Connection
The warm exhaust air is cooled by the outside air in
the heat exchanger. As a result, the moisture con-
tained in the room air condenses in the heat ex-
changer. The condensation forming in the heat ex-
changer is discharged via the condensation tray into
the condensation drain.
The connection for the condensation drain has an
outside diameter of 32 mm. This is located on the
underside of the MTD-ERV 350.
• Connect the condensation drain to the water
lock of the home drainage system using a pipe
or hose.
• Position the upper edge of the water lock at
least 40 mm below the condensation drain of
the MTD-ERV 350.
• Ensure that the end of the pipe or hose ends
under the water level.

least 60 mm below the water level. This
will prevent the MTD-ERV 350 from draw-
ing in air.
