The floor must be completely swept of
all debris including all nails, dirt, wood, and
other construction debris. Make absolutely
sure there are no objects on the floor that
might damage the SunTouch wire.

Make sure all of the correct materials have
been purchased. A general list of materials
is found at the beginning of this manual.
Study the design carefully before installa-
tion. Review the thermostat location and
where the mat begins and ends, as well as the
general layout pattern.
Do not cut the wire or shorten the
mat to make it fit the space. Doing so
will cause dangerous overheating and
will void the warranty!

SunTouch can be installed in two types of
construction applications:
1. Thin-set or thick-set mortar beds (3/8"–1").
2. Self-leveling mortar beds (1/4"–1/2").
No matter the application, always install
SunTouch before installing mortar or cement.
Do not lay SunTouch in wet mortar.
We strongly recommend installing tile and
stone flooring according to manufacturer’s
recommendations, TCA guidelines, and ANSI
specifications.
If installing non-masonry floor coverings,
such as hardwood, vinyl, laminate or carpet,
follow industry and manufacturer’s recom-
mendations.
If installing non-masonry coverings, the
best method is cover the SunTouch in a self-
leveling mortar (illustrations #5 and #6).
