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 
installation regulations of power and water 
companies, as well as the instructions in this 
manual.

  The system must be fitted to allow sufficient 

room around the ComfoAir for the air 
connections and supply and exhaust ducts as 
well as for carrying out maintenance activities.

  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.

 

We do not recommend installing the 
ComfoAir 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).

  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.

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 

damage or an incomplete delivery. The delivery 

must include:

   ComfoAir;

  Check the identification plate to ensure that it is 

the required type.

  4 x 45O connection bends;

  Mounting bracket;

 Documentation.

The ComfoAir is supplied in the following types:

Type

ComfoAir 350 Basic L

ComfoAir 350 Basic R

ComfoAir 350 Basic L RF

ComfoAir 350 Basic R RF

ComfoAir 350 Basic L VV

ComfoAir 350 Basic R VV

ComfoAir 350 Basic L VV RF

ComfoAir 350 Basic R VV RF

Meaning of the suffixes:

*   L  

=  Left version

*   R  

=  Right version

*   RF 

=  Contains the wireless control function by 

   

 default.

*   VV   = Contains a preheater element by default

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 
recommend using the Zehnder mounting frame 
on the floor (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 floor 
(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 

ComfoAir. The stated dimension of 235 mm is an 
indication only, and is dependent on the type of 
condensation drain selected.
