For 120 V 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 “L2” or neutral leg of the power supply. Attach the wire nut to the red wire. There should be no connection to the red wire for 120V operation. For Low NOx pool heaters wire nut each red wire indepen-

dently.

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 (120/240V) can be supplied from the load (pump) side of time clock or directly from the switch/GFCI power source. It is pre- ferred to make connection to the load/pump side of the time clock. When using the switched GFCI power source the heater could display false service indicators on the delay panel if the pump is turned off.
