Safety and Responsibility

Extension or modification of the compressed air station
If a compressed air installation is to be extended or modified, check the blow---off ca-
pacity of the pressure relief valves on air receivers and pipelines before installing the
new machines.
Pressure relief valves of insufficient blowoff capacity must be replaced by valves with a
higher capacity.
3.5.2 Safe machine operation
Here is found information to support safe conduct with the machine.
Transport
Use suitable lifting gear that conforms to local safety regulations.
Attach lifting gear only to the designated points on the machine.
Make sure the centre of gravity is correctly positioned to avoid the machine tipping.
Make sure the danger zone is clear.
Installation
Make sure no power is applied when electrical connections are made.
Only use only electrical cables that are suitable and approved for the the loads ap-
plied.
Install or remove pressure lines only when they are in the depressurised condition.
Only use pressure lines that are suitable and approved for the maximum working pres-
sure and medium used.
Do not allow connecting pipes to be under mechanical stress.
Do not step onto machine components to climb up the machine.
Location
Install the machine in a suitable room.
If installed outdoors, the machine must be protected from frost, direct sunlight, dust
and rain.
The machine is not explosion---proof.
Do not operate in areas in which specific requirements with regard to explosion
protection are applied.
For instance, the requirements of the ATEX directive 94/9/EC ”Equipment and Protec-
tive Systems for use in Explosive Atmospheres”.
Ensure adequate ventilation.
Observe the required ambient conditions:
ambient temperature and humidity,
clean inlet air with no damaging contaminants,
inlet air free of explosive or chemically unstable gases or vapours,
inlet air free of acid---forming substances, particularly ammonia, chlorine or hydro-
sulphide.
Do not position the machine in the warm exhaust air from other machines.
Ensure accessibility so that all work on the machine can be carried out without danger
or hindrance.
Operation
Keep the machine enclosure closed for safety and correct cooling function.
