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.
