ELECTRICAL REQUIREMENTS AND
PRECAUTIONS
Your Hot Spring
®
spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly
wired circuit will negate many of the spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries.
Please read and follow the electrical installation requirements and instructions for your specific spa model completely!

E:: All Hot Spring spa models are equipped with a power indicator which, in addition to showing the spa has power to it, has a
diagnostic function as well. It will begin blinking if the heater high-limit thermostat has tripped. If the power indicator light is blinking, follow the
instructions in the Troubleshooting section to identify and correct the cause. The power indicator will stop blinking once the problem has been
corrected.

HOT SPRING SPAS MUST BE WIRED IN ACCORDANCE WITH ALL APPLICABLE LOCAL ELECTRICAL CODES. ALL ELECTRICAL WORK
SHOULD BE DONE BY AN EXPERIENCED, LICENSED ELECTRICIAN. WE RECOMMEND THE USE OF APPROPRIATE ELECTRICAL CONDUIT,
FITTINGS, AND WIRE FOR ALL CIRCUITS.
An electrical subpanel containing two GFCI breakers is included with each 230 volt spa. We recommend that this subpanel be used to supply
power and protect the spa.
This subpanel requires a 50 amp, single phase, 230 volt, four wire service (two line, one neutral, one ground). The grounding conductor must be at
least the same gauge as the line conductors, but not less than #10 AWG. A minimum #10 AWG solid copper bond wire is also required.
Mount the subpanel in the vicinity of the spa, but not closer than five feet away, in accordance with all local codes. (N.E.C. 680-38 to 41-A-3)
INSTALLATION INSTRUCTIONS
1. To connect the electrical service, first remove the screws from the equipment compartment door. Carefully pull the door panel away and
down in order to remove it completely from the spa.
2. Locate the IQ 2020
™
spa control box. Loosen the screws on the front of the control box. Remove the screws and the control box cover.
3. Route the electrical service from the subpanel into the spa equipment compartment. Position the conduit in the recess provided between the
frame and door. Install the supply conduit so as not to block the drain valve.

E:: The subpanel must be placed in sight of the spa, at a minimum distance of five feet away.
4. Connect the supply conduit to the bottom of the IQ 2020 spa control box, using a 3/4” liquid-tight, flex conduit fittings.
GRANDEE (G), VANGUARD (V/VV), SOVEREIGN (II) & ACCOLADE WIRING CONNECTIONS
1. Identify the TB-1 terminal block, located inside the IQ 2020 control box at the lower left-hand corner.
2. Connect the #12 AWG, BLUE wire, from the subpanel 20 amp breaker, terminal L1 to TB-1, terminal 2.
3. Connect the #12 AWG, RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 4.
4. Connect the #12 AWG, WHITE wire, from the subpanel 20 amp breaker, terminal N (load neutral) to TB-1, terminal 5.

E:: The WHITE neutral wire must be attached to the LOAD neutral on the 230 volt, 20 amp breaker (not to the neutral bus bar in the subpanel).
The WHITE neutral wire coming from the breaker itself is already connected to the neutral bus bar.
5. Connect the #10 AWG, BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 1.
6. Connect the #10 AWG, RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 3.
7. Connect the #10 AWG, GREEN wire, from the subpanel GROUND bar to TB-1, system ground terminal.
8. Using the pressure wire connector provided on the outside of the control box, bond the spa to all exposed metal equipment or fixtures,
handrails, and the concrete pad (if applicable) per N.E.C. Article 680 and local codes.
9. Replace the control box cover and securely tighten the fastening screws. Close and secure the equipment compartment door.
