PRODUCT OPERATION

THEORY OF OPERATION

HEATER OPERATION

This dryer uses a dual element heater. De-
pending on the selected temperature, either
one or both of the elements will be in the circuit
during the drying mode.

In the Normal temperature setting, both ele-
ments are in the circuit. One element (R1) is
controlled by the operating thermostat. As the
thermostat cycles, the second element (R2)
remains in the circuit, and maintains a consis-
tent operating temperature.

Manual Reset Thermostat

Self-Resetting Thermostat

Dual Heating Elements

In the Low temperature setting, a switch opens
the circuit to R2, and it is removed, and drying
takes place with the R1 element only.

SAFETY THERMOSTATS

A pair of safety thermostats is located on the
dual element housing. One is a manual reset
thermostat, (302

°

F (150

°

C)), and the other is a

self-resetting thermostat (194

°

F (90

°

C)).
