8.12 CALIBRATION OF FAN FLOW RATES
Fan speeds are calibrated at the factory as follows, which statistically corresponds to the most common
applications:
• Minimum speed: 40% of the maximum power of the fans.
• Average speed: 60% of the maximum power of the fans.
• High speed: 80% of the maximum power of the fans.
The flow rate indicated in the flow/head graphs on the data sheets corresponds respectively to 50% ,72% and
100% of the maximum power. To adjust the factory calibration values to the actual needs of the system, act on
the potentiometers placed on the control board, one per Speed.
Each potentiometer changes the speed of both fans in the unit
8.13 START-UP AND TESTING
Before starting the machine check that all the closing panels are in their position and well tightened with their
own screws.
Check that all connections (hydraulic, electrical and ducting) are installed correctly and that all
indications on labels and user manual are observed.
Starting and testing of the units should preferably be carried out in conjunction with the testing and starting of
the entire ventilation system, which also extends to the ventilation network, radiant panels and
dehumidification, if they are present.
The test must be carried out by qualified personnel and adequately trained also for subsequent maintenance.
