  • Page 10 Instruction book • No external force may be exerted on the air outlet valve; the connected pipe must be free of strain. • If remote control is installed, the machine must bear a clear sign stating: DANGER: This machine is remotely controlled and may start without warning. The operator has to make sure that the machine is stopped and depressurized and that the electrical isolating switch is open, locked and labelled with a temporary warning before any maintenance or repair.
  • Page 11 Instruction book • Never touch any piping or components of the machine during operation. • Use only the correct type and size of hose end fittings and connections. When blowing through a hose or air line, ensure that the open end is held securely. A free end will whip and may cause injury.
  • Page 12 Instruction book Safety precautions during maintenance or repair WARNING 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 13 Instruction book • 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 14 Instruction book Disposal • Always adhere to local regulations when disposing of the equipment. These regulations may require specific procedures or designated facilities for handling electrical waste (e-waste) and specific materials or components. • Many parts are recyclable including metals like steel, aluminium, copper and precious metals. Plastics, rubber, cardboard and other packaging material can be used in energy recovery.

  • Page 21 Instruction book Regulating system Figure 8: Regulating system (loaded condition) Loading When the net pressure is below the loading pressure, solenoid valve (Y1) is energized. Results: • The space above the unloading valve/blow-off valve (UV) is connected with the oil separator tank pressure (1) via the solenoid valve.
  • Page 22 Instruction book VSD regulating system If the consumption is less than the air output of the compressor, the net pressure increases. When the net pressure is higher than the setpoint (desired net pressure), the controller will decrease the motor speed. If the net pressure keeps on rising when the motor runs at minimum speed, the unit will run unloaded for 5 min, before the controller stops the motor.
