1 Introduction
The device's name is ComfoAir 160. In the following it
will be referred to as ComfoAir.
The ComfoAir is a balanced ventilation system with
heat recovery in order to create healthy, balanced and
energy-efficient ventilation in houses. The ComfoAir
has a CE marking on the identification plate. The iden-
tification plate can be found on top of the ComfoAir.
1.1 Warranty and liability
1.1.1 Guarantee conditions
The ComfoAir is covered by a manufacturer’s war-
ranty for a period of 24 months after fitting up to a
maximum of 30 months after the date of manufacture.
Warranty claims may only be submitted for material
faults and/or construction faults arising during the
warranty period. In the case of a warranty claim, the
ComfoAir must not be dismantled without written per-

1.1.2 Liability
The ComfoAir has been designed and manufactured
for use in balanced ventilation systems incorporating
Zehnder heat recovery systems. Any other application
is seen as inappropriate use and can result in dam-
age to the ComfoAir or personal injury, for which the
manufacturer cannot be held liable.
The manufacturer is not liable for any damage origi-
nating from:
• Non-compliance with the safety, operating and

2.3 Dimension sketch 2.4 Installation conditions
In order to determine whether the ComfoAir can be
installed in a certain area, the following aspects must
be taken into account:
• The ComfoAir must be installed according to the
general and locally applicable safety and installa-
tion regulations of power and water companies, as
well as the instructions in this manual.
• The system must be tted to allow sufcient room
around the ComfoAir for the air connections and
supply and exhaust ducts as well as for carrying
out maintenance activities.
•
T he ComfoAir must be installed in a frost-free space.
The condensation must be drained off frost-free, at a
gradient and incorporate a 'U' bend.
Condensation may form on the outside of
the ComfoAir if the unit is fitted in a space
with higher average humidity levels (such as
a bathroom, shower, toilet or kitchen). This is
not a problem for the ComfoAir.
• The room must offer the following provisions:
- Air duct connections.
- 230V electrical connection.
- Provisions for the condensation drain.
- Wiring for an wired 3-position switch
(optional).
• A gap should be left near the doors in order to
ensure effective and draughtfree airflow in the
house. A gap under the inside doors must be
atleast 10mm.
If these openings are obstructed, due to
draught excluders or deep-pile carpet, the
airflow in the house will stagnate. As a result,
system performance will be compromised or
fail altogether.
