Operational Use
The construction and a solid execution of the fan
guarantees its operational
use without con-
stant routine maintenance.
As inappropriate use is considered application of the fan that is in contradiction with
its purpose
(
see Section 2 of the present Use and Maintenance Manual
)
and when the
reservations of manufacturer
are not observed
(
see Section 3 of the Use and Mainte-
nance Manual
)
.
Consequences of improper use
:
–
breakage of bearings,
–
balance loss of the rotary elements,
–
vibrations,
–
deformations,
–
damages caused by friction.
In case
when any
defective device function is noticed
(
increased noise level, vibrations,
reduced efficiency), it is important to disconnect the fan from the power supply, and
to undertake its technical revision in order to spot the reason of the functional distur-
bance.
Typical
disturbances and their reasons are exposed in the Section 8 of the pre-
sent Use and Maintenance Manual
.
