STORAGE
When a unit is not going to be in service for an extended amount of time, certain procedures should be
followed to keep the fans in proper operating condition.
• Rotate fan wheel monthly and purge grease from bearings once every three months
• 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 from fan bearings before putting fan into service
If storage of unit 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 unit or components will void the warranty.
