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
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 label. In case of more 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
