6 Commissioning
Caution
• If strong vibrations occur during
commissioning, immediately increase
or decrease the fan speed until the
vibrations are decreased. Continuous
strong vibrations can cause damage
to components.
• Do not increase the fan speed to a
higher rpm value than the maximum
value that is given on the name plate.
The commissioning report is found at www.systemair.com.
6.1 To do before the
commissioning
• Make sure that the installation and electrical connection
are correctly done.
• Visually examine the product and accessories for damage.
• Make sure that the safety devices are correctly installed.
• Make sure that there are no blockages in the air inlet and
the air outlet.
• Make sure that installation material and unwanted objects
are removed from the product and the ducts.
6.2 To do the commissioning
1 Set the installed safety switch in the OFF position.
2 If it is possible to get access to the fan impeller, do the
steps that follows:
a. If it is necessary, remove parts of the installation.
b. Turn the fan impeller by hand and make sure that it
turn easily.
c. Record the result in the commissioning report.
3 Make sure to turn the product in a direction that agrees
with the related arrow on the product.
a. Record the result in the commissioning report.
4 If you removed parts of the installation to get access to
the fan impeller, install the removed parts again.
5 Set the installed safety switch in the ON position.
6 Start the product.
7 Set the minimum operation speed.
8 Increase the operation speed gradually to the maximum
operation speed.
a. Examine the vibrations in the casing and the bearing
areas at all speed levels.
b. Make sure that the vibrations agree with the specifi-
cations in DIN ISO 14694.
c. Make sure that none of the speed levels cause un-
wanted noise in the product.
d. Record the result in the commissioning report.
9 Record the necessary data in the commissioning report.
7 Operation
Caution
EC motors must be set to ON/OFF via
the control input. To stop the product via
mains supply decreases the life time of
the motor. Systemair recommends to
install external speed controller for easy
access to control the input signal.
7.1 To start a product with an EC
motor
1 Make sure that the 0–10 V signal is set to “0” with the
speed controller.
2 Set the installed safety switch in the ON position and wait
5 seconds.
3 Adjust the fan speed with the 0–10 V signal speed con-
troller. If an external speed controller is not installed, ad-
just the fan speed directly with the integrated
potentiometer.
7.2 To start a product with an AC
motor
1 Set the installed safety switch in the ON position.
2 Install the external speed controller. Refer to the instruc-
tion manual for the installed speed controller.
7.3 To stop the product
1 Set the installed speed controller in the OFF position.
Refer to the instruction manual for the installed speed
controller.
2 Set the installed safety switch in the OFF position.
7.3.1 To stop the product in an
emergency
• Set the installed safety switch in the OFF position.
