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.

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 identication 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 briey 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 veried. 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.
