6.0 Electrical Wiring Instructions
IMPORTANT
NOTICE: The electrical wiring of this spa 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 qualified electrician and approved by a local build-
ing/electrical inspection authority.
1. This spa 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 spa. Supplying power to
the spa which is not in accordance with these instructions will void
both the independent testing agency listing and the manufacturer’s
warranty.
2. The power supplied to this spa must be a dedicated circuit with no
other appliances or lights sharing the power provided by the circuit.
3. To determine the current and voltage and wire size required, refer to
section 5.0 “Power Requirements” (Page 7).
• 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 (10mm
2
), add a junction box near the
spa and reduce to short lengths of #6 (10mm
2
) wire to connect to spa.
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 spa’s occupant
but installed at least 5 feet (1.5m) from spa water.
5. The electrical circuit supplied for the spa must include a suitable
ground fault circuit interruptor (GFCI) as required by NEC Article 680-42.
6. To gain access to the spa’s power terminal block, remove the screws
securing the panel under the controls. Then remove the four control box
door screws and door (Figure B, Page 10).
7. Select the power supply inlet you want to use (Figure A, Page 10) and
remove the short cabinet panel from the front of the spa to allow you to
feed the cable through to the control box. Install the cable with connec-
tor through the large opening provided in the bottom of the control box.
8. Connect wires, color to color, on terminal blocks TB1 and TB3 (Figures
C-D, Page 10). TIGHTEN SECURELY! All wires must be hooked up secure-
ly or damage could result.
