Preparation for Operation/Start-Up ___

The following items should be checked before attempting to
operate the dryer:

• Read all “WARNING” and “DIRECTION” labels attached

to the dryer.

• Check incoming supply voltage to ensure that it is the

same as indicated on the data label.

• Ensure that all gas shutoff valves are in the open

position.

• Ensure all back panels (guards) and electric box covers

are in place.

• Ensure the service doors are closed and securely in

place.

• Ensure the lint door/drawer is securely in place.

• Rotate the tumbler (drum) by hand to ensure 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.

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 dryer.

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 ensure that all

gas shutoff valves are open.

Tumbler Coating

The  tumbler  is  treated  with  an  oil  coating.   To  remove  this
coating,  dampen  a  good  amount  of  old  garments  or  cloth
material  with  a  solution  of  water  and  nonflammable  mild
detergent  and  tumble  them  in  the  tumbler  without  heat  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.

Operating Instructions ________________

Once the load has been put into the dryer and the main door
is closed, start the dryer as follows:

The  L.C.D.  display  reads  “SELECT  CYCLE”  (no  cycle  in
progress).

Scroll  up  or  down  to  the  desired  cycle  using  the  HIGH  or
LOW key.  Press MED.

The dryer will then start (i.e. blower, tumbler, and heat).

The L.C.D. display will read the name of the selected cycle
and approximate remaining minutes.

NOTE: 

The dryer can be stopped at any time by pressing

the “PAUSE” key, at this time the dryer will go into a cycle
pause.  If the “STOP/CLEAR” key is pressed again at this
point, the cycle that was in progress will be cancelled and
returned to the “SELECT CYCLE” state.

When  the  programmed  drying  time  has  expired,  the  non-
coin microprocessor controller (computer) will proceed into
the Cool Down Cycle.

Once  the  Cool  Down  Cycle  begins  at  the  end  of  the  heat
cycle,  the  L.C.D.  display  will  read  “COOL  DOWN”
__/__ MINUTES remaining.  At the end of the heat cycle, the
dryer will shut off the heat and continue the fan and tumbler
until the Cool Down Time or temperature is reached.

The  dryer  tumbler  can  be  stopped  at  any  time  by  opening
the main door.  To restart dryer, shut the main door and press
desired setting.
