The operator must employ safe working practices and observe all related work safety requirements and regulations. 2. If any of the following statements does not comply with the applicable legislation, the stricter of the two shall apply. -
Page 8: Safety Precautions During Installation
Instruction book Safety precautions during installation All responsibility for any damage or injury resulting from neglecting these precautions, or non observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer. -
Page 9: Safety Precautions During Operation
Instruction book 18. If the ground is not level or can be subject to variable inclination, consult the manufacturer. Also consult following safety precautions: Safety precautions during operation Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. -
Page 10: Safety Precautions During Maintenance Or Repair
Instruction book Also consult following safety precautions: Safety precautions during installation Safety precautions during maintenance. These precautions apply to machinery processing or consuming air or inert gas. Processing of any other gas requires additional safety precautions typical to the application which are not included herein. - Page 11 Instruction book 18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering them, e.g. when steam cleaning. 19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork and in the air inlet and outlet systems of the compressor, is in good condition. If damaged, replace it by genuine material from the manufacturer to prevent the sound pressure level from increasing.

Page 12: General Description
General description Introduction GA 5 VSD MED up to GA 15 VSD MED are single-stage, oil-injected screw compressors driven by an electric motor. The compressors are air-cooled. The motor is powered by a frequency converter, allowing to adapt the speed to the air demand for optimal power consumption. -
Page 13: Air Flow
Instruction book Reference Name Function Elektronikon® controller See sections Elektronikon Graphic controller - General and further. Emergency stop button To stop the unit in case of emergency Mains switch To switch off the power to the compressor. Ammeter Indicates the compressor current. Hand / Auto (Local / LAN) switch In the Auto (LAN) position, the pump will be controlled by the ES MED. -
Page 14: Oil Flow
Instruction book Description Air drawn through filter (AF) and open inlet valve (IV) into compressor element (E) is compressed. Compressed air and oil flow into the oil tank (OT). The air is discharged through outlet valve (AV) via minimum pressure valve (Vp) and air cooler (Ca). During loaded operation, minimum pressure valve (Vp) keeps the pressure in the separator tank (OT) above a minimum value, required for lubrication. -
Page 15: Cooling System
Instruction book serves as oil tank. The remaining oil is removed by oil separator (OS). A small pipe returns the separated oil towards the compressor element. Air pressure forces the oil from oil separator/tank through oil cooler (Co) and oil filter (OF) towards compressor element (E). -
Page 16: Condensate System
Instruction book Condensate system Condensate drains Condensate drain connections The compressors have a condensate trap (MT) downstream the air cooler. The condensate trap is provided with a manual drain outlet (Dm) and an automatic drain outlet (Da). Regulating system Unloading valve assembly (loaded condition) Description If the consumption is less than the air output of the compressor, the net pressure increases. -
Page 17: Electrical System
Instruction book • Unloading valve (UV) is opened by the pressure in the oil separator vessel. The pressure from the oil separator vessel is released into atmosphere through the unloader (UA). • The pressure in the oil separator vessel stabilises at low value. A reduced amount of air is compressed to guarantee a minimal pressure, required for lubrication during unloaded operation. -

It is a normally open switch, and it closes when the pressure is above 2-3 bar.

Page 20: Air Receiver
Instruction book This sensor measures the temperature of the compressed air after the cooler. It gives a warning when the temperature exceeds 55°C, since this is not optimal for the dryer down the line. Ammeter The Ammeter in the cubicle door measures the current and allows to follow up unusual behaviour. Main switch The main switch allows to cut the power supply to the cubicle, during maintenance or during problem solving. -
