1. Disconnect the power cord from the house receptacle.
2. Open the equipment compartment door.
3. Remove the screws on the front of the IQ 2020
®
spa control box.
4. Open the control box cover.
5. Identify TB-1, located in the lower left-hand corner inside the control box.
6. Refer to illustration, Step 1. Remove the 2 pin jumper attached to terminals 4 and 5.
7. Refer to illustration, Step 1. Remove the wire jumper from terminals 2, and 6.
8. Refer to illustration, Step 2. Remove the power cord wires from 5, 7 and GRD (not
illustrated).
9. Unscrew the power cord strain relief and remove the power cord from the access hole in
the control box.
WARNING:
Do not allow pliers to contact any electronic components inside the control box.
Converting from 115 volts to 230 volts changes the voltage supplied to the heater from
115-volts to 230 volts. The jet pump will continue to operate at 115 volts.
InSTaLLaTIOn InSTRUCTIOnS
1. To connect the electrical service, first remove the screws from the equipment
compartment door. Carefully pull the door panel away and remove it 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 the door.
NOTE:
The subpanel must be placed in sight of the spa, at a minimum distance of 5 feet away.
4. Connect the supply conduit to the bottom of the IQ 2020 spa control box, using a minimum of 3/4” liquid-tight, flex conduit fittings.
WIRIng COnneCTIOnS
1. Identify the TB-1 terminal block, located at the lower left-hand corner of the control box.
2. Connect the #12 AWG, BLUE wire from the subpanel 20 amp breaker, terminal L1 to TB-1 terminal 5.
3. Connect the #12 AWG, 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 115 volt, 20 amp breaker (not the neutral bus bar in the subpanel).
The WHITE pigtail (neutral) wire from the 20 amp breaker 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, GREEN wire from the subpanel ground bar to TB-1 system ground terminal.
7. Bond the spa to all exposed metal equipment or fixtures, handrails, and concrete pad per N.E.C. Article 680 and all local codes.
8. Replace the control box cover and securely tighten the fastening screws. Close and secure the equipment compartment door.
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 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 (load neutral)
terminal of the 20 amp subpanel breaker. Each breaker should be tested prior to each use. Here’s how:
1. Push the “TEST” button on each GFCI breaker, and observe it click off.
2. Wait 30 seconds, then push the breaker switch to the OFF (down) position (to ensure that it has completely disengaged), then push the
breaker switch to the ON (up) position. If you don’t wait 30 seconds, the spa’s power indicator may continue to blink – try again.
If any of the GFCI breakers fails to operate in this manner, your spa may have an electrical malfunction, and you may be at risk of electrical shock.
Turn off all circuits and do not use the spa until the problem has been corrected by an authorized service agent.
