4.2 Mounting on the wall
Mount the ComfoFond-L Eco against a wall with a
minimum mass of 200 kg/m
2
. The Zehnder support
frame (available as an optional extra) must be used
for other walls. This reduces contact noise as much
as possible.
Make sure to leave a minimum space of 110 cm in
front of the ComfoFond-L Eco in view of the
necessary maintenance work.
Where necessary, reposition the ComfoAir Luxe
documentation to make sure it is still accessible
following the installation of the ComfoFond-L
Eco.

4.3 Connecting the condensation drain
Take account of the following factors (see also
Appendix: Condensation drain pictures)
when fitting the condensation drain:
The condensation must be drained off frost-free,
at a gradient, using an appropriate siphon;
Connect the condensation drain (air-tight) via a
pipe or a hose with a siphon (with a water seal of
at least 60mm) to the sanitary pipework;
Position the upper edge of the siphon at least 60
mm underneath the condensation drain of the
ComfoFond-L Eco.
The condensation drains of the ComfoFond-L
Eco and the ventilation unit must always be
connected with a siphon.
