Due to the ability to save heating energy by means of energy recovery the unit is an important element of energy-ecient premises.
Theunit is a component part and is not designed for independent operation.
The unit is designed to provide permanent controlled air exchange by means of mechanical ventilation in houses, oces, hotels, cafés,
meeting halls and other mechanically ventilated premises as well as utilization of extract air heat energy to warm up supply puried air.
The unit is designed for ceiling mounting, the VUE2 200 P model is designed for ceiling as well as for wall mounting.
The unit is rated for continuous operation.
Transported air must not contain any ammable or explosive mixtures, evaporation of chemicals, sticky substances, brous materials,
coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust, pathogenic
germs).
PURPOSE
THE UNIT MAY NOT BE OPERATED BY CHILDREN OR PERSONSWITH REDUCED PHYSICAL,
MENTAL OR SENSORY CAPACITIES, OR LACKING THE APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED
PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE UNIT INSTALLATION SITES MUST PREVENT ACCESS BY UNATTENDED CHILDREN.

UNIT DESIGN AND OPERATING LOGIC
The unit has the following operating logic:
Warm stale extract air from the room ows to the unit, where it is ltered, then air ows through the heat exchangers and is exhausted
outside by the extract fan. Clean cold air from outside is moved to the supply lter. Then ltered air ows through the heat exchangers and is
moved to the room with the supply fan.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up. Heat recovery minimizes thermal en-
ergy losses and space heating expenses in cold seasons.
The polymerized cellulose heat exchangers are used to recover both sensible and latent energy contained in the extract air and transfer it
to the cold intake air ow from outside.
The polymerized cellulose heat exchangers act as air moisture accumulators when the ambient air humidity is too low or as supply air de-
humidiers if the ambient humidity is high. Due to the excellent water-absorbing properties of the heat exchanger material the unit drainage
is not required. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.
Freeze protection
The heat exchanger freeze protection function of the unit is implemented with a thermostat installed in the exhaust air duct downstream
of the heat exchanger. In case of a freezing danger the supply fan is turned o and the heat exchanger is warmed up with warm extract air
ow. The recommended thermostat operating temperature is +3 °C (factory setting).

MOUNTING AND SETUP
UNIT MOUNTING
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY
TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS.
DISTANCE TO THE UNIT
When selecting the installation site provide minimum allowed distances to the unit.
min 50 mm min 200 mm
min 250 mm
min 50 mm min 200 mm
min 250 mm
min 50 mm
While mounting the unit provide enough access for maintenance or repair work.
When selecting a mounting location of the unit provide free opening of the service panel.
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect a straight air duct section on both
sides of the unit while mounting.
Minimum straight air duct length:
• equal to 1 air duct diameter on intake side
• equal to 3 air duct diameters on outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects, e.g. by covering the spigots with apro-
tecting grille or other protecting device with mesh width not more than 12.5 mm to prevent uncontrollable access to the fans.
While installing the unit ensure convenient access for subsequent maintenance and repair. The unit must be mounted on a plane surface.
Mounting of the unit to an uneven surface can lead to the unit casing distortion and operation disturbance.
SUSPENDED MOUNTING OF THE UNIT
The unit is suspended with the suspension brackets (included in
thedelivery set) or belts.
Attach two mounting brackets within a distance of 400 mm away
from each other using dowels with screws or self-tapping screws (not
included in the delivery set) depending on the type of the surface.
When attaching the mounting bracket consider the surface material
and the unit weight.

Loosen the three-sided thumbscrews. Set the unit thumbscrews into the mating cutouts in the mounting brackets as it is gured below. Then
tighten the three-sided thumbscrews to x the unit.
Mounting using belts
The unit is suspended with the belts which must be selected to match the unit weight. The belt must have an opening or a hook to x
thethree-sided thumbscrews to the unit.
Remove all the three-sided thumbscrews from the unit for suspended mounting by means of belts. Then insert them into a mounting
opening or a belt hook. Fix the belts as necessary and screw the three-sided thumbscrews back to the unit.
Example of a suspended mounting is gured below.

CONDENSATE DRAINAGE
The unit is equipped with drain pans designed to remove condensate formed in the process of heat exchangers operation.
Connect the drain pipes, the U-traps and the sewage system with plastic or rubber pipes for condensate disposal arrangement. The pipe
slope downwards must be at least 3°.
Before starting the unit ll the system with water and check that the U-trap is always lled with water. Check for any obstructions to the
free ow of water into the sewage system to prevent condensate accumulation inside the unit, which may cause equipment failure and water
ingress into the premises.
