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 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.
a) 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 DSI module will
“LOCKOUT” until it is manually reset. To reset the DSI system, open and close the main door and
restart the dryer.
b) If the dryer is equipped with a Hot Surface Ignition (HSI) system, the HSI control module has internal
diagnostics. If ignition is not established after the first attempt, the heat circuit HSI module will
“LOCKOUT” until it is manually reset. To reset the HSI system, open and close the main door and
restart the dryer.
NOTE:
During the purging period, check to be sure that
ALL
gas shutoff valves are open.
2) Once ignition is established, 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 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.
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 the dryer. The dryer should start but the heat circuit
should not be
activated (on). If
the heat (burner) does activate, shut the dryer off and make the necessary adjustments.
7. A reversing basket (tumbler) dryer
must never be
operated with less than a 63 pound (28.57 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.
