Electrical Requirements – US and Canada

All 240V spas must be permanently connected (hard wired) to the power supply. These instructions de- scribe the only acceptable electrical wiring procedure. Spas wired in any other way will void your warranty and may result in serious injury. See the wiring dia- gram on page 14.

When installed in the United States, the electrical wiring of this spa must meet the requirements of Na- tional Electric Code, ANSI/NFPA 70-2008 and any ap- plicable local, state, and federal codes. The electrical circuit must be installed by an electrical contractor and approved by a local building / electrical inspec- tor.

GFCI and Wiring Requirements

The power supplied to the spa must be on a dedi- cated 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 below to determine your GFCI and wir- ing 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 cop- per wires.

Read and follow the heater manufacturer’s safety and installation instructions prior to installation and op- eration. Incorrect installation may damage the heater and void its warranty.

Testing the GFCI Breaker

Test the GFCI breaker prior to first use and periodical- ly when the spa is powered. To test the GFCI breaker follow these instructions (spa should be operating):

1.Press the TEST button on the GFCI. The GFCI will trip and the spa will shut off.

2.Reset the GFCI breaker by switching the breaker to the full OFF position, wait a moment, then turn the breaker back on. The spa should have power again.
