It is important that gas pressure regulators meet applicable
pressure requirements and that gas meters be rated for the
total amount of appliance Btu being supplied.
Preparation for Operation _____________
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 dryer data label.
• GAS MODELS – check to assure that the dryer is
connected to the type of heat or gas indicated on the
dryer data label.
• The sail switch damper assembly was installed and
adjusted at the factory prior to shipping. However, each
sail switch adjustment must be checked to assure that
this important safety control is functioning.
• Check bolts, nuts, screws, terminals, and fittings for
tightness.
• GAS MODELS – be sure that all gas shutoff valves are in
the open position.
• Be sure all back guard panels and service box covers
have been replaced.
• Check the lint door to assure that it is closed and
secured in place.
• Rotate the tumbler by hand to be sure it moves freely.
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.
Coin Models Only
The display will read “0 minutes” for both tumblers and the
price required to start a cycle.
Insert the proper number of coins into coin acceptor. Once
the correct amount needed to start the dryer has been
inserted, the L.E.D. display will read “SELECT CYCLE.”
Fire Hazard
Test all connections for leaks by brushing on a
soapy water solution (liquid detergent works well).
Never test for leaks with a flame!!!

WARNING
!
Start the dryer by pressing the desired fabric setting. After the
cycle is started, drying time will count down whether the door
is closed or open.
NOTE:
The dryer can be stopped at any time by opening
the main door. To restart dryer, shut the main door and
press desired fabric setting.
Open main door to stop the dryer, and change to a different
fabric setting. Repeat this procedure, until all fabric
selections have been tested. This will also confirm that setting
key circuits and door switch circuits are functioning properly.
Repeat above procedure for the other tumbler.
Heat Circuit Operational Test
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.
Gas dryers are equipped with a DSI system, which has
internal diagnostics. If ignition is not established after the
first attempt, the heat circuit in the DSI module will lockout
until it is manually reset. To reset the DSI system, open
and close the main door and restart the dryer.
Once ignition is established, a gas pressure test should be
taken at the gas valve pressure tap of each dryer to assure
that the water column pressure is correct and consistent.
NOTE:
Water column pressure requirements (measured at
the pressure tap of the gas valve body):
Natural Gas .... 3.5 in wc
L.P. Gas .......... 10.5 in wc
IMPORTANT:
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.
Make a complete operational check of all the operating
controls to ensure that the timing is correct and that the
temperatures are set properly.
Make a complete operational check of all safety related circuits
(i.e., door switches, hi-limit thermostats, sail switches,
tumbler safety thermostats, etc.).
NOTE:
The sail switch can be checked for proper operation
by leaving the control door open and inserting the lint
screen then starting the dryer. The heating unit(s) should
not activate. If the heating unit does activate, make the
necessary adjustments.
Each tumbler should be operated through one complete cycle
to assure that no further adjustments are necessary and that
all components are functioning properly.
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.
