7. Install the new secondary element and replace
the sealing washer and hex nut.
8. With the secondary element in place, replace the
primary element.
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 evi-
dent, 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 all air inlet connections prior to resuming
operation.
PRIMARY ELEMENT REPLACEMENT
1. Place the element in position over secondary
element. Replace the sealing washer and
wingnut. Tighten the wingnut so as to fully seat
the element gasket.
2. Install the cover/element assembly and replace
the wingnut.
