MAINTENANCE REQUIREMENTS
The frequency of your maintenance requirements depends upon the number of
hours of operation and upon variances in your product output. For a single-shift
operation, without special problems, the frequency recommended below should
suffice. You should set your own schedule based on your experience.
1. WEEKLY
Visually inspect the filter inside and outside, its controls and their operation.
At time of such inspection, note and correct any discrepancies from normal
operation.
2. MONTHLY
Check the static pressure. Use a magnehelic gauge, manometer, or U-tube to
measure and record the resistance. This will show the pattern of operation of
your system. If pressure exceeds 1 inch W.C., insure the rotor is correctly
turning and cleaning the screen.
Watch the air pressure gauge on the filter. Record the drop in pressure
during the blow down cycle. A normal pressure is from 100psi at the start to
80psi after six seconds. The minimum pressure is 80psi. Any less will not
reliably clean the screen. If the pressure were to fall from 100psi to 40psi, the
air supply is inadequate or obstructed.
3. QUARTERLY
Test the Fenwall fire sensor accessed through the inspection door. Heat the
Fenwell fire sensor with a heat lamp or other convenient source. When the
audible/visual indicators actuate as well as the water solenoid remove heat
source and allow Fenwell fire sensor to cool. The fire suppression system will
reset after 60 seconds.
FILTER SCREEN MAINTENANCE
Chemicals present in the laundry uniforms, shop towels or other linen may
eventually clog the filter screen. When this occurs, try the following:
1. Spray with an engine degreaser like GUNK. Allow soaking per the
instructions for cleaning an auto engine. Spray clean with water.
2. Operate one dryer without a load to blow hot air through the filter to dry it.
Restart the dryer. Operation should be perfectly normal. It should not be
necessary to replace the screen unless it is punctured.
