Multiflex 20 Heating Cable

Welcome
Thank you for choosing Ebeco. We hope that you will use and enjoy your underfloor heating system for many years to come. For the warranty to be valid, the product must be installed and handled as indicated in this manual. It is therefore important that you read the manual.

If you have any questions, please contact us at Ebeco.
Call +46 31-707 75 50 or send and
e-mail to [email protected].
Feel free to visit ebeco.com for more information.

Important
The underfloor heating system is a high voltage system and must thus be installed according to applicable regulations and of an authorised electrician. For the warranty to apply, the guarantee certificate must be correctly and completely filled in, and signed by an authorised electrician.

Heating cable for installation in concrete floors indoors or conservatories.
NOTE! Multiflex 20 must not be installed between timber joists. When packing on EPS concrete/cement, reinforcing mesh are required. When laying on the reinforcing mesh, the cable must be laid on the top of the mesh.

All loops are supplied with 1x 2,5 m cold cable. Voltage 230 V.

Before you start

Check that the supplied material corresponds with the delivery note.
Measure the cable’s insulation value, minimum 10 Ω.
Measure the cable’s resistance, see the values in the table below, the value can vary with positive/negative 10%. Enter the values in the Warranty Certificate.
When embedding in concrete the c/c (centre-to-centre) spacing is normally 20-25 cm and the cable is cast about 50 mm under the completed floor surface. In conservatories the c/c spacing is usually 12-15 cm. Using this reduced c/c measurement (<15 cm) the cable can also be laid in a layer of screed with a minimum depth of 15 mm, if the substrate is concrete. In order to obtain more exact c/c spacing divide the installation area by the length of the cable.
If fixing strips are used, secure this square to the cable’s installation (c/c = 100 cm).
You must not shorten the heating cable. Only the cold cable may be shortened. The cable is manufactured with an integrated return, i.e. only one end (cold cable) needs to be connected to 230V.
Plan the layout so that the cold cable splice and the end termination do not end up in the shower area.

Installation

Drumholder
To make it easier to lay the cable, a plastic drumholder is supplied in the pack. Place the drumholder in the perforated hole under the bottom of the pack. Lift the drum on to the drum holder and place a heavy object on the lid of the packWhen you pull on the cable, the drum rotates.

Embedding in concrete slab

Roll out the cable; start by the connection box. The cable is fixed to the fixing strip (E 89 350 35) or secured to the reinforcement bar using cables ties or the like. By the outer wall or windows it may be beneficial to lay the cable in half the c/c spacing (c/c = 100 mm) to minimize any draught. Do not place the cable in the wall or in the pipe (see picture). The cable’s cold cable joint must be cast into the concrete. Use concrete that flows easily, so that there is good contact between the cable and the con crete and so that no air pockets are formed. Never lay the cable directly over insulation or combustible material.
One cable section must not lie over another section or be crossed. Minimum spacing 60 mm.
The heating cable must not cross expansion joints in the concrete.
The cable should be insulation and resistance measured once again both before and after it has been embedded. This is to ensure that the cable has not been damaged during laying. The values has to be entered in the Warranty Certificate.
After laying and testing, the cold end of the cable must be positioned so that water cannot penetrate into the cable.
The room temperature is controlled with one of Ebeco´s EB-Therm thermostat. The sensor should be placed inside a conduit pipe, which is then laid in the screed or concrete between two runs, at least 0.5 m from the wall. Tape over the end of the conduit.
Secure the supplied sign by the distribution box also include a sketch of the cable installation.
The cable must not be used for at least 4 weeks after the completed jointing work, or according to the manufacturer’s instructions.

Laying on existing concrete substrate
Pull out the first loop of the cable and fix it with glue about 15 cm from the bend. Hold the cable in the glue until the glue has hardened. The distance between the cable and the wall should be approx. half the c/c-distance. Do the same with the next loop. The same principle applies for laying with fixing strip or on reinforcement.
