Electrical Installation -- Europe
Preparing forYour New Inground
All 230V 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.
This the only acceptable electrical wiring procedure. Spas wired in any other way will void your warranty. See the wiring diagram on page 9.
The electrical wiring of this spa must meet the re- quirements 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 dedi- cated 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 wir- ing 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 85 feet must increase wire gauge to the next lower number. For example: A normal 50 amp RCD with four #8 AWG copper wires run over 85 feet would require you to go to four #6 AWG cop- per wires.
Testing the RCD Breaker
Test the RCD breaker prior to first use and periodical- ly 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.
