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.
