3.4 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 fi tted to allow suffi cient
room around the ComfoAir for the air connec-
tions and supply and exhaust ducts as well as
for carrying out maintenance activities.
• The room must offer the following provisions:
- Air duct connections.
- 230V electrical connection.
- Provisions for the condensation drain.
• The roof vents should be made airtight and
damp-proof. The outside air supply duct and
the air exhaust duct between the roof/wall pas-
sage and the ComfoAir must be rendered damp
proof. This prevents the formation of condensa-
tion on the outside of the ducts.
• To prevent unnecessary temperature loss in ei-
ther the summer or the winter, we recommend
fi tting thermal and damp-proof insulation to the
supply ducts from the ComfoAir up to the sup-
ply valves.
• The air exhaust duct must be fi tted with a dou-
ble-walled or insulated roof passage. This pre-
vents the formation of condensation between
the roof boarding. In addition, the air exhaust
duct must drain in the direction of the Com-
foAir.
• The 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.
• The cable used to connect the CC Ease panel
or the CC Luxe panel must have the following
specifi cations:
- Cable type: shielded twisted pair 4x0.34mm
2
.
- Cable length: 10 m maximum.
• We advise fi tting both the intake and the ex-
haust connections of the ComfoAir with silenc-
ers located directly against the unit. For more
information, please contact Zehnder.
A 10mm gap should be left under the in-
side doors in order to ensure effective and
draught-free air
fl ow in the house. If these
openings are obstructed, due to draught
excluders or deep-pile carpet, the air
fl ow in
the house will stagnate. As a result, system
performance will be compromised or fail al-
together.
3.5 Installation of the ComfoAir
3.5.1 Transport and unpacking
Take care when transporting and unpacking the
ComfoAir.
Make sure the packing material is disposed
of in an environmentally friendly manner.
3.5.2 Checking the delivery
Contact your supplier immediately in case of dam-
age or an incomplete delivery. The delivery must
include:
•
ComfoAir; Check the identifi cation plate to en-
sure that it is the required type.
• Mounting bracket;
• Manual.
The ComfoAir is supplied in the following types:
Type
ComfoAir L Luxe ComfoAir L Luxe PH
ComfoAir R Luxe ComfoAir R Luxe PH
Meaning of the suffi xes:
• L = Left.
• R = Right.
• PH = Pre-heater.
•
Luxe = Refers to the luxury version of the
connector print.
CC Ease panel or CC Luxe panel (optional) can be
ordered separately.
3.6 Wall mounting
Mount the ComfoAir against a wall with a minimum
mass of 200 kg/m 2 .
For other types of wall, we recommend using the
Zehnder mounting frame on the fl oor (available as
an optional extra). This reduces contact noise as
much as possible.
• Using a spirit level, fi x the mounting bracket
horizontally to the wall. Use M8 anchor bolts.
Make sure there is enough space under the
ComfoAir to mount the siphon.
• Mount the condensation drain (not supplied)
under the ComfoAir. The stated dimension of
235 mm is an indication 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 in view of the necessary
