Dimensions/Mounting
NOTE:
The inlet side of the heater is located where the electrical leads and thermocouple wires come out of the
housing. Failure to install the heater in its proper orientation can result in heater damage and is not covered
under the manufacturer’s warranty.
Precautions
1.
Use filtered air. Avoid grease, oil, or oil vapors, corrosive or reactive gases which will damage heater.
Note: When using compressed air a pressure reduction valve and an oil & water separation unit should be
installed to avoid contaminating the heater and reduce heater life.
2.
Operate at safe voltages as shown on the Performance Curves
(see page 6)
. Excess voltage will cause
premature failure.
3.
Always have sufficient airflow through the heater before applying power. Otherwise element will overheat
very quickly, and burn out.
NOTE:
A thermocouple cannot detect temperatures if there is no flow – turn on
flow before applying power, even when a controller with a thermocouple is being used.
4.
Use phase angle fired power controllers. On-Off controllers may shorten heater life (or burnout element).
5.
For closed-loop control, use exposed junction type “K” thermocouple located within one inch of the heater
exit.
6.
For closed-loop control, use a temperature controller with a fast sampling period (<500ms) and minimal
overshoot.
CAUTION: DO NOT Operate Heater Without Air
