ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your Caldera 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 spa completely! Unless otherwise stipulated by your dealer, THIS IS YOUR RESPONSIBILITY.
SERVICE NOTE: All Caldera spas have diagnostic functions that are displayed on the control panel. Four flashing lines are visible on the control panel if the heater high
limit thermostat has tripped. If the four flashing lines are visible, follow the instructions in the troubleshooting section to identify and correct the cause. The four flashing
lines will stop flashing once the problem has been corrected.
CALDERA SPAS MUST BE WIRED IN ACCORDANCE WITH ALL APPLICABLE NATIONAL AND 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.
The Kauai
®
spas require a 16 amp, single phase, 230 volt, three wire service (one line, one neutral, one ground). By using a 16 amp service, the heater will not
operate whenever the jet pump is running in the high speed mode. Upgrading to a 32 amp service will allow the heater and the high speed mode of the jet pump to
run simultaneously. When upgrading the Kauai spas to a 32 amp service, jumper JP3 must be removed from the control box prior to powering up the spa
(see jumper illustration below). The Geneva

spas require a dual electrical service
using a 16 & 25 amp breaker and wired per the illustration found on the next page. Additionally, one main disconnect switch with at least 3 mm separation between
contacts must be used for all electrical circuits to the spa.
Mount the subpanel according to local codes, but not closer than 1.5 meters (5
feet) away.
CONDUIT INSTALLATION INSTRUCTIONS
1. To connect the electrical service, first remove the screws from the
equipment compartment door. Carefully pull the door panel down and away
in order to remove it completely from the spa.
2. Locate the control box. Loosen the screws on the front of the control box.
Remove the screws and the control box cover.
3. Route the electrical conduit through the access opening on either side of
the spa.
4. Connect the supply conduit to the control box and connect the wiring as
detailed on the next page and on the wiring diagram label on the inside of
the control box cover.
WARNING: Removing or bypassing any GFCI breaker 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 Caldera
spa, it is essential that you understand and apply these installation requirements.
Your Caldera 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.
