DRY TYPE INLET FILTER
2500 Hours - Maintenance
The inlet fi lter on the scroll compressor assures 99%
particulate free air is admitted to the unit. Change every
2,500 hours or more often in dirty locations.
1. Remove fi lter cover.
Do not attempt to clean fi lter. This fi lter
requires replacement and is to be replaced
when contaminated.
2. Install new fi lter element and reassemble cover.
CLEAN COMPRESSOR FINS
2500 Hours - Maintenance
1. Remove the FS cover (see page 6).
2. Clean compressor fi ns using compressed air.
3. Put the FS cover back.
GREASE COMPRESSOR BEARINGS
10,000 Hours - Maintenance
Per OSHA regulations, ALL power must
be locked out before performing any
maintenance.
This service should be performed by an
authorized Powerex Service Center to
avoid failure.
OS Bearing
1. Remove the plastic dust cap (See Figure 1).
2. Rotate the compressor pulley until the grease fi tting is
visible through the dust cap hole (See Figure 1). This will
allow regreasing of the OS bearing.
3. Use a grease gun extension adaptor to engage the
grease fi tting and supply the proper volume of grease
as indicated on the grease delivery chart (See Grease
Delivery chart on Page 2 and on Figure 1).
Use only Powerex genuine grease. Pump
grease gun before feeding. This eliminates
air from the grease passage of the extension adapter.
4. Replace plastic dust cap.
Greasing Pin Crank Bearings
The bearings on the scroll compressor are regreaseable to
allow extended compressor life. Service should be performed
according to the Maintenance Schedule on Page 2.
1. Remove the fan duct (2), part number 5 on Pages 6 and 7.
2. Remove the nuts and bolts and then the fi xed scroll (FS)
from the air end.
3. Grease all three pin crank bearings (See Figure 2 below
and Grease Delivery Chart on page 2).
4. Replace the fi xed scroll and fan duct (2). See the Bolt
Torques chart on page 5.
