Insulation Test - Emerson EASYHEAT Warm Tiles Elite Mats Directives D'installation Et D'utilisation

R6. Install a fish cord through the sill plate, pull through the wall cavity
and secure in the electrical connection box. ONE ADDITIONAL FISH
CORD WILL BE REQUIRED IF THE HEATING CONTROLLER USES A
FLOOR TEMPERATURE SENSOR. (Figure R6).
Figure R6. Fish cord installation
R7. Install Power Supply Wiring in the electrical connection box, but do NOT
energize or connect to the heating controller. Install conduit, if required
(consult with your local electrical inspection authority). Multiple cable sets
may require larger boxes. Consult your local electrical authority.
INSTALLING THE WTE MAT
I1. Ensure the subfloor is clean and free of debris. Consider the
location of the electrical connection box, and the routing of the cold
lead over to the point where they will enter the wall cavity.
I2. Dry fit the WTE mat to ensure it fits the intended heated area.
I3. Insulation and resistance test

Insulation Test

To ensure that the Warm Tiles mat has not been damaged, use a
megohmmeter with one probe connected to the conductor and the
other probe connected to the ground braid. Use 500 Vdc minimum.
The megohmmeter should read min 10 Mohms.
Resistance Test
Using a calibrated digital ohm/multimeter, check the resistance of each
mat and the sensor wire before proceeding with floor finishing ensuring
no damage has occurred during installation. The resistance of the cable
in the mat should be greater than 10 ohms but less than 775 ohms. The
resistance of the sensor wire should be between 7 and 14 Kohms.
Make sure you record readings in the Mat Resistance Log attached
to this document.
NOTE: Your local electrical inspector may require inspection of the
mat installation prior to proceeding with the floor finishing.
I4. Route supply leads to electrical connection box according to the
path. Ensure leads are flat; temporarily tape down as necessary.
I5. Prepare the thinset/mortar to adhere the WTE mat to the subfloor.
Using a ¼" x ¼" square notch trowel, spread a coat of fresh thinset/
mortar over the area to be covered by the WTE mat. Make the thinset/
mortar grooves parallel to the mat wires. If laying the WTE mat in a
large area, make sure to work on one manageable section at a time.
I5. Apply thin layer of mortar to floor
I6. Place the WTE mat onto the fresh thinset/mortar pressing firmly
with a grout float or lightweight roller. Create 100% contact
between the heating mat, the thinset/mortar, and the subfloor.

Press out any air bubbles or wrinkles and ensure that the surface
is flat.
I7. To test the bond between the WTE mat and the subfloor, while the
thinset/mortar is still wet, peel a portion of the mat back from the thinset/
mortar you have adhered the subfloor. At least 80% of the underside of
the mat should be covered with thinset/mortar. Do not energize.
I8. Retest Insulation and resistance as per I3 - Insulation and
resistance test - and record readings in the Mat Resistance Log.
INSTALLING SURFACE COVERING
Tile and Stone Surfaces Covering
T1. Install WTE mat as per I1 to I8. Ensure insulation and resistance
tests have been performed and recorded.
T2. When installing a floor-sensing thermostat, position the floor-sensing
probe on top of the fabric, midway between two adjacent Heating Cable
runs but not closer than 1/2" to a heating cable (Figure T2). Please see
floor-sensing thermostat instructions for proper connection procedures.

T3. Apply a coat of thinset/mortar on top of WTE mat according to
the tile or stone manufacturer' recommended thickness. Install
tile or stone on top of the thinset/mortar. Use only cement based
self-levelling compounds. Apply the self levelling compound over
the cables and allow to cure, then proceed to install the surface
flooring. Tile must be installed according to requirements of ANSI
A108.5 or equivalent. Consult with your flooring supplier for advice.
T3. Apply thin set and install floor surface
Clean excess thinset/mortar from grout lines with a sponge or
small brush and water as tile is being laid. Do not use sharp
objects or power tools to clean grout lines, as this may damage
WTE mat.
T4. After thinset/mortar has cured, apply grout.
NOTE: Before activating the WTE mat, allow the thinset/mortar and
