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 acceptable
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 NEC
70 and any applicable local, state, and federal codes.
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 re or personal injury and will be
the sole responsibility of the spa owner.
The power supplied to the spa must be on a dedicated
GFCI protected circuit as required by NEC 70 with no
other appliances or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table below and on the next page to determine
your GFCI and wiring requirements.
Wire runs over 85 feet must increase wire gauge to
the next lower number. For example: A normal 50
amp GFCI with four #6 AWG copper wires run over 85
feet would require you to go to four #4 AWG copper
wires.
