was delivered complete and undamaged. Losses or
damage recognizable upon delivery must be noted and
noted in detail on the delivery receipt. When recording
loss or damage, please be specific and avoid general
terms such as “box damaged” or “torn”. Please check size,
model and accessories too.
The unit must be stored in a dry and clean place protected
from frosting and magnetic fields, in its original packaging
until installation. In case of long-term storage or inactivity,
the unit must be protected from dust and moisture, and

6 INSTALLATION
During installation leave a free space to maintenance and
service. The access panels have to be opened for that
purpose (see free space reccomendation for servicing) and
to allow internal components to be removed for cleaning or
service (for ex. heat exchangers, fans, filters).
The unit is designed to provide mechanical ventilation with
heat recovery. The unit can operate with constant speed,
constant air flow or constant pressure, with the related
accessories. The unit is equipped with high efficiency heat
exchanger (up to 95% heat can be recovered) and with
low consumption EC motors fans.
The unit is for indoor installation. Operation temperature is
0-40°C (without ambient frosting). For external temperature
lower than -10°C the preheater is recommended. Do not
continuously use the unit in the presence of water vapor
(both internal and external to the unit). For high humidity
atmosphere inquiry the manufacturer. The automatic frost
protection is provided by flow imbalancing. Electronic
controlled bypass damper is provided to supply filtered
outside fresh air. Bypass opens and closes according to
the setting available on touch screen (KTS) or can be
driven by an external input. Min external temperature to
close bypass and threshold internal temperature to open
bypass can be set. High surface area washable G4 filter
(coarse) (on return side) and F7 ePM1 55%(fresh side)
are standard. Clogged filter alarm is by pressure sensors
as standard.
Installing conditions and aeraulic system if not adequate
or properly planned can affect the nominal performances
of the unit.
