2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than maximum
cataloged fan rpm. Adjustments to fan speed
significantly effects motor load. If the fan RPM is
changed, the motor current should be checked to
make sure it is not exceeding the motor nameplate
amps.
5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.
6. Verify that the power source is compatible with the
equipment.
7. Never open access doors to a duct while the fan is
running.
DANGER
Always disconnect power before working on or near a
fan. Lock and tag the disconnect switch or breaker to
prevent accidental power up.
CAUTION
When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.

Receiving
Greenheck model Vektor-H and Vektor-HS fans are
thoroughly inspected, test run at the factory, and
shipped on a skid or packaged to minimize damage
during shipment. The transportation carrier has the
responsibility of delivering all items in their original
condition as received from Greenheck. The individual
receiving the equipment is responsible for inspecting the
unit for obvious or hidden damage and recording any
damage on the bill of lading before acceptance of the
equipment. All claims (if necessary) shall be filed with
the final carrier.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received, including accessory
kit containing gasketing, etc. If any items are missing,
report shortages to your local representative to arrange
for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together
due to availability of transportation and truck space.
Confirmation of shipment(s) must be limited to only
items on the bill of lading.
Handling
The Vektor-H and Vektor-HS laboratory exhaust system
is shipped in subassembly sections for easy rigging
and installation. Depending on the fan size, the sections
can include: Blower Assembly, Stack Extension, and
Discharge Nozzle.
The Vektor-H and Vektor-HS are designed to be selfsupporting and standing (without the use of guy wires)
when assembled per the instructions provided within
this manual. All subassembly sections have lifting lugs
as shown.
Storage
Fans are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the fan and accessories while in storage. The
manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a
convenience to the user.
INDOOR
The ideal environment for the storage of fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain, or snow. Temperatures should
be evenly maintained between 30° and 110°F. (-1°C
and 43°C). Wide temperature swings may cause
condensation and “sweating” of metal parts. All
accessories must be stored indoors in a clean, dry
atmosphere.
Remove any accumulations of dirt, water, ice or snow
and wipe dry before moving to indoor storage. To avoid
“sweating” of metal parts allow cold parts to reach room
temperature. To dry parts and packages use a portable
electric heater to get rid of any moisture build up. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.
The unit should be stored at least 3½ in. (89 mm) off the
floor on wooden blocks covered with moisture proof
paper or polyethylene sheathing. Aisles between parts
and along all walls should be provided to permit air
circulation and space for inspection.
OUTDOOR
Fans designed for outdoor applications may be stored
outdoors, if absolutely necessary. Roads or aisles for
portable cranes and hauling equipment are needed.
The fan should be placed on a level surface to prevent
water from leaking into the fan. The fan should be
elevated on an adequate number of wooden blocks so
that it is above water and snow levels and has enough
blocking to prevent it from settling into soft ground.
Locate parts far enough apart to permit air circulation,
sunlight, and space for periodic inspection. To minimize
water accumulation, place all fan parts on blocking
supports so that rain water will run off.
Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles.
Fan wheels should be blocked to prevent spinning
caused by strong winds.
Inspection and Maintenance during
Storage
While in storage, inspect fans once per month. Keep a
record of inspection and maintenance performed; see
backcover.
If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the wheel by hand ten to fifteen
revolutions to distribute lubricant on motor and
bearings. If paint deterioration begins, consideration
should be given to touch-up or repainting. Fans with
special coatings may require special techniques for
touch-up or repair.
Machined parts coated with rust preventive coating
should be restored to good condition promptly if signs
of rust occur. Immediately remove the original rust
preventive coating with petroleum solvent and clean
with lint-free cloths. Polish any remaining rust from
surface with crocus cloth or fine emery paper and oil.
Do not destroy the continuity of the surfaces. Wipe
clean thoroughly with Tectyl® 506 (Ashland Inc.) or
the equivalent. For hard to reach internal surfaces or
for occasional use, consider using Tectyl® 511M Rust
Preventive or WD-40® or the equivalent.

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.
General Information
To ensure a successful installation, the instructions in
this manual should be read and adhered to. Failure to
comply with proper installation procedures may void the
warranty.
Unit and System Identification Tags
Each fan has a permanently affixed manufacturer’s
engraved metal nameplate containing the model
number and individual serial number.
The tag shown
is an example of
an identification
nameplate on the
fan. The information
provides general
details about
the fan, as well as containing specific information
unique to the unit. When contacting your Greenheck
representative with future needs or questions, please
have the information on this label available. Tags are
mounted in an area which is clearly visible, usually on
the side of the fan cabinet.
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.
Prior to fully assembling and installing the Vektor-H or
Vektor-HS fans, inspect bypass air plenums and the fan
assembly to make sure they are in working order.
Electrical Disconnects
All fan motors should have disconnects located in close
visual proximity to turn off electrical service. Service
disconnects shall be locked-out when maintenance is
being performed.
Moving Parts
All moving parts must have guards to protect personnel.
Refer to local codes for requirements as to the number,
type and design. Fully secure fan wheel before
performing any maintenance. The fan wheel may start
“free wheeling” even if all electrical power has been
disconnected. Before the initial start-up or any restart,
check the following items to make sure that they are
installed and secure.

cataloged fan rpm.
t "EKVTUNFOUTUPGBOTQFFETJHOJmDBOUMZBGGFDUTNPUPS
load. If the fan RPM is changed, the motor current
should be checked to make sure it is not exceeding
the motor nameplate amps.
Guards (Motor Cover, Weatherhoods)
Do not operate fans without proper protective devices in
place. Failure to do so may result in serious bodily injury
and property damage. Check local codes to ensure
compliance for all protective devices.
Air Pressure and Suction
In addition to the usual hazards associated with rotating
machinery, fans also create a dangerous suction at the
inlet. Special caution needs to be used when moving
around a fan, whether it is in operation or not. Before
start-up, make sure the inlet area is clear of personnel
and loose objects.
Pre-Installation Information
Before installation, it is important to be certain the
mounting surface will bear the operating weight of the
unit. For proper unit operation, it is also important that it
be operated in a completely level position.
For further details on safety practices involving
industrial and commercial fans, please refer to AMCA
Publication410.
