Preoperational Tests ________________
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 Models Only
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.
The dryer is equipped with a Direct Spark Ignition (DSI)
system, the DSI control module has internal diagnostics. If
ignition is not established within three (3) attempts, the heat
circuit in the DSI control module will “LOCK OUT” until
manually reset. To reset the DSI system, open and close the
main door and restart the dryer.
Note
Water column (W.C.) pressure requirements
(measured at the pressure tap of the gas valve
body):
Natural Gas ______________ 3.5 Inches (8.7 mb) W.C.
Liquid Propane (L.P.) Gas ___ 10.5 Inches (26.1 mb) W.C.
Important
There is no regulator provided in a liquid propane
(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.
Make a complete operational check of all safety related
circuits:
• Door Switch(es)
• Hi-Limit Thermostats
• Cycling Thermostat
Gas and Electric Models Only – Sail Switch
Note
The sail switch can be checked for proper
operation by opening the lint drawer. While
pushing the lint drawer switch in, start a drying cycle. The
heating unit should not activate (wait 30-seconds). If heat
does activate, make the necessary adjustments to the sail
switch.
Make a complete operational check of all operating controls.
Note
If computer program changes are required, refer
to the computer programming section of the
manual supplied with the dryer.
The dryer should be operated through one (1) complete cycle
to ensure that no further adjustments are necessary and that
all components are functioning properly.
Basket Coating
The basket (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 basket (tumbler) to remove this coating.
Check the electric service phase sequence (3-phase [3ø]
models only). While the dryer is operating, check to see if the
blower wheel (impellor/fan) is rotating in the proper direction.
Looking from the front, the blower wheel (impellor/fan) should
spin in the clockwise (CW) direction. If it is, the phasing is
correct. If the phasing is incorrect, reverse two (2) of the three
(3) leads at connections L1, L2, and L3 of the power supply
to the dryer.
Important
If the blower wheel (impellor/fan) is rotating in the
wrong direction, this will not only drastically
reduce drying efficiency, but it can also cause premature
component failure.
Preoperational Instructions _________
Coin Models
Microprocessor Controller (Computer)
When the microprocessor controller (computer) is in the ready
state, the liquid crystal display (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 or press the
pause key. Continuation of the cycle will resume
only after the door has been closed and any of the three (3)
temperature selection is pressed.
Upon completion of the drying and cooling cycles, the tone
(buzzer) will sound and the dryer will go into the Anti-Wrinkle
Mode for 99 minutes, or until the main door has been opened.
Important
For more detailed information regarding the
microprocessor controller (computer) on your
dryer, refer to the microprocessor user’s manual included
with the dryer.
Mechanical Drop/Rotary Coin Meter
or Slide Coin Meter
,
Insert coin and turn knob (rotary type meter), or for slide meter
unit, push in coin chute.
Select temperature.
Push the “Start” button.
To stop the dryer, open the main door.
