3. Points of attention:

Check before hand if the heating mat is the right size for the floor area to be heated and that there is sufficient electrical capacity (Amps.) available. Before installing the mat, the resistance reading should be taken and noted down on the inspection card in the center of this manual. (See point 7).

The connector cable can be extended or shortened, there must always be at least 0.5 meter of connecting wire left. The heating cable, attached to the glass fibre net, cannot be cut. The mats cannot be laid over each other and the heating cables may never cross each other! The cable junction (SPLICE) is the transition of the resistance cable (heating section of the mat) to the power cable (cold connection) is just within the heating mat and is marked.

A distance from the wall of 10 to 20 cm should generally be adhered to. The Heating mat may never be installed under fixed objects like wall units, kitchen units, baths, or showers and must be able to give off its warmth unimpeded. The Heating mat may only be incorporated into the free floor areas. As bathrooms consist mostly of a small free floor area the mat can only be installed as supplementary heating. Please contact your local supplier for information about use as main heating.

All installations must be wired through a suitably rated MCB or RCCD when applicable. All installations in wet areas must be wired through a dedicated  RCCD in line with the thermostat. All connections must be made by an approved electrician in accordance with current local regulations. The Heating mat is 3 to 4 mm thick and must be incorporated in a flexible adhesive or casting mortar suitable for floor heating. Check the manufacturers data.
The Heating mat has 1 connecting cable 3.5 meters in length (Twin Conductor) and has an end seal (loop) at the end of the mat. The end seal CANNOT be broken. The connector cable can be shortened, there must always be at least 0.5 meter of connecting wire left. The power supply must never be connected during installation. If multiple mats are installed in a space, they must be wired in parallel and a suitably rated junction box may be incorporated so that only one power cable runs to the thermostat. Maximum capacity of the thermostat is 16 Amperes. If combined area exceeds 23m², a Contactor will have to be fitted. The thermostat may only be installed by a qualified electrician. The sensorcable can be extended or shortened. The sensor must be installed in the middle of a cable loop for optimal temperature registration. Ensure that the sensor is installed well clear (min. 50 cm) of (hidden) radiator and water pipes, drains and electrical wiring. The sensor must always remain IN the sensor tube. Fit cap to end of the sensor tube. If the sensor ever needs to be replaced it can then easily be removed.
The Heating mat is primarily designed for installation on concrete floors. If laying on a wooden floor, all floors must be sheeted with a cement faced board which is compatible with heated floor systems. Or sheet the floor with 15mm WBP or Marine plywood, fix with screws at 200mm centres and then skim with 2-3mm of flexible tile adhesive and allow to dry, then proceed as installation for concrete base.

4. Necessary materials:

  • A SUNFLOOR Mat System.
  • Flexible tile adhesive or Self levelling compound and flexible grout suitable for floor heating.
  • Flexible cement and cement gun for expansion joints along the walls.
  • Approx. 2m flexible electrical conduit (16mm)
