1. Convertible 120/240V Denali/Tacoma Models Only:
• 120V “Plug-in” Operation: This spa must operate on the
supplied 10 foot (3m) 120V GFCI cord at its original length

GFCI cord must be discarded for 240V heater operation.
This spa must be hard-wired. Supplying power to either

This spa must be permanently connected (hard-wired) to the
power supply. No plug-in connections or extension cords are to

All wiring must be copper to ensure proper connections. Do

box near the spa and reduce to short lengths of #8
(8.4 mm²) wire to connect to the spa.
