1. Measure floor area to be heated & determine square footage of
heatmat needed. Order the correct size. Do not install heatmat
under any fixed furniture. (eg: vanity units)
2. Be sure to leave area close to toilet flange free of heating cables
(6” radius).
3. Pay close attention to heating high trac areas (in front of
shower, tub, toilet room, vanity) and leave areas close to walls, &
behind doors unheated if needed.
1. The yellow heating cable must NEVER cross at any point—this
includes the thermostat sensor probe wire.
2. The simplest way is to run the heatmat the length of the room.
Check the room width in multiples of 20”. For example, if a
room is 64” wide, you will have room for 3 runs of heatmat with
2” at either wall.
3. Make sure the thermostat floor sensor is able to be installed
midway between 2 heating cables without crossing them.
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.
This number can be calculated by the following formula:
Factory cable tag reading (F) X .95 and (F) X 1.05
The OHM reading should be between these 2 numbers.
Example: Factory cable tag reading of 17.3. The allowable OHM
range for this heatmat would be: 17.3 X .95 = 16.4 and 17.3
X 1.05 = 18.1 This mat will need to read between 16.4 and 18.1
throughout the installation process.
NOTE: All measurements will need to be recorded and submitted
to www.icobath.com/cosyfloor-warranty
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.
4. Record these readings along with heatmat serial number, date and factory readings on the warranty
application at www.icobath.com/cosyfloor-warranty.
