Installation Guide for Danfoss Thin Mats

Quick Guide

Danfoss Thin Mats are floor heating elements consisting of heating cables mounted on a self-adhesive mesh. This guide covers the installation and safety requirements for the ECheat, ECcomfort, and ECmat series.

Safety Instructions

Installation must comply with local building regulations and wiring rules. Key safety requirements include:

• RCD Protection: A Residual Current Device (RCD) with a maximum trip rating of 30 mA is required.
• Thermostat Control: Mats must be controlled by a thermostat that limits the floor temperature to a maximum of 35 °C (e.g., ECtemp Smart, ECtemp Touch, or ECtemp 530M).
• Embedding: Mats must be fully embedded in non-flammable material (concrete, screed, or tile glue) at least 5 mm deep, including tiles.
• Electrical Connection: Must be connected via an all-pole disconnection switch that can be locked in the off position.
• Warning: The presence of a thin mat must be indicated by warning signs in the fuse box and distribution board, and noted in electrical documentation.

Installation Guidelines

Follow these steps and precautions for a successful installation:

• Temperature: Do not install at temperatures below -5 °C.
• Preparation: Clean the installation site thoroughly, removing sharp objects and dirt.
• Spacing: Maintain a minimum distance of 50 mm between heating cables, conductive parts, and other heat sources (e.g., hot water pipes, chimneys).
• Handling: Do not crease the mat. Use soft shoes if walking on the elements during installation.
• Cutting: Do not cut the heating cable. If the mat reaches a boundary, cut the mesh/liner and turn the mat before rolling it back.
• Obstacles: Do not install under walls or fixed obstacles. Ensure at least 6 cm of air space around furniture or other objects that could cause a thermal block.
• Protection: Protect the connection and the free end of the cold lead from stress, strain, and water ingress.
