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).

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.

EXHAUST AIR
Defrosting mode: to prevent the heat exchanger freezing in the cold season the unit is equipped with a thermostat 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. 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 temperature threshold turn the control knob to the according position. The recommended thermostat operating temperature is
+3 °C (factory setting).

MOUNTING AND SETUP
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND
HAVING THE REQUIRED TOOLS AND MATERIALS.
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 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.

CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
INSTALLATION SHALL ONLY BE PERFORMED BY A PROFESSIONAL ELECTRICIAN QUALIFIED FOR
UNASSISTED OPERATIONS WITH ELECTRICAL INSTALLATIONS UP TO 1000 V AFTER CAREFUL STUDY
OF THE PRESENT USER’S MANUAL.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.
ANY INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT IN WARRANTY LOSS.
The unit is rated for connection to single-phase ac 230 V / 50 Hz.
Connect the unit to power mains using the pre-wired power cord with the Euro Plug XP. Connection is made through the external automatic circuit
breaker with magnetic trip integrated into the fixed wiring system. The position of the automatic circuit breaker must ensure free access for quick
power-off of the unit. The trip current must be not less than the consumption current, refer to Technical data.
The speed controller is connected to the unit be the manufacturer using the cable of 3 m length. The reconnection of the controller is allowed if the cable
length needs to be changed. Technical requirements to a cable: type – 2x0.5 mm2, length – up to 10 m.
To access the control unit, remove the mounting screws of the service side panel of the unit and take it off.

UNIT CONTROL
The unit is operated with the speed controller. The speed controller is included in the scope of delivery. The mounting recommendations, the wiring
diagram and controller operation are given in the user’s manual of the speed controller.
TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY MAINTENANCE OPERATIONS.
THE CONTROL UNITMAINTENANCE MUST BEPERFORMED BY ANEXPERT QUALIFIED FORUNASSISTED
OPERATIONS WITH ELECTRICAL INSTALLATIONS WITH THE VOLTAGE UP TO 1000 V AFTER CAREFUL
READING OF THE USER’S MANUAL.
The unit must undergo technical maintenance 3 to 4 times a year. Maintenance includes
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. The filters
require replacing as they get contaminated but not less than 3–4 times per year.
To replace the filters, open the access door on the service panel and remove the dirty filters,
then install new filters and close the access door.
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 the high heat exchange efficiency, regular heat exchanger vacuum
cleaning using a crevice nozzle is recommended.
To replace the heat exchanger, open the access door and remove the dirty exchanger from the
unit. Then install new heat exchanger and close the access door.
For a new heat exchanger contact the Seller.
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. To access the control unit, remove the mounting screws of the service panel of the unit and take
it off.
