For a good adhesion of the film to the surface of the screed, it is recommended that the floor surface be primed. The better the floor is prepared, the better will be the adhesion of the film and the screeds and the tiles will be more securely fixed.

Priming requires a site on which the film will be placed with a margin of 10 cm around the perimeter.

Placing and cutting the film is carried out on the planned surface and fixed with tape. The film is placed with the logo upward, so that the text is read.

The maximum permissible length of one strip of a meter-wide film of standard power in 220 W is 6 meters. This length is dictated by the maximum load on the copper film of the film.

Films can be stacked back to back or at a distance from each other.
Imposition of films is not allowed.
It is not recommended to lay under stationary furniture, which closes the heat dissipation.

For use under ceramic coatings for screed mounting, the Heat Plus Premium Gold infrared film is optimally suited. This film not only fully meets the requirements for mechanical strength and temperature loads for use under ceramic coatings for mounting on the screed under adhesive formulations, but also has an enhanced ionizing effect due to the gilded coating.

You can also use Heath Plus Premium Silver film - it is a simplified analogue of the Gold film (does not have an enhanced ionizing effect).

To control the temperature and connect the film to the network, a thermostat is used. At this stage, it is necessary to prepare the location of the thermostat on the wall

It is recommended to place the thermostat in the vicinity of the existing wiring or outlet for easy connection. Since the length of the wire of the remote temperature sensor is 2-3 meters - the thermostat should be placed at a height of up to 1.5 meters from the floor.

Depending on the type of the thermostat, the installation can be carried out either in a junction box (undercutter - internal installation) or simply with bolts (on the mounting plate - external installation).

To control the heating system, it is recommended to use temperature controllers with the possibility of programming. This function of the thermostat allows you to reduce the cost of the heating system by controlling the temperature in time: turning off the film at a time when there is no need for heating and the system is activated in advance before the people arrive in the heated room.

To connect the film to the thermoregulator and the network, it is necessary to create places for electrical contact. For this, special clip-connectors are used. They are mounted on a copper bus and crimped using a hand press or pliers.

When installing the clip, it is necessary to slightly layer the film in the area of ​​the copper bus (use a knife to press the film). One blade of the clip is installed inside the film on the copper bus. The second blade blades the film from above to fix the clip.

To simplify the subsequent connection of the connector to the wires, the clip must be installed perpendicularly to the end of the film with the hook upwards.

Another option for creating an electrical contact is soldering the wire to the copper film of the film.

Wires are connected to the film by means of clips or by soldering.

It is necessary to clean the wire from insulation with a stripper or other tool.

For connection with clips, it is necessary to make a loop around the hook of the clip and clamp it with a hand press.

To connect wires by soldering, it is necessary to carefully remove the layer of lamination over the copper bus with a soldering iron and a knife, without damaging the tire itself. After that, solder the wire to the copper bus.

Connecting the film strips to each other is carried out according to the scheme of parallel connection.

Wires are output to connect to the thermostat.

It is important to remember that the wire has a load limit:

PV3-1,5 - maximum load 15 A (3,3 kW).
PV2-1,5 - maximum load 25 A (5.5 kW).

Using TM Heat Plus butyl tape, the joints, contact clips, solder points and unused ends of copper conductor bars are carefully insulated.

For insulation, butyl tape is cut into pieces, 3-5 cm wide.

Due to its special thermal properties and composition, butyl tape with the first heating by the heat of the emitted film becomes amorphous and slightly spreads over the surface, thus achieving an additional insulating and sealing effect.

On top of butyl tape for fixing and additional mechanical protection is glued Insulating heat-resistant tape Heat Plus.

Insulating tape Heath Plus not only serves as a reliable and qualitative fixative but also creates an additional insulating layer.

With proper and high-quality insulation with insulating and butyl tapes, the film becomes hermetically sealed. Thus, the heating system Heath Plus is not afraid of increased humidity or flooding of the floor.

The thermostat must be connected to the temperature sensor, the film and the network according to the manufacturer's instructions (included in the kit).

The thermosensor is fixed with an insulating tape on the underside of the infrared film

To avoid mechanical damage to the head of the temperature sensor, it is necessary to make a groove in the base of the floor and the substrate at a depth of 5 mm.

To fix the infrared film on the surface of the screed, a special heat-resistant acrylic adhesive is used.

Adhesive is applied to the film on a pre-marked surface with a spatula and evenly distributed using a comb of 3 mm.

The better the prepared surface of the floor at the initial stage, the less the consumption of glue. The average cost of installing the film is 0.7-1 kg per square meter.

Apply glue is recommended gradually, 40-60 cm in length at a time, then it is necessary to glue a part of the film.

Using a plastic spatula, it is necessary to expel a part of the air from under the film and evenly distribute the adhesive composition under the film.

For rooms with high humidity it is recommended to use waterproofing mastic instead of acrylic glue.

For better adhesion (adhesion) with tile adhesive, the surface of the film is covered with a special primer with Concrete-Contact.

The primer is applied to the film leaving the edges 10 cm along the perimeter of the film. It is necessary to smoothly coat the film with a primer and all edges to create a uniform layer and an additional protective surface that will have better adhesive properties.

Concrete-Contact is better to apply a wide brush brush with a width of 18-20 cm.

Soil consumption is approximately 0.3-0.5 kg per square meter.

After the surface has dried completely, you can start laying the finish coat.
