Instruction Manual Oil-Less Compressors
10. STORAGE, PRESERVATION
10.1. GENERAL
If the oil-less compressor is to be put out of service for more than six months, the unit should be preserved in
accordance with the following instructions:
Make sure the compressor is kept indoors in a dry, dust free room. Only cover the compressor with plastic if it is
certain that no condensation will form under the sheet. Nevertheless, the sheet should be removed from time to
time and the unit cleaned on the outside.
If this procedure cannot be followed and/or the compressor is going to be taken out of service for more than 2
years, please contact our Technical Service Department for special instructions.
10.2. PREPARATION
Before preserving the oil-less compressor unit, run it warm and when unit reaches the specified service pressure,
keep it running for approx. 10 minutes.
Then carry out the following:
- Check all pipes, filters and valves (also safety valves) for leakage.
- Tighten all couplings, as required.
- Continue to run
compressor for another 5 minutes at an operating pressure of 43 psi.
- On compressors equipped with a condensate drain valve, observe that condensate is drained automatically
after 15 minutes operation. On compressors without a condensate drain valve, condensate has to be drained
manually (see chapter 3).
Afterwards shut the system down.
- Open the couplings of the separators and lubricate them with Aluminum based Anti-sieze compound
10.3. PREVENTIVE MAINTENANCE DURING STORAGE
- Every 6 months turn the flywheel of the compressor several times.
10.4. REACTIVATING THE COMPRESSOR BLOCK
- Run the compressor warm with open filling valves or outlet valve for approx. 10 minutes.
- Check the intermediate-pressure safety valves for leakage.
- Establish cause of any fault from the trouble-shooting table, section 12, and remedy.
- Stop the system when running properly, the compressor is then ready for operation.
