DUCT INSTALLATION
Ductable outlet air connections
CHD – cassette units have primary air flow connection.
They are equipped with inlets for treated air on the corner of
the unit. This air is mixed with the untreated room air inside
the appliance.
The size and the location of the outlets is shown by the
drawings.
All air ducting departing from the fan-coil unit must fea-
ture thermal insulation to avoid condensation and drip-
ping water.
After duct insulation, complete the water and electrical
connections.
