MOUNTING

WARNING: Hazard of Electric Shock. Disconnect all power before installing heater.

WARNING: These heaters are designed for wall or ceiling mounting only. Other modes of mounting voids factory warranty.

1.Height above floor

A.In areas where ceiling height is more than 12 feet, recom- mended mounting height is approximately 10 feet to under- side of heater.

B.For ceiling heights of 12 feet or less, maximum mounting height is determined by use of ceiling mounting brackets

offered with these heaters. Minimum spacing to ceiling is 14-1/4”.

C.In either case, the minimum mounting height is 7 feet from floor to bottom of heater. (See Figures 1 and 2.)

2.Spacing to adjacent walls

A.Rear of case to back wall 11” minimum.

B.Side of case to side wall 12” minimum.

3.If two or more units are operated in the same enclosed space, their discharges should be directed to aid in development of mass air movement for uniform heat dispersal.

4.Controlling thermostats to individual heaters should be mount- ed at shoulder height on inside walls or columns.

WIRING

Note: All wiring should be done in accordance with local codes and the National Electrical Code by a qualified person.

WARNING: Hazard of Electric Shock. Any installa- tion involving electric heaters must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

1.Connect heater according to the voltage and frequency speci- fied on the nameplate and using the appropriate wiring diagram (Figures 3 thru 11).

Note: Be sure to check the voltage rating of the fan motor since it is not necessarily the same as the heater circuit.

2.If an external transformer is used to step down the voltage for operating the fan motor, use appropriate wiring diagram (Figures 8 thru 11).

3.Heaters are not provided with a control switch and should be controlled by externally mounted disconnect switches and/or separately mounted thermostat and control switch as recom- mended in appropriate wiring diagrams (Figures 3 thru 11). Key to proper wiring diagram is the part number (P/N) of inter- nal wiring diagram located on inside of the hinged cover of the terminal box.

4.Protection against overheating is provided by an internal auto- matic thermal cutout which opens the electric circuit if the nor- mal air-flow is restricted or stopped. Cutout automatically energizes heater on removal of the obstruction.
