Long Term Storage
Requirements
1) Remove the condensation drain plugs from those units equipped with them and insert silica-gel into the openings.
Insert one-half pound bags of silica-gel (or other desiccant material) into the air inlets and outlets of drip-proof
type motors.
NOTE: The bags must remain visible, and tagged, so they will be noticed and removed when the
unit is prepared for service.
2) Cover the unit completely to exclude dirt, dust, moisture, and other foreign materials.
3) If the motor can be moved, it is suggested that the entire motor be encased in a strong, transparent plastic bag.
Before sealing this bag, a moisture indicator should be attached to the side of the motor and several bags of
silica-gel desiccant put inside the bag, around the motor. When the moisture indicator shows that the desiccant
has lost its effectiveness, as by a change in color, the bag should be opened and fresh replacement desiccants
installed.
Whenever the motor cannot be sealed, space heaters must be installed to keep the motor at least 10°F above
the ambient temperature.
NOTE: There is a potential for damage by small rodents and other animals that will inhabit
motors in search of warm surroundings or food. Due to this, a possibility of motor
winding destruction exists. Sealing motor openings should restrict access to the motor.
4) Rotate motor and compressor shafts several revolutions (approximately 6) per month to eliminate flat spots on
the bearing surfaces. If the compressor unit is installed, wired and charged with oil, open all oil line valves and
run the oil pump for 10 seconds prior to rotating the compressor shaft. Continue running the oil pump while the
compressor shaft is being turned to help lubricate the surfaces of the shaft seal.
