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.

Maintenance/cleaning
Check the filter from time to time and, if necessary,
replace it. Non reconditionable filters, which have to
be replaced when the loss of pressure is 1.5 times
above the loss that occurs when the filter is cleaned.
Clean the filter with mechanical means, a vacuum
cleaner or compressed air.
