Manual

STEP 2.1
Select Type of Construction
Choose the best thin-set, thick-set, or self-
leveling mortar installation detail for your
application. Consult with building profession-
als and/or SunTouch personnel for specific
details concerning proper installation.
STEP 2.2
Floor Preparation
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.
STEP 2.3
Study the Factory-supplied
Items and the Design
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 instal-
lation. 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!
STEP 2.4
Mortar and Thin-Slab Applications
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).
