ELECTRIC SHOCK HAZARD. Any installation involv- ing electric heaters must be performed by a quali- fied person and must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

Ensure the correct Wiring Guide is used for your heated medium and model type, and ensure the correct wiring diagram is used. Miswiring could

result in an unsafe wattage.

1.Be sure line voltage matches your intended voltage and does not exceed the max voltage on the nameplate.

2.Electric wiring to heater must be installed in accordance with local and National Electrical Codes by a qualified person as defined in the NEC.

3.Power controllers must be used with this product.

4.Electrical wiring to heater should be with rigid conduit or flex- ible conduit to keep corrosive vapors and liquids out of the electrical enclosure. If high humidity is encountered, the con- duit should slope down away from the heater.

5.Refer to appropriate wiring diagram for your model heater from the Wiring Guide (on next two pages).

The specific Wiring Guide provides easy to follow steps to determine the appropriate wiring diagram for your heater instal- lation. Figure 1 may be referenced as a general diagram of how a contactor and temperature control are used in conjunction with the specific wiring diagrams.

6.Use ground fault protection equipment where electrical insula- tion failure can cause process problems.

7.When element wattages are not equal, heaters must not be con- nected in series.

8.If flexible cord is employed, a watertight connector should be used for entry of the cord into the electrical enclosure. Outdoor applications require liquid-tight conduit and connectors.

9.If application uses a standard PCN at different voltages and kWs from the Wiring Guide, refer to the Customer Wiring Guide Supplement if included with these instructions, or con- tact Customer Service at (800) 368-2493.
