Receiving

This product may have been subject to road salt 
during transit. If so, immediately wash off all visible 
white reside from all exterior surfaces. 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 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 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 or by the skid when a forklift is used. 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. Inspect interior of unit 
cabinet for any shipped loose items. 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.
