DESCRIPTION OF PARTS
A. CONTROL BOX
Lifting the control door and opening the
computer panel will reveal the control box.
Inside the control box are
ALL the electronic
control components. Located on the back of
the control panel is the computer. Included in
the control box are the 30-position block, fuse
block, and transformer.
B. DRIVE MOTOR
The T.E.F.C. (Totally Enclosed, Fan-Cooled) drive motor
is located approximately lower center of the dryer. It sits
on an adjustable base so that the motor can be easily
adjusted to the left or right, up or down, forward or
backward. The drive motor is a 3/4 HP motor and operates
on 208 to 460 volts, 3-phase (3ø), 50/60 Hz.
C. HSI (HOT SURFACE IGNITION) MODULE (Gas Models Only)
The HSI (Hot Surface Ignition) system consists of a
microprocessor (computer) based control module,
along with a hot surface ignitor probe, and a flame
probe assembly. The hot surface ignitor is a silicon
carbide ignitor that upon application of 24 VAC will
glow bright orange for the inter-purge time period.
Upon ignition, the resistance in the flame sensor
electrode changes and the information is sent to the
HSI module via the sensor probe lead connection to
the module. Once the resistance is changed and
sensed, the HSI module will sustain the gas flow
(provide 24 VAC power to the gas valve).
