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:
IP20 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.

DESIGN AND OPERATING PRINCIPLE
UNIT OPERATION LOGIC
Heat Recovery mode: warm stale extract air from the room flows into the unit, where it is filtered by the extract filters, 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 filters. Then the air flows through the heat exchangers and is directed to the room with the supply fan. Heat energy
of warm extract air is transferred to clean intake fresh air from the outside and warms it up. 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.
Summer Cooling mode: the bypass damper is opened, the intake air that is supplied to the premises bypasses the heat exchanger and
its temperature doesn’t change.
The units have three frost protection modes (danger of freezing appears when the exhaust air temperature downstream of the heat
exchanger is lower than +5 °C and intake air temperature upstream of the heat exchanger is lower than -3 °C):
— periodically the supply fan is turned off
— with the bypass
— with the electric preheater (if the unit is equipped with a preheater)
Mode selection and settings are described in the control system user’s manual.

The unit is equipped with a service door for technical and maintenance operations. Opening the service door while the unit is running
will lead to its shut down. The unit design enables installation of a bypass duct with a bypass damper to route the intake air stream
without contacting the heat exchanger.
The unit is equipped with differential pressure switches to control filter clogging.
Additional equipment for the unit is available on a separate order.
• Humidity sensor. The unit with an installed humidity sensor maintains a set indoor humidity level. 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 mode.
• CO2sensor. Measures the level of concentration of carbon dioxide in the room and generates a signal that controls the performance
of the fan. Air flow control based on CO2concentration is an efficient energy saving solution.
• VOC sensor. Qualitative assessment of air saturation with contaminants (cigarette smoke, exhaled air, solvent and detergent vapours).
• The sensor sensitivity can be adjusted with regards to the expected maximum level of air pollution. Enables on-demand ventilation
which results in considerable energy savings as air is exchanged only upon reaching the preset level of pollution.

TECHNICAL MAINTENANCE
Maintenance operations of the unit are required 3-4 times per year. They include 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. Clean the filter with a vacuum cleaner or replace it with a new
one. To clean the filters, remove them from the unit. For new filters,
contact the Seller.
2. Heat exchanger maintenance (once per year).
Some dust may accumulate on the heat exchanger 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.
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.
To access the fans, remove the protection plates (secured with the
screws).
Clean the fans with a soft cloth, brush, or using compressed air.
Do not use water, aggressive solvents, or sharp objects as they
may damage the impeller.
4. 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.
