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 vacuum 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 machine 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 down the tube, they can also simultaneously
flush out the tubes with water. There is a wide variety of brushes and tools available that attach to the shaft
to clean both soft and hard deposits.
Drain Line Y-Strainer (See Figure 3 in Section G for detail)
The drain line y-strainer should be cleaned weekly. Air flow and air pressure should be removed from
system before proceeding. To clean the y-strainer:

Turn the ball valve on the strainer assembly to the closed position

Remove threaded cap at the end of the ball valve assembly.

Clean the screen inside of the cap by rinsing it under water.

Reinstall the screen and cap

Return the ball valve to the open position
High Pressure, Low Pressure, & Fan Control (AC units only)
The refrigeration pressure switches should be checked monthly to ensure that they are adjusted to the
proper settings. Please refer to the applicable electrical drawings for your unit.
