VUE: energy recovery air handling unit
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).

TECHNICAL DATA
The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to
60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.
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 should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a minimum
(20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage electronic
components. Never use the unit for dehumidification, for example, of new buildings.
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.

The service side of the unit is equipped with a detachable inspection hatch on manual bolts for filter and heat exchanger cleaning and
replacement operations. The plate enthalpy cross-flow heat exchanger is made of polymerized cellulose.
The control unit is positioned inside the unit casing . The power cable and grounding cables are connected to the control unit via the
cable gland located at the side of the unit. The unit is equipped with a controller and a power cord with a Euro Plug XP.
Warm stale extract air from the room flows into 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 the outside flows into the unit, where it is cleaned by the
supply filter. Then the air flows through the heat exchanger and is directed 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 provides both heat and humidity recovery.
In warm seasons the heat exchanger operates to cool down and dehumidify the supply air. In cold seasons the heat exchanger
operates to warm up supply air and humidify it. Water vapour from the humid extract air is condensed and absorbed by the heat
exchanger plates. The recovered humidity and heat are transferred to the supply air flow. The air streams are fully separated within the
heat exchanger and the microbes and smells are isolated.
LEFT-HANDED AND RIGHT-HANDED MODIFICATIONS
The figure below shows the arrangement of spigots for left- and right-handed modifications. Choosing the right arrangement can

The provide heat exchanger freeze protection during the cold season, the unit is equipped with a thermostat that is installed in the
exhaust air duct downstream of the heat exchanger. The Defrosting mode is activated when the exhaust air temperature is +3 ˚С.
After temperature increase the unit returns to the previous operation mode.
In the Defrosting mode the supply fan is turned off and the heat exchanger is warmed up with warm extract air flow.
To set the thermostat threshold value, turn the control knob to the desired position.
The recommended thermostat operating temperature is +3 °C (factory setting).

MOUNTING AND SETUP
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
The unit is designed for suspended ceiling mounting with anchor threaded rods, nuts and anti-vibration rubber.
Fasteners for fan 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 a qualified specialist! Before mounting make sure the casing does not
contain any foreign objects (e.g. foil, paper).
The minimum distance between the unit and the ceiling should be 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 the 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 fan, the spigots may be covered with a protecting grille or other protecting device with mesh
width not more than 12.5 mm.

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE
OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE
PROTECTION
TECHNICAL MAINTENANCE
The unit must undergo technical maintenance 3 to 4 times a year.
They include general cleaning of the unit and the following operations:
1. Filter maintenance (3-4 times per year).
Dirty filters increase air resistance in the system and reduce supply air volume.
Replace the filters when they get dirty but not less than 3-4 times per year.
To replace the filters, remove the inspection hatch located on the service panel and
remove the dirty filters, then install the new filters and the inspection hatch in the
reverse order. For new filters, contact the Seller.
2. Heat exchanger maintenance (once a year).
Some dust may accumulate on the heat exchanger block even in case of regular
maintenance of the filters. To maintain high heat exchange efficiency, periodical dry
cleaning is recommended. Use a vacuum cleaner with a narrow nozzle.
3. Fan maintenance (once a year).
Even in case of regular maintenance of the filters, some dust may accumulate inside
the fans and reduce the fan performance and supply air flow.
Clean the fans with a soft brush or cloth.
Do not use water, aggressive solvents, or sharp objects as they may damage the
impeller.
4. Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air
ducts which reduces the unit capacity.
Duct maintenance means regular cleaning or replacement.
5. Control unit maintenance (if necessary).
The control unit is positioned inside the unit casing.
For accessing the control unit remove the fixing screws on the service panel and remove it.
