PURPOSE
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.
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafés, 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 supply air.
THE UNIT MAY NOT BE OPERATED BY CHILDREN OR PERSONS WITH 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 CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED ACCESS
BY UNATTENDED CHILDREN.
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).

**Humidity sensor
Control panel
Power cable with a plug
The service panel is equipped with a detachable access door with manual bolts for cleaning or replacement of the filters and heat exchanger. The
control unit is positioned inside the unit casing. The power and the ground cable are to connect to the control unit through the airtight electric lead-in
in the unit casing side.
The plate enthalpy cross-flow heat exchanger is made of polymerized cellulose.
*The bypass damper is open or closed depending on operation mode of the unit.
**At the request of the customer the unit can be equipped with a humidity sensor. The humidity sensor is purchased separately as an accessory.
The unit with an installed humidity sensor maintains a set indoor humidity point. As the extract air humidity rises above the set point, the system
automatically switches to the maximum speed. As the humidity drops down below the set point the unit returns to the previous operation mode.
Installation and connection of the humidity sensor is carried out on site by the service technician.

UNIT OPERATION MODES
Heat recovery: warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the heat
exchanger and is exhausted outside with the extract fan.
Cold fresh air from outside flows into the unit, where it is cleaned in the supply filter. Then the air flows through the heat exchanger and is moved
to the room with the supply fan.
Supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. The air flows are fully
separated while flowing through the heat exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.
The enthalpy heat exchanger allows to recover humidity as well as heat. In the summer period, the supplied fresh air is cooled and dried by the heat
exchanger, in the winter period it is heated and moisturized. The water vapour is devaporated from the stale wet air and absorbed with heat exchanger
plates. The released heat and moisture are transferred to the supply air. The transferring of dirt, odours and microorganisms from one air flow to another
is excluded.
EXTRACT AIR

INTAKE AIR
EXHAUST AIR
Defrosting mode: to prevent the heat exchanger freezing in the cold season the unit has an automatic Defrosting mode according to the freeze
protection temperature sensor readings in the exhaust air duct downstream of the heat exchanger. The unit switches to the defrosting mode at the
extract air temperature +3 °C. As the temperature rises the unit returns to the previous mode. Only the extract fan operates in the defrosting mode, the
supply fan is switched off.

INTAKE AIR
EXHAUST AIR
Summer Cooling mode: in the units with a bypass damper, the part of the intake air that is supplied to the premises bypasses the heat exchanger,
the bypass damper is opened and the outdoor air supply temperature changes slightly.

MOUNTING AND SETUP
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED
AND HAVING THE REQUIRED TOOLS AND MATERIALS.
HUMIDITY SENSOR MOUNTING
The humidity sensor is not included in the scope of delivery and can be ordered separately.
The humidity sensor must be installed prior to unit mounting. Unit mounting sequence:
• Remove the mounting screws of the service side panel of the unit and take it off.
• Install the humidity sensor into the mount from the side of the extract air duct and connect the humidity sensor contact socket to the respective
contact socket coming from the control unit, refer to the External wiring diagram.
• Install the sensor cover back.
UNIT MOUNTING
The unit is designed for ceiling mounting with anchor threaded bolts, nuts and vibration-absorbing rubber. Fasteners for unit mounting are not
included in the delivery set and should be ordered separately. While choosing fasteners consider the material of the mounting surface as well as the
weigh of the unit, refer to the Technical Data section. Fasteners for unit mounting should be selected by the service technician.
Before mounting make sure that the casing is free of any foreign objects like film or paper.
While installing the unit ensure convenient access for subsequent maintenance and repair.
Minimum required distance from the unit to the ceiling is at least 20 mm.
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect the straight air duct section to the spigots
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. To prevent uncontrollable access to the fans the
spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.
