STORAGE
When a unit is not going to be in service for an extended period of time, certain procedures should be followed
to keep the unit in proper operating condition:
• Plug all piping
• Rotate fan wheel monthly and purge bearings once every one to three months (depending on environment)
• Energize fan motor once every three months
• Store belts flat to keep them from warping and stretching
• Store unit in location without vibration
• Cover unit with tarp to protect from dirt and moisture
• After storage period, purge grease before putting fan into service
NOTE!
Do not cover unit with a black tarp, this would
promote condensation.
NOTE!
Improper storage which results in damage to the
unit will void the warranty.
