A.3 Long Term Storage
A.3.1
General
If the compressor unit will be out of service for more than six months, it should be preserved in accor-
dance with the following instructions:
1. Make sure that the compressor is kept indoors in a dry, dust-free room.
2. Cover the compressor with plastic sheets only if no condensation will form under the sheet.
3. Remove the sheet from time to time and clean the outside of the unit.
4. If this procedure cannot be followed, or if the compressor will be out of service for more than 24
months, please contact the BAUER Service Department for special instructions.
A.3.2
Preparations
Prior to preserving the compressor unit, it must be run until warm, i.e., up to the specified service pres-
sure. Operate the unit for approximately 10 minutes, then carry out the following checks.
1. Check all pipes, filters and valves (including safety valves) for leakage.
2. Tighten all couplings, as required.
3. After 10 minutes, open the outlet valve and operate the compressor at adjusted minimum pressure
using the pressure maintaining valve for approximately 5 minutes.
4. After the 5 minutes, shut the compressor unit down and completely drain all separators and filters.
Close all valves.
5. Remove filter heads and lubricate the threads with petroleum jelly.
A.3.2.1 Units Equipped with a Filter System
1. Ensure that cartridges remain in the purification system chambers. This will prevent oil from entering
the outlet lines as a result of preservation procedures.
2. Remove the intake filter/intake pipe completely.
A.3.3
Preserving the Compressor
1. Operate the compressor again and slowly spray approximately 0.35 oz. (10 cc) of oil into the inlet
port while the compressor is running. Keep the shut-off valve open and the condensate drain valves
closed.
2. After spraying the oil into the inlet port, run the compressor unit for an additional 5 minutes before
shutting the compressor unit down.
3. Close the shut-off valve.
4. Close the inlet port with a dust cap and/or tape.
A.3.4
Preventive Maintenance During Storage
Operate the compressor once every six months as follows:
1. Remove the dust cap from the inlet port and install the inlet filter.
2. Open the outlet valve and allow the system to run approximately 5 minutes until there is outflow from
the valve and oil is visible in the sight glass of the oil regulating valve.
