COMMISSIONING AND SETTING
5.1 Preliminary precautions
Before starting fan, make sure that the electric motor and impeller assembly rotate freely and that there
is no object likely to be ejected by the turbine. The protection housings must be fastened to roof fan to
prevent any accidental contact with rotating parts.
The machine should be attached to its support before power is applied.
Switch on just an instant to check the turbine’s rotating direction.
WARNING: The impeller rotating direction must correspond to each speed in the direction indi-
cated by the arrow on the product. A centrifugal backward fan unit with an impeller that does not
rotate in the right direction still creates a flowrate and a low pressure in the duct. An incorrect ro
-
tating direction can lead to an abnormal overheating of the motor, resulting in its destruction and
cancelling our manufacturer’s warranty.
If the rotating direction is incorrect, cut off the electrical power supply, make sure no power is present,
Contact after-sales service. Do not modify wirings, as this might seriously damages the unit.
While running, make sure that the motor’s absorbed current is not more than 10% above the name plate
indicated current .
Once the roof fan is installed and the tests successfully completed, present the main points of the opera-
tion and maintenance manual to the user, and explain:
• How to start up and shut down.
• How to change the operating modes.
Then hand over to the user the technical manual of the roof fan and the mounted accessories so that he
can keep it handy to consult it at any time.
