Inspection And Maintenance During Storage - Greenheck SQ 60-75 Installation, Operation And Maintenance Manual

Receiving
Upon receiving the product check to make sure all items
are accounted for by referencing the bill of lading to
ensure all items were received. Inspect each crate for
shipping damage before accepting delivery. Notify the
carrier if any damage is noticed. The carrier will make
notification on the delivery receipt acknowledging any
damage to the product. All damage should be noted on
all the copies of the bill of lading which is countersigned
by the delivering carrier. A Carrier Inspection Report
should be filled out by the carrier upon arrival and
reported to the Traffic Department. If damaged upon
arrival, file a claim with carrier. Any physical damage
to the unit after acceptance is not the responsibility of
Greenheck Fan Corporation.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. 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
Move fan to desired location and determine position of
access panels, discharge and motor. Make sure the inlet
and outlet have at least 21/2 times the wheel diameter
(duct diameter) before any obstructions like an elbow
or transition. Attach the fan to a suitable framework
as specified; hanging or base vibration isolators are
recommended. See the SQ & BSQ Fan Dimensions table
on page 3 for physical dimensions, utilizing Figures 1 and
2. Mounting dimensions and vibration isolator centerline
information is provided on pages 4 and 5. The motor's
amperage and voltage ratings must be checked for
compatibility to supply voltage prior to final electrical
connection. Electrical lead-in wires are then connected to
the factory supplied safety disconnect switch. All wiring
must conform to local and national codes.
Fan 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 Storage
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° to 110°F (-1° to 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 buildup. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.
The unit should be stored at least 31/2 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 Storage
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.
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. 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 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. Thoroughly wipe clean
with Tectyl ® 506 (Ashland Inc.) or the equivalent. For hard
to reach internal surfaces or for occasional use, consider
using Tectyl 511M Rust Preventive, WD-40
®
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.
