4 Instructions for the Installer

This chapter describes how you have to install the MTD-ERV 350.

4.1Preconditions for Installation

In order to be able to assess whether the ComfoAir 350canbeinstalledinaparticularroom,pleasepay attention to the following points:

•The MTD-ERV 350 must be installed in accord- ance with the local safety regulations and in- stallation instructions of i.a. the public utilities, and in accordance with the instructions in this manual.

•The installation location must be selected such that there is sufficient space around the MTD- ERV 350 for air connections and for carrying out maintenance work.

•The following installations must be present in the room:

-Air duct connections.

-230 V power supply with fused wall plug socket.

-Installations for condensation drainage.

•Roof openings must be air and vapour-tight. The outside air and exhaust air ducts must be insulated vapour-tight between the roof/gable opening and the MTD-ERV 350. This prevents the formation of condensation on the outside of the ducts.

•The exhaust air duct must have a double- walled or insulated roof opening.This prevents the formation of condensation between the layers of the roof.The exhaust air duct must be laid with a gradient towards the MTD-ERV 350.

•The MTD-ERV 350 must be installed in a frost- free room. The condensation must be dis- charged frost-free, with a downward gradient and using a siphon.The MTD-ERV 350 must be firmly connected to the siphon.

•The MTD-ERV 350 may only be connected to a non-powered extractor hood. Any other type of extractor hood system would interfere with the basic function of the balanced ventilation system.

•We recommend that silencers are installed on both the air intake and air discharge sides of the MTD-ERV 350. For further information, please contact your supplier.

In order to ensure a good and draught-free ventilation of the dwelling, gaps were deliber- ately left under the inside doors. If these gaps aresealed,forexamplewithdoorsealsorhigh- pile carpets, the ventilation in the apartment will stagnate. This would prevent the system from operating optimally.

4.2Installation of the MTD-ERV 350

4.2.1Transport and Unpacking

•Work carefully when transporting and unpack- ing the MTD-ERV 350.

Ensure that the packaging materials are disposed of in an environmentally favourable manner.

4.2.2 Checking the Scope of Supply

Should you discover any damage or missing parts of the supply product, please contact your supplier without delay. The scope of supply includes:

•MTD-ERV 350.

•Check the identification plate to see whether it is the correct type.

•4 x 45° connection elbows.

•Mounting brackets.

•Operating Manual.

The MTD-ERV 350 is available in the following types:
