Disconnect all power before installing, servicing or replacing heaters. Chromalox Cast-Iron Immersion Heaters are generally used for metal-melting applications such as solder, lead, tin, stereotype metal, babbitt (with 4% or less copper) and other soft metals where maximum working temperature is 950 °F. Note: Not suitable for immersion in zinc or aluminum. 1. Heater Construction Characteristics — A. High quality resistance wire held in place by compacted magnesium oxide in heavy wall steel sheat

5. Rough-in wiring to heater. See Table 2 for line amperes, recommended wire size and conduit size. 6. Wire heater per wiring diagram supplied with this instruction sheet. Note: Power relay(s) are provided as standard on all heaters. WARNING: Prior to operating the heater, verify that the fan hub setscrews are tightened and the push-on clip is secured to assure that the fan blade is securely fastened to the motor shaft. 7. Carefully inspect the completed installation. Rotate the fan blade by han

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
