The hydrotherapy spa is designed to seat seven
adults. The spa holds approximately 375 gallons of
water and offers a heating system (80°F to 104°F), a
filtration system, and adjustable hydrotherapy jets.
Follow the guidelines below to use and maintain the
spa for your long-term enjoyment.
WIRING THE HYDROTHERAPY SPA
The hydrotherapy spa is designed to operate with a
240 volt AC power source. It must be wired directly
into a grounded circuit with a Ground Fault Circuit
Interrupter (GFCI) capable of carrying 45 amps. No
other appliance should be on the same circuit. Test
the GFCI before connecting the power cord to the
spa. Connection of the spa to the 240 volt power
source must be performed by a qualified, licensed
electrician and must comply with all local, state,
and federal electrical codes. Please refer to the
instructions on the inside of the controller for informa-
tion about connecting the spa to a 240 volt power
source.
Once the spa is filled with water, the power can be
turned on. Note: If this is the first time the spa has
been turned on, or if the pumps have been
drained, the pumps must be primed before the
spa can be used.
PRIMING THE PUMPS
To prime the pumps, follow the steps below.
1. Remove the access panel (see ATTACHING AND
REMOVING THE ACCESS PANEL on page 17).
2. Make sure all of the valves in the plumbing system
are open to allow as much air as possible to
escape from the plumbing and the controller dur-
ing the filling process. Fill the spa to the level
shown in step 5 on page 9. Use towels to soak up
any water that leaks from the plumbing and pumps
during the priming process.
3. Loosen the indi-
cated collar on
one of the pumps
to vent the air
from the pump.
Repeat for the
other pump.
Allow a small
amount of water
and air to escape from the pumps and related
plumbing. Then, retighten the collars.
4. Turn the power on. The spa will begin an auto-
matic priming sequence.
A countdown from “005” to “000” will appear in the
display of the console.
Once the countdown has reached “000,” “Pr” will
be displayed. “Pr” indicates that the controller is in
the two-pump priming mode. This mode will last
for four to five minutes.
5. As soon as “Pr” is displayed, push pump button 1
once to start the pump on low speed and then
push the button again to switch to high speed.
Repeat for pump button 2.
If water is not flowing from the jets after two min-
utes, turn the power off. Important: Do not allow
the pumps to run without priming for more than
two minutes. Under no circumstances allow a
pump to run without priming beyond the end
of the four to five minute priming mode. Doing
so may cause damage to the pump and cause the
spa to go into an overheat condition.
Repeat the process of venting the air from the
pumps and the controller and priming the pumps
until water flows from the jets.
6. When the priming sequence is completed, the spa
will automatically return to the normal heating and
filtering mode. During the priming process, the
heater is disabled to allow the pumps to be primed
without activating the heater under low flow or no
flow conditions.
Once the pumps are primed, push pump button 1
and pump button 2 to turn the pumps off.
7. The console will display “100F” and then “--F,” for
approximately one minute. The spa requires one
minute of water flowing through the heater to
determine the water temperature.
