Transporting
The weight and size of the machine require safety measures during its transport to prevent acci‐
dents.
➤ Use suitable lifting gear that conforms to local safety regulations.
➤ Allow transportation only by personnel trained in the safe movement of loads.
➤ Attach lifting gear only to suitable lifting points.
➤ Be aware of the centre of gravity to avoid tipping.
➤ Make sure the danger zone is clear of personnel.
➤ Do not step onto machine components to climb up the machine.
Assembly
➤ Only use only electrical cables that are suitable and approved for the surroundings and electri‐
cal loads applied.
➤ Never dismantle compressed air pipes until they are fully vented.
➤ Only use pressure lines that are suitable and approved for the maximum working pressure and
the intended medium.
➤ Do not allow connection pipes to be placed under mechanical stress.
➤ Do not induce any forces into the machine via the connections, so that the compressive forces
must be balanced by bracing.
Positioning
A suitable installation location for the machine prevents accidents and faults.
➤ Install the machine in a suitable compressor room.
➤ Ensure sufficient and suitable lighting such that the display can be read and work carried out
comfortably and safely.
➤ Ensure accessibility so that all work on the machine can be carried out without danger or hin‐
drance.
➤ If installed outdoors, the machine must be protected from frost, direct sunlight, dust, rain and
splashing water.
➤ Do not operate in areas in which specific requirements regarding explosion protection are in
force.
For instance, the requirements of ATEX directive 94/9/EC "Equipment and Protective Systems
intended for use in Potentially Explosive Atmospheres".
➤ Ensure adequate ventilation.
➤ Place the machine in such a manner that the working conditions in its environment are not im‐
paired.
➤ Comply with limit values for ambient temperature and humidity.
➤ The intake air must not contain any damaging contaminants,
Damaging contaminants are for instance: explosive or chemically instable gases and vapours,
acid or base forming substances such as ammonia, chlorine or hydrogen sulfide.
➤ Do not position the machine in warm cooling outlet air from other machines.
➤ Keep suitable fire extinguishing agents ready for use.
