Receiving
Greenheck models 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 the manufacturer. 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 self-supporting 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°F 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 3-1/2 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
