Electrical Requirements And Precautions; Volt Permanently Connected Models - HotSpring Landmark Owner's Manual

ELECTRICAL REQUIREMENTS AND
PRECAUTIONS
Y our Hot Spring
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
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 PERMANENTLY CONNECTED MODELS

HOT SPRING
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 be at least the same gauge as the line conductors, but not less than #10 AWG. A minimum
#10 AWG solid copper bond wire is also required.
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
1. To connect the electrical service, first remove the screws from the equipment compartment door. Carefully pull the
door panel away and down in order to remove it completely from the spa.
2. Locate the IQ 2020
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 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.
4. Connect the supply conduit to the bottom of the IQ 2020
conduit fittings.
WIRING CONNECTIONS
1. Identify the TB-1 terminal block, located inside the IQ 2020
2. Connect the #12 AWG, BLUE wire, from the subpanel 20 amp breaker, terminal L1 to TB-1, terminal 2.
3. Connect the #12 AWG, RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 4.
4. Connect the #12 AWG, WHITE wire, from the subpanel 20 amp breaker, terminal N (load neutral) to TB-1, terminal 5.
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.
5. Connect the #10 AWG, BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 1.
6. Connect the #10 AWG, RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 3.
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 spa to all exposed metal
equipment or fixtures, handrails, and the concrete pad (if applicable) per N.E.C. Article 680 and local codes.
