NEVER CONNECT THE SPA TO AN EXTENSION CORD!
A pressure wire connector is provided on the exterior surface of the control box, inside the spa. This is to permit the connection of a
ground bonding wire between this point and any metal equipment, enclosures, reinforced concrete pad, pipe, or conduit within 5 feet of
the spa (if needed to comply with local building code requirements). The bonding wire must be at least a #10-AWG solid copper wire.
Bond the spa to all exposed metal equipment or fixtures, handrails, and concrete pad per N.E.C. Article 680 and all local codes.
INSTALLATION INSTRUCTIONS
All 115 volt Hot Spring
®
spa models come equipped with approximately 15 feet of
useable power cord (this is the maximum length allowed by Underwriters Laboratory and
the National Electric Code). When the spa is installed, the power cord will come out of
the bottom of the equipment compartment door. For your safety, when the electrician is
installing the 20 amp single electrical outlet and waterproof cover, the outlet should be no
closer than 5 feet (1.5 meters) and no farther than 10 feet from the spa [reference National
Electrical Code 680-6a(1) and 680-41a].
The Ground Fault Circuit Interrupter (GFCI) is located at the end of the power cord. This device
is for your protection. It is very important to protect it from rain and other moisture. Test once a
month, with the plug connected to the power supply,
1. Push the “TEST” button on the GFCI breaker. The spa should stop operating and the GFCI power
indicator will go out.
2. Wait 30 seconds, then push the “RESET” button. Power will be restored to the spa and the GFCI
power indicator will turn on.
If the GFCI fails to operate in this manner, your spa may have an electrical malfunction, and you
may be risking electrical shock. Turn off all circuits and do not use the spa until the problem has
been corrected by an authorized service agent.
WARNING: Removal of the GFCI from the spa’s power cord will result in an unsafe spa and will
void the spa’s warranty.
IMPORTANT: Should you ever find the need to move or relocate your Hot Spring
®
spa, it is essential that you understand and apply
these installation requirements. Your Hot Spring spa has been carefully engineered to provide maximum safety against electric shock.
Remember, connecting the spa to an improperly wired circuit will negate many of its safety features.
NOTE: Long wiring runs may require larger-gauge wire than stated. We recommend using a maximum 3% voltage drop when
calculating wire gauge requirements.
230 VOLT CONVERSION INSTRUCTIONS
Refer to the following instructions to convert a 115 volt spa to a 230 volt spa.
NOTE: Converting the spa to 230 volt operation should only be done by an authorized
service agent or a qualified electrician.
Required Part: A Subpanel (230 volt Convertable).
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.
Electrical Requirements
Remove the Terminal Block Power Jumper
using needlenose pliers From terminal 4-5.
Remove wire jumper from 2 & 6.
Remove the three power cord wires from
terminal block 5,7 and GRD. Leave Terminal
Block Power Jumper 6-7 in place.
