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!
SERVICE NOTE: All Hot Spring spa model's, except Custom Cabinet models (CC), are equipped with a power indicator (Hot Spring
Logo blue light) 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. The Power and Ready indicator
lights on the control panel also provide the same diagnostic function.

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 not be less than #10 AWG. Refer to local codes and to NEC 250-122 (table).
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
To connect the electrical service, first detach the equipment compartment door as follows:1.
Remove the 6 door panel screws, then remove door.•
Locate the IQ 2020 2.
®
spa control box. Loosen the 2 screws on the front of the control box. Remove the screws and the control box cover.
Route the electrical service from the subpanel into the spa equipment compartment
3. using one of the knockouts provided. Position
the conduit in the recess provided between the frame and door. Install the supply conduit so as not to block the drain valve.
NOTE: The subpanel must be placed in sight of the spa, at a minimum distance of five feet away.
Connect the supply conduit to the bottom of the IQ 2020 spa control box, using a 3/4” liquid-tight, flex conduit fittings.4.
VANGUARD (VV) & SOVEREIGN (II) WIRING CONNECTIONS
Identify the TB-1 terminal block, located inside the IQ 2020 control box at the lower left-hand corner.1.
Connect the #12 AWG, 2. BLUE wire, from the subpanel 20 amp breaker, terminal L1 to TB-1, terminal 5.
Connect the #12 AWG,
3. RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 6.
Connect the #12 AWG,
4. WHITE wire, from the subpanel 20 amp breaker, terminal N (load neutral) to TB-1, terminal 7.
NOTE: 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.
Connect the #10 AWG,
5. BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 2.
Connect the #10 AWG,
6. RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 4.
Connect the #10 AWG,
7. GREEN wire, from the subpanel GROUND bar to TB-1, system ground terminal.
Using the pressure wire connector provided on the outside of the control box, bond the spa to all exposed metal equipment or fixtures,
8.
handrails, and the concrete pad (if applicable) per N.E.C. Article 680 and local codes.
Replace the control box cover and securely tighten the fastening screws. To replace equipment compartment door, place panel
9.
under bar top first. Push bottom of door panel towards spa making sure all 3 snaps are fastened into spa frame.
WARNING: FILL THE SPA WITH WATER BEFORE TURNING ON THE POWER.
Once your spa has been filled with water, turn it on and test all of the circuit breakers.
NOTE: If both breakers immediately trip, verify that the #12 AWG WHITE neutral wire is connected from TB-1 terminal 7 to the N (load
neutral) terminal of the 20 amp subpanel breaker. Each breaker should be tested prior to each use. Here’s how:
