maintenance work.
The ComfoAir does not require any space at the
sides for effective operation.
Do not mount the side of the ComfoAir against
the wall due to the risk of impact sound.
3.6.1 Connection of the air ducts
Install a straight silencer directly onto the supply
and return connections. For more advice, please
contact Zehnder.
Subsequently, the air ducts to be connected, with a
minimum ø of 180 mm, must be installed with as lit-
tle air resistance as possible and must be free from
air leakage.
• Do not use fl exible ducting and leave room for
mounting silencers.
• Insulate the outside air supply and the air ex-
haust duct between the roof/wall passage to
render the ComfoAir damp proof. This prevents
the formation of condensation on the outside
of the ducts.
• Install the air exhaust duct so it drains in the
direction of the ComfoAir.

3.6.2 Connection of the condensation drain
Warm exhaust air is cooled by the outside air in the
heat exchanger. This causes the moisture in the
indoor air to condense in the heat exchanger. The
condensation water created in the heat exchanger
is fed to a PVC condensation drain.
ComfoAir - Right ComfoAir - Left
The connection for the condensation drain has an
external diameter of 32 mm. It is located underneath
the ComfoAir.
•
Connect the condensation drain, via a pipe or
hose, to the water seal of the domestic waste-
water system.
• Position the upper edge of the water seal at
least 40 mm underneath the condensation drain
of the ComfoAir.
• Make sure that the outer end of the pipe or tube
exits below the water level.
Ensure that the water seal connected to the
domestic waste-water system is always full
of water.
Also ensure that the end of the hose is at
least 60 mm under the level of the water. This
prevents the ComfoAir from sucking in any
leakage air.
