L. PREOPERATIONAL INSTRUCTIONS
IMPORTANT: For more detailed information regarding the microprocessor controller (computer), refer to the
microprocessor user’s manual included with the dryer.
1. Microprocessor Controller (Computer)
The light emitting diode (L.E.D.) display reads “READY” (no cycle in progress).
Press the letter on the keypad corresponding to the cycle desired (i.e., key “D”).
The dryer will then start (i.e., blower, tumbler, and heat).
The L.E.D. display will read MANUAL DRYING CYCLE D, 00:00 MIN REMAIN.
NOTE: The dryer can be stopped at any time by pressing the “STOP/CLEAR” key, at this time the dryer will
go into a cycle pause. If the “STOP/CLEAR” key is pressed again at this point, the cycle that was in
progress will be cancelled and returned to the “READY” state.
When the programmed drying time has expired, the Phase 7 non-coin microprocessor controller (computer) will
proceed into the Cool Down Cycle.
Once the Cool Down Cycle begins at the end of the heat cycle, the L.E.D. display will read COOL DOWN TEMP
___/___ MINUTES remaining. At the end of the heat cycle, the dryer will shut off the heat and continue the fan
and tumbler until the Cool Down Time or temperature is reached.
2. Mechanical Timer
Turn drying timer knob for a time of 20 minutes.
Select “High Temp.”
Push “Push to Start” button.
To stop the dryer, open the main door.
M. COMPRESSED AIR REQUIREMENTS
The dryer requires an external supply of compressed air (4.25 cfh @ 80 psi [0.12 cmh @ 5.51 bar]). For steam models,
compressed air is necessary for the air-operated steam damper. On both the steam models as well as the gas models,
compressed air is necessary/required for blower air jet operation to clean lint from the impellor/fan (squirrel cage).
