REMOVING FROM STORAGE
As fans are removed from storage to be installed
in their final location, they should be protected and
maintained in a similar fashion, until the fan equipment
goes into operation.
Prior to assembly and installation of the Vektor fan
and system components, inspect the fan assembly to
make sure it is in working order.
1. Check all fasteners, set screws on the fan, wheel,
bearings, drive, motor base and accessories for
tightness.
2. Rotate the fan wheel(s) by hand and assure
no parts are rubbing. Access to the wheel is
obtained through a bolted panel located on the
side of the fan housing.
3. Ensure proper wheel settings for radial gap and
alignment. Refer to page 13.
Installation
Installations with inlet or discharge configurations that
deviate from this standard may result in reduced fan
performance. Restricted or unstable flow at the fan
inlet can cause pre-rotation of incoming air or uneven
loading of the fan wheel yielding large system losses
and increased sound levels.
System Identification Tags
Vektor fan systems may arrive in component pieces
due to shipping restrictions. Individual components
of a system have matching identification tags
which should be used to identify and assemble the
complete system.
Assembling systems
with different
identification tags
can cause reductions
in the fan(s)
performance.
