STORAGE
When a fan is not going to be in service for an extended amount of time, certain procedures should be followed
to keep the fan in proper operating condition.
• Rotate fan wheel monthly and purge bearings once every three months (If storage of fan is in a humid,
dusty or corrosive atmosphere, purge the bearings once a month).
• Cover unit with tarp to protect from dirt and moisture (Note: do not use a black tarp as this will promote
condensation)
• Energize fan motor once every three months
• Store belts flat to keep them from warping and stretching
• Store unit in location which does not have vibration
• After storage period, purge grease before putting fan into service
Improper storage which results in damage to the fan will void the warranty.

REPORT ANY DAMAGED EQUIPMENT TO THE SHIPPER IMMEDIATELY!
All units are shipped on a skid or packaged to minimize damage during shipment. The transporting carrier has
the responsibility for delivering all items in their original condition as received from Greenheck. The individual
receiving the equipment is responsible for inspecting the unit for obvious or hidden damage, recording any
damage on the bill of lading before acceptance and filing a claim (if required) with the final carrier. Some
accessory items are stored inside the unit during shipping. Care must be taken during installation to prevent
damage to units.
