Fan Housing Installation
Lower Vektor fan housing into place. Allow gasket to
become compressed before securing to plenum.
Install moly-coated 316 stainless steel screws (provided)
in all holes in plenum cap.
Fans – Rigging, Lifting and
Installation
Prior to setting fan(s) on plenum, place 1/4-inch thick
x 3/4-inch wide EPDM gasket around the perimeter of
top edge of BAP where fans mount, adhesive side down
(gasket provided).
Fans - Rigging and Lifting
Fans are to be rigged and moved by the lifting points
provided or by the skid when a forklift is used. Location
of lifting points varies by model and size. Handle in such
a manner as to keep from scratching or chipping the
coating. Damaged finish may reduce ability of fan to
resist corrosion. See coating repair section of this manual
for details involving touch-up of damaged surfaces.
Scratches and chipped paint are not covered by warranty.
Vektor-MD fans size 40 and larger and all MH and MS
fans are shipped with the nozzle separate from the main
housing. For these sizes the nozzle should be lifted
separate from the fan. For MD models with the nozzle
attached the main fan housing can be lifted using the
lifting points on the nozzle.
• Use standard lifting and rigging practices.
•
ALL
lifting points on each component must be
utilized at the same time.
•
Fan to be kept level during lifting and installation.
CAUTION
Fans should never be lifted by the shaft, motor, motor
cover or accessories.

Securing the Bypass Air Plenum
After bypass air plenum (BAP) has been lifted into
position, plenum should be secured to roof curb,
structural steel or concrete pad. Bottom of the BAP
has a removable skirt section with pre-punched
holes. These holes will align with holes and nutserts
in the roof curb if the roof curb was provided by same
manufacturer. If the roof curb is from another supplier
use the holes in the skirt as a template.
Allow gasketing to compress before securing. When
securing BAP to curb install using moly-coated 316
stainless steel screws (provided) in all holes.
If BAP is not being mounted on a roof curb, it can
be secured to either structural steel or concrete pad.
Full perimeter and cross support under the BAP is
required. Method used to secure the BAP to either
structural support(s) or concrete pad is determined by
site or structural engineer. If BAP is welded to support
structure, repair the area where coating was burnt off.
See coatings repair section of this manual for details
involving touch-up of damaged surfaces.
Mounting the BAP to roof curbs from manufacturers
other than Greenheck Fan Corporation or not
following proper mounting instructions may impact fan
performance and void warranty.
