Outdoor storage is not recommended. Aside
from all the possibilities of external weather conditions,
erection conditions, environmental conditions etc.,
which can affect an idle machine, variations in
temperature and humidity can cause condensation
throughout the unit, producing rust and corrosion on
metal parts as well as deterioration of the electrical
insulation. If outdoor storage cannot be avoided, contact
the factory through the nearest General Electric office
giving full information on the circumstances and
explaining steps to be taken to protect the machine.
Failure to protect the machine may invalidate the
warranty.
The storage facility must provide protection from
contact with rain, hail, snow, blowing sand or dirt,
accumulations of ground water, corrosive fumes and
infestation by vermin or insects. Continuous or severe
intermittent floor vibration should be avoided. Electrical
service for space heater and illumination should be
provided. There should be fire detection and a fire
fighting plan. The machines must not be stored where
they are liable to accidental damage or exposed to weld
spatter, exhaust fumes or dirt. If necessary, erect suitable
guards or separating walls to provide adequate
protection. Avoid storage in a atmosphere containing
corrosive gases, particularly chlorine, sulphur dioxide
and nitrous oxides.
The machine in storage must be protected from
moisture condensation on the windings and other critical
parts. To prevent condensation, energize the machine's
space heaters to keep the machine temperature above the
room temperature by at least 3C. During the periods of
extreme cold or rapid temperature decrease, the space
heaters may not be adequate to maintain this
temperature differential. Therefore, safe supplementary
space heating may be required.

The machine in storage should be inspected
periodically and inspection records maintained. The
following tests and inspections are designed to reveal
deterioration or failure of protective systems (shelter,
coatings and temperature control), of the machine
without delay. Inspect the storage area for compliance to
the above criteria and inspect the stored machine for the
following:
1. Physical damage.
2. Cleanliness.
3. Signs of condensation.
4. Integrity of protective coatings.
5. Condition of paint - discoloration.
6. Signs of vermin or insect activity.
7. Satisfactory space heater operation. It is
recommended that an alarm system be in place to
operate on interruption of power to the space heaters.
Alarms should be responded to immediately.
8. Record the ambient temperature and relative
humidity adjacent to the machine, the winding
temperature (utilizing the RTD's), the insulation
resistance and the polarization index. Refer to the
section entitled Insulation Resistance on page 15 for
information on determining the insulation resistance and
polarization index.
Experience has shown that adequate precautions
during storage will avoid costly deterioration of parts
and lengthy maintenance procedures at installation and
start-up
