MAINTENANCE

ture, it is important that ONLY replacement ele-
ments identified with the Sullair name, logo and
appropriate part numbers be used, and that sub-
stitute elements NOT be used, due to the fact that
such filters may have inadequate or questionable
working pressure ratings.
1. Unthread the filter canister from the head. A hex
nut is supplied on the bottom of the canister
along with the bottom portion of the canister has
a rough textured surface. Either can be used to
assist in removal of the canister.
2. Pull the canister away from the filter head. The
filter elements will be attached to the filter head.
3. Separate the element from the filter head.
4. Remove the canister seal.
5. Thoroughly clean the filter head and canister in
solvent.
6. Lubricate the new seals with the same type of
fluid used in the compressor and position each
seal in its appropriate place.
7. Carefully push the element into position under
the housing/head.
8. Replace the canister by threading back onto the
filter head.
AIR FILTER MAINTENANCE
. Air filter maintenance should
be performed when the air filter maintenance mes-
sage is displayed. The air filter is equipped with a
primary and a secondary element. As previously
stated, the Supervisor Controller will alert you as to
when the primary element maintenance is neces-
sary. When removing the primary element, always
check the secondary element for visible dirt,
grease/oil, or damage. The secondary element
must be changed after every sixth primary element
inspection.
DO NOT
clean the secondary element.
AIR FILTER ELEMENT REMOVAL
1. Clean exterior of air filter housing.
2. Remove the cover/element assembly by loosen-
ing the wing nut securing it.
3. Pull the cover/element assembly out of the hous-
ing.
4. On the inside of the element, you will notice a
lock ring, which fastens the cover to the ele-
ment. Remove the lock ring and pull the cover
and element apart.
5. Clean the interior of the housing by using a damp
cloth.
DO NOT
blow dirt with compressed air.
6. Inspect the secondary element and replace if
necessary. This element is
NOT
cleanable.
7. To remove the secondary element, unscrew the
secondary restriction indicator from the threaded
rod running through the element. Pull the ele-
ment out of the housing.
8. Install the new secondary element and replace
the restriction indicator.
