OPERATION

CAUTION: To avoid possible damage to the heater, do not energize until the tank is filled with fluid. Recommended fluid level is 2” above the heater tube or pipe.

1.Turn the master circuit breaker off and open the control box door.

2.Set the indicating temperature control at the desired temperature and the over-temperature cutout 50°F above this temperature.

3.Close the control box door and turn the circuit breaker on. To energize the heater circuits, turn the on-off selector switch to the “on” position.

MAINTENANCE

CAUTION: Hazard of Electrical Shock. Disconnect all power before servicing or replacing the heaters.

1. To remove the heating element, first turn the circuit breaker to the off position. Then open the control box door and remove the screws from the sheet metal isolating panel located in the lower half of the control box.

2. When removing the heating elements, make certain that the ter- minals and the ceramic insulators (RSTO type only) do not contact oil or any other liquid foreign matter.

Note: Chromalox cannot be responsible for failures or damage caused by contamination on the ceramic insulators.

3.Next remove the element wiring and finally the element mounting screw. Now pull the element straight out of the heat- ing tube.

4.Note: Check electrical connections at heater terminals and tighten if necessary. This will help avoid hot temrinals which could destroy wiring insulation or heater terminals.
