J. 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.GAS MODELS ONLY

a.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: If the dryer is equipped with a Direct Spark Ignition (DSI) system, the DSI control module has internal diagnostics. If ignition is not established within three (3) attempts, the heat circuit in the DSI control module will “LOCKOUT” until manually reset. To reset the DSI system, open and close the main door and restart the dryer.

b.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 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 (26.2 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 Switch(es)

b.Hi-Limit Thermostats

c.Cycling Thermostat

d.GAS AND ELECTRIC MODELS ONLY - Sail Switch
