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 Greenheck Representative.
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
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 in such
a manner as to keep from scratching or chipping the
coating. Damaged finish may reduce the ability of the
fan to resist corrosion. Fans should never be lifted by
the shaft, fan housing, motor, belt guard, windband or
accessories.
Storage
• Rotate fan wheel monthly and purge bearings once
every three months
• Energize fan motor once every three months
• Store belts flat to keep them from warping &
stretching
• Store unit in location which does not have vibration
• After storage period, purge grease before putting
fan into service
If storage of fan is in a humid, dusty or corrosive
atmosphere, rotate the fan and purge the bearings once
a month. Improper storage which results in damage to
the fan will void the warranty.
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.
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
