1. Turn on power to the over temperature board Turn on power to the power controller Turn on power to the temperature controller Set desired temperature on temperature controller OU ON During operation with steady state airflow the exit temperature should not vary more than a few degrees from set point Although the heater will not burn out with zero airflow if the heater is operated in a vertical downward position and an airflow of 100 SCFH or below is run through the heater the inlet temperature of the heater will exceed 150 F and the Over temperature board will begin to limit power to the heater To Shut Down 1 Turn off power to the temperature controller and the power controller 2 Allow air to continue to flow for a minimum of 1 minute or until exit air temperature is 150 C or less for safety Continue airflow longer if hot equipment components present any potential hazard to personnel 3 Turn off air to the system Replacing Elements Before replacing the element assembly determine the cause of the element failure Prior to powering the system back up make certain that the entire system is operating properly Possible causes of element failure are 1 Normal end of Life 2 Failure in Control System 3 Mechanical Damage to System REPLACEMENT PROCEDURE 1 Turn off power to the system Follow lock out tag out procedures 2 Unscrew the 3 external housing screws and remove the stainless heater housing 3 Unplug elem2.
