The ventilator consists of the telescopic air duct with adjustable length regulated by position of the inner air duct inside the outer air
duct, the ventilation unit and the ventilation hood.
Two fi lters and the ceramic regenerator are located inside the inner duct of the telescope.
The fi lters are designed to purify supply air and prevent foreign object ingress to the regenerator and the fan.
The ventilator generates a sound alarm reminding to clean or replace the fi lter every 90 days.
The ceramic regenerator uses extract air heat energy to warm up supply air fl ow.
The regenerator is equipped with a pull cord inside to facilitate its withdrawal from the ventilator. The regenerator is installed on an
insulation material used as a sealant as well.
The ventilation unit must be installed on inner side of the wall. The ventilation unit is equipped with automatic shutters that shut the
air duct off during the ventilator standby and prevent air back draft.
The ventilation hood must be installed on outer side of the wall to prevent ingress of water and other objects to the ventilator.

Mounting plate
A mounting plate for installation the ventilation
unit on the wall and connecting the ventilator to
the power mains.
Ventilation unit
Is used to generate air flow by the fan. The deco-
rative grille protects the fan against foreign ob-
jects ingress from the premises.
The ventilation unit is equipped with automatic
shutters opening when the ventilator is on and
closing when it is off, thus preventing back air
flow.
Ventilator is off - shutters are closed
The ventilator has three ventilation modes:
• Natural air supply - the ventilator is used for natural ventilation, the fan is not activated.
• Supply - the ventilator supplies fresh air to the premise no matter of CN7 jumper position.
• Ventilation - the ventilator operates in permanent supply or extract mode at set speed depending on CN7 jumper position.
• Regeneration - the ventilator operates in reversible mode with heat and humidity regeneration.

DESIGN AND OPERATING LOGIC

Outer ventilation hood
Prevents direct water and foreign objects in-
gress to the ventilator.
Distance ring
Is used as a support for the filters and the regen-
erator in the inner air duct.
Filter
Designed to purify supply air flow and prevent
dust and foreign objects ingress to the ventila-
tor. Prevents regenerator clogging.
Ceramic regenerator
Provides extract air heat energy regeneration to
warm up supply air flow.
Filter
Designed to purify supply air flow and prevent
dust and foreign objects ingress to the ventila-
tor. Prevents regenerator clogging.
Air flow rectifier
Eliminates air turbulence, thus reducing noise
level.
