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

PRODUCT OPERATION

THEORY OF OPERATION

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)).
