6. HEATMAT INSTALLATION
7. FLOOR SENSOR INSTALLATION
8. RESISTANCE TEST(during installation)
1. Check that you have received heatmat, fixing strips, tape, circuit
fault detector, thermostat and floor sensor.
2. Using pull wire provided in conduit, feed the black cable leads
up into the electrical junction box.
3. Leave all cable tags on cable lead and ensure they remain in
electrical junction box.
4. Connect provided circuit fault detector to cable lead ends.
5. Chisel a channel in subfloor to recess the cold lead and heating
cable splice.
6. Starting at one side of the room, roll out the heatmat. When
needed, simply cut the blue mesh only, turn the heatmat 180
degrees and continue rolling down the length of the room. The
heating cables should never be closer than 2”.
7. When fitting around irregular shapes, simply remove mesh from
the heating cables and secure the heating cables to sub floor
with tape. Take care not to damage the heatmat while removing
cables. Ensure that the cables do not cross & the spacing is not
closer than 2”.
8. Ensure the black cable lead (coming from conduit) is firmly
fastened to the subfloor.
9. NEVER ALLOW YELLOW HEATING CABLE TO GO UP WALL
OR INTO CONDUIT.
1. Position end of sensor probe in the exact center between 2
heating cables.
2. Fasten floor sensor with tape provided as needed.
3. Feed floor sensor wire up wall to thermostat location.
1. Using a digital OHM meter, measure the resistance between the
power leads. (insulated wires) This reading should be within 5%
of the OHM reading on the cable tag. Use formula in section 5
“Resistance test”.
2. Using the digital OHM meter, measure the resistance between the
Ground (un-insulated) cable and each of the power (insulated)
leads. This should have no reading or .OL. (open load). If you have
an OHM reading at this point STOP AND DO NOT CONTINUE WITH
INSTALLATION.
3. Measure OHM reading for thermostat floor sensor & ensure this
reading is within the guidelines stated on the floor sensor cable tag. Again, use same formula as in steps
5 & 8.
4. Record these readings along with heatmat serial number, date and factory readings on the warranty
application at www.icobath.com/cosyfloor-warranty.
• NEVER use nails or cable
fasteners to hold wires in place
• Use silicone caulking to seal
any gaps around perimeter
of the room. This will prevent
self-leveling concrete from
escaping. 2” masking tape
also works well. Use masking
tape to build dams at floor
vents, doorways, or any other
areas of loss.
• Document all phases of
installation with pictures.

Ensure the sensor probe will not be in an area covered by a
bathmat or area rug-these will trap the heat & give a false
reading, causing the heating system to shut o prematurely.
