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.
PURPOSE
The ventilator is designed to ensure continuous mechanical air exchange in flats, cottages, hotels, cafes and other domestic and public
premises. The ventilator is equipped with a regenerator that enables supply of fresh filtered air heated by means of extract air heat energy
recovery.
The ventilator is designed for wall flush mounting.
The unit 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 temperature in the room where the indoor unit of the ventilator is installed must be in the range from +1 ˚C to +40 ˚C with relative
humidity up to 60 %. The transported air temperature must be in the range from -15 ˚C to +40 ˚C.
The ventilator is rated as a class II electric appliance.
Ingress protection rating against access to hazardous parts and water ingress is IP24.
The unit design is constantly being improved, thus some models may be different from those described in this manual.

The ventilator consists of an air duct, a ventilation unit and an outer ventilation hood.
Two filters, a regenerator, a distance ring and two air flow rectifiers are installed in the air duct.
The air filters are designed to purify supply air and prevent foreign object ingress into the heat exchanger and the fan.
The regenerator utilises extract air heat energy to warm up supply air flow.
The regenerator is heat insulated with a specially designed insulating material.
The ventilation unit must be installed on inner side of the wall.
The ventilation hood must be installed on outer side of the wall. It is used for directed air discharge and prevention of ingress of water
and other objects to the ventilator.
The ventilator operates in two cycles, 70 seconds each.
CYCLE I. Warm stale extract air flows through the regenerator, which is gradually warmed up and moisturized. In 70 seconds as the
regenerator gets warmed up the ventilator is switched to supply mode.
CYCLE II. Fresh intake air from outside flows through the regenerator, absorbs accumulated moisture and is heated to a room temperature
due to the heat accumulated in the regenerator. In 70 seconds as the regenerator gets cooled down, the ventilator is switched to air
extract mode and the cycle is renewed.

INSTALLATION AND SETUP
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
DO NOT BLOCK THE AIR DUCT OF THE INSTALLED VENTILATOR WITH DUST
ACCUMULATING MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC.
AS IT PREVENTS AIR CIRCULATION IN THE ROOM.
1. Prepare a round core hole in the outer wall. The hole size is shown in the figure below.

2. Insert the air duct in the wall. For ease of installation use the foam wedges included in the delivery set. The air duct end must protrude
for the distance A that enables installation of the outer ventilation hood. The distance A is stated in the mounting instruction for the outer
ventilation hood.

While mounting the air duct be sure to provide the minimum slope
3 mm downwards from outside.
The air duct can be cut by calculating preliminary the required length
or after fixing the air duct on the wall (in this case, it is necessary to
have access to the outside part of the wall).
3. Install the assembled regenerator into the air duct.

4. Press the latches on the side surfaces of the decorative grille to
remove the front part of the fan.
5. Attach the mounting plate and mark the places for the dowels with a pencil or marker. Drill the holes and insert the dowels.
Then mount the mounting plate on the wall and install the rear part of the ventilation unit in the duct. Fasten the rear part of the
ventilation unit with the screws on the mounting plate.
6. Install the front side of the ventilation unit to its original
position and fix it with a screw using a screwdriver.

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.
The ventilator is rated for connection to single-phase AC 220…240 V/50 Hz power mains using a power cable with a plug installed at the
factory.
WARNING! The unit must not be connected through any type of speed regulators – thyristor, autotransformer, frequency, etc.
The ventilator must be connected to the stationary power supply via an integrated switch with a gap between the contacts at all poles
of at least 3 mm.
The unit is equipped with an electric motor, which has two fixed speeds. Switching from the first speed to the second is carried out only
by a standard pull cord switch.
