Page 9: Contents
Suitability/General information The German version of these instructions is the “Original instructions”. Any version in a language other than German is a “Translation of the original instruc- tions”. Aerzener rotary piston machines are suitable for the oil-free conveying and compression of air and, if specially modified versions are used, various other types of gas. -
Page 10: Construction, Function
Construction, function Jet starter: Jet starter are supplied as machines to be installed. Completed with adequate accessory the screw compressor is ready for use. The screw compressors are suitable for steady operation as well as for installation in mobile compressor units. Operation in mobile units may be effected only when the running gear is in idle position. - Page 11 Function: Aerzener screw compressors are rotary piston machines whose rotors turn uniformly against each other. Timing gear wheels guarantee contact-free running of the rotors. A drive shaft including the gear ratio ensures that the rotors run at the required speed. During operation, the material to be conveyed flows through the intake flange to the housing and inlet for the rotors.

Page 12: Precautions Prior To And During Operation
Due Care to Be Taken Before and During Operation CAUTION! Identifies all hazardous situations WARNING! Indicates direct risk to personnel Upon arrival/receipt, the rotary piston machine must be checked against the delivery and order documentation to make sure it has not been damaged during transit and is complete. - Page 13 Any operation that impairs machine safety is prohibited. The supplier documentation provided with the accessories and the general safety regulations must also be observed. The unit contains rotating components. If their protective equipment, according to the version of the unit, e.g. the acoustic hood, belt guard, coupling guard etc., are not observed or are not used appropriately, there is a Risk of injury! Protective equipment such as the belt guard/coupling guard, blower guard, hood...
- Page 14 unit must have read and understood the operating instructions. The unit must only be operated by trained and authorised personnel. Personnel must be trained according to the operating instructions. Responsibility for operation must be precisely defined in order to prevent any unclear designation of responsibilities.
- Page 15 before disassembly. Note the oil temperature when changing the oil. The oil temperature must rise above 60°C. If it is above 60°C, there is a risk of burns! Personal protective measures Conveying ducts or components on the discharge side must not be touched without adequate protection.
- Page 16 of glowing embers! Depending on the size and increased fire protection regulations, a flame retardant foam would be applied according to the order. Information about the event of damage If the unit produces an abnormal and/or unusual sound, the machine must be shut down immediately using the EMERGENCY BREAK function.

Page 17: Inadmissible Operating Methods
Inadmissible operating methods • Installation on uneven and / slanting foundations. • Securing transport devices to the acoustic hood, e.g. using eye bolts in the accou- stic hood element, winding ropes without expansion braces etc. • Non-observance of operating data. •... -
Page 18: Transport/Installation
Transport / Installation When transporting the machine, the following key points must be observed: • Do not expose the compressor to impact loads. • Transport the compressor using a crane, fork-lift truck, lift trolley or similar. • Use suitable hoisting gear that is appropriate for the load concerned. Failure to observe this point could result in damage or injury! •... - Page 19 During installation the following points must be observed: • Prior to delivery, rotary piston machines are treated and packaged to allow for a 12-month storage period. If they are to remain in storage following this 12-month period, they will need to be retreated; see storage and mothballing guidelines TN0 1175.

Page 21: Commissioning
Commissioning Install and assemble the compressor stage in accordance with these instructions. Assemble the driving elements correctly. CAUTION! Do not establish any connection with the driving motor yet. On first commissioning: Fill up lubricating oil on empty machines. Check lubricating oil level and correct if necessary. Check that the oil filling plug and the drain valve are seated securely and do not leak. -
Page 22: Shutting Down/Taking Out Of Operation
Switch off / shutdown • Switch off is carried out using the motor power switch. • If the drive motor is shut down in an operating position with back pressure, the pressure decelerates the compressor and brings it to a standstill more quickly. The non-return valve installed at the discharge side closes, which prevents the com- pressor from decompressing the compressed material and running in reverse. -
Page 23: Maintenance
Maintenance Maintenance is to ensure that all functions are maintained or that they can be restored after a breakdown. Maintenance includes specifications about inspection, service and repairs. Maintenance includes instructions for trained and qualified personnel. If anything is unclear consult Aerzener customer service. During inquiries please state: •... -
Page 24: Inspection/Inspection Schedule
Inspections / inspection schedule A general inspection should be carried out by a service technician from Aerzener after 3 years or 20,000 operating hours. This includes the preventive maintenance of wearing and replacement parts such as bea- rings, seal, etc. We recommend maintaining a stock of replacement and wearing parts to avoid or reduce waiting times and downtimes. -
Page 25: Maintenance Schedule
Maintenance schedule Whenever work is carried out on the rotary piston machine, it must be switched off and isolated from the electrical mains supply. Failure to observe this point could result in injury or damage. To ensure a long service life and optimum operating conditions, various steps should be taken. These include observ- ance of the maintenance operations and intervals specified in this table. -
Page 26: Lubricating Oil Specification
