RECEIVING, HANDUNG
AND STORAGE
RECEIVING

The equipment should be placed under adequate cover immediately upon receipt as packing coverings are not suitable for out-of-doors or unprotected storage. This includes adequate protection from construction dirt, during and after installation. Each shipment should be carefully examined upon arrival. Any damage should be reported promptly to the carrier and to the nearest office of GE Motors.

HANDlING

Motors can be lifted by using hooks or slings in the lifting lugs on the frame. These lugs are designed to safely carry the weight of the whole machine. Blowers should be protected with spreader bars if necessary. Ventilating hoods may have to be removed to clear hooks. Do not lift the machine by the shaft extensions.
