Danfoss Electric Floor Heating Cables Installation Guide

Introduction

In this installation manual, the phrase “heating cable” refers to heating cables in readymade lengths; heating cables on drums; heating cables on mesh; and preshaped taped heating cables. To get the full installation guide, warranty registration, product information, tips & tricks, addresses, etc. visit www.danfoss.com and www.gb.fhemanuals.danfoss.com.

Safety instructions

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

De-energize all power circuits before installation and service.
Residual current device (RCD) protection is required. RCD trip rating is max. 30 mA.
The screen from each heating cable must be earthed inaccordance with local electricity regulations
Heating cables must be connected via a switch providing all pole disconnection.
The heating cable must be equipped with a correctly sized fuse or circuit breaker according to local regulations.
Never exceed the maximum heat density (W/m or W/m²) for the actual application.
Strongly recommended to use the heating cable together with an appropriate thermostat to secure against overheating.
Caution! Do not use M1 classified cables in areas subject to high mechanical loads or impact, such like outdoor applications, on steel reinforcing grids, in concrete with sharp stones, roof and gutters, etc. The presence of a heating cable must
be made evident by affixing caution signs in the fuse box and in the distribution board or markings at the power connection fittings and/or frequently along the circuit line where clearly visible (tracing).
be stated in any electrical documentation following the installation.

Installation guidelines

It is not recommended to install heating cables at temperatures below -5°C.
Heating cable bending diameter must be at least 6 times the cable diameter. Do not bend connections.
Free end from cold lead must be protected by installer to avoid water from coming in.

Mechanical class

M1 — For use in applications with low risk of mechanical damage according to IEC 60800:2009, e.g. installed on even surfaces and embedded in screeds with no sharp objects.
M2 — Can be used in applications with high risk of mechanical damage according to IEC 60800:2009.
C — High mechanical strength according to IEC 60800:1992.
MMM — Marking for high mechanical protection class according to NF C 32-330:2002

Heating cables/mats can be customized for the specific project, depending on voltage, required output, length of heating cable and length of cold leads.
Note: It is the full responsibility of the installer/designer to use proper cold lead dimensioned for the purpose and assembly sets that establish sufficient mechanical strength, flammability resistance and water tightness – and to design the heating unit with correct output for the specific application to avoid overheating of the cable or building materials. 2) The heating cable shall only be installed in concrete or used while fully covered with non-flamable material e.g. soil or similar.
The cable are approved for use in contact with drinking water or water for human consumption – comply to Danish GDV (Godkendt til drikkevand) demands.
The cable are not approved for installation inside the water pipe and for use in contact with drinking water or water for human consumption, waste water, etc.!
