ELECTRICAL REQUIREMENTS
AND PRECAUTIONS
Your Limelight
™
hot tub has been carefully designed to give you maximum safety against electric shock. Connecting the hot tub to an improperly
wired circuit will negate many of the hot tub’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 hot tub model completely!
SERVICE NOTE: The Limelight hot tub is equipped with a power indicator which, in addition to showing the hot tub 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.
230 VOLT CONNECTED
Electrical Requirements
LIMELIGHT HOT TUB 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 hot tub. We recommend that this subpanel be used to supply
power and protect the hot tub.
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 #8 AWG.
Mount the subpanel in the vicinity of the hot tub, 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 panel. Carefully pull the door panel away and
down in order to remove it completely from the hot tub.
2. Locate the IQ 2020
®
hot tub 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 hot tub equipment compartment.
NOTE:
The subpanel must be placed in sight of the hot tub, at a minimum distance of five feet away.
4. Connect the supply conduit to the bottom of the IQ 2020 hot tub control box, using a 3/4” liquid-tight, flex conduit fittings.
WIRING CONNECTIONS
1. Identify the TB-1 terminal block, located inside the 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 1.
3. Connect the #12 AWG, RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 3.
NOTE
: The WHITE neutral wire must be attached to the LOAD neutral on the 230 volt, 30 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.
4. Connect the #10 AWG, BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 2.
5. Connect the #10 AWG, RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 4.
6. Connect the #10 AWG, WHITE wire, from the subpanel 30 amp breaker, terminal N (load neutral) to TB-1, terminal 5.
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 hot tub to all exposed metal equipment or fixtures,
handrails, and the concrete pad (if applicable) per N.E.C. and local codes.
9. Replace the control box cover and securely tighten the fastening screws. Close and secure the equipment compartment panel as follows:
• Place top of panel directly below bartop against the frame of the hot tub.
• Push bottom of panel against the hot tub frame.
• Slide panel upward until screw holes line up.
• Slightly pull on panel, if door remains against the hot tub then replace the screws.
WARNING: FILL THE HOT TUB WITH WATER BEFORE TURNING ON THE POWER! (See STARTUP AND REFILL PROCEDURES).
Once your hot tub has been filled with water, turn it on and test all of the circuit breakers.
