6.5.2.2 Air Filter Element Cleaning - Continued
When cleaning an element, never exceed the maximum allowable pressures for
compressed air (30 psi).
Do not strike the element against any hard surface to dislodge dust. This will damage the
sealing surfaces and possibly rupture the element. Never "blow" dirt out of the interior of
the filter housing. This may introduce dust downstream of the filter. Instead, use a clean
damp cloth. Do not oil the elements.
6.5.2.3 Cleaning the Air Filter Element with Compressed Air
When cleaning the element with compressed air, never let the air pressure exceed 30 PSI.
Reverse flush the element by directing the compressed air up and down the pleats in the
filter media from the "clean side" of the element. Continue reverse flushing until all dust
is removed. Should any oil or greasy dirt remain on the filter surface the element should
then be replaced. When the element is satisfactorily cleaned, inspect thoroughly prior to
installation (See 6.5.2.4, Air Filter Element Inspection).
6.5.2.4 Air Filter Element Inspection
1. Place a bright light inside the element to inspect for damage or leak holes.
Concentrated light will shine through the element and disclose any holes.
2. Inspect all gaskets and gasket contact surfaces of the housing. Should faulty gaskets
be evident, correct the condition immediately.
3. If the clean element is to be stored for later use, it must be stored in a clean container.
4. After the element has been installed, inspect and tighten, if necessary, all air inlet
connections prior to resuming operation.
6.5.3 Separation Element Replacement
Refer to Figure 6-4. When fluid carry-over is evident after the fluid return line orifice as
well as the blowdown valve diaphragm have been inspected and found to be in
satisfactory condition, separator element replacement (P/N 260017-001) is necessary.
Follow the procedure explained below.
1. Remove all piping connected to the sump cover to allow removal (return line, service
line, etc.).
2. Remove the fluid return line from the fitting in the cover.
3. Remove the eight (8) ½- 13 cover bolts and lock washers and lift the cover from the
sump.
