Dear Customer!
You have purchased a IWARM floor heating system.
Thank you for your choice. We are sure that our product
will meet all your expectations and bring warmth and
comfort in your home.
Please read the following advices carefully before
installing the system:
JWe recommend you to buy an IWARM Additional Kit
with a thermostat, temperature gage, protective cor
rugated tube for the temperature gage, and a service
box. This will ensure reliable operation of your IWARM
floor heating system.
Jmake sure that your floor area corresponds to the effi
ciency of the system you bought. Advices on how to
choose your system and recommendation for heating
cable spacing are given in the Appendix to this
instruction. Adhere to the recommended spacing
when weaving the cable. Do not allow it to approach
together closer than 60 mm.
Jbefore installing the system make sure it is suitable for
your floor finishing. IWARM system is intended for
floors with ceramic or stone tiles or into grout.
Jplan the installation of your heating cable so that it will
not be damaged during subsequent works.
Jif you do not want to apply tile immediately after your
heating system has been installed, make sure that

your heating elements will not be damaged during this
time (e.g. cover the elements with cardboard or ply
wood sheets).
Jwe recommend you to use only grades of mixtures
which allow for floor heating.
Jmake sure the element heats before any tiling works
(according to instructions in paragraph 5, pages
19–20, 25).
Jtake care not to displace or damage the cable when
applying tiles.
Jread carefully the restrictions on heating system

3. System delivery kit
IWARM floor heating system consists of a reel of
heating cable element and assembly tape. A thermostat
is necessary for the reliable operation of IWARM floor
heating system. We also recommend you to buy an
I-WARM Additional Kit with a thermostat, temperature
probe, protective corrugated tube for the temperature
probe, and a service box.
Heating section (IWARM heating system) as well as a
thermostat and a service box (IWARM Additional Kit)
have certificates with their specifications and warranties.
3.1. Heating section
Heating section is a heating cable of a sertain length
with 3 m long installation cable. Connection of the heat
ing cable and installation cable, as well as terminal seal
ing are made in enclosed splicing and terminal cou
plings. These boxes are highly reliable. They are repeat
edly tested at the factory.
Sections with different nominal power have different
colors and marking to facilitate their distinguishing.
Sections specifications and wiring diagrams are given in
the Appendix to these instructions.
Heating cables of heating sections are made and test
ed according to high reliability technology. Heating sec
tions approved by Russian Compliance Certificates, Fire
Safety Certificates and Hygiene Certificate.

Cable insulation is made of tough, heatresisting, non
flammable Tefzel fluoropolymer. Cable shield is made of
aluminum foil reinforced with copper line. The shield pro
vides mechanical and electrical protection and increases
heat resistance of the cable. Cable jacket is made of
heatresistant, hard PVC.
Heating cables are made of highquality materials by
leading polymer producers.
Doubleconductor cable makes it possible to feed the
section from one end only. This facilitates section laying
out in the room.
To connect IWARM section properly pay atten
tion to installation wire coloring.
Blue and brown wires go to the heating wires and are
connected to the thermostat.
Plain conductor with twisted copper wires is connect
ed with the protective shield of the cable. This conductor
has to be connected to the building grounding loop (or
neutral conductor).

3.2. Prepunched band installation
Prepunched band installation is used to facilitate
heating sections laying out and fixing to the floor sur
face. Pieces of tape are fixed to the subfloor. The tape
has equally spaced fixing lugs to assure equal element
spacing.
3.3. Thermostats
A thermostat allows for energy saving, turning on only
when the thermal comfort in the room needs to be sus
tained.
With programmable thermostats you can set your own
temperature schedule for a day or a week. We recommend
you to use new IWARM series thermostats.
3.4. Service box
The service box is used to appliance cords when sev
eral heating sections are installed, as well as to facilitate
sensor of temperature replacement in case of its defect.
Connections are made in twopart terminal blocks.

4. Preparation for Installation
4.1. Floor Preparation
To provide long service life of the floor heating system
and to eliminate possible damages to the heating cable
during installation works you need to do some preparato
ry works.
How to prepare the surfaces to lay out the heating
cable is described below.
JConcrete floor: provide smooth, clean and dry sur
face (preliminary level uneven floor surface with any
smoothing mixture). Use primer to get better floor sur
face. Wait for the floor to dry after the surface treat
ment (according to the instructions for use).

It is recommended to apply primer
to the surface
The floor surface should be
smooth, clean and dry
JCeramic floor tiles: provide clean, dry and smooth
surface without sharp edges, irregularities and so on.
JWooden floor: Secure the floor planks, cover with
waterproof plywood sheets 18 mm in thickness or any
other similar material sheets and fix them with screws
to provide reliable and stable base. It is not recom
mended to put plywood sheets onto beams or joists
such base will not have necessary mechanical
strength. Strong base is important to prevent cracks in
the mortar or adhesive mixture. Sharp edges of these
cracks can damage the heating cable.
JFloor with finishing: previous floor finishing (e.g.
laminates, cork and so on) shall be removed together
with the adhesive layer.
JFinishing (tarbitumen mixture) used as water
proofing: shall be covered with no less that 50 mm
screed. Put the heating cable onto dry screed (screed
drying time is 28 days). Consult the manufacturer if
you use any other waterproofing finishing. We recom
mend you to use high quality mixtures with polymer
plastic additives.
