter Element Installation for Cartridge Type Filters
1. For compressors supplied with cartridge type oil filters, remove the filter vessel
drain plug and completely drain the vessel, with the compressor stopped.
2. During draining, remove the flowing vent line and 1/16 in. (2 mm) orifice fitting
and blow out the line with compressed air. Clean the orifice with a 1/32 in.
(1 mm) diameter wire or a standard paper clip (20/21 gage wire). Loosen the nuts
and remove the top cover.
NOTE: REMOVAL OF THE ELEMENT PRIOR TO COMPLETELY DRAINING THE VES-
SEL WILL ALLOW TRAPPED DEBRIS TO ENTER THE OIL HEADER AND CAN
CAUSE SEVERE DAMAGE TO THE COMPRESSOR.
3. After the oil has completely drained, remove the spring plate assembly, strainer
tube and old filter element. Inspect the interior of the vessel and clean it as
required.
4. Visually inspect the interior/exterior of the new element to be sure that it is not
