Heater Indicator Light
The heater has a green indicator light which will flash on and
off. This indicates that the controller is operating normally. If
the green indicator is not flashing then the controller may not
be operating properly. If this occurs, disconnect power and
have the heater repaired by an McElroy Authorized Service
Center.
The heater has a red indicator light on the handle at the
bottom of the temperature scale. When the heater is plugged
in and preheating the red light glows steadily until the set
temperature is reached. The red light then goes off and on as
the heater maintains temperature.
If the heater is not operating properly, the control will attempt
to turn the heater off and the red indicator light will flash
rapidly. If this occurs, disconnect the power and take it to a
McElroy Authorized Service Center for repair.

Adjusting Heater Temperature
Turn knob to desired temperature. Measure the heater surface
temperature with a pyrometer. Any variance must be corrected to
the pyrometer reading.
Loosen setscrew in the knob. Turn knob to point to the same
temperature as the pyrometer. Tighten setscrew in the knob.
Turn knob to desired temperature. Allow heater to stabilize at the
new temperature (5 to 10 minutes) after adjusting.
The thermometer on the heater body indicates internal
temperature and should be used as a reference only.
