1 Product specifications is a hot-water floor heating mat with low construction height (approximately 10 mm), which makes it especially suitable for renovation jobs in existing buildings. The capacity of your installation is strongly dependent on the capacity of the circulation pump. Please consult your plumber to determine the capacity of your heating system. Each room with floor heating should be equipped with its own thermostatic room temperature control, such as a Danfoss RTL valve with TH function (not included).

2 Installation instructions Congratulations on the purchase of your new Danfoss product Please observe the following installation guidelines in order to obtain good results and longterm trouble-free operation. UK 2.1 Initial planning Please take the manufacturer s data into consideration with regard to subsequent covering of the heating mat with floor levelling compound, screed or the like. The selected materials must be suitable for use on top of a floor heating system and should have a certain degree of elasticity Installation is considerably simplified if the fitting location for control is specified in the planning stage. The control and accessories, such as the manifold, should remain easily accessible after installation. Plan: Follow the Danfoss installation instructions step by step. This will avoid any problems during mat installation and adjustment. Sketch the floor plan of your room on the mat sheet (Figure 1) Draw your mat (width 48 mm) on the floor plan with a separation of 2 cm between the runs. The woven glass net can be cut as necessary to change directions (Figure 2). Figure 1 Figure 2 Transfer the markings from your drawing to the floor so you can see exactly where you should start and stop 2.2 Preparation and cleaning Before installing the heating mat, you must prepare the floor surface (Figure 3). The substrate must be level, structurally sound, and free from dust, grease and oil. Danfoss 2015.09 VIEGG102 5
You should preferably start laying the heating mat close to the connection point. All connections should remain readily accessible afterwards. Always connect the RTL valve (not included) to the end of the hose (supply line), not to the start. Figure 3 It may be necessary to apply a bonding agent (primer), depending on the substrate. This ensures proper bonding of the heating mat. If you use an RTL control with TH function to adjust the room temperature, install the RTL valve (not included) ahead of the heating mat (see the installation instructions for Danfoss controls). 2.3 Laying the mat Remove the protective film from the mat and roll it out according to your floor plan, with the selfadhesive side facing down (Figure 4). Figure 5a Figure 4 When you encounter an obstacle (wall, cabinet, toilet, end of the room, etc.), cut the woven glass net (but not the pipe) and continue laying in another direction (Figures 5a & 5b). The length of the pipe attached to woven mat has been selected to match the required connection length. The pipe length is calculated to ensure that in the worst case, you can always return the pipe along the same path as you used when rolling out the mat. You can use the pipe couplings and angle connectors available as accessories to replace a damaged pipe section or extend a pipe that is too short, if necessary. 6 Danfoss 2015.09 VIEGG102
Before lengthening the pipe, you should obtain the approval of your plumber. Note that when more than one mat is installed, all mats must be the same size. Examples: 5 m² = 2 x 2.5 m², corresponding to 2 x 3 m² (mats must be shortened) UK 6 m² = 2 x 3 m², corresponding to 2 x 3 m² (packing unit) 7 m² = 3 x 2.33 m², corresponding to 3 x 3 m² (mats must be shortened) Figure 5b If you intend to install several Danfoss ECmat Aqua mats in the same room, you must select the right distributor in advance. Distributors are available for installation of a single mat as well as for installation of two or three mats. At this point you should have arrived at the manifold with the ends of the connecting lines. Cut the pipes to length with straight, unchamfered and burr-free edges. This is necessary to ensure secure fitting of the connector components. Note: Push the ends of the connecting lines into the manifold until they reach the stop. Attached pipes can be disconnected by slightly lifting the locking ring. This intelligent technology eliminates the need for tools. 2.4 Intermediate test After completing all the installation steps, you should recheck the entire procedure. The piping of the mat should now become warm. Check that all parts have been installed or connected properly. Are all connectors firmly secured? Start up your heating system again with the RTL valve (not included) closed. After slowly filling the system with water, check all connections and joints for leaks (visually or by touch). Correct any installation errors by following the above procedure, and then repeat the leak test. If everything is okay, close the RTL valve (not included) for the Danfoss ECMat Aqua. (See also the installation instructions for Danfoss controls.) This intermediate test must be performed before the mat is covered with floor levelling compound or screed. Danfoss 2015.09 VIEGG102 7
2.5 Covering & final test After the mats have been laid as desired, press them firmly against the floor again to ensure good adhesion. the manufacturer s data for the materials that are used (Figures 6 & 7). Figure 6 Then cover the mats with an elastic levelling compound, levelling filler or the like. Observe Figure 7 The floor heating should be switched off during the curing phase. 8 Danfoss 2015.09 VIEGG102
