ELECTRIC REQUIREMENTS
DANGER – RISK OF ELECTRIC SHOCK
Installations that do not conform to the following procedures and requirements may expose users to electric shock. Non-conforming
installations will not be covered under warranty.
If installed in the United States, the electrical wiring of this hot tub must meet the requirements of the
National Electric Code (NEC) and any applicable state or local codes. The electrical circuit must be
installed by an electrical contractor and approved by a local building electrical inspection authority.
1.
Installations within 5 feet (1.5m) of any metal surfaces must ground the metal surfaces to the hot tub. Use an 8 AWG
(8.4mm
2
)
solid copper wire and attach it to the grounding lug on the power pack, located in the equipment compartment.
2.
Only a licensed electrician may install power to the hot tub.
3.
Power supply installation must include a suitably rated ground fault interrupter (GFCI) as required by NEC Article 680-42.
The circuit breaker must be dedicated and should not be shared with any other appliances. It must be labeled and easily
accessible to users.
4.
The electrical supply for the hot tub must include a suitable rated switch or circuit breaker to open all ungrounded supply
conductors to comply with Section 422-20 of the National Electric Code, ANSI/NFPA 70. The disconnecting means must be
readily accessible to the hot tub’s occupant but installed at least 5 feet (1.5m) from the hot tub water.
5.
Power supply lines must be hard wired into the power pack. DO NOT use extension or plug-type cords of any kind. The use
of a shut-off box near the hot tub is also recommended. This box provides a quick and convenient method to shut off power
to the hot tub for emergencies and maintenance.
6.
Supply lines must be properly sized as per the NEC (National Electric Code). A ground line must be provided that is as large
as the largest current carrying conductor, but no less than 8 AWG
(8.4mm
2
)
. Use copper wiring only.
7.
Please open the front cover of the power pack, and follow the instructions and wiring diagram printed on the backside.
8.
All 120 VAC powered models must use the provided 15 foot GFCI cord plugged directly into a
dedicated grounded wall
outlet
. Actual exposed cord length will vary by model but never be less than 10 feet.
Never lengthen the supplied GFCI
cord or use an extension cord with it for any reason!
9.
CAUTION, 240 VAC POWERED HOT TUBS – These hot tubs must be hard wired to your household electrical service box
only. Do not use an extension cord or any other disconnect-able power cord. The use of an extension cord or a disconnect-
able power cord is highly dangerous and will void all warranties!
•
Wire size must be appropriate per NEC and/or local codes.
•
Wire size is determined by length of run from breaker box to spa and maximum current draw.
•
THHN copper core wire is recommended.
•
All wiring must be copper to ensure adequate connections. Do not use aluminum wire.
•
When using wire larger than #6, add a junction box near the hot tub and reduce to short lengths of #6 wire between
the junction box and the hot tub.
CIRCUIT BREAKER REQUIREMENTS
A new GFCI circuit breaker must be used for your hot tub installation. Do not use an existing breaker, as its condition is unknown.

On 240 VAC systems always use a 4 wire system. ON all systems, the hot tub must be connected to a dedicated GFCI circuit breaker
that is not shared with any other equipment. Do not use extension or plug type cords of any kind.
For 120 VAC to 240 VAC or 240 VAC to 120 VAC conversion instructions see backside of spa pack cover plate for your spa’s
specific instructions.
CONVERSION MUST BE PERFORMED BY A QUALIFIED LICENSED ELECTRICIAN
120 VAC GFCI BREAKERS HAVE AN AUTOMATIC RESET (WHEN EQUIPPED)—IF GFCI DOES
NOT RESET PLEASE CONTACT YOUR DEALER FOR REPAIRS.
