ENGLISH
Noise level
Depending on the model of the fan, its power, size
and revolutions the noise level can be different.
You can find the noise level information, for every
models, on technical catalogues or website.
Connecting to Air system ducts
Connecting to the ducts is possible thanks:
- Air inlet: connecting the duct to the
circular flange
(on the inlet side);
- Air outlet: using optional joints (not
supplied)
In any cases of connection, It is always advised to
use elastic joints.
It is not recommended that you use ducting with
bends in the immediate vicinity of the appliance, as
the flow of air generated requires a straight section at
least 3 or 4 times the equivalent diameter of the duct
to reduce the vertical air flow to normal.
Motorfan balancing
The appliance is statically and dynamically balanced
to level 6.3 according to ISO 1940 standards,
however the use of vibration dampers on the base is
recommended.
Protection against unvolountary accident
Preventing accidents with rotating bodies is
necessary. In the following cases, you must install
protection grids:
- Air inlet: without any inlet duct
connected;
- Air outlet: without any outlet duct
connected.
Note: in any cases of connection (inlet side or outlet
side), preventing accidents is always necessary
(checking the minimal lenght of the duct).
Start up
Once completing the installation, checking the
missing friction on rotating bodies is always advised.
Also double check no external element or left over
material from the installation is inside the fan or its
ducts. Check also that the air inlet and outlets are
clear. Note: in case of adjustable air grids, need to
verify the correct opening and functioning (in order to
avoid over consuptions).
First start up
for a short time (5-10 minutes) check only:
- the correct direction of the rotation;
- the correct missing of abnormal noises;
- the correct missing of abnormal frictions.
Note: in case of wrong direction of the rotation, it
could be solved checking the right electrical
connection.
Second start up
for a longer time (120-180 minutes) check nominal
values:
- the maximum speed;
- the maximum absorbed current and power
consuption;
- the correct functioning of protections/safety
devices: testing them many times and verifying that
14
they always lock the machine (with all rotating
bodies) and lock the power supply to the product.
You need to repeat the test 3 times at least (with a
positive feedback).
NOTE Some models, equipped with an heavy
impeller, need a long time for the start up. In these
cases, you need to check it at the starting.
IMPORTANT: You need to verify, with tool, the real
consumption, and you need to compare nominal
values with rating
consumptions: need to turn of the fan, immediately.
An excessive consumption could be caused by a
possible defect of the fan, motor, friction, or an
electrical connection error, but the main cause
usually is a wrong adaptation of the installation due to
excess or faulty charge.
On the contrary, the air flow should be obstructed
with the regulating door if existing or by placing any
element that can obstruct partly the suctioning inlet.
In this latest case, amongst anything check that no
elements are loose that can be suctioned inside the
fan. Once readjusted the installation check again that
the consumption is within the range. After this
readjustment is achieved, the fan should be started
up and work correctly without any problems.

Signs on the appliance

A number of signs may be present on the appliance
and these must never be removed (Fig 6).
