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

electrical contractor and approved by a local
building or electrical inspector .

240V GFCI and Wiring Requirements

All VS500 control systems are set at the factory to run on the low power setting for low amperage 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 or 60 amp operation.
Warning: Never set a spa to run on high power without installing a properly rated GFCI .

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 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 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 #8 AWG copper wires run
over 85 feet would require you to go to four #6 AWG
copper wires.
