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.

Standard Fan Configurations

The following illustration identifies a typcial 
configuration of the Vektor-CD system. Greenheck 
also supplies custom configurations. Your system 
may not be depicted in the drawing shown. Refer to
