Installation

The general guidelines and assumptions are the same as for the technical information for underfloor heating systems. Floor ducting to supply individual rooms with supply air is laid underneath the underfloor heating pipe and is therefore integrated into the underfloor heating. In addition the 30/50 mm high ducts are recessed into the insulation so that their upper surface is at the same height as the AIRCONOMY^® system module and the AIRCONOMY^® folding panel. The heating pipes are fixed with plastic clips on the folding panel or between the pipe-locating profiles of the AIRCONOMY® system module. It is normally not necessary to aspects the floor duct. The arrangement of the heating circuit should be done so that the duct is crossed by the heating pipe. If this is not possible then a clip rail should be glued to the ducting to accept the heating pipes. It is a prerequisite that the building works of plastering and pipe installation for building services have been completed. In winter it is imperative to guarantee no freezing. The plastering walls must be completed right up to the floor slab and the floor slab should be kept free of electrical cables and conduits. If this is not the case then a leveling layer should be put down to create a flat surface to accommodate the heat and noise dampening. This is also necessary when the floor slab shows unacceptable undulations. Before the start of laying, the concrete foundation should the comprehensively swept. Any areas next to earth should be sealed against rising damp. This can be achieved by laying the damp barrier PE 3/300.

INSTALLATION

• Position manifold Cabinet and install primary connections
  
• Connect heating circuit manifold
  
• Lay edge insulation strips, system panels and heating pipes
  
• Wire up controls
  

It is important that the manifold cabinets, heating circuit manifolds and system controls be designed for optimal integration.

Manifold Cabinet

• Surface-mount and flash-mount cabinets in 3 sizes
  
• Low build height from 90 mm
  

Heating circuit manifold

• Model Komfort 90 – 3 (with flowmeter)
  
• Sizes from 2 – 14 circuits
  
• For accessories and installation see underfloor heating systems technical information 1.6
  

Varimatic Controls

• 230 V wired or RF control
  
• Modular expansion
  
• For technical details of the components please see underfloor heating systems technical information 1.7
