DESIGN AND FUNCTIONING
The ventilator consists of an indoor assembly unit with a decorative front panel, a cartridge, an air duct with a sound absorbing mat and
an outer ventilation hood.
Cartridge is the basic functioning part of the unit. It consists of a fan, a regenerator and two filters that ensure primary air filtration and
prevent ingress of dust and foreign objects into the regenerator and the fan.
The indoor unit is equipped with a manually operated rotary air damper.
Attention!
During closing of air damper the ventilator continues to run, but the air flow is closed.
The protecting grille or ventilation hood must be installed on the outer wall to prevent ingress of water and foreign objects into the
ventilator.
