Use a Zehnder mounting frame on the floor
(available as an optional extra) for walls
with a mass of less than
160 kg/m

. This will reduce contact noise
as much as possible.
Install the mounting frame according to the
instructions in the corresponding manual.
Place the unit on the mounting frame.
■
Make sure the unit is locked in place.

The condensation formed in the unit must be drained
off frost-free, at a gradient and incorporate an air-seal
(siphon). To drain the condensation from the unit, two
bayonet connections are located on the bottom of the
unit. These connections are not airtight. Consequently,
it is necessary to close the unused connection with the
sealing cap supplied.
Always use a dry siphon and not a conventional
standard siphon, as the latter can dry out.
1. Connect the condensation drain seal cap to the
Zehnder bayonet connector on the supply/extract-air
side of the unit.
(Left-hand version = left side;
Right-hand version = right side).
2. Connect the condensation drain adapter to the
Zehnder bayonet connector on the outdoor/extract-
air side of the unit.
(Left-hand version = right side;
Right-hand version = left side).
3. Connect the dry siphon to the condensation drain
adapter. Take account here of the following matters:
■
The condensation drain adapter supplied is a
smooth tube with a diameter of 32 mm;
■
Zehnder recommends using a sealing sleeve
to create an airtight connection between the
condensation drain adapter and dry siphon. The
condensation drain is not suitable for gluing;
■
Ensure that the pipes fitted never rise above the
underneath of the unit;
■
Fit a dry siphon that is suitable for an
underpressure of at least 500 Pa to guarantee an
airtight seal. For a siphon with a ball as a dry lock,
this can be achieved by fitting a pipe or hose of at
least 90 mm between the dry lock and the Zehnder
bayonet connector;
■
Allow the connected dry siphon to drain freely into
the siphon of the domestic sewer.
Ensure that the water seal connected to the
domestic sewer is always full of water. This prevents
unpleasant odours.
