B. Avoid contact between heater and combustible material. C. Keep combustible materials far enough away to be free of the effects of high temperatures. © 2010 Chromalox, Inc. WIRING CAUTION: Hazard of Electric Shock. Any installation involving electric heaters must be effectively grounded in accordance with National Electrical Codes to eliminate shock hazard. 1. Electrical wiring to heater must be installed in accordance with the National Electrical Code and local electric codes. 2. When element wattages are not equal, heaters must not be connected in series. 3. Electrical wiring to heater should be contained in Rigid Conduit or in sealed Flexible Metal hose to keep corrosive vapors and liquid out of the terminal housing. Conduit should terminate at some remote area free of corrosive vapors. If high humidity is encountered, the conduit should slope away from the heater terminals to keep condensate away from the heater. 4. If flexible cord is employed with the heater, a watertight connector should be used for entry of the cord into the terminal box. OPERATION 1.

If heater is used in an electroplating tank, the heater should be grounded externally to the tank wall to mini- mize stray plating currents in heater sheath that may cause sheath corrosion.
