Protective Earthing:

Dimensions/Mounting
NOTE: The inlet side of the heater is located where the leads/power feedthrus 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 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 (OSRAM SYLVANIA 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.
