PURPOSE
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility
and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream
of intake air.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with
high humidity.
Due to the ability to save heating energy by means of energy recovery, the unit is an important element of energy-efficient premises.
The unit is a component part and is not designed for stand-alone operation.
It is rated for continuous operation.
Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials,
coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust,
pathogenic germs).
THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED
PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT
THE APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED
PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED
ACCESS BY UNATTENDED CHILDREN.

THE EXTRACT AIR TEMPERATURE SHOULD BE NO HIGHER THAN +40 °C AND RELATIVE
HUMIDITY SHOULD NOT EXCEED 70 % OVER THE ENTIRE TEMPERATURE RANGE.
The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 70 %.
In order to prevent condensation on the internal walls of the units, it is necessary that the surface temperature of the casing is 2-3 °C higher
than the dew point temperature of the transported air.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:
• IP22 for the unit connected to the air ducts
• IP44 for the unit motors
The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

DESIGN AND OPERATING PRINCIPLE
Warm stale extract air from the room flows to the unit, where it is filtered by the extract filter, then air flows through the heat exchanger
and is exhausted outside by the extract fan.
Cold fresh air from outside flows into the unit, where it is cleaned by the supply filter. Then filtered air flows through the heat exchanger
and is moved to the room with the supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. The air flows are fully separated.
Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.
Depending on the model the unit is equipped with a supply air preheater or reheater with overheating protection.
The Micra 100 E Wi-Fi, Micra 100 E2 Wi-Fi units are equipped with a preheater.
The preheater is located upstream of the heat exchanger and is designed for its freeze protection.
The Micra 100 E1 Wi-Fi, Micra 100 E2 Wi-Fi units are equipped with a reheater.
The reheater is located downstream of the heat exchanger and is designed for extra heating of supply air to more comfortable temperature.

INSTALLATION AND SETUP
When the intake air temperature is below -3 °C, the preheater automatically warms up intake air so the average exhaust air temperature
downstream of the heat exchanger is not below +5 °C.
The reheater is switched on and off by means of a button on a sensor control panel, a remote control or via mobile application.
The heat exchanger freeze protection in Micra 100 Wi-Fi and Micra 100 E1 Wi-Fi unit models without a preheater is achieved by automatic
supply fan speed reduction according to extract air sensor readings.
The extract fan runs at maximum speed.
Temperature differences between supply and extract air flows in units with polystyrene heat exchangers lead to condensate formation.
Condensate is collected in the drain pan and is removed outside by the drain pipes through the exhaust air duct.
Condensate is not formed in units equipped with an enthalpy heat exchanger as moisture is transferred from one air flow to another
through a membrane.
The louvre shutters open automatically when the motors are switched on and close when the motors are switched off.
*An additional extract spigot can be fitted to the unit to connect the exhaust air duct from additional premises, e.g. a bathroom.
The spigot is included in the delivery set.

90 mm deep) to mount the unit. Install the expansion
anchors, remove the perforated fillers for the air ducts
from the mounting template and install the mounting
template back using a self-adhesive tape.
2.2. Cut air ducts of required length. Note that the
telescopic air duct end must protrude for the distance
that enables installation of the outer ventilation hood.
For details, refer to the installation instruction for the
ventilation hood.
The outer ventilation hood is available separately.
3. Fix the mounting template on the wall to install the
air ducts.
Insert the air ducts in the corresponding holes of the
mounting template.
Install the air duct with the minimum slope of 3 mm
for condensate removal.
To install the unit with an additional spigot, insert the
connecting bend into the prepared hole in the wall,
aligning the mounting template hole with a round
end of the connecting bend.
Connect a rectangular duct to the connecting bend.
4. Fill the spaces between the air ducts and the wall
with a mounting foam through the specially designed
holes in the mounting template.
Wait till the mounting foam hardens then take off the
mounting template and remove the foam excess.
Cut off the protruding air duct parts to be flush with
the wall surface.
