cuts or pinches to the gasket.
5. Continue tightening element by hand an addi-
tional 1/2 to 3/4 turn.
6. Restart compressor and check for leaks.
To minimize the possibility of filter element rup-
ture, it is important that ONLY replacement ele-
ments identified with the Sullair name, logo and
appropriate part number be used and that substi-
tuted elements not be used, due to the fact that
such filters may have inadequate or questionable
working pressure ratings.
AIR FILTER MAINTENANCE
Refer to Figure 7-2. Air filter maintenance should be
performed when the maintenance gauge shows red
with the compressor running full load, or once a
year, whichever comes first. If the filter needs to be
replaced, order replacement elements. Below you
will find procedures on how to replace the air filter
elements.
AIR FILTER ELEMENT REPLACEMENT
1. Clean exterior of air filter housing.
2. Pull yellow latch to release end cover.
3. Rotate end-cover counterclockwise and remove.
4. Remove element and clean interior of housing
using a damp cloth. DO NOT blow dirt out with
compressed air.
5. At this time replace the element.
6. Reassemble in the reverse order of the disas-
sembly.
7. Reset the air filter restriction indicator if equipped
(Electro-mechanical models only.)
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 all air inlet connections prior to resuming
operation.
