5.1 The compressor has been designed and manufactured in accordance with the general safety requirements and standards relating to this type of device and in accordance with applicable technical regulations.
5.2 The main technical specifications for the compressor are provided in Appendix B.
5.3 For the technical specifications of the drive belt for the compressor, please refer to Appendix B.
5.4 For the technical specifications of the electric motors, please refer to Appendix B.
NOTE: THE BUILT-IN ELECTRIC MOTOR HAS AN EFFICIENCY RATING OF IE2 FOR INSTALLATION IN A COMPRESSOR.
5.5 For the technical specifications of the screw unit, please refer to Appendix B.
5.6 The compressor must be connected to a three phase power source (400V). The voltage and nominal values for the power supply and the current frequency are provided in Appendix B of this user manual.
5.7 The pressure within the air / pressure vessel is automatically controlled by the electronic control unit and the compressor control unit.
5.8 The compressors operate reliably at ambient temperatures from +5 °C to +40 °C, and at a maximum relative humidity of no more than 90%.
6 Commissioning
6.1 General information
Unpack the compressor carefully and check that the delivery is complete. Make sure that there are no visible signs of shipping damage.
- Remove the housing panels of the compressor.
- Perform a visual inspection for oil or other leaks.
- Check the oil level through the inspection window of the oil indicator.
It is recommended that the oil be refilled or replaced as described in Point 8.3.3 of this manual. Spare parts (oil filter, air filter, oil separator and a series of belts) required for technical maintenance must be obtained from the dealer or manufacturer.
6.2 Commissioning of the pressure vessel
The operation and manufacturing processes of the pressure vessel are governed by local laws.
The documents for the pressure vessel and the associated compressor must be safely stored throughout the life of the pressure vessel.
6.3 Installation
DO NOT OPERATE THE COMPRESSOR IN LOCATIONS WITH RISK OF EXPLOSION OR FIRE!
DO NOT OPERATE THE COMPRESSOR IN RAIN!
6.3.1 The overall dimensions of the compressor are stated in Appendix B.
6.3.2 In order that the compressor functions normally, the ambient temperature should not be lower than +5 °C, and no higher than +40 °C. Operation at a lower temperature leads to the penetration of condensate into the oil, thereby reducing its lubricating properties, which results in the reduced service life of the screw unit and increases the probability of failure.
The operation of the system at temperatures above the maximum value leads to a reduced efficiency coefficient in the heat exchanger and the oil cooling system.
An increased oil temperature triggers the activation of the thermal protection system, which stops / prevents the operation of the compressor. The operating temperature is displayed in the LED display of the control unit. The suctioned air must not contain dust nor explosive or flammable gases, solvents or colouring agents in aerosol form or toxic fumes.
6.3.3 Mounting of the rubber shock absorbers (compressors without boiler only)
Removable rubber shock absorbers must be mounted on the supports of the screw compressor housing.
DO NOT PERMANENTLY MOUNT THE COMPRESSOR TO THE FLOOR OR THE BASE PLATE!

6.3.4 Place the compressor on a horizontal flat surface in order to ensure better lubrication of the moving parts and the complete drainage of the condensate. Make sure that the compressor is installed on a flat, non-slip surface made of oil, fire and wear-resistant material.
6.3.5 Ensure easy access to control unit, suction filter and condensate drain regulator. To ensure proper ventilation and effective cooling, the compressor must be at least 50 cm from the wall.
6.4 Connection to an air system
6.4.1 When connecting the compressor to an air system or an execution unit, you must use pneumatic valves and flexible hoses with the correct dimensions and properties (diameter, pressure and temperature).
6.4.2 It is recommended that the outlet be equipped with a pressure reducing valve or similar fitting in order to ensure the reduction of the pressure of the discharged air from the pressure vessel.
6.5 Connection for secondary use of the emitted thermal energy
The heat emitted by the compressor cooler can be re-used. The discharged air contains heat and can be used at the compressor site or in another building area as air heating. If the latter is being considered, then the collection hood / duct component for transporting the expelled air must have a greater cross sectional area than the radiator. It is also necessary to further convey the air using a mechanical ventilator, to ensure a constant flow rate of air.
The collection hood / duct component directly above the radiator must be removable for inspection purposes.
6.6 Connection to the power supply
The permissible voltage fluctuations in the power supply should correspond to the data specified in the included manual.
Electrical cables must meet all safety standards and must have a cross-section that is in keeping with the power consumption of the compressor. All electrical connections must be realised by a qualified electrician. The compressor must be connected to the power supply by means of a fixed connection with appropriate insulation.
The compressor is equipped with an on/off switch for maintenance and repairs. The compressor must be properly earthed. Connect the protective conductor of the power cable to the PE connection (switch cabinet) in accordance with IEC 60204-1 requirements.
The earthing wire must have a solid core copper with a cross section as shown in Appendix B.
In accordance with IEC 60204-1, the power supply must have a circuit breaker.
The power supply to the compressor must be equipped with a circuit breaker (fuse) to protect the compressor against short circuits. This must be designed to comply with the emergency circuit breaker.
The compressors are suitable for use with a three phase power supply (400 V, 50 Hz), with a tolerance of 10% or 1%. The electric motor has a star-delta circuit. The voltage across the entire control and signalling circuit is 24 volts AC.
6.7 Schematic circuit diagrams for the compressors can be found in Appendix E.
7 Functions and operation
7.1 Functions
7.2 Functional principle
The air from the atmosphere passes through the air filter and the intake valve to the pair of screws, where it is mixed with oil and compressed. The air-oil mixture is transported under pressure to the oil sump, where the first coarse filtration / separation takes place. Due to its high self-weight, the oil runs down to the bottom of the oil sump housing.
Subsequently, the air-oil mixture enters the filter / separator, where the final filtration / separation of the oil and air mixture takes place.
The oil will be transported via the oil line / oil hose into the radiator where it cools and is filtered through the oil filter and again reaches the pair of screws, so that the cycle can start again. The oil has the task of cooling the air during the compression cycle, of lubricating the bearings and sealing the surface of the screw.
The air, which is cleaned of the oil residues by the filter / separator, is cooled as it flows through the air circuit of the cooler. Then, at a substantially lower temperature and with just minor water and oil residues, it reaches the outlet.
7.3 The functional diagram of the compressor unit can be found in Appendix C.
7.3 The general structure of the compressor can be found in Appendix C.
7.5 The control unit is constructed as shown in Figure 2: The operating instructions for the electronic control unit can be found in Point 7.8.

7.6 Compressor unit protection devices
The compressor is equipped with the following safety devices and control units that contribute to the protection and control of the main components and functions. These are as follows:
1 Safety valve, which is mounted to the compressed air tank (if present).
2 Safety valve, which is mounted to the oil collection tank.
3 Fuses FU 1-FU5 (5.5, 7.5, 22, 30 and 37 - KW) FU 1-FU8 (11 and 15 KW) (SeeAppendix E): for the protection of all control and signal circuits.
4 Circuit breakers, which provides protection against short circuits in the power supply.
5 Power monitoring, which provides protection against losses and asymmetric phases, as well as false phase sequences.
6 Temperature relay (on the wiring board) to protect the compressor motor against overload. The compressor is switched off when the temperature relay is switched.
7 Programmable controller, which monitors temperature and pressure and regulates the compressor automatically.
8 In the following cases, switching the compressor normally is not possible and the electric circuit is separated:
- Voltage recovery after power failure;
- Increase in oil temperature to above the permissible limit of +100 °C
- Use of the temperature relay;
- Indication of excess pressure.
DANGER: THE COMPRESSOR WAS STOPPED IN THE CASE OF AN EMERGENCY (ACTIVATION OF PROTECTION SYSTEM). FIND THE REASON FOR THE FAILURE BEFORE RESETTING THE COMPRESSOR AND CHECK THE THE FOLLOWING POINTS:
1 VOLTAGE, CHANGE IN THE THREE PHASES OF THE POWER SUPPLY. CHECK PHASE VOLTAGE AND CONNECTIONS.
2 IN THE CASE OF ACTIVATED MOTOR THERMAL PROTECTION:
- ALLOW THE THERMAL PROTECTION TO AUTOMATICALLY RESET.
- PRESS THE "RESET" BUTTON.
- SWITCH THE COMPRESSOR ON.
3 IN THE CASE OF ACTIVATED COMPRESSOR THERMAL PROTECTION, CHECK:
- IF OIL LEVEL AND SPECIFICATIONS ARE CORRECT.
- IF THE FAN / RADIATOR IS CLEAN.
- THE AMBIENT TEMPERATURE.
- THE FILTER LOAD.
- IF THE TEMPERATURE DROPS TO 97°C, PRESS THE "RESET" BUTTON AND SWITCH THE COMPRESSOR ON.
If all of the above mentioned measures have been completed and the compressor still does not work, or the deactivation error persists, then contact the company that carries out the annual maintenance of the compressor, or contact the seller or manufacturer.
A check regarding the direction of rotation of the drive shaft of the screw unit (indicated by an arrow on the screw unit housing) is performed by a technician during the installation and commissioning of the compressor. The voltage control relay shuts off the compressor to prevent it from being switched on in spite of the incorrect phase connection or an unacceptable operating voltage in the power supply.

7.8 Initial commissioning
Turn the main switch to position "I". The air pressure and screw temperature are displayed on the control unit. Press the START button to switch on the compressor. If the compressor does not start up upon pressing the START button, perform troubleshooting and follow the instructions in the appropriate section of the manual. When the compressor starts, fully open the bleed air valve fully and keep the compressor disconnected from any distribution systems. Then let the compressor run for several minutes without load to ensure the proper oil flow and lubrication of the worm screw.
DANGER: BEFORE INITIAL COMMISSIONING:
- FAMILIARISE YOURSELF WITH THE SYSTEMS AND COMPONENTS OF THE COMPRESSOR.
- VERIFY THAT THE SCREW TURNS IN THE DIRECTION INDICATED ON THE HOUSING AND THAT THE AIR FLOW IS DIRECTED UPWARD. IF THE SCREW ROTATES IN THE WRONG DIRECTION, THEN CHANGE THE PHASE CONNECTION OF THE POWER CORD.
- MAKE SURE THAT THE SYSTEM IS PROPERLY VENTILATED
- MAKE SURE THAT ALL COMPONENTS ARE PROPERLY SECURED.
7.9 Switching on the compressor
Start the compressor with an electric motor connected to the mains as follows:
1 If the connection is made via a local switch, switch it on.
2 Turn the main switch to position "I".
3 Press the START button to switch on the compressor
7.10 Switching off the compressor
To switch off the compressor when it is not in use, perform the following steps:
- Press the "STOP" button.
- Once the compressor stops, switch off the electric motor by turning the main switch to "0".
- The compressor cannot be restarted for 2 minutes following the manual switch off.
DANGER: ONLY USE THE "EMERGENCY OFF" SWITCH IN EXTREME CASES.
7.12 Monitoring and control processes in the operating sequence
When the predetermined maximum pressure is reached, the controller outputs a control signal to open the safety valve and the compressor will automatically switch to idle state. The intake valve then closes and the load is removed from the compressor.
When the pressure has been reduced to the predetermined minimum, the controller outputs a control signal to close the safety valve and open the intake valve. The compressor switches to operating mode and the pressure increases.
In automatic mode, the compressor switches off at regular intervals, if idle mode is activated during normal operation. This happens when the user switches off the air supply. This state is called "Standby" mode. "STANDBY" mode is only activated when the user switches off the air consumption or the compressor and this remains idle for more than 5 minutes. The compressor remains in this mode until the pressure falls below the lower limit of 2 bar. The compressor then automatically switches on again.
DANGER: BY PRESSING THE "STOP" BUTTON, THE COMPRESSOR SWITCHES TO "IDLE" MODE AND WILL THEN AUTOMATICALLY BE SWITCHED OFF AFTER A SPECIFIED TIME (DEPENDING ON MODEL, 30 TO 50 SECONDS).
To restart the compressor, press the "START" button.
8 Maintenance
8.1 During technical inspections, observe the instructions in this manual and the applicable health and safety rules and regulations.
DANGER: BEFORE PERFORMING ANY TYPE OF SERVICE, ENSURE THAT THE COMPRESSOR IS DISCONNECTED FROM THE POWER. THE AIR SYSTEM MUST BE SWITCHED OFF AND MUST NOT BE PRESSURISED
DANGER: SOME EQUIPMENT SURFACES CAN BECOME VERY HOT!
NOTE: PERFORM THE GENERAL CHECKS AFTER THE FIRST 50 OPERATING HOURS: CHECK THE OIL LEVEL, THE CONDITION OF THE RADIATOR, THE AIR FILTER, THE BELT TENSION AND THE GENERAL CONDITION OF THE ELECTRICAL CONNECTIONS AND ELECTRICAL EQUIPMENT.
NOTE: PERFORM THE FIRST OIL AND OIL FILTER CHANGE AFTER 500 HOURS (BREAKING-IN TIME) OR ONE YEAR AFTER DATE OF PURCHASE, DEPENDING ON WHICH OCCURS FIRST.

8.3.1 Checking the oil level
The oil level is visually (Figure 6) inspected. The maximum fill level is the lower edge of the oil filler neck and the lower limit is located at the centre of the viewing window (in the case of a cold compressor). If oil colour changes occur (whitening- contains water, darkening - extreme overheating), change the oil immediately (point 8.3.3).
8.3.2 Recommended types of oil
The nominal lubricating oil capacity for the compressor can be found in the "Spare parts for maintenance" table in Appendix F. It is recommended that your do not mix the different varieties and mineral compositions of the oil. We advise using the following oil brands and types for the compressor. However, similar or equivalent oil brands or types can be used. The screw compressor is shipped from the factory with mineral oil.
Manufacturer Type of oil
PREBENA Z.200.70 Mineralöl
PREBENA Z.200.80 Synthetiköl
WARNING: COMBINING DIFFERENT TYPES OF OIL AND OIL FROM DIFFERENT MANUFACTURERS IS STRICTLY FORBIDDEN AND VOIDS THE WARRANTY / GUARANTEE.
NOTE: SELECT A HIGH QUALITY OIL FOR SCREW COMPRESSORS, WITH A VISCOSITY OF 46 MM2/S AT 40°C, FLOW POINT FROM -8 to 10°C, WITH AN IGNITION TEMPERATURE OF MORE THAN 200 °C.
When replacing the compressor oil, it is important to completely remove the oil from oil reservoirs, screw conveyor unit, condenser and oil circulation lines. In addition, the oil filter and oil separator must be replaced.
8.3.3 Oil Change
When changing the oil, it is necessary:
1 To remove the right cover of the compressor housing.
2 To switch the compressor on, so that the oil can heat to over 71^ C (the radiator is simultaneously heated over the entire surface).
3 To switch off the compressor.
4 Within 5 minutes, unscrew the plug and slowly open the drain valve to remove the oil. Then all of the oil can be drained into a container and prepared for disposal.
5 To manually turn the screw 3-5 revolutions in the direction of the arrow on the front of the worm screw.
6 To remove the oil filter.
7 To install a new filter (before installing the filter, pour in a little oil so that the filter element is impregnated and then lubricate the gasket of the filter with oil). To do so, use the same oil as for filling the compressor.
8 To dismantle the filter / oil separator.
To install a new filter / oil separator, having previously greased the gasket of the filter with oil. To do so, use the same oil as for filling the compressor.
9 To close the drain valve and fill the new oil through the filler neck to the upper edge of the inspection hole of the oil indicator. Then screw the plug back into the filler neck.
10 To switch on the compressor and then switch it off again after reaching the oil temperature of more than 71^ C. After the oil-foam subsides, you can then check the oil level through the inspection window and top up if necessary.
11 To replace the right panel of the compressor housing.
NOTE: IN THE CASE OF AN ELEVATED DUST CONTENT IN THE AIR, MORE FREQUENT MAINTENANCE MUST BE PERFORMED. SPECIAL CONSIDERATION MUST BE GIVEN TO HE RADIATOR IN THIS REGARD. IT MUST BE CLEANED/REPLACED MORE OFTEN, ALONG WITH THE AIR FILTER.
8.3.4 Cap for draining oil
The cap for draining the oil is located at the bottom of the oil sump and serves the purpose of draining the oil during maintenance and oil change.
When draining the oil, the condensate must also be removed via the cap (if required).
All tasks / activities in which the cap has to be removed should be performed when there is no pressure in the oil sump and when the compressor is off.
8.3.5 Oil filler neck
The oil filler neck is located directly on the oil tank and is locked with a special screw (Figure 5). This lock can only be opened when the pressure in the compressor corresponds to the normal air pressure. Danger: The cap should not be removed when the compressor is running or is pressurised.

MAX MINFigure 6
8.3.6 Replacement of the belt
When replacing the belt, the following is required:
a) Remove the right cover of the compressor housing and the protective device.
b) Loosen the four screws of the motor platform.
c) Reduce the belt tension by moving the motor platform in the direction of screw conveyor unit
d) Remove the belt.
e) Clean the grooves of the pulley with a cleaning cloth and install the new belt.
f) Now increase the tension by moving the electric motor platform away from the worm screw. Ensure that the belt tension and deflection are adjusted as shown in Figure 7.
g) Tighten the motor platform by tightening the screws firmly.
h) Place the protection device and the cover back on the compressor housing.
8.3.7 Checking the belt tension
The belt tension adjustment is performed in accordance with Point 8.3.6.
The power of the electric motor is transmitted by means of the contact of the belt with the pulleys. To ensure normal operation, all contact surfaces must be clean and the belt must be fully taught and set to the correct tension / deflection.
The belt tension should be checked after assembly and periodically during operation, especially if the compressor has not been used over a period of at least one week.
The belt deflection should be adapted and adjusted using a dynamometer, a string and a ruler (Figure 7).
The power is transmitted via the belt, whereby frictional forces are generated between the belt and pulleys, transferred from the electric motor to the drive of the screw assembly. To ensure normal operation, all surfaces of belts and pulleys must be kept clean and tightened to the correct pressure.
The belt tension must be checked after assembly and periodically during operation, especially if the compressor has not been used over a period of at least one week.
3 to 5 operating hours after the belt change, check the tension, since the belt has been subject to intensive expansion during this period, which may lead to a friction-induced slippage and thus to power loss and damage.
For compressors up to 15 kW: The belt must be tightened and may only yield up to a maximum of 5-6 mm at an applied force (F) of 30 N (Figure 7).
For compressors from 22 KW: The belt must be tightened and may only yield up to a maximum of 4-5 mm at an applied force (F) of 35 N (Figure 7).

4.5 mm F = 35 N> = 22KW
Figure 7
8.3.8 Checking the intake filter (filter element)
The compressor requires a large volume of air for operation and internal ventilation / cooling. Therefore, an excessive amount of dust in the air leads to a malfunction in the normal operation of the compressor. A certain amount of dust remains in the air intake, meaning that it clogs quickly. The dust settles quickly on various internal modules and components, including the air / oil cooler, and hinders the heat exchange / cooling process. For this reason, it is important to check the air intake before operation and to clean the work area regularly. This is the only way that the normal operation of the system can be ensured and unexpectedly high maintenance costs avoided.
DANGER: IF THE AIR IS MIXED WITH ORGANIC AND MINERAL DUST OR CORROSIVE CHEMICAL VAPOUR, THE COMPRESSOR MUST BE IMMEDIATELY SUPPLIED WITH CLEAN / FILTERED AIR.
8.3.9 Replacement of suction filter (filter element)
This must be performed every 500 hours or at least three times per year. Proceed as follows:
- Open the cover to access the air filter.
- Loosen the wing nut and hold the cover of the housing secure.
- Remove the air filter element and install a new one.
- Replace the cover and tighten the wing nut.
8.3.10 Oil filter change
This must be performed every 4000 hours or at least once per year. Proceed as follows:
- Open the front door of the compressor.
- Turn the oil filter anti-clockwise to remove it.
- Carefully clean the seat of the oil filter housing.
- Pour some oil into the new filter until the filter element is saturated.
- Apply some oil to the new filter gasket.
- Turn the oil filter clockwise by hand. To do this, do not use any tools, because you may damage the housing of the oil filter.
8.3.11 Replacement of the oil separator
This must be performed every 4000 hours or at least once per year. Proceed as follows:
- Open the front door of the compressor.
- Turn the separator anti-clockwise to remove it.
- Carefully clean the seat of the separator housing.
- Apply some oil to the new separator gasket.
- Tighten the trap clockwise by hand, do no use any tools as you may damage the housing of the separator.
- Check the oil separation after 2 to 3 hours (display).
8.3.12 Condensate drainage
Drain the condensate daily and after each use.
1 Switch off the compressor in accordance with Point 7.11.
2 Decompress the pressure vessel to 2-3 bar.
3 Place a container beneath the condensate drainage point.
4 Open the ball valve and drain the condensate.
5 Close the ball valve.
6 Dispose of the drained condensate in accordance with environmental protection regulations.
DANGER: NEVER DRAIN CONDENSATE OR OIL FROM THE PRESSURE VESSEL WHEN PRESSURISED. BEFORE PERFORMING ANY MAINTENANCE, RELEASE PRESSURE AND SWITCH OFF THE SYSTEM.
8.3.13 Checking the connection tightness of the air line
Check the connection tightness of the air line daily and before each use. To check the connection tightness, the compressor should be switched on and the pressure in the pressure vessel should be a maximum of 5-7 bar. There must be no audible air leaks at the connection points. If necessary, tighten the connection points.
DANGER: BEFORE TIGHTENING THE CONNECTION POINTS, THE COMPRESSOR MUST BE DEPRESSURISED!
8.3.14 External inspection of the compressor
Check the electric cable, the safety valve, the pressure gauge, the pressure vessel and the pressure switch for damage that could compromise the correct operation daily and before each use. Ensure that there are no deformities or fractures and that the earth wire is connected properly.
8.3.15 Checking the safety valve on the compressed air container (applies only to models with a compressed air tank)
The safety valve is a valve spring (Figure 8). It has been adjusted in the factory, set to the correct opening pressure and sealed. Breaking the seal and changing the setting is prohibited and is not possible without destroying the integrity of the valve body. Interventions to the safety valve void the manufacturer's warranty.
A test of the safety valve can be performed during normal compressor operation. The safety valve can be tested as soon as the pressure in the compressed air container is ≥ 85% of the opening pressure.
The valve can be inspected manually via the pull ring on the upper part of the safety valve. The test proceeds as follows: Pull the ring up when the upper pressure level has been reached in the pressure vessel. Continue pulling until the valve is half open and discharges pressure, then let the ring go so that it can return to the home position again. If the valve can no longer seal the valve seat, it is broken and must be replaced.

NOTE: IF THE PRESSURE VESSELS IS DELIVERED WITH A SAFETY VALVE WITHOUT A MANUAL TEST RING, THEN TEST BY REMOVING THE SAFETY VALVE (ENSURE THE PRESSURE IN THE PRESSURE VESSEL CORRESPONDS TO THE NORMAL AIR PRESSURE AND THAT THE COMPRESSOR IS SWITCHED OFF). THE FUNCTIONALITY IS THEN TESTED ON A TEST STAND, AT LEAST ANNUALLY.
8.4 Install the protection equipment and other components after maintenance is complete. Observe the instructions regarding initial start-up (Point 7.9).
8.5 Ensure that all maintenance work is carried out and recorded in the maintenance log (Appendix F). This is a useful form with which to quickly check maintenance work, which must be kept filled out for documentation purposes.
