2.1 Site Requirements
The site for the unit must be dry and frost-free. The system
installation must be planned in detail, with particular attention
to the positioning of the fresh air and exhaust air ducts and to
include sufficient sound insulation.
NOTE: The temperature of the unit can be considerably lower
than the temperature of the room, it is being installed in. To
avoid undesirable accumulation of condensate, the circulation
of fresh and exhaust air must be provided in the room.
The unit is wall-mounted and should preferably be close to a
drain outlet for the condensation drain.
• The unit must be installed with due consideration of the
requirement for adequate and practical air ducting and
services (fresh air and exhaust air, electrical power). Ensure
enough space is provided on top of the unit and at its sides to
be able to mount the required air ducts, additional silencers
and bypass unit, see diagram 2.1.
• The installation site must be selected so that the ductwork
distances to and from the unit are as short as possible.
• The wall to which the unit is to be mounted must be of a
sufficient load-carrying capacity for the weight.
• It is possible that the supplied fixing are not suitable for the
installation wall, then it is the responsibility of the installer to
provide the fixings.
• The condensate drain must be connected with the supplied
condensate drain trap and to the water outlet with an odour
trap (siphon).
• If the unit is mounted on an internal wall, do not select
a location directly above bedrooms due to possible sound
transfer. Always choose a location above a non-occupied
room such as a hall or bathroom.
• With wood-joist ceilings or similar you can provide additional
sound insulation by adding insulation between the joists.
• Always ensure that the condensate drain is free running.
• To avoid annoyance by excessive noise select a sound-
absorbing hose for final connections from the unit to the air
outlets.
• Install a silencer. This will help to neutralise possible noise
transmission between the unit and the air ducting and reduce
annoyance by noise.
• Keep the air supply inlet at a sufficient distance from
discharge air, exhaust air and drain ventilation. Comply with
the legal building rules and regulations.
• When installing the fresh air input and discharge air ducts
you will have to ensure sufficient separation to avoid that the
discharged air being re-circulated into the fresh air input.
To avoid re-circulation, the minimum recommended distance
between supply and extract is 2 metres.
2.3 Remote Control
• The remote control must be mounted such that there is
enough space around it to complete the electric wiring as well
as easy operation of the control.
• The remote control must be installed inside the living space
and be easily accessible. For further details see section
“Installation - Controls”.
2.4 Atmosorb
• Electrical connection above mains voltage socket with
230 V 50 Hz mains voltage.
The connection must comply with the current rules and
regulations.

5.1 Function checks
Once all connections are correctly installed in accordance
with the wiring scheme, check the functions of the remote
control, the ventilation unit and the bypass. When doing so,
note that the unit must not be started until all ventilation ducts
are connected to the unit and the unit and all ductwork are
completely sealed.
In the user sections of the “Instructions for Use” manual you
will find in detail all the settings for the individual operating
modes and the special functions. For testing functions
proceed as follows:
• Select the “night” operating mode and check that the fans in
the domestic ventilation unit are operating at low output.
• Select the “day” operating mode and check that the fans in
the domestic ventilation unit are operating at medium output
(AIR2).
• Activate the special function”advance”. Check that the
fans in the domestic ventilation unit are operating at medium

5.8 Domestic Ventilation Unit Adjustment
Adjustment procedure
First of all ensure that the overall air flow calculated for the
installation is reached by the system. Then adjust the air
flow rates for the individual living spaces. Finally adjust the
individual air flow distribution within each living space.
Total Air Flow Adjustment
First adjust the desired air quantity calculated when the
system was designed with the remote control for all operating
modes (installer level). Proceed step by step as described in
table 5.1, page 19. In the table you will find the information for
the desired values.
NOTE: The planned air flow must be in the in the day mode
(2nd stage) because this is the standard operation mode.
Adjusting the air quantities at the system
1. Adjust all the exhaust and fresh air valves in the living
rooms to the middle opening of about 50 %. Then proceed in
accordance with the instructions given in the manufacturer
operating manual.
The air speed must not exceed 1.5 m/s at a distance of 50 cm
from the valve.
2. Make sure that all valves in the existing air duct manifolds
are completely opened.
3. Switch the domestic ventilation device into the operation
mode “day mode” using the remote control.
4. Measure the partial air flow at the strings with control
dampers if there are some available. Correct these settings if
required by adjusting the control dampers.
5. Open, if necessary, air inlet and air outlet valves if the
desired total air flow has not been reached.
6. Raise the ventilator revolution speed using the values in
table 5.1 if the total air flow is too low.
7. Go to the installer level in the remote control by pressing
the “mode” button for 10 seconds.
8. Press the “prog” buttons until “C-AIR” appears on the
display.
9. Correct the inlet air flow by pressing the - or + buttons until
the inlet and the outlet air volume are equal (see table 5.1).
5.9 Operator Delivery
