Conservation / storage of the compressor
If the compressor unit is not to be used for an extended period of time, we recommend to
carry out the following work before storage time:
•
Run the compressor at 200 bar filling pressure for approximately ten minutes
(control the flow with the filling valve to maintain constant pressure).
•
Replace compressor oil, open filling valve(s) and run compressor for a few minutes.
•
Stop compressor and open drain valves (depending on the compressor type, this may
happens automatically).
Remove top cap of final filter housing: clean threat, grease o-ring.
and threat with a food grade grease or silicone grease. Close filter housing.
•
Remove intake filter cartridge and undo intake pipes on all valve heads.
•
Start compressor unit. Spray a few drops of compressor oil into intake connectors.
•
Stop compressor unit and insert intake filter cartridge. Bring intake pipes back in position and
fix connections and nuts.
Close filling- and drain valves.
•
Store the compressor in a cool dry place free from dust and contamination.
A dust cover is recommended as long as condensation can be avoided.
•
If compressor unit should be stored for a period of more than one year, an oil change is
strongly recommended before it’s been re-used.
•
Fuel driven units only: fill up fuel tank to top level to avoid corrosion.
De-conservation, commissioning
After the compressor has been stored, the following steps are to be taken:
•
If compressor hasn’t been used for longer than 12 months, we strongly recommend an oil
change before any use.
•
Replace intake filter cartridge and check oil level.
•
Clean compressor unit, check for foreign objects.
Check condition and tension of V-belts,
replace if necessary. Check condition of filling hoses, replace if necessary.
•
Secure hoses against whipping and open filling valves and run compressor for approximately
10 minutes.
•
Check condition of final filter cartridge, replace if necessary.
•
Close filling valves and run compressor up to final pressure.
•
Check safety valve relief pressure of final stage and/or pressure switch setting.
•
Check all connections and pipe work for leaks.
Once all above steps are completed, compressor unit is now ready for use.
