Always follow applicable local, state and federal
codes and guidelines.
Use only a dedicated electrical line with a 20 amp
breaker.
Cord-and-plug connections may not use a cord longer
than 15 feet (4.6 m) and must be plugged into a
dedicated 20 amp GFCI connection (NEC 680.42(A)
(2)). Do not use extension cords!
Always use a weatherproof-covered receptacle.
Receptacle shall be located not less than 5 feet (1.5
m) from and not exceeding 10 feet (3.0 m) from the
inside wall of the spa. (NEC 680.43(A))
Do not bury the power cord. If your cord becomes
damaged, replace it before next usage.
120 Volt Electrical Installation
All 120V spas must have a GFCI. This can be either a
20 amp GFCI receptacle or a 20 amp GFCI cord and
plug kit as shown (CKIT110 - P/N ELE09700086).
Test the GFCI plug prior to rst use and periodically
when the spa is powered. To test the GFCI plug
version, follow these instructions. (Spa should already
be plugged in and operational.)
Press the TEST button on the GFCI. The GFCI will 1.
trip and the spa will stop operating.
Press the RESET button on the GFCI. The GFCI 2.
will reset and the spa will turn back on.
The spa is now safe to use.
If the GFCI trips while the spa is in use, press the
RESET button. If the GFCI does not reset, unplug the
spa and call your local Cal Spas dealer for service. DO
NOT USE THE SPA!
All 240V spas must be permanently connected
(hardwired) to the power supply. See the wiring
diagram on page 7.
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
National Electric Code, ANSI/NFPA 70-2008 and any
applicable local, state, and federal codes.
240 Volt Electrical Installation
Use the table on the next page to determine your
GFCI and wiring 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
copper 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 rst use and periodically
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 re or personal injury and will
be the sole responsibility of the spa owner.
GFCI and Wiring Requirements
The power supplied to the spa must be on a dedicated
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.
