II. RECEIVING, STORAGE, HANDLING AND UNPACKING
A. Receiving
Each shipment should be carefully inspected upon arrival. Any damage should be reported
promptly to the carrier and a claim filed. The nearest GE sales office can provide additional
guidance.
B. Storage
If the machine will not be put into service immediately, certain precautions should be taken
to protect the machine while in storage. It is recommended that the machine be placed
under cover in a clean, dry location.
During storage, windings should be protected from excessive moisture by some safe and
reliable method of heating, such as space heaters, to keep the temperature of the
windings a few degrees above the temperature of the surrounding air. It is recommended
that the machine be inspected at periodic intervals, the windings meggered, and a log kept
of pertinent data. (Refer to Operation section.) Any significant drop in insulation resistance
should be investigated.
Precautions are taken by the factory to guard against corrosion. The machined parts are
coated to prevent rust during shipment. If the equipment is to be stored, examine the parts
carefully for rust and moisture and re-coat where necessary.
Grease-lubricated machines have the bearings greased at the factory with the cavity
approximately 50% full.
Rotate the shaft of all two-bearing machines 10-20 revolutions at two-month intervals.
C. Handling
Before lifting the motor, ensure that the eyebolt shoulder is completely seated against the
motor frame boss. Eyebolt should only be tightened by hand.
The angle of lift must not exceed a 15
o
angle with the shank of the eyebolt.
Warning
The lifting lugs or eyebolts on the motor are designed for handling only the motor. They are not
to be used to lift the motor plus additional equipment such as pumps, compressors, or other
driven equipment. In the case of assemblies on a common base, the lugs or eyebolts provided on
the motor are not to be used to lift the assembly and base. The assembly should be lifted by a sling around
the base or by other lifting means provided on the base. In the case of unbalanced loads (such as couplings or
other attachments), additional slings, or other effective means should be used to prevent tipping. Failure to
observe these precautions may result in damage to the equipment, injury to personnel, or both.
