4 Instructions for the Installer
This chapter describes how you have to install the MTD-ERV 350.
4.1 Preconditions for Installation
In order to be able to assess whether the ComfoAir
350 can be installed in a particular room, please pay
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 suffi cient 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
fi rmly 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
are sealed, for example with door seals or high-
pile carpets, the ventilation in the apartment
will stagnate. This would prevent the system
from operating optimally.
4.2 Installation of the MTD-ERV 350
4.2.1 Transport 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 identifi cation plate to see whether it
is the correct type.
• 4 x 45° connection elbows.
• Mounting brackets.
• Operating Manual.
