Refer to FIGURE 1  
If a 120 V.A.C. circuit is to be used, make wiring changes as fol-  
lows:  
1. Disconnect white wire from heater element terminal “2” and  
connect it to terminal “4.” The heater will now operate at 120  
V.A.C., 750W, 6.3A.

10. This heater includes a visual alarm to warn that parts are get-  
ting excessively hot. If the alarm lights are activated, immedi-  
ately turn the heater off and inspect for any objects on or adja-  
cent to the heater that may cause high temperatures.  
2. For 120 V.A.C, 1500W, 12.5A operation, add the short red  
jumper wire (provided) between terminals “1” and “2”.  
3. Remove alarm light wire leads from terminals “1” and “3” of the  
high temperature limit. Remove white wire lead from limit ter-  
minal “1” and reconnect at limit terminal “3”. Secure wire leads  
with wire tie so there is no interference with unit operation.
