Conservation / storage of the compressor
If the compressor is not to be used for an extended period of time, we recommend the
following conservation work to be carried out before the storage:
• Run the compressor at 200 bar for approx. ten minutes
• Drain warm oil and replace by new oil.
• Open filling valves and run the compressor for a few minutes.
• Stop the compressor and open the drain valves.
• Close filling valves.
• Open the final filter housing and lubricate the O-Ring with a food grade grease or silicone grease.
• Store the compressor in a cool dry place free from dust and contamination. A cover is
recommended as long as condensation can be avoided.
De-conservation, commissioning
After the compressor has been stored, the following steps are to be taken:
• Replace the final purification filter.
• Check oil level, replace oil if necessary. Fuel Driven Units only: Fill up fuel tank to top level to
avoid corrosion.
• Inspect the condition of the v-belts, replace if necessary
• Inspect the filling hoses visually for signs of deterioration, replace as necessary.
• Fix filling valves by e.g. cable strips to avoid whipping around wildly. Open filling valves.
• Open the filling valves and run the compressor for approx 10 minutes with the filling valves
open.
• Close the filing valves and allow the compressor to build up to working pressure.
• Check the correct safety valve setting and/or pressure switch setting (option).
• Check all connections and pipe work for leaks, retighten if necessary.
Once the above steps are completed to satisfaction, the unit is ready to use.
