MAINTENANCE

ELECRIC SHOCK HAZARD. Disconnect all power before servicing or replacing heating elements.

The reflectors should be kept clean to obtain the maximum radiant output.

Element Replacement

1.Remove Terminal Box Cover.

2.Disconnect lead wires from heater terminals.

3.Remove safety grills (if installed).

4.Remove retainer screw located on the reflector at the terminal end.

5.Loosen (2), 3/8" nuts from the terminal box bracket located on the back of the heater and slide the entire heating element assembly out of the reflector assembly.

6.Remove wires and jumper straps as required to replace the failed heating element(s).

7.Remove bulkhead fitting nuts and washers.

8.Remove failed element and replace with a new element.

Replace only with genuine Chromalox "Arctic End" ele- ments. Use of other elements will cause excess temperatures inside terminal box.

9.Place gasket on the bulkhead fitting and insert terminals and fittings into the element holes in the terminal box.

10.Place washers and nuts on bulkhead fittings and tighten.

11.Replace wiring and jumper straps ( see Fig. 4).

12.Reassemble by following the reverse procedures (steps 5 through 1)
