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 bot-
tom of the control box located on the equipment pack.

The next few steps to complete the installation should be performed along
with installation of the temperature sensor and 12V spa light wiring (if ap-
plicable). All of these components are generally installed using the same
conduit.
Locate the topside control panel 1.
extension loom in the control
box mounted with the equip-
ment pack. This extension loom
and attached black terminal
connector (see gure at right)
will be used to connect the top-
side control panel to the control
box.
Connect one end of the black 2.
terminal connector to the top-
side control panel cable.
Connect the other end of the terminal connector to the extension 3.
loom.
NOTE: This connection must be kept dry. We recommend that a water-
proof 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 4.
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 5.
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 identication 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 briey test all 6.
functions on the topside control panel to verify that both connections
and extension loom are in working order before proceeding with the
installation.
