5.Heat Circuit Operational Test a. Gas Models

1)When the dryer is first started (during initial start-up), the burners have a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air, so the dryer may have to be stopped and restarted several times for this air to be purged from the lines.

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 system will retry two (2) more times. If ignition is not established after three (3) attempts, the heat circuit DSI module will lockout until it is manually reset. To reset the DSI system, open and close main doors and restart dryer (press "ENTER/START" key).

NOTE: During the purging period, verify that ALL gas shut-off 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 pressure is correct and consistent.

NOTE: Water column (W.C.) pressure requirements (measured at both gas valve pressure taps)...

NATURAL GAS -------------

3.5 INCHES W.C. (8.7 mb).

L.P. GAS ----------------------

10.5 INCHES W.C. (26.1 mb).

IMPORTANT: There is no regulator provided in an L.P. dryer. The water column (W.C.) pressure must be regulated at the source (L.P. tank), or an external regulator must be added to each dryer.

b.Steam Models

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

6.Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch and sail switches on Gas Models).

7.A reversing tumbler (basket) should never be operated with less than a 50 pound (22 kg) load (dry weight). The size of the load will affect the coast-down and dwell (stop) times. The tumbler must come to a complete stop before starting in the opposite direction. For automatic (mode) cycle only, the spin and stop times are not adjustable and have been preprogrammed into the microprocessor controller (computer) for a 2 minute spin time and a 5-second dwell (stop) time.

BASKET COATING

The tumbler (basket) is treated with a protective coating. We suggest dampening old garments or cloth material with a solution of water and non-flammable mild detergent and tumbling them in the tumbler (basket) to remove this coating.
