Short Term Storage
If the equipment is not put into immediate use it should 
be stored in a clean, dry location. For all Weather 
Protected Type II (WPII) motors, motor heaters should 
be activated upon arriving at the jobsite to prevent con-
densation. This is required for warranty considerations.
Care should be taken to keep the equipment covered 
when moving from a cold location to a warm location, 
otherwise condensation may occur. If condensation 
does occur, and the equipment is moist, allow it to dry 
thoroughly before applying power.
Long Term Storage
1. Cover machined metal parts with weatherproof cover, 
but leave ventilating area exposed.
2. Make certain unpainted portions are covered and re-
touch any scratches or fl aked areas.
3. If condensate plugs or drain plugs have been used, 
make sure they are operative.
4. Cover completely with plastic cover and insert silica-
gel bags inside the cover for moisture control.
5. If motor is equipped with space heaters make sure 
space heaters are properly connected and operative. 
The motor interior temperature should be maintained 
approximately 10 °F (5.6 °C) above ambient.
6. For all Weather Protected Type II (WPII) motors, motor 
heaters should be activated upon arriving at the jobsite 
to prevent condensation. This is required for warranty 
considerations.
7. A systematic inspection and maintenance schedule 
should be established. If rotating apparatus is to be 
stored for 6 months or longer, it should, in addition to 
the minor precautions above, be given a megger test ev-
ery 3 to 6 months. A minimum reading of 10 megohoms 
is recommended. A record of insulation values, temper-
ature, time, humidity and length of voltage application 
should be recorded to show winding conditions prior to 
start up.
8. If windings are designed for outdoor operation, they 
will not be affected by extreme or sudden temperature 
changes or inclement weather in general. However a 
weather proof cover with provisions for adequate venti-
lation should be used to guard against intrusion of salt, 
dust, or other abrasive or corrosive material.
9. It is recommended that the rotor be turned every 
month to redistribute the lubricant in the bearings and 
oil or grease be added every 6 six months.
10. Preferably, storage would be in a warehouse or en-
closed building but the same precautions should be 
followed.
Lubrication
Refer to manufacturer’s lubrication instructions.
