Mounting On The Wall; Connecting The Condensation Drain - Zehnder ComfoFond-L Q Serie Manual Del Instalador

4.2 Mounting on the wall

Mount the ComfoFond-L Q against a wall with a
minimum mass of 200 kg/m
frame (available as an optional extra) must be used
for other walls. (see appendix: Mounting pictures).
This reduces contact noise as much as possible.
Make sure to leave a minimum space of 110 cm
in front of the ComfoFond-L Q to perform any
necessary maintenance work.

(see appendix: mounting pictures).
2. Place the ComfoFond-L Q in the wall mounting
bracket.
3. Rotate outdoor connecter bend (A) of the
ventilation unit and connect it to the supply air of

ComfoFond-L Q, as described in the chapter on
mounting the condensation drain.
5. Fit the fluid circuit (subsoil heat collector),
including the boiler safety group, to the exhaust
side (C) of the ComfoFond-L Q, as described in
the chapter on mounting the fluid circuit.

ComfoFond-L Q to the ventilation unit, as
described in the chapter on mounting the
electrical connections.

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 Q.
The condensation drains of the ComfoFond-L
Q and the ventilation unit must have a seperate
siphon. Do not connected them directly to the
same Siphon.
