General recommendations
Comply with Accident Prevention Regulations VBG 16 “Compressors”,
in particular Section IIIc “Installation” and IV “Operation” and VBG 4
“Electrical Equipment and Devices”.
Due to high temperatures occurring during gas compression, protect
area around installation by suitable means, eliminating injury hazards
to persons in the vicinity by hot surfaces.
• When operating this compressor, ensure that only normal atmospheric
intake air is available. It is not suitable for toxic or inflammable media.
When handling dusty materials, ensure that any created dust/air
mixtures does not reach ignition temperatures. Install an additional
temperature gauge.
• Piping should be clean and properly dimensioned.
• It is recommended to install the compressor for easy maintenance
accessibility.
• Select adequate clearances from adjacent walls to ensure sufficient
air flow for cooling.
• Maximum ambient temperature: 45°C.
• Minimum ambient temperature: 5°C.
• Maximum 4-6 on/off cycles per hour.
• To eliminate reversing of the pump for pipework exceeding a length
of 2 m, install non-return valves.
Commissioning
Fill with BECKER LUBE S320 oil to edge of filler cap OE (approx. 4.7 l).
• Remove caps from point DA. Do not connect to piping.
• Have motor connected based on wiring diagram (in terminal box)
by an authorised electrician: for connection ensure correct voltage
and current.
• Include motor overload protection if required.
• Briefly start motor to check rotation (arrow on motor flange). Reverse
phases if rotation is incorrect.
The thread for the pressure connection is suitable for maximum pipe
lengths of 3 m. Use next larger diameter for pipe lengths of up to 10
m. Contact the factory to ensure optimum pipe diameters for longer
distances.
Connection
• Connect pressure pipe at point DA.
• Do not operate compressor without overpressure protection (for
maximum pressures see name plate). Fit a pressure gauge and mark
the final pressure on it if the pressure can 1 bar.
• After a long time of not using run the pump for half an hour without
load.
• Prevent blockage of oil separators by installation of a thermostat
(optional).
Maintenance
Regular maintenance of the pump will ensure best results. Maintenance
intervals are dependent on local conditions. Therefore initially shorter
maintenance intervals should be set and adjusted later, based on
experience gained.
• Before commencing maintenance, disconnect pump to prevent
unintentional restarts.
• Clean pump surface, the compressed air cooler system KD and
cooling air ducts KL by compressed air to ensure sufficient air cooling.
Oil/oil separator
Check the oil level daily. Refill oil if oil level indicator is on centre of sight
glass OS. First oil change after 100 and subsequent oil changes every
500 to 1000 operating hours. Drain used oil through drain plug OA.
• Replace oil separator FA every 1000 to 2000 operating hours. Release
the seven bolts on the cover GO. Check coarse oil separator GA
and clean if dirty.
Filter
• The filter cartridge FP is fitted behind the cover of the housing GD.
Should the ambient air be very dusty and under specific operating
conditions (operation in more than one shift per day), weekly filter
checks are recommended (initially twice per week).
• Clean dirty filters by compressed air from inside to outside.
• Blocked, oily or greasy cartridges must be exchanged.
Vanes
Vanes are wearing parts.
• Check width of vanes every 2000 operating hours (for minimum
width see Table).
• Release cover AB (four bolts) and two oil pipes OL. Remove oil tank
OB and release oil pipe L3. Then remove side cover SD.
• Make sure that the vanes are fitted with the running edges in the
correct position.
Bearings
• Check shaft seals for leakages and bearings for wear.
