7. INSTALLATION OF THE UNIT
7.1. Selecting the mounting location
It is recommended to install the Unit in a heated room such as bath, storage room, boiler room or an
attic. Make sure, that there is sufficient space to install not only the Unit itself, but also auxiliary ventilation
system components – noise silencers or air distribution boxes. Make sure that there is a possibility to
connect the condensate drain pipe of the Unit to the internal or external sewerage system.
Operating conditions: +10oC - +30oC, relative air humidity <= 60%.
The Unit should be installed horizontally, with servicing cover looking downwards. 4 L-shape fastening
brackets (provided) should be used to fasten Unit to the ceiling. Use ceiling pins or locking sleeves (not
included), depending on installation surface. It is essential to use vibroinsulation gaskets (not included)
to ensure that Unit vibration will not be transferred to the mounting surface.
7.2. Installation incline
IMPORTANT! After Unit installation, make sure that the condensate drain corner is positioned lower than
remaining Unit corners (refer to Figure 2). This will ensure smooth removal of accumulated condensate.
Corresponding distances must be maintained from ceiling plane, when installing the Unit:
No. Distance from horizontal plane
1 20 mm
2 10 mm
3 0 mm
4 10 mm

13
Figure 2. Horizontal installation diagram
7.3. Connecting ducts
It is recommended to install outside air supply and exhaust ducts as far as possible from each other to
prevent the ingress of contaminated air back to premises. Please refer to local construction regulations.
Make sure that outdoor humidity or precipitation will not get into the Unit, when connecting outside air
supply and exhaust ducts. Make sure that openings in the outside wall are installed lower than the Unit
itself. The air intake opening in the outside wall should be protected against precipitation ingress to
ventilation duct by grille or roof, with mesh to prevent ingress of insects and other small objects.
Figure 3. Air intake duct connection diagram
IMPORTANT! At least 1° ventilation duct incline should be ensured to prevent ingress of outdoor
humidity or precipitation into the Unit.

IMPORTANT! Both outside air intake and exhaust ducts should be covered with a layer of thermal
insulation of sufficient thickness to prevent condensation of humidity on their walls due to different
outdoor and indoor air temperatures.
7.4. Installing the maintenance and servicing hatch
When installing the Unit ensure enough space for its maintenance. Suspended ceiling in the room should
be installed at least 40 mm from the lowest point of the Unit housing (refer to section 8.2. Installation
incline).
Maintenance and servicing hatch installed in the ceiling should be of suitable size to allow convenient
access to all Unit components. At least 100 mm distance should be ensured from every edge of the Unit.
Figure 4. Installation of maintenance and servicing hatch
IMPORTANT! Owner of the Unit shall ensure the possibility to perform Unit maintenance. If there is not
enough space for Unit maintenance, the manufacturer’s representative is entitled to refuse to perform
maintenance or repairs.

15
7.5. Connecting the condensate drain
The Unit condensate drain should be connected to indoor or outdoor wastewater network. If condensate
drain is installed in non-heated premises or directed outdoors, it must be thermally insulated or equipped
with electric heater.
Install a round rubber gasket into the condensate drain socket, then firmly screw the condensate drain
nozzle in by hand.
Figure 5. Installing the condensate drain
IMPORTANT! Do not use pliers or other similar tools, as excess power applied may damage the unit.
The necessary incline of the condensate drain should be ensured during the installation: at least 2° incline
should be ensured in the horizontal part of the system.
Siphon is the obligatory part of the condensate drain system. It is recommended to use HL138 or similar
type, internally or externally mounted siphon with mechanical odor control damper. Siphon should be
installed according to the diagram “Connecting the condensate drain″, ensuring that the manufacturer
instructions on the incline, distances, necessary inspection hatch for the selected siphon model are
observed.
Figure 6. Connecting the condensate drain

8. CONNECTION OF THE UNIT
Mains supply, control panel cable and, if necessary, comfort function connector should be connected to
the Unit, according to the following diagram:
Figure 7. Unit connection
IT IS PROHIBITED to connect any cables or devices to the connectors of the control panel and comfort
functions, despite similarity to any standard connectors. External similarity of connectors does not
guarantee compatibility – the connected devices may fail or damage the Unit. The failure of the Unit due
to incompatible supplementary parts connection will void the warranty!
8.1. Connecting electric circuit
WARNING!!!
 To prevent accidents and potential damage to the Unit, it can only be connected by a qualified
technician. Do not attempt to do that by yourself!
 Mains supply power rating shall comply with the rating indicated in the Unit manual.
 Mains supply should be disconnected when connecting the Unit.
 The Unit should be connected according to diagram provided in the User Manual.
 Only power cable provided with the Unit should be used to connect it to power source.
 Grounding should be installed in compliance with the requirements of effective legislation and
standards when connecting the Unit to mains supply.
 Electric circuit must be equipped with suitable power circuit-breaker.

8.2. Connecting the control panel
It is recommended to install the control panel in residential premises (e.g., corridor or lounge) for
convenient access. It is recommended to install the control panel at 1.5 – 1.6 m height from the floor.
Figure 8. Control panel installation
IT IS PROHIBITED to install control panel in a premises, where relative air humidity exceeds 90%.

8.3. Connector of comfort functions
The Oxygen X-Air C200 device supports the following external functionality:
 Fire alarm – emergency shutdown of the Unit upon activation of fire alarm;
 WC boost – ventilation boost activation upon switching on the light in the bathroom;
 CO2 sensor – ventilation power increase based on readings of auxiliary CO2 or humidity
sensors connected;
 Away – reduction of ventilation power when no one is at home. Requires security system to
be installed in the premises.
Functions can be activated by short circuiting the respective digital contacts of RJ45 function connector.
