Compressor's long period storage

In case the compressor is intended to stay out of operation for more than three months, special procedure should
be followed for the storage as well as for its re-operation:
 Make sure it is stored in a closed, dry, dust-free place.
 Run the compressor at normal pressure for 10-15 minutes.
 Check filters, hose connections and safety valves for leaks.
 Tighten all connections, if necessary.
 Open manual drain valves and run the compressor without pressure for 5 minutes.
 Stop the compressor, drain well and shut all valves.
 Open filters and put special grease used in the food industry or vaseline on all threads. Filter elements should
normally be in their place.
 Let the compressor cool down.
 Start the compressor and spray some compressor oil (5-6 c.c.) in the suction while in operation.
 Do not let the compressor heat up, stop its operation.
 Close all valves.
 Wrap the inlet air filter with nylon.
 Cover the compressor with a plastic cover to keep the dust out.
- Units and motors should always be stored in a dry, vibration - free and dust - free environment.
- Unprotected machined surfaces (shaft – ends and flanges) should be treated with an anti – corrosive.
- It is recommended that units and motors shafts are periodically rotated by hand to prevent grease
migration.
- Anti – condensation heaters are recommended to avoid water condensation in the motor and should
preferably be energized.

Re-Operation of the compressor after a long period of storage

 Remove the nylon and place a new inlet air filter.
 Follow the procedure related to the first start of the unit.
 Run the compressor functioning at normal pressure for 5-10 minutes.
 Change the oil.
 Place new coalescing filter cartridge, Active Carbon-Molecular Sieve cartridge.

Oil change

Change the oil after the first 20 operating hours and then every
500 hours. Always check the oil level through the oil sight
glass (3) before every start of the compressor. The level
should always be at the top of the sight glass. While the
compressor is operating the level should be between the
minimum and the maximum of the sight glass (red mark).
Oil change procedure: Unscrew the drain valve (1) with an
allen key nr. 5 and then empty the oil vessel. Screw the
drain valve again. Unscrew (may need allen key nr. 8) the
plug (2) and pour new oil (400ml for M6 models - 500ml
for M8 models) inside the compressor block till the upper
part of the oil sight glass. Screw the plug again and start
the compressor.

Intake air filter

Replace the intake air filter cartridge every 200 hours or once per year.
According to the environment it is recommended to change the
air filter element at the end of season.
