T8-S / T8-X Topside Installation

Topside Installation Preparation

The T8-S / T8-X topside control requires three 2-1/4” holes to be cut out
of the shell of the hot tub it is to be installed into. Using a 2-1/4” hole saw,
three holes will need to be drilled in a straight line, with the center of each
hole spaced 1-5/8” from the center of the previous hole, as shown:

Approx. 6-3/8” (~161 mm)

2-1/4” Hole

1-5/8” 1-5/8”

2-1/4” Hole 2-1/4” Hole

Topside Control Installation

Once ready to install, plug one end of the topside cable into the back of the
T8 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.

Approx. 3-3/8” (83.5 mm)

NOTE: Do NOT connect/disconnect the T8-S/T8-X topside while the
control box is powered. Always make sure the power is shut off at the
breaker before removing/installing a topside, as to avoid damaging the
electronics.
