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 instal-
lation regulations of power and water compa-
nies, as well as the instructions in this manual.
• The system must be tted to allow sufcient
room around the ComfoAir for the air connec-
tions 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.
We do not recommend installing the Com-
foAir in areas with a higher average humidity
(such as bathroom or toilet). This will prevent
condensation on the outside of 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).
• Thecableusedto connecttheCCEase panel
or the CC Luxe panel must have the following
specications:
- Cable type: shielded twisted pair 4x0.34mm2.
- Cable lengtth: 10m maximum.
The connections of the CC Ease panel must
be crossed. (Rx must be connected to Tx).
• Agapshouldbeleftnearthedoorsinorderto
ensureeffectiveand draughtfreeairow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
airow in the house will stagnate. As a result,
system performance will be compromised or
fail altogether.
2.5 Installation of the ComfoAir
2.5.1 Transport and unpacking
Take the necessary precautions when transporting
and unpacking the ComfoAir.
Make sure the packing material is disposed
of in an environmentally friendly manner.
2.5.2 Checking the delivery
Contact your supplier immediately in case of dam-
age or an incomplete delivery. The delivery must
include:
• ComfoAir;
Checktheidenticationplatetoensurethatit
is the required type.
• Mountingbracket;
• Documentation.
The ComfoAir is supplied in the following types:
Type
ComfoAir 550 L Luxe
ComfoAir 550 R Luxe
ComfoAir 550 L Luxe ERV
ComfoAir 550 R Luxe ERV
ComfoAir 550 L Luxe VV
ComfoAir 550 R Luxe VV
Meaningofthesufxes:
* L = Left version
* R = Right version
* VV = Contains a preheater element by default.
* ERV = Contains a enthalpy exchanger by default.
* Luxe = Contains a connection board with extra func-
tion by default.
CC Ease panel or CC Luxe panel (optional) can be ordered
separately.
2.6 Mounting of the ComfoAir
2.6.1 Mounting on the wall
Mount the ComfoAir against a wall with a minimum
mass of 200 kg/m2.Forothertypesofwall,werec-
ommend using the Zehnder mounting frame on the
oor(available asanoptionalextra).This reduces
contact noise as much as possible. The ComfoAir
does not require any space at the sides for effective
operation.
Do not mount the side of the ComfoAir
against the wall due to the risk of impact
sound.
1. Fastenthemountingbrackettothewall.Make
sureitislevelandatleast878mmfromtheoor
(depending on the type of condensation drain
selected).
Leave a minimum space of 1m in front of the
ComfoAir for carrying out maintenance.
2. Hang the ComfoAir 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.

EN - 8
2.6.2 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
direction 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
tting 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 180
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airconnections.For
relevant advice, please contact Zehnder.
• When using exible channels only Zehnder
channelsystemsmaybeused.Anyotherex-
ible channel will disturb the basic operating
principle of the balanced ventilation system.
• We recommend that the ventilation system is
ttedwith intake andexhaust valvesmade by
Zehnder.
• We recommend that the ventilation system is
ttedwithanon-poweredextractorhoodmade
by Zehnder.

2.6.3 Connection of the condensation drain
ComfoAir - Right ComfoAir - Left
Standard heat exchanger
Warm exhaust air is cooled by the outside air in the
heat exchanger. This causes the moisture in the in-
door air to condense in the heat exchanger. The
condensation water created in the heat exchanger
is fed to a PVC condensation drain.
The connection for the condensation drain has an
external diameter of 32 mm. It is located under-
neath the ComfoAir.
• Connect the condensation drain, via a pipe or
hose, to the water seal (siphon) of the domes-
tic waste-water system.
• Position the upper edge of the water seal at
least 40 mm underneath the condensation
drain of the ComfoAir.
• Make sure that the outer end of the pipe or
tube exits is at least 60mm below the water
level.
Ensure that the water seal connected to the
domestic waste-water system is always full
of water. This prevents the ComfoAir from
sucking in any leakage air.
Enthalpy exchanger
Whenthe ComfoAiristted withanenthalpyex-
changer the humidity from the extracted air is part-
ly transferred to the fresh supply air. In this case
you delay the process of drying out the house in
dry winter months, additionally there is no con-
densate that must be drained from the ComfoAir.

9 - EN
Therefore a condensation drain is not necessary
with an enthalpy exchanger.
Ensure that the condensation drain is sealed.
This prevents the ComfoAir from sucking in
any leakage air.
The condensation drain can be sealed with a stan-
dard screw-cap.
2.7 Commissioning the ComfoAir
After installation, the ComfoAir must be commis-
sioned.
This can be done via the P menus on the digital op-
erating device. These P menus can be used to enter
various settings (ventilation programmes, in partic-
ular) for the ComfoAir. An overview of the available
P menus is given below:
Menu Options
P1 Reading statuses (from menu P2)
P2 Setting time delays
P3 Setting and reading the ventilation levels
P4 Setting and reading the temperatures
P5 Setting additional programmes

P9 Reading statuses (from menu P5 and P6)
P menus P1, P2 and P9 can be accessed by the
user, mainly to read statuses and set time delays.
The remaining P menus P3 to P8 are intended sole-
ly for the installer.
The ComfoAir's bypass valve will not work
for the rst 4 minutes after a power cut un-
less the programme mode is activated.
2.7.1 CC Ease panel
The ComfoAir Luxe can be operated and commis-
sioned by means of a CC Ease panel, which can
be ordered separately. The CC (Comfort Control)
Ease panel is a digital operating device which can
be mounted on the wall in the living room and from
there communicates with the ComfoAir.
