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. Installer must instruct the
user on how to correctly operate the dryer before leaving.
Turn on electric power to the dryer.
Refer to the Operating Instructions for starting your particular
model dryer.

Gas Dryers

Open all shutoff valves.
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.
A gas pressure test should be taken at the gas valve pressure
tap of each dryer to ensure that the water column pressure is
correct and consistent.
NOTE: Water column pressure requirements (measured at
the pressure tap of the gas valve body) must be verified.
IMPORTANT: In most cases 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.
Electrical Dryers
Check to ensure that electric oven/contactor assembly is
activating.
Safety Related Circuits
Make a complete operational check of all safety related
circuits:
• Door Switch(es)
• Hi-Limit Thermostats
Make a complete operational check of all operating controls.
Tumbler Coating
The tumbler is treated with a protective coating. We suggest
dampening old garments or cloth material with a solution of
water and nonflammable mild detergent and tumbling them
in the tumbler to remove this coating.
Microprocessor Programs/Selections
Each microprocessor controller (computer) has been
preprogrammed by the factory with the most commonly used
parameter (program) selections. If computer program
changes are required, refer to the computer programming
manual, which was shipped with the dryer.

Preoperational Instructions __________

IMPORTANT: For more detailed information regarding the
microprocessor controller (computer), refer to the
microprocessor user's manual included with the dryer.
Coin Models
Microprocessor Controller (Computer)
When the microprocessor controller (computer) is in the ready
state, the L.C.D. screen will display "FILL" and (XX.XX)
Amount.
Insert coin(s). Once the correct "Amount to Start" has been
inserted, the L.C.D. will display "PUSH".
Select temperature by pressing "HI," "LO," or "PERM PRESS."
The cycle will start and the L.C.D. will display the temperature
cycle selected and the remaining time.
The dryer will continue through the drying and cooling cycles,
until the vended time has expired.
NOTE: To stop the dryer, open main door. Continuation of
the cycle will resume only after the door has been closed
and any one of the three temperature selections is
pressed.
Non-Coin Models
Microprocessor Controller (Computer)
The L.E.D. display reads "FILL" (no cycle in progress).
Select temperature by pressing "HI," "LO," or "PERM PRESS."
The dryer will then start (i.e. blower, tumbler, and heat).
The L.E.D. will display the temperature cycle selected and
the remaining time.
NOTE: The dryer can be stopped at any time by opening
the main door or the lint door.
When the programmed drying time has expired, the non-
coin microprocessor controller (computer) will proceed into
the Cool Down Cycle.

Shutdown Instructions _______________

If the dryer is to be shutdown (taken out of service) for a
period of time, the following must be performed:
Discontinue power to the dryer either at the external
disconnect switch or the circuit breaker.
Discontinue the heat supply:
Gas Models – Discontinue the gas supply.
Shut off external gas supply shutoff valve.
Shut off internal gas supply shutoff valve located in the gas
valve burner area.
