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 9)
. Excess voltage will cause
premature failure.
3. If using a process air temperature thermocouple other then one of the supplied
“K” thermocouple probes it is
highly recommended that one of the exit thermocouples be used with a temperature limiting board to protect
against over temperature protection (TUTCO SureHeat Part #F076359
– set to 1680
°
F (915
°
C)).
4. If using closed-loop control, use a temperature controller with a fast sampling period (<500ms) and minimal
overshoot.
