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.

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.

Non-Coin Models

Microprocessor Controller (Computer)

The L.E.D. display reads “READY” (no cycle in progress).
Press the letter on the keypad corresponding to the cycle
desired (e.g. key “D”).
The dryer will then start (i.e. blower, tumbler, and heat).
The L.E.D. display will read MANUAL DRYING CYCLE D,
___MIN REMAIN.

Note

The dryer can be stopped at any time by pressing
the “STOP/CLEAR” 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 “READY” 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.E.D. display will read COOL DOWN TEMP __/__
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.

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.

Service/Parts Information ____________

Service

Service must be performed by a qualified trained technician,
service agency, or gas supplier.  If service is required, contact
the Maytag distributor from whom the equipment was
purchased.  If the distributor cannot be contacted or is
unknown, contact the Maytag Co. for a distributor in your area.

Note

When contacting the Maytag Co., be sure to give
them the correct model number and serial number

so that your inquiry is handled in an expeditious manner.

Parts

Replacement parts should be purchased from the distributor
from whom the Maytag equipment was purchased. If the
distributor cannot be contacted or is unknown, contact the
Maytag Co. for a distributor in your area.
