IMPORTANT: Fill the spa with water before turning on the power.
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!
All HOT SPRING spa models, 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.
230 VOLT PERMANENTLY
CONNECTED MODELS
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.
The two diagrams on the following page illustrates how to wire
specific spa models:
• An electrical subpanel containing two GFCI breakers is included with
each 230 volt spa. We recommend that this subpanel be used to
supply power to the spa.

Electrical Requirements

eQuIrementS
• The 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)
• Open Spa using Door Removal Instructions found on page 30.
• Insert power wires into spa from either side towards the bottom front,
you will find a plastic cap attached to fitting.
• Once your spa has been filled with water, turn it on and test all of the
circuit breakers.
IMPORTANT: If both breakers immediately trip, verify that the wires are
correctly connected. 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.
WARNING: Removing, or bypassing any GFCI breaker will result
in an unsafe spa and will void the spa's warranty.
