NOTE: The dryer can be stopped at any time by opening the main door. To restart the dryer, shut the
main door and press the desired setting.
4) Open main door to stop the dryer, and change selection to “PERM PRESS” (medium) setting.
Repeat this procedure, but change the selection (setting) to “HIGH TEMP.” This will confirm that
the selection key circuits are functioning properly.
NOTE: Selection (setting) changes can be made at any time during the drying cycle by opening and
closing the main door and then making a new selection.
5) Repeat above procedure for other basket (tumbler).
b. OPL (NON-COIN) MODELS ONLY
1) The light emitting diode (L.E.D.) display(s) will read “FILL,” which means that the dryer is available.
2) Start the dryer by pressing the desired setting “LOW TEMP.” The L.E.D. display will now read
selection (setting) made and the drying time portion of the L.E.D. display will read “00” and count
upwards in time.
NOTE: The dryer can be stopped at any time by opening the main door. To restart the dryer, shut the
main door and press the desired setting.
3) Open main door to stop the dryer, and change selection to “PERM PRESS” (medium) setting.
Repeat this procedure, but change the selection (setting) to “HIGH TEMP.” This will confirm
that the selection key circuits and door switch circuits are functioning properly.
NOTE: Selection (setting) changes can be made at any time during the drying cycle by opening and
closing the main door and then making a new selection.
4) Repeat above procedure for the other basket (tumbler).
3. Heat Circuit Operational Test
a. GAS MODELS
When a gas dryer is first started (during the initial start-up), it has a tendency not to ignite on the first
attempt. This is because the gas supply piping is filled with air. It may take a few minutes for this air
to be purged from the lines.
The dryer is equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If
ignition is not established after the first attempt, the heat circuit DSI module will try two (2) additional
times and if a flame is not established, the DSI module will lockout until it is manually reset. To reset the
DSI system, open and close the main door and restart the dryer (press desired temperature selection).
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
Once ignition is established, a gas pressure reading should be taken at the gas valve pressure tap of
each dryer to assure that the water column (W.C.) pressure is correct and consistent.
