Seguire le norme di sicurezza durante le procedure di approntamento e il funzionamento della ventola.
La procedura di installazione della ventola è la seguente:
Controllare che il motore non sia sotto tensione (vedi Fig. 3.1);
Segnare i punti di montaggio delle staffe sulla superficie portante (unità) (vedi Fig. 3.2);
Forare e fissare la ventola sulle staffe con mezzi adeguati (ad es. tasselli a espansione) (vedi Fig. 3.3);
Collegare le condotte alla ventola (vedi Fig. 3.4).
The duct fans have been designed for installation in round air ducts. The fans are installed in portions of ducts. The enclosure
is equipped with mounting brackets to ensure the correct positioning of the fan. When the fan is installed on flexible joints,
connect it to the main structure using supports, suspension joints or brackets.
The fan can be installed in any position considering the direction of the air flow (as indicated by the arrow on the fan enclosure).
To reduce the aerodynamic resistance resulting from air flow turbulence for a straight section equal up to 1 duct diameter
on the fan inlet side and one equal to 3 duct diameters on the fan outlet side, these sections must be free of filters or other
devices.
Ensure adequate access for fan maintenance.
After opening the packaging and before installation:
Carefully read the specific instructions for the installation, operation and maintenance of the fan.
Check that the fan is intact and was not damaged during transport.
Follow the safety rules during the fan set-up and operating procedures.
The fan installation procedure is the following:
Check that the motor is not powered (see Fig. 3.1);
Mark the mounting points of the brackets on the load-bearing surface (unit) (see Fig. 3.2);
Drill holes and secure the fan on the brackets using appropriate devices (e.g. expansion plugs) (see Fig. 3.3);
Connect the ducts to the fan (see Fig. 3.4).
