9 Maintenance
9.1 Preventive maintenance schedule
Safety precautions
• Before starting any maintenance or repairs, stop the compressor.
• Depressurize the air system as follows:
• Close the air outlet valve.
• Press the emergency stop button.
• On compressors equipped with Electronic Water Drains (EWD), press the
test buttons on top of the electronic water drains.
• Press the emergency stop button.
• Open the isolating switch (customer's installation) to switch off the voltage to the
compressor, and lock it (Lock Out - Tag Out procedure, LOTO).
• Repairs inside the speed regulation cabinet must only be carried out by Atlas
Copco.
• Wait at least 6 minutes before starting any electrical repairs as hazardous high
voltage remains on the condensers of the variable speed drive for 6 minutes after
switching off the voltage.
• The operator must apply all relevant safety precautions.
Service agreements
Atlas Copco Customer Centers have a range of service agreements to suit your needs:
• An Inspection plan
• A Preventive maintenance plan
• A Total responsibility plan
Contact your Customer Center to agree on a tailor-made service agreement. It will ensure optimum
operational efficiency, minimize downtime and reduce the total life cycle costs and ensure that all
warranties are validated.
Warranty-Product Liability
Use only authorized parts at the correct intervals (check with your local Atlas Copco Service center). Any
damage or malfunction caused by the use of unauthorized parts or unqualified personnel is not covered by
Warranty or Product Liability. In the event of any extended warranty, the end user must ensure that all
required maintenance actions are performed when indicated on the Elektronikon display (see table below)
or, alternatively, use an Atlas Copco Service agreement.
Service kits
Atlas Copco Customer Centers will be glad to provide you with a wide range of service kits. Service kits
comprise all parts needed for servicing components and offer the benefits of genuine Atlas Copco parts
while keeping the maintenance budget low.
