Safety instructions

Thin mats must always be installed according to local building regulations and wiring rules as well as the guidelines in this installation manual.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge, if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved, by a person responsible for their safety.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be made by children without supervision.
De-energize all power circuits before installation and service.
The screen from each heating element must be connected to earth in accordance with local electricity regulations.
Residual current device (RCD) protection is required. RCD trip rating is max. 30 mA.
Thin mats must be connected via a switch providing all pole disconnection that can be locked in the off position.
The thin mat must be secured with a correctly sized fuse or circuit breaker according to local regulations.
Thin mats must always be fully embedded with non-flammable material e.g. concrete, screed or tile glue by at least 5 mm incl. tiles.
Thin mats must always be controlled by a thermostat that limits the floor temperature to max. 35 °C (DEVIreg™ Smart, DEVIreg™ Touch, DEVIreg™ Opti or DEVIreg™ 530M).
Never exceed the maximum heat density (W/m) for the actual application.
In case of a wooden subfloor, the maximum installed output is 100 W/m².
On concrete subfloor the maximum of 200 W/m² is allowed if: the thickness of the concrete covering above the heating element, is more than 4 cm (40 mm).
Thin mats are not to be interconnected.
All thin mats in the same room must have the same heat density (W/m2) unless they are connected to separate floor sensors and thermostats.
The enclosed label must be filled in and placed adjacent to the distribution board, describing location of the thin mat.
If supply cord is damaged it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid hazard.

The presence of a thin mat must

be made evident by affixing caution signs in the fuse box and in the distribution board or markings at the power connection fittings.
be stated in any electrical documentation following the installation.

Installation guidelines

It is not recommended to install thin mats at temperatures below –5 °C.
The subfloor construction must be secure to avoid relative movement after installation.
Prepare the installation site properly by removing sharp objects, dirt, etc.
If walking on the elements is necessary during installation and carefully purring of screed, only use soft shoes.
Be careful not to damage the thin mat with sharp tools, shovel, bucket etc.
Minimum distance between heating cables; heating cable and conductive parts; heating cable and other heating sources such as hot water pipes and chimneys, must be at least 50 mm.
Heating cables may not touch or cross themselves or other heating cables.
Heating cable bending diameter must be at least 6 times cable diameter.
The thin mats are not to be installed on irregular surfaces.
The thin mat must be fully embedded in screed (fine concrete).
Do not lay thin mats under walls and fixed obstacles.
Do not place objects that will cause a thermal block e. g. furniture, thick carpets, etc. Min. 6 cm air space is required.
The flooring must not have a thermal insulation value of more than R < 0.18 m2K/W corresponding to 1.8 Tog.
Keep thin mats clear of insulation material, other heating sources and expansion joints.
Position the thin mat so that it is at least half the C- C distance from obstacles.
Thin mats must always be in good contact with the heat distributor (e.g. concrete).
Always roll out thin mats with the heating cables facing up.
Ensure not to crease the thin mat.
If additional securing is required hot melt glue, double adhesive tape or tile glue can be used.
When the thin mat reaches the area boundary, cut the liner/net and turn the mat before rolling it back. Do not cut the heating cable.
The thin mat and especially the connection must be protected from stress and strain.
Free end from cold lead must be protected by installer to avoid water from coming in.
