utilized to prevent condensation from accumulating in the motor. This heating should
maintain temperature at a minimum of 9ºF (5ºC) above the ambient temperature of
the room, keeping it from dropping below the dew point where condensation could
form inside the motor.
• Rotate the motor shaft monthly to redistribute bearing grease.
Start-Up Preparation After Prolonged Storage

pre-shutdown procedures.
• Fans and motors should be thoroughly inspected and cleaned to restore them to pre-
storage condition.

protective coverings.
• For units stored prior to installation, conduct rigging procedures as directed
in the unit’s

Representative.
• Perform an insulation test to ensure satisfactory insulation resistance.
• Conduct full start-up procedure as stated in “Start-Up” on
