Receiving
This product may have been subject to road salt during
transit. If so, immediately wash off all visible white
residue from all exterior surfaces. Upon receiving the
product, check to ensure all line 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 if any damage is
detected,
do not refuse shipment . The customer shall
make notation of damage (or shortage of items) on the
delivery receipt and all copies of the bill of lading which
should be countersigned by the delivering carrier. If
damaged, immediately contact your manufacturer’s
representative. Any physical damage to the unit after
acceptance is not the responsibility of the manufacturer.
Handling
Units are to be rigged and moved by the lifting brackets
provided. Location of brackets varies by model and size.
Handle in such a manner as to keep from scratching or
chipping the coating. Damaged finish may reduce ability
of unit to resist corrosion.
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.
Storage
Units 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 unit 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.
The ideal environment for the storage of units and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain, or snow. Units designed for outdoor
applications may be stored outdoors. All accessories
must be stored indoors in a clean, dry atmosphere.
Indoor
Maintain temperatures evenly to prevent condensation.
Remove any accumulations of dirt, water, ice, or snow
and wipe dry before moving to indoor storage. To
avoid condensation, allow cold parts to reach room
temperature. 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. Clearance should be provided to permit air
circulation and space for inspection.
Outdoor
The unit should be placed on a level surface to prevent
water from leaking into the unit. The unit should be
elevated so that it is above water and snow levels.
Ensure sufficient support to prevent unit 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
unit 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.
Inspection and Maintenance
While in storage, inspect units 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 fan 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. Units 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. Wipe thoroughly 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 units are removed from storage to be installed
in their final location, they should be protected and
maintained in a similar fashion until the equipment goes
into operation.
Prior to installing the unit and system components,
inspect the unit 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.
