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 
page 15.
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 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.

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 the Traffic Department. 
If damaged upon arrival, file 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, including accessory 
kit containing flex connector, 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

Fans 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 each piece in such a manner as to keep 
from scratching or chipping the coating. Damaged 
finish may reduce ability of fan to resist corrosion. 
See coating repair section of this manual for details 
involving touch-up of damaged surfaces.
Fans should never be lifted by the shaft, fan housing, 
motor, belt guard, weatherhood, windband or other 
accessories.

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°F (

-1°C

) and 

110°F (

43°C

) (wide temperature swings may cause 

condensation and “sweating” of metal parts). All 
accessories must be stored indoors in a clean, dry 
atmosphere.
