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.

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 1.
panel extension loom in the
control box mounted with the
equipment pack. This extension
loom and attached black
terminal connector (see gure
at right) will be used to connect
the topside control panel to the
control box.
Connect one end of the black 2.
terminal connector to the topside
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 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 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.
