Maintenance
Note: Maintenance must be performed by an authorized service technician.
Never attempt to adjust the temperature; this
adjustment should only be done by an autho-
rized service technician.
1. See FIGURE 5. Periodically clean the
Condenser (#11). Use a dust collector and
an air gun to clean dirt and debris. Be careful
not to get too close to the unit with high
pressure as you will damage the unit. If
grease or oil are built up and won’t blow off,
wash it off with a mild detergent.
Note: The internal parts illustrated for step 2 below
are a guide for the authorized service
technician. They cannot be ordered
separately. Only the parts on the parts list
on page 9 can be ordered.
2. See FIGURE 6. Washing the auto drain. To
wash the auto drain, close the 1/2 ball Filter
Valve on top of the drain. Pull the manual
drain shaft handle to empty the water. Take
apart the drain and the fixed screw. Clean
the strainer from inside to out. Take apart
the manual drain shaft and the seal end cap.
Take off the float ball and valve seat. Clean
each component and reassemble.

Problem 7: Ice accumulating in the dryer, and/or a pressure loss through the unit.
Reason: This may be caused by the formation of ice inside.
Solution: The Hot Gas Bypass Valve (not shown in the Parts List or Assembly Diagram) needs to be
adjusted. This adjustment should only be done after consultation with our technical support
service at: 1-800-444-3353.
