6.1 SAFETY CONTROL
Before starting the fan check that there are no abnormal devices
inside the fan. Check that the fan is installed correctly and
according to the instructions. Check that all necessary safety
equipment is installed and can be used.
The fan shall only be started when all essential instructions are
followed and all essential installations have been checked.
6.2 TEST RUN
Start the fan to check that the rotation direction is correct and
that the impeller rotates correctly. Check that there are no ab-
normal noises and the fan runs smoothly.
The roof fan does not need any special service. However, it is
necessary to clean the fan impeller especially when the air is not
clean. This helps to avoid vibrations in the impeller.
If there is an abnormal noise coming from the motor bearings, the
motor and impeller or the complete fan unit shall be replaced.

ried out only by authorized personnel.
