Remote Equipment Topside Control
Panel
The next few steps to complete the installation should
be performed along with installation of the tempera-
ture 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 1.
in the control box mounted with the equipment
pack. This extension loom and attached black ter-
minal connector (see gure at right) will be used
to connect the topside control panel to the control
box.
Connect one end of the black terminal connector 2.
to the topside control panel cable.
Connect the other end of the terminal connector 3.
to the extension loom.
NOTE: This connection must be kept dry. We recom-
mend that a waterproof junction box be used in instal-
lations where moisture could penetrate this terminal
connector.
Lay out the extension loom to verify that you have 4.
enough length to reach the control box. Remem-
ber 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.
Electrical and Electronic Connection
Connect the extension loom to the control panel 5.
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 cir-
cuit 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 6.
and briey test all functions on the topside control
panel to verify that both connections and exten-
sion 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 veried. Turn off 7.
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.
