♦ After commissioning, start with shorter maintenance intervals.
♦ If no damage occurs, adjust the maintenance intervals up to the those stated in the operating
instructions.
♦ Responsibility for gradual adaptation is with the system operator.

Pay attention to the safety references and preconditions as in normal maintenance. For the following activities and
functions, contact Systemair:
• complete overhaul of motors
• replacement of bearings
• re-winding of motors
• monitoring of condition
• vibration analysis
After 20,000 hours of operation or 5 years of normal operation
♦ Check the condition of the shaft sealing rings and shaft bearings and take action if necessary.
After 30,000 to 40,000 hours of operation
