b) The regulator will maintain a nearly constant outlet air pressure of 80 psi (5.51 bar) so that the
dryer’s air pistons will function normally despite upstream air pressure variation.
J. PREOPERATIONAL TEST
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. Turn on electric power to the dryer.
2. Make sure the loading doors are closed and the lint drawer is closed.
3. Press in “green” power button and it will illuminate.
4. Microprocessor controller (computer) system operational test to start the dryer:
a. Display will read “READY.”
b. Press “D” (preprogrammed) cycle key on the keypad.
5. The dryer will then start (i.e., blower, basket [tumbler], and heat).
6. The light emitting diode (L.E.D.) display will read MANUAL DRYING CYCLE D, 00:00 MIN REMAIN.
NOTE: Press the “UP ARROW” to view the basket (tumbler) temperature at any time.
NOTE: The dryer can be stopped at any time by pressing the “STOP/CLEAR” key. If the
temperature is above the Cool Down set point when the “STOP/CLEAR” is pressed, the
dryer will go into a Cool Down Cycle. If the “STOP/CLEAR” key is pressed again at this
point the cycle that was in progress will be canceled and returned to the “READY” state. If
the temperature is below the Cool Down set point, the cycle that was in progress will be
canceled and go into Wrinkle Guard Cycle.
7. When the programmed drying time has expired, the Phase 7 non-coin microprocessor controller (computer)
will proceed into the Cool Down Cycle (mode).
8. Once the Cool Down Cycle begins at the end of the heat cycle the L.E.D. display will read COOL DOWN
TEMP ___/___ MINUTE REMAINING. At the end of the heat cycle, the dryer will shut off the heat and
continue the fan and basket (tumbler) until the Cool Down time, or temperature is reached.
9. Once the Cool Down Cycle is completed, the Phase 7 non-coin microprocessor controller (computer) will
proceed into the Wrinkle Guard Cycle. The Audio Alert tone will sound for the amount of time set in Audio
Alert ON Time. The L.E.D. display will read “WRINKLE GUARD.” The times are fixed at 2 minutes
OFF, 2 minutes ON for a maximum time of 99 minutes. These times are not programmable. During the
ON time, the blower (fan) and the basket (tumbler) will start to rotate (without heat for 2 minutes). The
Phase 7 non-coin microprocessor controller (computer) will repeat this process until the Maximum Wrinkle
Guard On Time has expired (99 minutes). The L.E.D. display will then read “CYCLE DONE” and lockout
the dryer functions until the doors are opened. It will then return to “READY.”
