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 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 (See Figure 31)
Note: This connection must be kept dry. We recommend that a water proof junction box be used in installations
were moisture could penetrate this terminal connector.
4. Layout 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.
Note: Circuit board programming will not allow spa operation without both the temperature and high limit
sensors being properly connected to the circuit board. See Temperature and High Limit installation
instructions on the following pages to ensure proper connection prior to applying power and performing
function testing.
7. 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.
8. Once properly run through the conduit repeat Steps 5 and 6 above.

Temperature and High Limit Sensors
The temperature sensor housing is a factory installed wall fitting generally located 18“ below water level on the
front wall of the spa shell. (Near the spa light.) While the high limit sensor housing is located inside the
plumbing fitting above the heat pump.
