Electrical Power Connections

Installations must follow these codes:

•National Electrical Code and any other national, state, provincial or local codes or regulations hav- ing jurisdiction.

•Safety wiring must be NEC Class 1.

•Heater must be electrically grounded as required by the NEC.

•In Canada, CSA C22. 1 C.E.C. Part 1.

The heater is wired for 120 VAC, <12 amps. The volt- age is indicated on the tie-in leads. Consult the wiring diagram shipped with the heater in the instruction packet. The remote tank control stat, thermostat, or electronic heater control (as applicable) may be con- nected to the stage selector terminal (See wiring diagram). 24 VAC is supplied to this connection through the heater transformer. DO NOT attach any voltage to the stage selector terminals. Before starting the heater check to ensure proper voltage to the heater and pump.

Install a separate disconnect means for each load. Use appropriately sized wire as defined by NEC, CSA and/or local code. All primary wiring should be 125% of minimum rating.

If any of the original wire as supplied with the heater must be replaced, it must be replaced with 105°C wire or its equivalent.

Field-Connected Controllers

It is strongly recommended that all individually-pow- ered control modules and the heater should be supplied from the same power source.

NOTE: Field-supplied isolation relays should be installed when field-connected controllers are mounted more than 50 equivalent feet (18 Ga) from heater.

If the heater does not have a factory-wired stage con- troller, it is factory-wired in an on-off configuration with other stage terminals jumpered.

To field-connect a stage controller, remove factory- installed jumpers and wire stage controller as shown in Fig. 19–22.

Making the Electrical Connections

Refer to Fig. 16–22.

WARNING: Using a multi-meter, check the following voltages at the terminal block inside the unit. Make sure proper polarity is followed and house ground is proven. (See Fig. 18.)

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

2.Turn off all power to the heater. Verify that power has been turned off by testing with a multi-meter
