Making the Electrical Connections

Refer to Fig. 16-19.

1.Verify that circuit breaker is properly sized by referring to heater rating plate. A dedicated circuit breaker should be provided.

2.NOTE: Current draw noted on rating plate does not include pump current.

3.Turn off all power to the heater. Verify that power has been turned off by testing with a multi-meter prior to working with any electrical connections or components.

4.Observe proper wire colors while making electri- cal connections. Many electronic controls are polarity sensitive. Components damaged by im-

proper electrical installation are not covered by warranty.

5.Provide overload protection and a disconnect means for equipment serviceability as required by local and state code.

6.Install heater controls, thermostats, or building management systems in accordance with the appli- cable manufacturers’ instructions.

7.Conduit should not be used as the earth ground.

NOTICE: A grounding electrode conductor shall be used to connect the equipment grounding conductors, the equipment enclosures, and the grounded service conductor to the grounding electrode.

Field Wiring Connection

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause im- proper and dangerous operation. Verify proper operation after servicing.

DANGER: SHOCK HAZARD

Make sure electrical power to the heater is discon- nected to avoid potential serious injury or damage to components.
