➤ Never dismantle pressure lines 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.
Installation
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.
➤ Clean inlet gas with no 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.
Commissioning, operation and maintenance
During commissioning, operation and maintenance you may be exposed to dangers resulting from,
e.g., electricity, pressure and temperature. Careless actions can cause accidents with severe ad‐
verse effects for your health.
➤ Allow maintenance work to be carried out only by authorised personnel.
➤ Wear close-fitting, flame-resistant clothing. Wear protective clothing as necessary.
➤ Switch off and lock out the power supply isolating device and verify the absence of voltage.
➤ Check that there is no voltage on potential-free contacts.
➤ Close shut-off valves or otherwise isolate the machine from the gas network to ensure that no
compressed gas can flow back into the machine.
➤ De-pressurise all pressurised components and enclosures.
➤ Allow the machine to cool down.
➤ Do not open the cabinet while the machine is switched on.
➤ Do not open or dismantle any valves.
➤ Use only spare parts approved by KAESER for use in this machine.
