To install motor protection for
AC motors

• If the product has an built in motor protection, reset by dis-

connecting the product from power for 60 seconds.

• If the motor has temperature monitors such as thermal

contacts (TK) or thermistors lead out into the terminal box,
these must always be connected in the control circuit us-
ing appropriate motor protection.

• Make sure that an overheated motor cannot start again

automatically when it becomes cool.

• Install the motor cables and the temperature monitor apart.

• If the motor does not have temperature monitors, install a

motor protection switch.

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.
