B. BASKET (TUMBLER)
The basket (tumbler) is made of 14-gauge stainless steel perforated panels, four (4) stainless steel ribs, and two
(2) outer basket (tumbler) rings made of rolled steel angle iron that has been turned on a lathe for smoothness.
The basket (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 an 18-1/4” (46.35 cm) diameter squirrel cage impellor (fan) wheel. It spins
in a counterclockwise (CCW) 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. Manual Reset Basket (Tumbler) Hi-Limit Safety Thermostat
The manual reset basket (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 manual reset hi-limit safety must be manually reset and the Phase 7 computer must be
reset. (Access to the switch is gained by sliding/pulling the lint basket completely out of the dryer.)
4. Burner Box Hi-Limit Safety Thermostats (for Gas Dryers ONLY)
These disk temperature switches have a setting of 330º F (166º C). They are located on the right side of
each burner box, and they are a manual reset type of switch. These switches ensure that there is a proper
airflow through the burner box. Upon a low airflow condition, which may be caused by a clogged lint screen
excessively long or blocked exhaust duct, or improper make-up air, the temperature in the burner boxes will
increase tripping these switches. This will shut off the gas flow to the burner boxes; and the display will
read an error code of “Burner Hi-Limit Fault.” The thermostat must be manually reset and the Phase 7
computer must be reset.
