•
Type A: open intake and outlet.
•

•
Type C: intake connected to a pipe and open outlet.
•
Type D intake and outlet connected to a pipe
Depending on the applications that the client intends to use the fan for and on the type of installation
chosen, the following safety shields must be fitted:
•
Type A installation: fixed shields at the intake and outlet;
•
Type B installation: fixed shields at the intake;
•
Type C installation: fixed shields at the outlet
When installing the unit, the distance needed at the service side for maintenance or repair is
В +50cm ( В – width of the unit). If the unit is equipped with multiple leaf dampers, please, make sure
the actuator (electric motor) or the manual control mechanism (important when building the duct
system) is easily accessible.
The installer should ensure that the ceiling structure is capable of supporting the weight of the
device to be installed, bearing in mind that it is a dynamic load.
The machine may include different signage pictograms, which must not be removed.The signs are
divided into:
•
Forbidden signs: Do not carry out repairs or adjustments during operation.
•
Danger signs: Indicates the presence of elements with tension inside the container on
which the notice is displayed.
•
Identification signs: EC card, indicating the manufacturer’s address and product
details.The EC marking indicates that the product conforms to European Community
standards.
5.2 Maintenance
Periodical checks must be carried out in order to ensure the correct work of the air handling unit.
It is an owner’s or an owner’s representative duty to keep all the information and documentation,
supplied with the unit.
5.3 Air duct system
When connecting the air handling unit to the duct system, is recommended the use of flexible
connections (fig.16), in order to avoid transmission of noise and vibration. It is obligatory to build a
ground connection between both flanges of the flexible connection. Connection between two flanges
is made by clamps and bolts. The distance between two bolts should ~150mm (fig.17).
