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.

NOTE:

!During the purging period, check to be sure that ALL gas shutoff valves are open.

Gas model dryers are equipped with an ignition system, which has internal diagnostics. If ignition is not established after one (1) time, the heat circuit in the ignition module will attempt two (2) more ignitions (total of three [3] ignition attempts). If there is no flame after the third ignition attempt the module will lock out until it is manually reset. To reset the ignition system, open and close the main door and restart the dryer.

A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column (W.C.) pressure is correct and consistent.

NOTE:

!Water column 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 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 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 door while heating circuit (gas burner/electric oven) is active (on). The heating unit should shut off within a few seconds. If not, make 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 (TUMBLER) 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 dryer, open main door or pressing 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.
