➤ 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.
➤ 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 vapors,
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 authorized 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 floating relay contacts.
➤ Close shut-off valves or otherwise isolate the machine from the compressed air network to en‐
sure that no compressed air can flow back into the machine.
➤ De-pressurize all pressurized 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.
➤ Carry out regular inspections:
for visible damages,
of safety installations,
of the EMERGENCY STOP push button,
of any components requiring monitoring.
