Connection and assembly
The FB filter must be installed on a ventilation line,
upstream
from
the
fan/heat
recovery
sistem,
upstream from the noise attenuator NA, and if
present, upstream from the air heater AH. To install
the air filter, it is sufficient to insert it into the tube (Fig.
1).
The appliance is connected to the system by means
of a forced insertion on two cylindrical fittings in
galvanised steel with circular rubber built-in "T" seals.
Leave sufficient space to allow the filter to be cleaned
or replaced.
