Preparing for Your New Portable Spa
230 Volt Electrical Installation
All 230V 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 8.
The electrical wiring of this spa must meet the requirements of 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.
RCD and Wiring Requirements
The power supplied to the spa must be on a dedicated RCD protected circuit 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 wiring requirements.
When wires larger than #6 AWG are required, install a junction box near the spa and use #6 AWG wire between the junction box and the spa.
Wire runs over 26 m must increase wire gauge to the next lower number. For example: A normal 50 amp RCD with four #8 AWG copper wires run over 26 m would require you to go to four #6 AWG copper wires.
Testing the RCD Breaker
Test the RCD breaker prior to first use and periodically when the spa is powered. To test the RCD breaker follow these instructions (spa should be operating):
1.Press the TEST button on the RCD. The RCD will trip and the spa will shut off.
2.Reset the RCD 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.
