Fan; Drive - TCF ZAE Series Installation, Operation And Maintenance Manual

4.6.2.

Fan

Before start-up, carry out the following checks:
- make sure that the fan wheel is functioning correctly by
turning it manually
- check that any safety clamps fitted to prevent damage
during transportation have been removed from the
dampers (fig. 31).
4.6.3.

Drive

Before starting the Air Treatment Unit, check:
- the tension of the "V" belts (section 5.5.4.)
- that the pulleys are aligned (section 5.5.4.)
- that the dowels, shown in fig. 32 in their possible
installation positions, are doing their job of securing the
pulleys to the hubs.
4.6.4. Noise level
The computation and control of noise emissions has today
become particularly important, both during the design
and installation phases.
The sound pressure values of our machines are indicated
In our technical catalogues or can be supplied directly by
our Technical Department according to the requested air
moving characteristics.
Being therefore aware of the sound emissions produced
by the Unit, the Designer must make sure that, in treated
environments, maximum values laid down by current
regulations are not exceeded.
It must however be stressed that every environment has
its own acoustic characteristics which can considerably
affect sound pressure values of mechanical ventilation
systems. THE NOISE LEVEL DATA SUPPLIED BY US
SHOULD CONSEQUENTLY BE CONSIDERED AS A
CALCULATION BASE
CONSIDERATIONS WHICH TAKE INTO ACCOUNT THE
SYSTEM AND BUILDING STRUCTURE AS A WHOLE.
