Manual KVBF

10.3 Assembly
Before delivery, each fan is examined in the factory.
After removing the packaging and before the start of assembly, you must:
• establish any possible transport damage,
• examine manually whether the fan wheel runs freely,
• examine the standard distance between the blade tip and the housing and
• check that no condensation has formed.
DANGER! Move the rotor of the fan by hand before you install it in order to check whether it
moves freely. Please pay attention that the xing screws of the fan can stick
out of the casing.
Attention should be paid on this especially!
DANGER! Risk of injuries if the safety directives are not observed.
In assembly, please observe the general occupational safety directives!
DANGER! Risk of injury if the fan falls down!
During assembly, secure both the assembly area and also the premises for any prepa-
rations against access by unauthorised persons.
DANGER! Risk of injuries from electric shocks!
Switch the energy supply off before you make the electric connection of the fan.
Make sure that the energy supply cannot be switched on again prematurely.
The electrical installation may only be done by trained personnel.
DANGER! Risk of injuries from rotating parts!
Rule out any risk by undesired switching on of the fan or undesired contact with the
rotor during assembly.
