IMPORTANT: If during installation the lint door safety chain was disconnected, it must be reconnected or personal injury may result.

10.Rotate the basket (tumbler) and drum by hand to be sure it moves freely.

11.Check bolts, nuts, screws, terminals, and fittings for security.

12.Check basket (tumbler) bearing setscrews to ensure that they are ALL tight.

I. PREOPERATIONAL TESTS

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

3.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.

NOTE: Dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal diagnostics. If ignition is not established after three (3) attempts, the heat circuit in the DSI module will lockout until it is manually reset. To reset the DSI 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) 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.

4.Make a complete operational check of ALL safety related circuits:

a.Door Switches

b.Hi-Limit Thermostats

c.Cycling Thermostat
