PURPOSE
The unit can be equipped with an adapted automation kit, which includes: a control panel, a control unit, an optotriac to control heater,
a duct temperature sensor, and a differential pressure sensor.
The use of an automation kit allows controlling air flow, temperature (heating), and air filtration, which can significantly save energy.
The unit is intended for filtering, supplying and heating purified intake air in private homes, offices, hotels, cafés, conference halls
and other residential and public spaces.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens and other spaces with
high humidity.
The unit is a component part and is not designed for stand-alone operation.
The unit 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.

TECHNICAL DATA
The unit is designed for application with the ambient temperature ranging from +1 °C to +40 °C and relative humidity up to 80 %.
In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above
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
6
The unit allows controlling the air flow, air temperature (preheating) and air filtering.
• Air flow can be adjusted by controlling the fan speed.
• Air heating is provided by an integrated electric heater (item 2).
• The unit is equipped with an air filter with filtering class G4 (item З).
• Hinged (item 4) or removable cover optimally uses the space for installation.
• Unit design allows standard connection to rectangular air ducts of the duct work.
• The unit is equipped with two sensors-thermal switches: one is a safety thermal switch with automatic restart, and the second
one is an emergency thermal switch with manual restart when the RESET button is pressed (item 5).
• The BLAUBOX ME...PRO units are additionally equipped with an automation unit (item 6).

MOUNTING AND SETUP
READ THE USER’S MANUAL PRIOR TO MOUNTING THE UNIT.
The unit should be mounted so that the arrow on the cover coincides with air flow direction in the system in order to provide access for
maintenance, servicing or replacement work.
Enough space must be provided for the cover to open all the way.
The unit can be mounted on flat surface or suspended on a threaded rod ensuring a secure fixation to prevent unit detachment or falling
down (in consideration of the unit weight and the mating surface material) using all the available L-shaped support brackets with an
antivibration damper attached to the unit base.
The unit is designed for mounting into rectangular air ducts.
• The duct should be connected via a flexible connection to eliminate transfer of noise and random vibrations.
• The dimensions of the connected air duct must be the same as the dimensions of the hole in the unit.
The recommended distance between the unit and other elements of the system must be not less than the diagonal of the unit spigot
(the distance from corner to corner of its air duct part).

The required number of wires, their cross-section (mm²), as well as the ratings of the circuit breakers are shown in the table.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
• The unit is rated for connection to 1~220-240 V/50 (60) Hz or 3~400 V/50 Hz power mains according to the wiring diagram.
• The connection must be made using durable, insulated and heat-resistant conductors (cables, wires). The conductor cross-
section selection shall be based on maximum permissible current and maximum permissible wire heating, which depends on
its type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the
circuit in the event of overload or short-circuit. The position of the external automatic circuit breaker must ensure free access
for quick power-off of the unit. The automatic circuit breaker nominal current must exceed the ventilator current consumption,
see the Technical data section or the unit label. It is recommended to select the nominal current of the circuit breaker from the
standard series, following the maximum current of the connected unit. The circuit breaker is not included in the delivery set and
can be ordered separately.
