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.

Diagram 2.1
2.2 Installation Minimum Clearances
• Please refer to diagram 2.1.
• For the installation, at least 100mm of free space on the
side of the device must be provided.
• For installation, filter replacement and maintenance works,
1 m working space in front of the ventilation unit is needed.
Over and beneath the device at least 30 cm are required.
