J. PREOPERATIONAL TEST

ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions.

1.Turn on electric power to the dryer.

2.Make sure the main door is closed and the lint drawer is securely in place.

3.Refer to the Operating Instructions for starting your particular model dryer.

4.Check to ensure that the basket (tumbler) starts in the clockwise (CW) direction. Additionally, check the direction of the blower motor impellor (fan) to ensure that the blower motor impellor (fan) rotates in the clockwise (CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.

IMPORTANT: Dryer blower motor/pulley that drives the impellor/fan (squirrel cage) when viewed from the back of the dryer must turn in the counterclockwise (CCW) direction, otherwise the dryer efficiency will be drastically reduced and premature component failure can result.

5.Heat Circuit Operational Test a. Gas Models

1)When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the first attempt. This is because the gas supply piping is filled with air, so it may take a few minutes 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 three (3) attempts, the heat circuit DSI module will LOCKOUT until

it is manually reset. To reset the DSI system, open and close the main door and restart the dryer (press the “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.
