B. TUMBLER (BASKET)
The tumbler (basket) is made of 14-gauge stainless steel perforated panels, five (5) stainless steel ribs, and two
(2) tumbler rings. The tumbler (basket) is a completely welded assembly so the perforated panels are not
removable.
C. AIR BLOWER DRIVE SYSTEM
The impellor (fan) used in the ML-410 dryer is a 22-1/4” (56.52 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 25 HP (18.64 kw) 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. AIR JET SYSTEM
The Air Jet System is activated at the end of a drying cycle to clean lint accumulation off of the blower (impellor/
fan).
E. 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) L.E.D. (light
emitting diode) display will show “door.”
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. (light emitting diode) display will show “lint door open.”
3. Tumbler (Basket) Manual Reset Hi-Limit Safety Thermostat
This disc temperature switch has a setting of 225º F (107º C). It is located below the tumbler (basket) on
the temperature sensor bracket, along side the computer (microprocessor) sensor, and is an automatic reset
type switch. Access to this switch is gained by sliding/pulling the lint basket completely out of the dryer.
This switch backs up the computer (microprocessor) sensor and in case of a computer (microprocessor)
malfunction will prevent the tumbler’s (basket’s) temperature from becoming excessive. If this switch
trips, the gas flow to the burner boxes will be shut down; however, and the Phase 7 microprocessor controller
(computer) will display “exhaust high temp fault.”
