Routine Maintenance
This section covers the various components that require periodic maintenance
and/or replacement.
Coalescing Filter Element
The coalescing filter element should be check Bi-Annually. On units with the standard
control panel, check the pressure drop across the unit by using air pressure gauges
upstream and downstream of the dryer using the closest possible gauges to the dryer. If
it is determined that there is a high pressure drop across the machine, remove the filter
element from the machine and inspect it. If the filter is dirty, replace it. Ensure that air
pressure is removed from the machine prior to removing the filter element. On units that
have the Control Center option installed the filter differential can be checked on the control
board.
The coalescing element should be changed annually. To change the filter element:
•
De-pressurize the dryer.
•
Remove the bolts that secure the filter housing cover.
•
Remove the wing nut that secures the filter cap to the element.
•
Remove the filter cap.
•
Remove the existing element from the housing.
•
Install the replacement element.
•
Reinstall the filter cap and wing nut
•
Reinstall the filter cover.
Condensing Coil (Air Cooled Units)
The condensing coil should be cleaned weekly. Ensure that air pressure is removed from
the system prior to cleaning the condenser. The condenser can be cleaned by using a vac-
uum or compressed air. If the condenser is not clean after it is blown out with compressed
air or vacuumed, contact the factory for assistance.
Condenser (Water Cooled Units)
The water cooled condenser should be checked and cleaned annually if necessary. To
check the condenser, water flow to the condenser should be shut off, air flow to the ma-
chine should be shut off, and the unit should be taken out of a run mode. The end bonnets
then need to be removed exposing the tube side of the condenser. The tube side should be
inspected for any debris and cleaned. If soft deposits are found they can be cleaned using
a pneumatic tube cleaning gun which forces plugs down the tubes. Some have a brush
between two rubber plugs and others are specially designed plugs which scrape the tube
walls as they travel down the tube. If scale is found special equipment is required to clean
the tubes. These cleaning systems utilize a flexible shaft which rotates a brush as it is fed
