SECTION III
Unscrew the fi lter bowl by turning counter-clockwise. Lower the fi lter bowl to access the
fi lter element contained inside. The fi lter element is held in place with an O-ring and
internal ridges located in the bowl. Replace with DCI Part Number 2006, and reassemble
the
fi lter bowl. Turn the dryer bypass valve to the ON position and check compressor for
proper operation by turning the power switches on.
NOTE: A “popping” relief valve indicates a clogged coalesing element OR
the Dryer Bypass valve is closed.
B. Coalescing Filter Element
The coalescing fi lter element should be checked with the compressor motors running. If
the indicator located on the top of the fi lter housing remains GREEN, the fi lter element has
additional useful life. However, if the indicator turns RED, the element should be changed.
To change the element,
fi rst turn off the compressor motor switches. Then turn off the
Dryer bypass valve as shown in (Fig. E). With dryer bypass valve in OFF position, press the
TEST button on the time operated purge valve to bleed pressure off of the drying system.
Depressurization of the drying system can be con
fi rmed by reading the drying system
pressure gauge located on top of the drying chamber.
WARNING : DO NOT ATTEMPT TO SERVICE WITH SYSTEM PRESSURIZED.

COMPRESSOR MAINTENANCE SCHEDULE
Maintenance Item Frequency
Intake Filter Elements
Every Six Months (semi-annually)
Coalescing Filter Element Every 90 Days
Time Operated Purge Valve Every 60 Days
Tank Drain Every 90 Days
A. Compressor Head Intake Filter Elements
Dirty intake fi lter elements reduce the amount of air the compressor can take in. This
reduces air output and increases the load of the motors. Every six months, remove
the intake
fi lter cover as shown in (Fig. D), to check for excessive dirt or discoloration.
Replace with DCI Part Number 2012 if needed. The fi lters are located on the rear of each
