Trouble Shooter

Existing Floor	Maximum load per m2
Wooden Floors	100 W/m2
Concrete Floors	150 W/m2

In all above situations, the floor temperature must be controlled with a DEVI floor sensor and

Devireg™ 550 thermostat/timer, or Devireg™ 130 thermostat.

INSTALLATION: KEY POINTS

•

Before laying the mat the floor sensor (in controller box) MUST be installed. The sensor is fitted into a tube (in mat box) which should be laid 20-30cm across the floor under the mat between a cable loop.

•Before laying check the continuity of the cable, it should match the Ohm rating on the Devimat™ label with a tolerance of -5 to +10% and check the insulation resistance which should read infinity.

•To install the mat simply cut and turn the mat. The heating cable must NOT be cut or subjected to strain around the area of the coupling, only the blue and black cables can be cut to suit.

•When installing more than one mat, all ‘cold tails’(blue/black wires) must be taken back to the connection point/controller, DO NOT wire one mat to another.

•After laying the adhesive the heating mat must be checked once again for continuity and insulation resistance, then connected by an authorised electrician.

•The blue central core is NEUTRAL and the black central core is LIVE. The outer surrounding copper wire is the earth screen and should be connected to earth.

•A flexible adhesive is required when installing the devimat™ product.

•Installation on new concrete floors should not be carried out for approximately 30 days to ensure thorough drying out.

Installing the Devimat™

1.Draw up a plan of the room and calculate the free floor area. Use the plan to work out how to lay the mat evenly across the floor and show the location of the cold tail (where the mat starts), floor sensor and connection box.

The Devimat™ should laid avoiding all floor obstructions and close floor fitting objects like pipes, baths and cupboards. It is acceptable to lay the devimat under suspended cupboards and wash basins.

2.Mark the positions of the floor fitting objects that will be installed once the floor is finished, so when laying the mat these can be avoided.

3.Each mat is supplied with a piece of 10mm flexible tubing (only one tube is required for each thermostat), this is for the floor sensor, so that in the unlikely event that the sensor fails, it can be

easily removed and

replaced without lifting the floor.

In some situations a small channel may have to be made in the floor to accommodate the tubing. If so, cut a channel from the thermostat position approximately 20-30cm across the floor.

It is important that the channel is positioned such that it lays between two heating wires and not across them and not above heating pipes below the floor. The

end of the tubing in the floor is sealed with tape to prevent

adhesive entering the tube.

4.The existing floor

should be prepared as normally required for tiling, this may include cleaning and

removing all loose particles, removing any sharp protrusions that may cause damage to the heating wire, priming the floor surface and bracing a timber floor with WBP

ply-for professional guidance refer to your adhesive manufacturers recommendations.

5. Before laying the mat should be tested-see page 7.

Remove the plastic outer and place the cold tail of the mat at the connection point. The Devimat™ has a self-adhesive backing, lay this to the floor and roll the mat out, if necessary the mat can be laid with the cable face down. In situations where the mat has to be turned over it can be secured using Devipins, hot glue gun (taking care not to damage the heating cable), staple gun or double sided tape.

6.When the Devimat™ reaches the end of the run, simply cut the grey mesh (NOT THE

RED CABLE) and turn the mat, positioning the next piece beside the first. When cutting

and turning the mat ensure there is a 50mm gap between the cable loops. To avoid risk of damage at later stage do not lay the mat where objects will be put onto or fixed to the floor.

7.If required, the cable can be removed from

the mesh and loops formed manually, but ensure the cables are spaced the same distance as those on the mat.

•The devimat™ must NOT be installed across two or more rooms

•The heating cables (RED CABLE) must not touch or cross each other.

•The heating cables (RED CABLE) must not be CUT.

•All the red heating cable must be within the floor.
