MAINTENANCE

a

! WARNING

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

The heater requires no special maintenance other than occasional cleaning to prevent excess accumulation of dust and lint on surfaces. It is important for the reflectors to be kept clean to obtain the maximum radiant output. If used as a movable unit, the cart and cord should be checked periodically to make sure the hardware remains tight and cart and cord are not damaged. Do not continue to use the heater if damaged.

Element Replacement (Contact Factory for Part Number.)

1.Remove Terminal Box Cover.

2.Disconnect lead wires from heater terminals.

3.Remove safety grilles.

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 Marley Engineered Products elements. 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.

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