MAINTENANCE

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be installed or serviced by a qualified person in accordance with the National Electrical Code, NFPA 70.

1.Make certain both the terminals and the ceramic insulators are free from contact with oil, liquid, or other foreign matter.

NOTE: Chromalox cannot be responsible for failures or damage caused by contamination on the ceramic insulators. Make certain the heaters are not exposed to contaminants.

2.Check electrical connections at heater terminals and tighten if neces- sary. This will help avoid hot terminals which may destroy wire insu- lation or heater terminals

3.Check overheat operation to assure heater protection.

Element Replacement - Moisture Resistant Housing Only (E4 Option)

1.To remove the OCE heating elements, first turn the circuit breaker to the off position.

2.Next remove the housing lid, element wiring and the element mount- ing screw. Now pull the element straight out of the heating tube. NOTE: OCE elements should only be bent in a vertical plane with ground strap on the bottom.

3.When removing the heating elements, make certain that the terminals

and the ceramic insulators do not contact oil or any other liquid foreign matter. NOTE: Chromalox cannot be responsible for failures or dam- age caused by contamination on the ceramic insulators.

4.Installation is the reverse of the above.

Element Replacement - Hazardous Locations, Explosion Resistant Housing Only (E2 option)

1.To remove the OCE heating assembly, first turn the circuit breaker to the off position.

2.Next remove the housing lid, element wiring, and 5/16” bolting around the element flamepath module. If needed, (2) 1/4-20x2” bolts may be used to break loose the module from the flange. Turn bolts evenly until module is free. The flamepath module will be re-used, so disconnected the heating element from the module pins. Now pull the element assembly out of the heating tube. NOTE: OCE elements should only be bent in a vertical plane with ground strap on the bottom.

3.When removing the heating elements, make certain that the terminals and the ceramic insulators 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.

4.Inspect the element assembly flange and mating surface for any debris, oils, or contamination. NOTE: Surfaces must be in suitable condition to ensure proper hazardous rating.

5.Connect the new element to the flamepath module and slide into tube. Flamepath module bolting must be tightened to XXX ft. lbs. of torque.

6.Reattach element wiring. When reinstalling housing lid, be sure to prop- erly align gasket, and tighten housing bolts to 40-50 in-lbs.
