Receiving
Upon receiving the product check to ensure all items
are accounted for by referencing the delivery receipt or
packing list. Inspect each crate or carton for shipping
damage before accepting delivery. Alert the carrier
of any damage detected. The customer will make
a notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which
is countersigned by the delivering carrier. If damaged,
immediately contact your local representative. Any
physical damage to the unit after acceptance is not the
responsibility of the manufacturer.
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. Due to availability of
transportation and truck space all items for the unit may
not be shipped together. 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 3 times the wheel diameter
of straight duct before any obstructions like an elbow
or transition. Attach the fan to a suitable framework as
specified by others; hanging or base vibration isolators
are recommended. See Dimensional Data (page 3) for
physical dimensions. The motor's amperage and voltage
ratings must be checked for compatibility to supply
power prior to final electrical connection. Electrical lead-
in wires are then connected to the electrical wires run
to the external factory supplied junction box. All wiring
must conform to local and national codes.
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.
Storage Environment
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 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 3-1/2 inches (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.
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 in 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
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.
