Instruction book Safety precautions Safety icons Explanation Danger to life Warning Important note General safety precautions 1. 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.
Instruction book can not supply any torque-generating energy. The drive is reliably torque-free. This state is monitored internally in the drive. The Safe Torque Off function does not disconnect the voltage of the main and auxiliary circuits from the drive. Maintenance work on electrical parts of the drive or the motor can only be carried out after isolating the drive system from the main supply! 10.

Instruction book 8. Ensure that the discharge pipe from the compressor to the aftercooler or air net is free to expand under heat and that it is not in contact with or close to flammable materials. 9. No external force may be exerted on the air outlet valve; the connected pipe must be free of strain.
Instruction book Safety precautions during operation 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.
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.

Instruction book Reference Description Cooling water circuit Position of components Air flow Air comes in through filter (AF) and inlet valve (IV) and is compressed in the compressor element (E). A mixture of compressed air and oil flows into the air receiver/oil separator (AR), where oil and air are separated.
Instruction book Cooling and condensate system Condensate drain system Condensate drains, Pack version Condensate drains, Full-Feature version Reference Designation Automatic condensate drain outlet Manual condensate drain outlet A condensate trap is installed downstream of the air cooler to prevent condensate from entering the air outlet pipe.
Instruction book Cooling system On air-cooled compressors, the air and oil coolers are cooled by frequency controlled fans. Compressor running parameters will define the cooling fan speed. Water-cooled compressors are provided with a cooling water system. Regulating system Description When the compressor is started and the net pressure is below the setpoint, the motor speed increases until the net pressure reaches the setpoint or until the maximum motor speed is reached.
The major part of the transformed heat is dissipated through the oil system. The Atlas Copco energy recovery systems are designed to recover most of the above- mentioned heat as warm or hot water without any adverse influence on the compressor performance.

Instruction book Integrated dryer Introduction Description The air dryer removes moisture from compressed air by cooling the air to near freezing point. This causes water to condense. The condensate is automatically drained. The air is warmed up before leaving the dryer (approx. 5 ˚C (9 ˚F) below the incoming air temperature). The air dryer cools down the compressed air to the preset temperature.
