7. HANDLING & STORAGE
Fans are delivered in packages in their boxes according to their models.Transport the fan to the place of
assembly in its original packaging. During motor and wire connections mustn’t be damaged. Load and unload
the fan carefully, in order to avoid possible damage. Use suitable lifting equipment. The fan should be stored
in a safe, clean, dry, vibration free, location. A regular monthly rapid spin of the impeller is recommended to
prevent grease hardening and possible brinelling of the bearings; the impeller should not be in the same
angular position after rotation.
When dismantling the crate to gain access to the fan assembly care should be taken to avoid injury from
sharp edges, nails, staples, splinters, etc.
8. MAINTENANCE
Periodically check the screw connections, coil resistance, function of the safety components and control
elements. Only clean the fan manually, with a vacuum cleaner or with compressed air. Before service,
maintenance or repairing, disconnect the electrical connections and the impeller is stopped. The fan must be
cleaned when needed, at least once per year to maintain the capacity. The fan bearings are maintenance-
free and should be renewed only when necessary. Cleaning should be done without dislodging or damaging
the impeller. Make sure that there is no unexpected noise from the fan.
