240V GFCI and Wiring Requirements
The control system is set at the factory to run on the low power setting for 40 amp operation. This is the
default setting. Spa owners can have their installer change this setting so the spa will run on high power for
50 amp operation.
Warning: Never set a spa to run on high power without installing a properly rated GFCI .

One 30 amp GFCI Four #8 AWG copper wires

One 40 amp GFCI Four #8 AWG copper wires
All 240V spas must be permanently connected (hard-
wired) to the power supply. See the wiring diagram
on page 8 .
These instructions describe the only accept-
able electrical wiring procedure . Spas wired
in any other way will void your warranty and
may result in serious injury .
When installed in the United States, the electrical
wiring of this spa must meet the requirements of
National Electric Code, ANSI/NFPA 70-2008 and any
applicable local, state, and federal codes.
240 Volt Electrical Installation
Use the table below to determine your GFCI and wir-
ing requirements.
When NEC requires the use of wires larger than #6
AWG, install a junction box near the spa and use #6
AWG wire between the junction box and the spa.
Wire runs over 85 feet must increase wire gauge to
the next lower number. For example: A normal 50
amp GFCI with four #8 AWG Copper wires run over
85 feet would require you to go to four #6 AWG cop-
per wires.
Read and follow the heater manufacturer’s safety
and installation instructions prior to installation and
operation. Incorrect installation may damage the
heater and void its warranty.
Testing the GFCI Breaker
Test the GFCI breaker prior to fi rst use and periodical-
ly when the spa is powered. To test the GFCI breaker
follow these instructions (spa should be operating):
Press the TEST button on the GFCI. The GFCI will
1.
trip and the spa will shut off.
Reset the GFCI breaker by switching the breaker
2.
to the full OFF position, wait a moment, then
turn the breaker back on. The spa should have
power again.
The electrical circuit must be installed by an
electrical contractor and approved by a local
building or electrical inspector .
Failure to comply with state and local codes
may result in fi re or personal injury and will
be the sole responsibility of the spa owner .
The power supplied to the spa must be on a dedi-
cated GFCI protected circuit as required by ANSI/
NFPA 70 with no other appliances or lights sharing
the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
