Do not oil this element. Do not wash in inflammable cleaning fluids. Do not use
solvents other than water. Improper cleaning may damage the element.
NOTICE
Never operate the unit without the element. Never use elements that are
damaged, ruptured or wet. Never use gaskets that won't seal. Keep spare
elements and gaskets on hand to reduce downtime. Store elements in a
protected area free from damage, dirt and moisture. Handle all parts with care.
Filter Element Life - The element should be replaced after six (6) cleanings or if:
1. Visual inspection indicates a rupture, crack or pin hole in the pleated media. Inspection should be
done by placing a bright light inside the element.
2.
Pressure drop through a filter with a freshly cleaned element is below three (3) inches (76 mm) of
water with the compressor running at full load - this would indicate a rupture or crack.
Inlet Tube - Inspect the inlet screen and tube for dirt accumulation each time the filter is serviced. Clean
the tube when required by ramming a clean dry cloth through the tube. Wipe the inside of the filter body
to remove any dirt falling from the inlet tube before reinstalling the element.
Causes of short element life include: severe dust conditions, infrequent servicing, improper cleaning, or
contamination by oil or chemical fumes.
Package Air Inlet Filter – ( Figure 1-2, page 10) The package is supplied with cooling air intake filters
shown in Figure 1-2, Page 10. These filters should be inspected every 1,000 hours. If dirty they should
be cleaned or replaced. The filters should not be cleaned more than 6 times.
Clean Filters –
1. Remove Filters from base.
2. Clean Filters with running water.
3. Let dry.
