LONG TERM BLOWER STORAGE Instructions
5. General Motor Procedure:
If the motor is not put into service immediately, the motor must be stored in a clean, dry,
warm location. Minimum temperature of 50°F. (10°C,). Several precautionary steps must be
performed to avoid motor damage during storage.
a) Use a “Megger” each month to ensure that integrity of the winding insulation has been
maintained. Record the Megger readings. Immediately investigate any significant drop in
insulation resistance.
b) DO NOT lubricate the motor bearings during storage. Motor bearings are packed with
grease at the factory.
c) If the storage location is damp or humid, the motor windings must be protected from
moisture. This can be done by applying power to the motor’s space heaters, (IF
AVAILABLE) while the motor is in storage. If the motor does not have space heaters,
storing it in a damp or humid location will, very quickly, cause internal corrosion and
motor failure which is not warranted.
NOTE
For specific storage instructions, for the actual motor and any accessory parts that were
supplied, refer to the manufacturer’s instructions.
