2)The dryer is equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If ignition is not established after the first attempt, the heat circuit DSI module will “LOCKOUT” until it is manually reset. To reset the DSI system, open and close main door and restart dryer (press the “ENTER/START” key).

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

3)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 (W.C.) pressure is correct and consistent.

NOTE: Water column pressure requirements (measured at the gas valve pressure tap)...

Natural Gas --------------------- 3.5 inches (8.7 mb) water column.

Liquid Propane (L.P.) Gas ---- 10.5 inches (26.1 mb) water column.

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.

b.Electric Models

1)Check the oven contactors to insure that the electric oven is cycling properly.

c.Steam Models

1)Check to insure that the steam damper is functioning properly.

a)The steam damper should not “slam” (open/closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind or stop during travel. If either of these conditions occur, the flow control must be adjusted. Refer to the Cool Down Mode in the top illustration on page 37 for air adjustment instructions.

6.Make a complete operational check of ALL safety related circuits (i.e., lint drawer switch and sail switch on gas models).

NOTE: To check for proper sail switch operation, open the main door and while holding main door switch plunger in, start dryer. Dryer should start but heat circuit should not be activated (on). If heat (burner) does activate, shut the dryer off and make the necessary adjustments.

7.A reversing basket (tumbler) dryer should never be operated with less than a 75 lb (34 kg) load (dry weight). The size of the load will affect the coast-down and dwell (stop) times. The basket (tumbler) must come to a complete stop before starting in the opposite direction.

a. Microprocessor Controller (Computer) Dryers

1)Spin and dwell (stop) times are not adjustable in the Automatic Mode and have been preprogrammed into the microprocessor controller (computer) for 120-seconds spin time and a 5-second dwell (stop) time.

2)Spin and dwell (stop) times are adjustable in the Manual (timed) Mode.
