Wiring the Heater

cover forward.

Note the location of the terminal block inside the heater.
The terminals on the block are marked Line 1 (L1), Line 2 (L2),
Neutral (N), and Ground. Connect the input service wires to
the appropriate terminal. Connect the ground wire to the
ground lug.
•
Close and secure the cover.

Connect the pump using the receptacle located on the side
of the heater.
Air Switch Installation
This heater is supplied with an air switch as a standard feature, but its installation and use is op-
tional. The air switch can be mounted on the lip of the pool or any other convenient location
and allows the user to turn the heater system on and off when the control switch on the front
panel is set for timer operation.
To install the Air Switch, drill a XX hole on the lip of the pool or another convenient location.
Mount the Air Switch, then press the clear tubing supplied onto the end of the switch. Run the
tubing to the Air Switch receptacle on the side of the heater.
