IMPORTANT NOTICE: The electrical wiring of this hot tub must meet the
requirements of the National Electrical Code (NEC) and any applicable
state or local codes. The electrical circuit must be installed by a quali-
fied electrician and approved by a local building/electrical inspection
authority.
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 instruc-
tions will void both the independent testing agency listing and the
manufacturer's warranty.
2. The power supplied to this hot tub must be a dedicated circuit with no
other appliances or lights sharing the power provided by the circuit.
3. To determine the current, voltage and wire size required, refer to
Power Supply Options and Requirements, page 14.
– Wire size must be appropriate per NEC and/or local codes.
– We recommend type THHN wire.
– 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.
4. The electrical supply for this product must include a suitably rated
switch or circuit breaker to open all ungrounded supply conductors
to comply with Section 422-20 of the National Electrical Code, ANSI/
NFPA 70. The disconnecting means must be readily accessible to
the hot tub's occupant but installed at least 5 feet (1.5m) from hot tub
water.
5. The electrical circuit supplied for the hot tub must include a suitable
ground fault circuit interruptor (GFCI) as required by NEC Article 680-

6. To gain access to the hot tub's power terminal block, remove the
cabinet panel on the control panel side of all models. Then open the
door to the control box. (Figure A, page 12).
7. Use the appropriate power supply inlet and remove the panel from
the front of the hot tub to allow you to feed the cable through to the
control box. Install the cable with connector through the large opening
provided in the bottom of the control box.
8. Connect wires, color to color, on terminal blocks TB1 and ground
(Figure C, page 12). TIGHTEN SECURELY! All wires must be
hooked up or damage could result.
