This service, when supplemented by properly
recorded package operational performance and
vibrations trends, is most helpful in identifying the
presence (or absence) of equipment damage which
can be repaired or replaced before a catastrophic
breakdown occurs.
7.9 PARTS REPLACEMENT AND ADJUSTMENT
PROCEDURES
Please, familiarize yourself with the safety guide-
lines offered in Section 1 of this manual before
attempting any maintenance on the package.
7.9.1 AIR FILTER INSPECTION/MAINTENANCE
ELEMENT INSPECTION
1. Place a bright light on one side of each element
to inspect for damage or leak holes.
2. Inspect gaskets and matching sealing surfaces
on the housing. It should be smooth or replace in
case of damage.
3. DO NOT strike elements against a hard surface
to dislodge dirt - this may damage the sealing sur-
faces and/or rupture the element.
AIR FILTER MAINTENANCE
Refer to Figure 7-2 . Air filter maintenance should
be performed at 8000 hours, one year or when the
corresponding maintenance message is displayed
by the controller. This corresponds to a pressure
loss condition across the filter of 12 in. (30.5 cm) of
water. Your filter assembly includes a pre-filter ele-
ment and a main element.
1. Loosen screws and remove access panel.
2. Remove the pre-filter and main filter elements.

Refer to Figure 7-3 . Oil filter maintenance (using
repair kit P/N 02250049-820) should be performed
at 8,000 hours, one year or when the corresponding
maintenance message is displayed by the con-
troller - this corresponds to a pressure loss condi-
tion across the unit of 20 psi (1.4 barg). Your oil fil-
ter includes a proprietary replaceable element (P/N
02250049-821) available solely from Sullair and its
