2008 Inground Spa Owner’s Manual
LTR20081002, Rev. A
Preparing for Your New Inground Spa
PVC plumbing is acceptable when properly buried in
trenches.
Most water plumbing lines are 2” or larger and must be
schedule 40 or heavier PVC. When plumbing, minimize
the use of 90˚ elbows as much as possible. The use of
45 ˚ elbows will increase the amount of jet pressure you
will have over the use of 90˚ elbows.
The plumbing on the spa shell is labeled by the factory
in the following manner:
Pump 1 Suction
: 2” line that connects the spa filter and
bottom drain assembly to the front of pump 1.
Pump 1 Return: 2” line that connects the top of pump 1,
through the equipment filter and heater back to selected
jets in the spa.
Pump 2 Suction
: 2” line that connects the spa filter and
bottom drain assembly to the front of pump 2.
Pump 2 Return: 2” line that connects the top of pump 2
back to selected jets in the spa.
Ozone Line
: 1” line that connects to a 1” flexible line
extending off the bottom of the equipment pack filter
canister through an ozone injector (If ozone equipped)
and connected to ozone port on the spa.
Air Blower: 1 1/2” line that is plumbed out of the air blower
(located on the equipment pack) and extended up 18”
above the spas water level to prevent water flooding the
air blower.
Air Venturi: 1/2” line that is plumbed 18” above the spa’s
water level.
Topside Control Panel and Temp Sensor: 1” line that
connects to the bottom of the control box located on the
equipment pack.
Electrical and Electronic
Connection
Remote Equipment Topside Control Panel
The next few steps to complete the installation should
be performed along with installation of the temperature
sensor and 12V spa light wiring (if applicable). All of
these components are generally installed using the
same conduit.
Locate the topside control panel extension loom in
the control box mounted with the equipment pack.
This extension loom and attached black terminal
connector (see figure at right) will be used to connect
the topside control panel to the control box.
1.
Connect one end of the black terminal connector to
the topside control panel cable.
Connect the other end of the terminal connector to
the extension loom.
NOTE: This connection must be kept dry. We recommend
that a waterproof junction box be used in installations
where moisture could penetrate this terminal connector.
Lay out the extension loom to verify that you have
enough length to reach the control box. Remember
that conduit runs are not generally run in a straight
line. Every bend, and up and down run consumes
line length. Take this into consideration when
verifying electrical and plumbing runs.
Connect the extension loom to the control panel
location on the circuit board located inside the
control box. You will also need to connect both the
temperature and high limit sensors to the circuit
board prior to testing. (See the temperature and
high limit installation instruction on the next page
for proper identification and see the wiring diagram
on the inside cover of the control box for proper
placement.)
Turn on the power supply to the spa equipment and
briefly test all functions on the topside control panel
to verify that both connections and extension loom
are in working order before proceeding with the
installation.
NOTE: Circuit board programming will not allow spa
operation without both the temperature and high limit
sensors being properly connected to the circuit board.
Once topside panel operation is verified. Turn off
power, disconnect the extension loom from the
circuit board and GENTLY route through conduit to
complete installation.
NOTE: This loom and its connector are not meant to
withstand heavy pulling. Make sure, when routing the
extension loom and temperature sensor lines through
conduit, you exercise extreme caution.
Once properly run through the conduit, repeat steps 5
and 6 above.
In-Ground Spa Light Installation
Instructions
On spas ordered with in-ground lights, the factory installs
the light niche for you. The next steps of installation
should be performed by a qualified licensed electrician.
Always read and follow light manufacturer’s safety and
installation instructions prior to installation and operation.
