TRANSFORMER WIRING

120 VAC WIRING

For 120 VAC input power to the unit, connect the black wire to the “L1” or hot leg of the power supply. Connect

the white wire to the “Ret” or neutral leg of the power supply. Attach the wire nut to the red wire. There should

e no connection to the red wire for 120 VAC operation. For Lo NOx pool heaters attach a wire nut to each

red wire independently.

240 VAC WIRING

For 240 VAC input power to the unit, connect the black wire to the “L1” or hot leg of the power supply. Connect

the red wire to the “L2” or second hot leg of the power supply. Attach the wire nut to the white wire. There should

be no connection to the white wire for 240 VAC operation. For Lo NOx pool heaters attach a wire nut to

each white wire independently.

Heater must be electrically grounded and bonded in accordance with local codes, or, in the absence of local

codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70. (Canada - Canadian Electrical

Code, CSA C22.1, Part 1 and Part 2.)

NOTE: Input power to the heater (120 or 240 VAC) can be supplied from the load (pump) side of time clock or

directly from the GFCI power source. It is preferred that full-time power be supplied to the heater from the

GFCI power source, and that the heater be controlled by the fireman’s switch connection or using a two

or three-wire remote. See pages 36-38. If using a switched GFCI power source, the heater could display false

service indicators on the display panel if the pump is turned off.

NOTE: If the transformer’s primary side is wired for 120 VAC and 240 VAC is applied, damage to the trans-

former and PC board may result. Such damages are not covered under manufacturer’s limited warranty.

WARNING: DO NOT attempt to operate the heater at 208 VAC.
