6. COMMISSIONING
6.1 Prior precautions
Shut off and disconnect the power supply before carrying out any work.
In case of work on the fan, the local on-off switch defined according to IEC947-3/695-2-1 must be open
and locked in this position (according to NF C 15-100).
6.2 Setting the volume-pressure curve
•
Put the switch-disconnector to the “OFF” position,
•
Set the desired airflow-pressure curve by turning the adjusting po
-
tentiometer referring to § "2.2 Aeraulic curves", page 5,
• In general, the curves included in the manual mean the speed can
be pre-selected but it must then be fine-tuned using the potentiome
-
ter based on on-site measurements (duct or in-/outlets, airflow, etc.),
• Switch the switch-disconnector to the “ON” position,
N.B.: the motor is stopped between positions “0” and “1” of the adjusting potentiometer.
Case of a remote control: please refer to § "5.8 REB ECOWATT

or CVF remote electrical connection",
