Before servicing the spa, make sure all power to the spa is disconnected. Follow the
following instructions for a successful electrical installation.
1. Unscrew the screws on the front access panel.
2. Carefully pull access panel towards you (away from spa) and pull upward. Set access panel aside.
3. Locate the blue SC-MP 110V/220V spa control box. Loosen the screws on the front of the control
box. Lift the control box cover upward and the terminal block will be exposed.
4. Route the GFCI power cord through the vent hole in the base of the equipment compartment
and out from under the corner of the spa.
NOTE: 110 Volt installations require a 60Hz, single phase, two-wire electrical service plus ground
(Line 1, Neutral and Ground) and must be connected using a minimum supply conductor ampacity
of 20 Amps and a minimum GFCI circuit breaker size of 20Amps.
5. Input the GFCI power cord to the terminal block inside the spa pack.
6. Connect the #8 AWG black wire, from the power cord, to Line 1 on the input terminal block.
7. Connect the #8 AWG ground wire, from the power cord, to the GND (ground) on the input
terminal block.
8. Connect the #8 AWG white wire, from the power cord, to the neutral on the input terminal block.
9. Place a jumper cable between the neutral and Line 2 at the input terminal block.
10. Locate Jumper #1 on the PC board (see wiring diagram) and move Jumper #1 to the right
position (low current mode).
11. Close spa pack cover and re-tighten screws.
