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
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
they always lock the machine (with all rotating
with
rotating
bodies
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.
