Do not mount the side of the ComfoAir
against the wall due to the risk of impact
sound.
2.6.2 Mounting on the wall
Mount
the ComfoAir against a wall with a minimum
mass of 200 kg/m
2
.
1. Using a spirit level, fix the mounting bracket ho-
rizontally to the wall. Use M8 anchor bolts. Make
sure there is enough space under the ComfoAir
to mount the U bend.
2. Hang the unit on the mounting bracket.
3. Mount the condensation drain under the Com-
foAir. The stated dimension of 235 mm is an in-
dication only, and is dependent on the type of
condensation drain selected.
Make sure to leave a minimum space of 1 metre in
front of the ComfoAir for carrying out maintenance.
The ComfoAir does not require any space at the si-
des for effective operation.
Do not mount the side of the ComfoAir
against the wall due to the risk of impact
sound.
2.6.3 Connection of the air ducts
The following aspects must be taken into account,
while installing the air ducts:
■
Install the air exhaust duct so it drains in the di-
rection of the ComfoAir;
■
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;
■
To prevent unnecessary temperature loss in ei-
ther the summer or the winter, we recommend
fitting thermal and damp-proof insulation to the
supply ducts from the ComfoAir up to the supply
valves;
■
Install the air ducts with a minimum ø of 125
mm, as little air resistance as possible and free
from air leakage;
■
Install a silencer of at least 1m straight directly
onto the supply and return air connections. For
relevant advice, please contact Zehnder;
■
When using flexible channels only Zehnder
channel systems may be used. Any other flexible
channel will disturb the basic operating principle
of the balanced ventilation system;
■
We recommend that the ventilation system is
fitted with intake and exhaust valves made by
Zehnder.
