1. Connect heater according to the voltage and frequency specified 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 mo

Key to proper wiring diagram is the part number (P/N) of internal wiring diagram located on inside of the hinged cover of the terminal box. 4. Protection against overheating is provided by an internal automatic thermal cutout which opens the electric circuit if the normal air-flow is restricted or stopped. Cutout automatically energizes heater on removal of the obstruction. WIRING DIAGRAMS Figure 3 2 WIRING DIAGRAMS Figure 4 Figure 5 3 WIRING DIAGRAMS Figure 6 Figure 7 4 WIRING DIAGRAMS Figure 8
