4.4.6 Incorrect transport
NOTE
Property damage due to in-
correct transport
If the fan is lifted via the ring
screw on the motor, it can
tear out. The fan then falls
and is badly damaged.
Do not use the ring
screw on the motor for
transport. This is only in-
tended for the assembly
and disassembly of the
engine.
Damage to the frequency inverter
(only for IK devices)
NOTE
Material damage due to in-
correct handling
The frequency inverter can
be quickly damaged if the fan
is handled incorrectly.
Do not use the fre-
quency inverter as a
climbing aid or foot-
board
Do not install load-car-
rying equipment on the
frequency inverter
4.5 Storage
The following points must be considered
so that the fan, which is not used for an
extended period, remains functional:
•
The fan
-
if possible, in original packag-
ing
-
in a closed room,
-
store dry, dust-free, and vibra-
tion-free
•
Suction and pressure connection
must be closed
•
Storage temperature range from -
20°C (-4°F) to +60°C (+140°F)
•
After a storage period of 12 months
or more, the motor bearings must
be checked before the fan installa-
tion
•
During commissioning with 50% of
the frequency let the fan run for 2
minutes, so that the ball bearing
grease can mix after a long stand-
still or storage time under low load.
•
Devices may be stored for a maxi-
mum of 2 years
