Small units should be handled carefully and lifted only by the base, never by
the shaft, coupling, motor, or housing. Large units should be lifted by the base
or by the lifting eyes. Precautions should be taken to avoid dropping or jarring
the equipment as this can cause damage to the shaft or wheel, which is not visi-
bly noticeable, but can cause vibration problems.

Fans and motors should be mounted on structurally sound foundations.
Concrete is the best, however, other types designed properly are acceptable.
Equipment should be leveled on the foundation and shimmed or grouted in
place. This will prevent putting the fan structure into a bind by bolting it down
on an uneven surface.
As a general rule, if vibration isolators are used, the fan should first be bolted to
a structural steel base and the isolation takes place between the structural steel
base and the foundation. This prevents the fan base from floating due to uneven
weight distribution and/or drive forces when mounted directly to vibration iso-
lators.

TIP: Extended Storage
- Units
that will be held in storage for a
period of up to two (2) years
should have special provisions so
operation-readiness can be
maintained. Motors should be
equipped with internal space
heaters kept on continuously.
Units should be crated and cov-
ered with polyethylene film. In
addition, impellers should be
hand-rotated once a month. For
best results, keep the units shel-
tered in a cool, dry location.
