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.

GENERAL

Greenheck Energy Recovery units with Tempering are thoroughly inspected and test run at the factory. However, damage may occur during handling and shipping. Consequently, it is important to inspect the unit for visible and concealed damage before beginning installation. Report any damage to the shipper immediately. In addition, assure all accessory items are present. Some accessory items are stored inside the unit during shipping. Care must be taken during installation to prevent damage to units.
