VENTO Eco / VENTO Eco2
UNIT OPERATION MODES
The unit has two ventilation modes:
Ventilation. The unit operates in permanent supply or extract mode at set speed. In case of two units operating in this mode one unit
operates in supply and the other one in extract mode.
Regeneration. The unit operates in reversible mode with heat and humidity regeneration in two cycles, 70 seconds each.
Cycle I.
As warm stale extract air flows through the ceramic regenerator, it heats up and moisturizes the regenerator and transfers up to 97 %
of heat energy.
In 70 seconds as the ceramic regenerator gets warmed the unit is switched to supply mode.
Cycle II.
Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the room
temperature.
In 70 seconds as the ceramic regenerator gets cooled down, the unit is switched to air extract mode and the cycle is renewed.
In this operation mode, in case if two units are installed each of them operates two cycles in opposite phases.
While one unit operates in air supply mode the other one operates in air extract mode.

UNIT MOUNTING
READ THE USER’S MANUAL PRIOR TO MOUNTING THE UNIT.
WARNING!
DO NOT BLOCK THE AIR DUCT OF THE INSTALLED UNIT WITH DUST ACCUMULATING
MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC. AS IT PREVENTS AIR
CIRCULATION IN THE ROOM.
1. Prepare holes for the air ducts.
Prepare one or two round core holes in the outer wall, depending on the unit equipment.
For efficient operation of the ventilation system it is recommended to install the units as far apart from one another as possible.
While preparing core holes it is recommended to make preparations for layout of the power cable and other required cables.
The core hole size and minimum distance to a mounting surface, for example, a wall, ceiling or a window as well as the minimum
distance between the units are shown below.

Measure the wall thickness B.
The air duct length is calculated as L = B + A, where A
means an air duct segment that protrudes in the outer
wall to enable installation of the external grille or the outer
ventilation hood. For details, see the table below.

Cut the air duct to the length L, without consideration to the
cable groove.
Insert the air duct into a prepared hole in the wall.
The cable grooves must be located on inner wall side.
The air duct end on the indoor side must be flush with the
inner wall side.

3. Install the sound-absorbing layer in the air duct. Prior to installation adjust its length with respect to the dimensions of the cartridge,
external grille or the outer ventilation hood as well as the internal square or round grille.
This example shows adjustment of the sound-absorbing layer length calculated from the ange width of the square inner grille.
Insert the cartridge during adjustment in the air duct.
The distance L from the edge of the air duct is equal to the
width of the flange of the inner grille.
For a square grille L = 40 mm (1 9/16") for a round one
L = 20 mm (13/16")
During adjustment of the insulation layer length cover the air
duct and the cartridge with the internal grille.
Roll the sound-absorbing layer to match the air duct diameter
with the protecting paper layer outside and insert the roll in
the air duct against stop.
Do not remove the paper layer!

To enable easy installation of the cartridge in the air duct cut
out a recess in the mounting foam layer on the side of the
cable installation parallel to the groove in the air duct.
For freedom of placement of the cable in the groove without
any damage to the cable insulating material, cut off the excess
of the mounting foam.
5. Install the cartridge in the air duct.
6. Connect the socket connector from the control panel in compliance with the external wiring diagram. Connect the socket connectors
of the cartridge and the control panel.
