T7 Topside Installation

6

Topside Installation Preparation

The T7 topside control requires a 1.75” hole in the shell of the hot tub to
be installed. If you don’t already have a hole that is 1.75” in diameter, you
can use a 1.75” (1 3/4”) hole saw to make the hole needed for installation.
Simply drill the hole in the center of where you’ll be installing the topside.

Topside Installation Location

The T7 topside should be installed on an outward facing edge of the hot
tub, so that it is not subject to trapped steam and moisture under the cover.
Failure to do so may result in the need to prematurely replace the graphic
decal assembly on the face of the topside control.

About The T7 Topside

7

Topside Control Installation

Once ready to install, plug one end of the topside cable into the back of the
T7 topside control, and snake the topside cable through the cutout in the
spa’s shell and down to the control box. Then plug the opposite end of the
topside cable into the topside receptacle on the control box.

Simply affi x the topside to the hot tub by peeling off the paper over the
adhesive back of the topside and press it fi rmly into place, slowly pressing
all around the perimeter of the topside fi rmly to assure a fi rm bond.

NOTE: Do NOT connect/disconnect the T7 topside while the control box
has power going to it. Always make sure the power is shut off at the breaker

before removing/installing a topside, as to avoid damaging the electronics.

Spa-Touch™ Technology

The T7 topside uses United Spas’ patent pending Spa-Touch™ technology.
This hybrid switching technology marries the satisfaction of having a
physical button to press, with the longevity and reliability of touch-panel
switching system with no moving parts to break down over time.

If your button presses are not registering, make sure that you are pushing
the raised buttons completely fl at against the panel, and that you are
waiting a second between button presses.
