Also clean the sintered element in the small oil filter supplied on the force feed lubrication system on the same schedule or every time main oil filter is changed.

Or every six months, or 4000 hours, whichever comes first. 2. On start-up differential pressure may exceed the tabled limits until the oil reaches operating temperature. 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 <strong>Ariel</strong> 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 7/09 PAGE 4 - 53

Insert the strainer tube and install the spring plate assembly. 7. Inspect the top cover O-ring and replace if damaged. Install the cover and tighten hold down nuts to 70-80 lb-ft (95-110 N·m) torque. 8. Install the flowing vent line and orifice, and tighten the fittings. 9. Install and tighten the filter vessel drain plug. Fill the vessel with oil, using the prelube system. Check the oil pressure gauges to be sure the vessel is full. NOTE: FAILURE TO FILL THE FILTER VESSEL WITH OIL PRIOR TO STARTING, CAN CAUSE SEVERE DAMAGE TO THE COMPRESSOR. 10. After starting the compressor, check for oil leaks. Fix any leaks. 11. Replace the filter element only with an <strong>Ariel</strong> approved type element.
