Preparing for Your New Portable Spa
120 Volt Electrical Installation
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.
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 will 2.
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!
240 Volt Electrical Installation
All 240V spas must be permanently connected
(hardwired) to the power supply. 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.
This is the only acceptable electrical wiring procedure.
Spas wired in any other way will void your warranty. See
the wiring diagram on page 7.
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. The electrical circuit must
be installed by an electrical contractor and approved by
a local building / electrical inspector.
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.
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.
