NOTE: If the heater is converted to accept 120V, the
“Hot” wire of the 120V power supply has to be
connected to the black wire (ACH1) on the power
distribution board and the “Neutral” wire of the
120V power supply has to be connected to the
red wire (ACN1) of the power distribution board.
Please see Figure 15 for details.
Maintenance Disconnect Means - The National
Electrical Code
®
(NEC
®
) requires one or more
means to simultaneously disconnect all ungrounded
conductors to be provided for all utilization
equipment other than lighting. Each means shall
be readily accessible and within sight from its
equipment and shall be located at least 1.5 m (5
ft) horizontally from the inside walls of a pool or
spa unless separated from the open water by a
permanently installed barrier that provides a 1.5 m (5
ft) reach path or greater.
GFCI Protection - Circuits serving gas-fi red
swimming pool and spa water heaters operating
at voltages above the low-voltage contact limit per
NEC
®
shall be provided with GFCI protection.
Canadian Electrical Code requires GFCI protection
for all equipment located within 3 m of the inside
walls of a pool or spa, unless separated from the
pool or spa area by a fence, wall, or other permanent
barrier.
6.3 Input Voltage and Conversion
The heater comes factory-wired for installation with
240 Volt, 60 Hz AC fi eld electrical supply. If the
use of 120 Volt, 60 Hz AC fi eld electrical supply is
required, You must fi rst change the position of the
voltage selector board on the power distribution
board. See Figure 16.
• Ensure that all electrical power is shut off to the
heater at the breaker.
• Ensure that the fi lter pump is off and will stay off
for the remainder of the procedure.
• Follow service access instructions from Section
6.1.
Locate the power distribution board in the lower
right hand section of the raceway.
Using scissors, clip the zip tie securing the
voltage selector board into the power distribution
board.
Remove and rotate the voltage selector board
180°. The printed message “FOR 120 VAC” will be
displayed above the card connection pins.
Reinstall voltage selector board.
NOTE: The voltage selector board is keyed so that it will
fi t in only one direction for either selected voltage
(either side of the board).
WARNING
ELECTRICAL SHOCK HAZARD. To avoid an electrical shock hazard,
which can result in serious injury or death, ensure that all electrical
power to the system is turned off before approaching, inspecting, or
troubleshooting any leaking plumbing that may have caused electrical
devices in the surrounding area to get wet.
