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.
