B. TUMBLER
The tumbler is made of 14-gauge stainless steel perforated panels, four (4) stainless steel ribs, and two (2) outer
tumbler rings made of rolled steel angle iron that has been turned on a lathe for smoothness. The tumbler is a
completely welded assembly, so the perforated panels are not removable.
C. AIR BLOWER DRIVE SYSTEM
The impellor (fan) used in the dryer is a 15-inch diameter squirrel cage impellor (fan) wheel. It spins in a
counterclockwise direction looking at the back of the blower housing.
The impellor (fan) shaft is mounted in two (2) pillow block bearings, and the shaft is driven by two (2) B-section
V-belts connected to the blower motor.
The blower motor is mounted on an adjustable base. The motor position can be easily adjusted, so that proper
tension can be maintained on the V-belts.
D. SAFETY DEVICES
1. Load/Unload Door Switches
There are two (2) of these switches located above the main loading doors. These switches ensure that the
doors are closed before the dryer can start and ensures that the doors are fully open before the dryer will tilt.
If the dryer is started when the load doors are open, the microprocessor controller (computer) light emitting
diode (L.E.D.) display will show “front door not closed” or “rear door not closed” for 2 door dryers.
2. Lint Basket Switch
This switch ensures that the lint basket is closed before the dryer can start. This switch is located at the
front of the dryer at the right side of the lint basket. If the lint basket is open when the dryer is started, the
microprocessor controller (computer) L.E.D. will display “Lint Drawer Open” and will not reset until the lint
drawer has been closed. For a “clean lint” prompt the lint drawer must remain open for 15-seconds.
3. Automatic Reset Tumbler Hi-Limit Safety Thermostat
The automatic reset tumbler hi-limit switch is a thermostat type switch located above the lint basket. Its
function is to discontinue heat (flame) in the event of an over temperature situation (above 225° F [107° C]).
This will shut off the gas flow to the burner boxes; and the display will read an error code of “tumbler hi-limit
fault.” The automatic reset hi-limit safety will automatically reset once the temperature has fallen below
225° F (107° C). The Phase 7 computer
must be
reset by pressing the Stop key, then the display will read
“READY.”
