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.

DESIGN AND OPERATING PRINCIPLE

VUTR 250/350/650 P/P2/PE/P2E EC

The unit has the following operating principle: Warm stale extract air from the room flows to the unit, where it is filtered. Then the air is moved through the rotary heat exchangers and is exhausted outside with the exhaust fan. Clean cold air from outside is moved to the supply filter. Then filtered air flows through the rotary heat exchanger where it is warmed up to the pre-set temperature value 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 losses of electric energy and space heating expenses in cold seasons and cooling expanses in warm seasons. An exhaust kitchen hood may be optionally connected to the unit. The kitchen hood should be equipped with an air valve. The valve closes the exhaust duct when the kitchen hood is switched off.

The unit is a framework construction made of rigidly fixed panels. The panels are made of aluzinc and galvanized sheets, internally filled with a heat- and sound-insulated layer of mineral wool. The air handling unit is equipped with quick-detachable service panels for filter replacement. Route power and ground cables through the screwed cable glands to connect those to the terminal block located in the control unit. The wiring diagram is shown on the control unit side panel.

INSTALLATION AND SET-UP
READ THE USER'S MANUAL PRIOR TO MOUNTING THE UNIT.
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS.
While mounting the unit provide enough access for maintenance or repair work. The minimum recommended clearances between the unit and the adjoining walls are given in the figure below.

min 600

Before starting the unit make sure that the rotary heat exchanger cells are clean and free from damage. Check the belt tension. The tension force is regulated by the spring on the motor suspension mount. The unit may be suspended on a threaded rod that is fixed inside a dowel or may be rigidly fixed on a horizontal or vertical plane.

To get the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section to the spigots on both sides of the unit while installing. 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. While installing the unit, ensure convenient access for subsequent maintenance and repair. Fasteners for ceiling mounting are not included into 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.
HUMIDITY SENSOR MOUNTING The humidity sensor is not included in the delivery set and should be ordered separately. It must be installed in the exhaust duct upstream of the heat exchanger. Undo the screws on the service panel and remove it. Screw the humidity sensor to the exhaust air duct wall. Connect the humidity sensor connector to the cable of the control unit (installed by the manufacturer).

CONNECTION TO POWER MAINS

POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER'S LABEL.

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.
· The unit is rated for connection to 230 V/50 (60) Hz power mains according to the wiring diagram. · The connection must be made using insulated conductors (cables, wires). The actual wire cross section selection must be based
on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation method. · The external power input must be equipped with a QF automatic circuit breaker 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 trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit (refer to the "Technical data" section or on the unit label). The recommended trip current of the circuit breaker is the next current in the standard trip current row following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set and can be ordered separately.

TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
Maintenance operations of the unit are required 3-4 times per year. Maintenance includes general cleaning of the unit and the following operations: 1. Filter maintenance. Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning not less than 3-4 times per year. When 3 000 operating hours have elapsed, the unit controller generates the filter replacement or cleaning alert. Clean or replace the filters and reset the hour meter. Vacuum cleaning is allowed. After two consecutive cleanings filters must be replaced. For new filters contact the Seller. Sequence of filter removal: 1. Disconnect the unit from power mains. 2. Unscrew the triangular screws holding the service covers. 3. Remove the service covers. 4. Remove the plugs. 5. Pull the filters to remove. 6. Install the filters in the reverse order.
2. Heat exchanger maintenance (once per year). Some dust may accumulate on the heat exchanger block even in case of regular maintenance of the filters. To maintain the high heat recovery efficiency, regular cleaning is required. To clean the heat exchanger, remove it from the unit and clean the heat exchanger by using compressed air or a vacuum cleaner. After cleaning re-install the heat exchanger into the unit. Sequence of heat exchanger removal: 1. Undo the 8 screws and remove the service panel. 2. Clean the heat exchanger with a compressor or a vacuum cleaner.

www.ventilation-system.com

VUTR 250/350/650 P/P2/PE/P2E EC

3. Fan maintenance (once per 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 cloth or brush. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller. 4. Supply air flow control (twice per year). The supply duct grille may get clogged with leaves and other objects reducing the unit performance and supply air delivery. Check the supply grille twice per year and clean it as required. 5. Ductwork system maintenance (once in 5 years). Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts, which leads to air pollution and reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
