Warning
Electrical power must be provided to the dryer
at all times. If the main electrical power supply
to the dryer is disconnected, the fire suppression
system is inoperative!!
Preparation for Operation/Start-Up __
The following items should be checked before attempting to
operate the dryer:
• Read all “CAUTION,” “WARNING,” and “DIRECTION”
labels attached to the dryer.
• Check incoming supply voltage to be sure that it is the
same as indicated on the data label. In the case of 208
VAC or 240 VAC, the supply voltage must match the
electric service exactly.
• GAS MODELS – Check to ensure that the dryer is
connected to the type of heat/gas indicated on the dryer
data label.
• GAS MODELS – Be sure that all gas shutoff valves are
in the open position.
• Be sure all back panels (guards) and electric box covers
are in place.
• Be sure the service doors are closed and securely in
place.
• Be sure the lint door/drawer is securely in place.
• Rotate the tumbler (drum) by hand to be sure it moves
freely.
• Check bolts, nuts, screws, terminals, and fittings for
tightness and security.
• Check that the vent is connected to the dryer and is
exhausted to the outdoors.
• STEAM MODELS – Check to ensure all steam shutoff
valves are open.
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.
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
• Sail Switch
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 “Ready, Insert $XX.XX
(amount) to Start”.
Insert coin(s). Once the correct “Amount to Start” has been
inserted, the L.C.D. will display “Select Temperature”.
Select temperature by pressing “HI,” “MED,” or “LO.” The
cycle will start and the L.C.D. will display the Dry 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 3 temperature selections is pressed.
