Operating Instructions
Rotary Vane Compressor
oillubricated, aircooled
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: 40-45 °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 Anderol 1200 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 exceed +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. Main-
tenance 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.
