If system is fitted with a pre-filter, it should be checked regularly to ensure that the element is in
good condition. If element appears to be dirty or begins to cause flow restriction in system, it
should be replaced.
Filter Element Replacement
(Refer to Figure 9)
1.
Loosen bolt on bottom of filter.
2.
Gently pull apart assembly and remove old element.
3.
Place new element into grooves in top and bottom of housing.
4.
When re-assembling, inspect for o-rings on top and bottom caps and on center bolt.
5.
Install glass shell onto bottom piece.
6.
Place new element in groove in bottom piece. Be sure that element is seated correctly and
parallel to glass shell.
7.
Carefully mate bottom assembly onto top piece. Slight twisting motion may be required to
allow shell to slip over o-ring seal.
8.
Visually make sure element is seated correctly in top groove.
9.
Replace bolt through hole in bottom piece and screw clockwise into top piece. Do not
over-tighten center bolt. It should be just tight enough so it does not vibrate loose.
Over-tightening will not help the filter to seal.
