3) Start the dryer by pressing the desired setting (i.e., “LO” [low] selection for upper basket [tumbler]).
The light emitting diode (L.E.D.) display(s) will now read the selection (setting) made and the
amount of time vended (i.e., “LO 10”).
NOTE: The dryer can be stopped at any time by opening the main door. To restart dryer, shut the
main door and press the desired setting.
4) Open the main door to stop the dryer, and change selection to “PERM PRESS” setting. Repeat this
procedure, but change the selection (setting) to “HI” (high). This will also confirm that setting key
circuits and door switch circuits are functioning properly.
5) Repeat above procedure for the other basket (tumbler).
b. OPL (Non-Coin) Models Only
1) The L.E.D. display(s) will read “FILL” meaning that the dryer is available.
2) Start the dryer by pressing the “E” on the keypad. The L.E.D. display will quickly show “Ld 30,”
“LC 04,” and “F 180.” The dryer will start and the L.E.D. display will show “dr 30.”
NOTE: The dryer can be stopped at any time by opening the main door. To restart dryer, shut the
main door and press “ENTER/START.”
3) Repeat above procedure for the other basket (tumbler).
2. Heat Circuit Operational Test
a. When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition
attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air
to be purged from the lines.
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
NOTE: Gas dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal
diagnostics. If ignition is not established after the first attempt, the heat circuit in 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.
b. Once ignition is established, a gas pressure test 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.
NOTE: Water column pressure requirements (measured at the pressure tap of the gas valve body):
Natural Gas ---------------------- 3.5 inches (8.7 mb) water column.
Liquid Propane (L.P.) Gas ----- 10.5 inches (26.1 mb) water column.
IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank) or an external regulator must be added to each
dryer.
