5.4 Installation of the air ducts
Air duct system
Zehnder ComfoFlat Zehnder ComfoTube

The unit can be installed with a special Zehnder air duct
system. Read the installation instructions for the air duct
system first. The next aspects must always be kept in
mind during the installation of the air ducts:
To prevent possible contact with the
running fans, the air ducts with a
minimum length of 900 mm must be
attached to the unit before connecting
the power supply.
■
Remove the protective cover just before mounting the
air ducts to the unit;
■
The distance (E) between the opening of the outdoor
air duct (A) and the opening of the exhaust duct (B)
must be sufficient to prevent a short circuit between
the airflows.
■
The position of the outdoor-air opening relative to
other possible sources of stale air is very important
(other air exhausts, street instead of garden, etc.);
■
Install the exhaust-air duct (D) to drain to the unit;
■
Insulate all ducts so they are vapour-proof (C). This
prevents leakages and the formation of condensation
on the outside of the duct;
■
Zehnder recommends that you fit thermal and
moisture resistant insulation to the supply duct from
the unit up to the supply valves. This will prevent
unnecessary temperature loss in the summer and
winter;
■
Install the air ducts with as little air resistance as
possible and free from air leakage;
Dimensions Minimum diameter of air ducts
350 160 mm
■
Ensure that the inside of the air ducts is entirely free
of obstruction. Air ducts must not have any sharp
bends, dents or long screws on the inside. Obstacles
will affect the performance and the maintenance of
the system;
■
Fit a silencer directly to the supply and extract air
connections;
■
Do not install a flexible air duct system. This will
disrupt the basic performance of the balanced
ventilation system. If a semi-flexible air duct system
is required, then only use a system approved by
Zehnder. Any other semi-bendable duct will disrupt
the performance of the balanced ventilation system;
■
Do not install a powered extractor hood to the
system.
