E. STORAGE, PRESERVATION
1. GENERAL
If the compressor is 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. Neverthe
less, 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.
2. PREPARATION
Before preserving the compressor unit, run it warm and
when it reaches the specified service pressure, keep it run
ning 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.
- After 10 minutes, open the filling valves or the outlet
valve and run the compressor at the set minimum pres
sure (pressure maintaining valve, see chapter 6) for ap
prox. 5 minutes.
- After these 5 minutes, shut the system down. Drain con
densate from separators. Depressurize unit. Shut filling
valves/outlet valve.
- Open filters and grease threads.
On units equipped with a filter system please observe the
following:
- Ensure that filter cartridges remain in filters!
This will prevent oil entering filling lines as a result of
preservation procedures.
- Remove intake filter from manifold and all intake lines
from valve heads.
- Let compressor unit cool down.
3. PRESERVING THE COMPRESSOR
- Turn the compressor on and spray a small amount (ap
prox. 10 cm
3
of compressor oil into the valve head inlet
port while the compressor is running. Do not let the
compressor warm up too much, to keep oil sticky.
- Shut compressor unit off.
- Close all valves.
- Place the dust cap onto the inlet port.
4. PRESERVING THE MOTOR/ENGINE
Preserve the motor/engine according to the instructions of
the motor/engine manufacturer.
5. PREVENTIVE MAINTENANCE DURING
STORAGE
Run the compressor once every 6 months as described in
the following:
- Remove the dust cap from the inlet port and insert the
intake filter.
- Open the filling valves or the outlet valve and let the unit
run for approx. 10 minutes or until the pressure gauges
indicate the correct values.
- Stop the compressor.
- Open condensate drain valves and release compressed
air. Close condensate drain valves again.
- Carry out preservation procedure according to para.3.
5.1. CHANGING THE LUBE OIL FOR PRESERV
ING
- After prolonged storage, the oil will age in the compres
sor and engine. It should be drained after 2 years at the
latest and replaced with fresh oil.
- The stated period can only be attained when the crank
case is sealed during the preservation period in accor
dance with the preservation requirements.
- After changing the oil, turn the compressor and the en
gine or run them for the required period. See paras. 3.
and 4.
- Check the lubrication of the compressor when putting
the unit into operation once every six months or when
turning the compressor.
The oil pump is functioning properly when oil can be seen
flowing through the sight glass of the oil pressure regulator
and if the oil pressure gauge indicates the prescribed pres
sure.
6. REACTIVATING THE COMPRESSOR
UNIT
- Remove the dust cap from the inlet port and insert the
intake filter.
- Check the oil level of the compressor.
- Check the motor/engine according to the manufactur
er's instructions.
- Only applicable for units equipped with a filter system:
open the purifier and change all filter cartridges.
- Run the compressor warm with open filling valves or
outlet valve for approx. 10 minutes.
