Receiving / Unpacking / Handling / Storage; Inspection And Maintenance During Storage - Greenheck Vektor-H Installation, Operation And Maintenance Manual

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 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° 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.
2 Laboratory Exhaust System
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.
