6. COMMISSIONING (SPECIALISTS)
CAUTION
Only qualifi ed specialists may commission the ven-
tilation system, otherwise there is risk of injury or
damage.
6.1. INSTRUCTIONS FOR COMMISSIONING
• Before commissioning, the system including all air li-
nes must be checked for possible pollution residues or
foreign bodies and cleaned.
• All electrical safety features are properly connected
and confi gured and ready for operation.
6.2. ADJUSTING FLOW RATES
The fl ow rates can be set according to curves or accor-
ding to differential pressure measured at the differential
pressure taps.
The condensate duct must be installed before adjusting
the fl ow rates. Check that the siphon has been fi lled with
water or that there is a dry siphon installed (optional ac-
cessory - 5800015700). There must be a water seal at the
condensate connection.
Check this and secure it.
6.2.1. Set nominal airfl ow rate (extract air)
according to curves

1. Remove screws Torx 10 (20) (Arrow 1).
2. Remove cover (21) (Arrow 2).
3. Set up power supply of the ventilation system.
4. Turn on fan speed V3 on the control panel, see page
30.

5. The nominal airfl ow volume (extract air) can be set
in accordance with the specifi cations using the cur-
ves with the potentiometer (27), see diagram on page
16.
In the factory setting, the potentiometer (27) is at Po-
sition 4. It must be set to the value of the curve that is
closest to the intersection point between the nominal
airfl ow rate needs and static pressure lost. Then, the
extract and supply airfl ows must be checked and if
needed a readjustment must be made with the poten-
tiometer (27) (extract air) and the potentiometer (28)
(supply air).
As an alternative, the fl ow rates can be set by measu-
ring the differential pressure or by the constant air-
fl ow module ServoFlow (optional accessory).
