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.
Operating conditions: +15oC - +24oC, relative air humidity <= 55%.
IT IS PROHIBITED to operate OXYGEN X-Air C200E ventilation device during cold period of a year in
premises with relative humidity level exceeding 55%. Excessive moisture condensation inside the Unit
can cause leakage or damage Units electronic components. Usage of the Unit in excess moisture
conditions will void the warranty!
The Unit should be installed horizontally with service cover looking downwards or upwards. L-shape
fastening brackets (provided) should be used to fasten Unit to the ceiling or flooring. Use ceiling pins
or locking sleeves (not included), depending on installation surface. It is recommended to use
vibroinsulation gaskets (not included) to ensure that Unit vibration will not be transferred to the
mounting surface.
7.2. 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
corresponding ducts of the Unit. The air intake opening in the outside wall should be protected
against precipitation ingress to ventilation duct by grille or roof.

13
Figure 2. Air intake duct connection diagram
IMPORTANT! At least 1° ventilation duct incline (refer to Figure 2) 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 difference
between outdoor and indoor air temperatures.
IMPORTANT! Avoid using duct grille with dense mesh – it can quickly become clogged with dust and
will prevent fresh air supply. The Unit is equipped with supply air filter to trap dust and insects.
7.3. Installing the maintenance and service hatch
When installing the Unit ensure enough space for its maintenance. Suspended ceiling in the room
should be installed at least 30 mm from the lowest point of the Unit housing.
Maintenance and service 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 3. Installation of maintenance and service hatch

14
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.
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 4. 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!
IT IS PROHIBITED to connect or disconnect control panel or WiFi controller without turning off the
mains power first. The failure of the control panel or the Unit due to improper 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.

IP protection class 20
8.2. Installation of the control panel
It is recommended to install control panel of the Unit in a living space (for example, in a corridor or
hall) at 1.5 – 1.6 m height from the floor for convenient access. Lay the control panel connection cable
supplied from the Unit location to the control panel location before finishing decoration works.
The maximum permissible installation distance of control panel from the Unit is 100 m. Use a flexible
mounting cable 4x0.22mm² to connect the panel, the resistance of each conductor must not exceed
40ꭥ.
Figure 5. Installation of the control panel
IT IS PROHIBITED to install control panel in a premises, where relative air humidity exceeds 70%.

16
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;
 Boost – ventilation boost activation by external switch;
 CO2 sensor – ventilation power increase based on readings of auxiliary CO2 or humidity
sensors connected;
 Away – reduction of ventilation power while away from home by security system or
external switch.
Function can be activated by short circuiting the respective digital contacts of RJ45 function
connector.
Figure 6. Contacts of functions connector
IMPORTANT! Only passive jumpers or electric relays should be used to activate the function!
IMPORTANT! If the Unit is being controlled by control panel with a knob, please make sure that
corresponding S2 switch does not block the usage of function (refer to section 9.1.6. Additional system
settings for more information).
IT IS PROHIBITED to connect the functions connector directly to electrical wiring network!
Optional RJ45 adapter can be used for more convenient connection:
