Position the power leads near the thermo-
stat. If this is not possible, then route the
power lead through a wall and/or floor over to
the location of the thermostat (follow all elec-
trical/building codes using electrical conduit
and boxes).
In all applications, double-sided tape can
be used to affix SunTouch to the substrate.
However, if installing SunTouch over backer
board or plywood, pneumatic stapling can
be faster.
Begin the installation by rolling out the mat
according to the plan. At each turn or bend,
stop and stretch the mat tightly to pull out the
slack. Then affix the mat to the floor using
double-sided tape or staples.
When using double-sided tape, apply it to
the floor on 2' centers, or more, as necessary,
depending on jobsite conditions. The tighter
the mat, the simpler the thin-setting will be.
The floor must be clear of debris for the tape
to stick. Firmly rub the white, paper side of the
tape before pulling off the paper. This will
ensure a strong bond between the tape and the
floor. Cover approximately 10 sq.ft. at a time.
Use short pieces as necessary at the corners.
When using pneumatic staples, we recom-
mend 3/8" x 1/4" chisel point staples. Initially
attach the SunTouch mat every 2' to 3' on
either side of the mat in the “valleys” between
the blue heating wires as shown at left. By
doing so it will be easier to pull up the mat and
reposition, if necessary. When satisfied with
the layout, go back and staple on 1' centers at
either side in the “valleys” between the wires.
Proceed slowly and be very careful not to
staple the blue heating wire.
Cut or remove the orange weave as neces-
sary to make turns. Do not tack or staple the
blue heating wire. Install the SunTouch
approximately 4"–6" away from walls, show-
ers, tubs, toilets, drains, etc., as shown in this
section and the Appendix. Install in-line with
vanity and counter areas. This is because you
want to make sure to get heat right up to the
face of the cabinet so that toes are kept warm.
Install roughly 18"–20" from back wall in
toilet area. See page 9 for details.
Do not leave gaps between the mats. The
heat will conduct only 1"–2" from the heating
wire. SunTouch should be installed continu-
ously across the floor as shown in the dia-
grams in this manual. Never install mats in a
fashion causing the blue heating wires to be
any closer than 2" from each other.

SunTouch can be installed in shower areas,
but there are several precautions that must be
observed (see pg. 13 for more details).
1. Never install SunTouch in shower walls
(or any other wall).
2. Never make a field splice to mats
installed in shower. Do not attempt to repair
or modify the mat in any way; serious hazard
could result.
3. Embed mats in mortar and install only
under tile, stone, brick, or other masonry sur-
face, per this instruction manual.
4. Never begin the mat in the shower. The
connection between the power lead and the
blue heating wire must be fully embedded in
mortar and located at least 1' away from
shower openings and other areas normally
exposed to water.
5. Mat controls must be located at least 4'
away from shower openings such that they
cannot be exposed to water or touched by a
person in the shower area.

The power lead
is thicker than the SunTouch mat. If thin-
setting over backer board or slab, chisel or saw
a groove to recess the power lead to the level
of the SunTouch. Use hot glue to secure the
power lead in the groove. Or end the power
lead at the floor and run just the heating wire
to the beginning of the mat. Do not damage
the power lead — electrical shock could
result when the mat is energized.

Depending on the thickness of the mortar bed,
you may need to chisel under the factory
connection in order to recess the connection.
Be extremely careful not to damage the blue
heating wire or connection. A dab of hot glue
will hold the connection in place.

A sensor should be installed in the floor
and routed up the wall as described in Step
1.4. Simply tuck it under the mat or weave it
in between two heating wires. The sensor
should extend approximately 6"–12" into the
mat as shown on page 10. Be careful not to
locate the sensor near other heating sources
such as a heating duct below the floor.
