The SunStat is approved for use in U.S. and Canada, separate from the
SunTouchListedassembly.
NEVER install SunTouch under carpet, wood, vinyl, or other
non-masonry flooring without embedding it in thin-set,
thick-set, or self-leveling mortar.
NEVER install SunTouch in adhesives or glues intended for
vinyl tile or other laminate flooring. It must be embedded in
cement-based ceramic tile mortar.
NEVER cut the heating wire.
NEVER bang a trowel on the mat or heating wire to remove excess
mortar from it.
NEVER cut the mats to make them shorter. Only the fiber mesh
can be cut to make turns or to help make the mat fit a par-
ticular area.
NEVER attempt to repair the heating wire if it is damaged. Call the
factory for instructions before proceeding.
NEVER splice one mat heating wire to another mat heating wire to
make a longer mat. Multiple mats must be connected in paral-
lel directly to power in a junction box or to the control.
NEVER install one mat on top of another or overlap the mat on
itself. This will cause dangerous overheating.
NEVER forget to install the floor sensor.
NEVER install SunTouch in any walls.
NEVER install mats under cabinets or other built-ins, or in small
closets. Excessive heat will build up in these small spaces,
and the mat can be damaged by fasteners (nails, screws, etc.)
used to install built-ins.
NEVER remove the nameplate label from the power leads.
ALWAYS completely embed the heating wire and factory connec-
tion in mortar.
ALWAYS enter mat and sensor resistance readings in the Mat and
SensorResistanceLog(page4)before,during,andafterthe
installation process.
ALWAYS pay close attention to voltage and amperage require-
ments of the breaker, the control, and the SunTouch mat.
For instance, do not supply 240 VAC power to 120-VAC
SunTouch mats or controls.
ALWAYS make sure all electrical work is done by qualified per-
sons in accordance with local building and electrical codes,
Section 62 of the Canadian Electrical Code (CEC) Part I, and
the National Electrical Code (NEC), especially Article 424,
Part IX of the NEC, ANSI/NFPA 70, and Section 62 of CEC
Part I.
ALWAYS use copper only as supply conductors.
ALWAYS affix the warning label (included with this manual) to
the control cover plate or other location where it will be
easily noticed.
ALWAYS seek help if a problem arises. If ever in doubt about
the correct installation procedure to follow, or if the product
appears to be damaged, the factory must be called before
proceeding with the installation.

DesignDepartmentat 888-432-8932 if there are any questions or
problems regarding the installation of the mat or its related elec-
trical components.
