The unit consists of a protecting internal grille with a decorative panel, a cartridge, an air duct and a protecting external
ventilation grille or a hood.
The cartridge is the basic functioning part of the unit.
The cartridge consists of a fan, a regenerator and two filters
that ensure rough air filtration and prevent ingress of dust

The internal grille is equipped with manually actuated shutters which can close the air duct during the unit standstill.
The external protective grille on the outer wall prevents
ingress of water and foreign objects into the unit.

Unit operation modes
The unit has two ventilation modes:
Regeneration. The unit operates in reversible mode with
heat and humidity regeneration in two cycles, 70 seconds
each.
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.
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.

5.2. UNIT MOUNTING
!
min 3 °C
Read the user’s manual prior to mounting the unit.
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.
EQ 2
1. Prepare holes for the air ducts.
Prepare a round core hole 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.
2. Prepare air ducts of required length.
Measure the wall thickness.
Cut the air duct so it fits flush on both sides of the wall.
Min. length is 350 mm.
Cut the air duct on the outher side which don´t have
cable grooves.
Insert the air duct into a prepared hole in the wall.
The cable grooves must be located on inner wall side.
When making holes, we recommend ensuring that the
power cables and control cables are in order.
Recommended hole dimension;
When using an external metal grille: Ø170 mm
When using an external plastic grille: Ø180 mm
Polystyrene wedge
Fill the gap between the air duct
and the wall with mounting foam
or similar.

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 soundabsorbing layer length calculated from the flange
width of the square inner grille.
Insert the cartridge during adjustment in the air duct.
L = 40 mm
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!
The adjustment of the sound-absorbing layer length
for the unit with an external grille
Mark the sound-absorbing layer at the end of the air
duct (1).
From the mark (1) measure 55 mm and make a new
mark (2). Cut the excessive part of the soundabsorbing layer.
Insert the adjusted and ready sound-absorbing layer
into the air duct.
No glue is required for fixation!
The adjustment of the sound-absorbing layer length
for the unit with an outer hood (accessories)
Mark the sound-absorbing layer at the end of the air
duct (1). Cut the excessive part of the sound-absorbing
layer.
Insert the adjusted and ready sound-absorbing layer
into the air duct.
No glue is required for fixation!

4. Insert the air duct in the wall.
Install the air duct with the sound-absorbing layer with
minimum slope 3° downwards using polystyrene wedges.
Fill the gaps between the wall and the opening with a
mounting foam.
Make sure that moisture cannot permeate into the
opening in the external wall. Use a suitable sealant.
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.
