1. This hot tub must be permanently connected (hard-wired) to the power
supply. No plug-in connections or extension cords are to be used in
conjunction with the operation of this hot tub. Supplying power to
the hot tub which is not in accordance with these instructions will void

All wiring must be copper to ensure proper connections. Do not use
aluminum wire.
• When using wire larger than #6, add a junction box near the hot tub
and reduce to short lengths of #6 wire to connect to the hot tub.

or circuit breaker to open all ungrounded supply conductors to comply
with Section 422-20 of the National Electrical Code, ANSI/NFPA 70. The
