ELECTRICAL
REQUIREMENT
DO NOT POWER THE SPA WITHOUT
FIRST FILLING WITH WATER!
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 spa 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 ft (1.5 m) of any metal
surfaces must ground the metal surfaces to the
hot tub. Use an 8 AWG solid copper wire and
attach it to the grounding lug on the control,
located in the equipment compartment.
2. Only a licensed electrician may install power to
the spa.
3. Power supply installation must include a
suitably rated ground fault circuit interrupter
(GFCI) as required by NEC. 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 spa must include a
suitable rated switch or circuit breaker to open
all ungrounded supply conductors to comply
with the National Electric Code. The
disconnecting means must be readily
accessible to the spa's occupant but installed
at least 5 feet (1.5 m) from the spa water.
5. 230V Power supply lines must be hard wired
into the control box. 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. A ground line must be provided that is as
large as the largest current carrying conductor,
but no less than 8 AWG. Use copper wiring only.
7. Please open the front cover of the control box,
and follow the instructions and wiring diagram
printed on the backside.
8. All 115 V powered models must use the
provided 15 ft (4.5 m) GFCI cord and be
pluged directly into a dedicated grounded wall
outlet between 6' (1.8 m) and 10' (3 m) from
the spa.
9. CAUTION, 230V POWERED SPAS – These
spas must be hard wired with a GFCI 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.
Equipment access is below the topside
control panel on most spas.
