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.
1.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.
2.Connect one end of the black terminal connector to the topside control panel cable.
3.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.
4.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.
5.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.)
6.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.
