Particular Dangers Associated With Machines; Particular Dangers Associated With Water-Cooled Units - Gardner Denver L55 User And Service Manual

4.3 Particular dangers associated with machines

Danger
Risk of electric shock.
Insufficient power quality could have
a strong effect on health & safety and
may constitute a risk to life and limb
of the user or third parties.
Remote-controlled units may start up
unexpectedly.
Noise, even when it is not very loud,
can make us nervous and irritated,
and after a longer period of time our
nervous system can suffer serious
damage.

4.4 Particular dangers associated with water-cooled units

Danger
If open cooling towers are used in the
cooling water circuit, it is possible for
legionella (Legionella pneumophila)
and other bacteria to grow and
spread.
As a result of leakage in oil/water
coolers, some oil may get into the
cooling water circuit.

Safety measure required
Electrical connections must meet the local regulations. Power units must be
connected to earth and protected from short-circuits by means of fuses.
Always check a correct power supply to the compressor before commissioning.
The voltage supply has to fulfill the requirements of EN60204-1/IEC60204-1 for
such kind of industrial equipment.
If a remote control is used, the system must carry a clearly visible sign with the
following note: Attention! This installation is operated by remote control and can
start up without prior warning!
As an additional safety measure, persons who start remotely controlled systems
have to take sufficient safety precautions in order to ensure that nobody is
checking the system or working on it. For this, a label with a corresponding
warning notice has to be attached to the remote control equipment.
We recommend a separate machine room in order to keep the noise of the
machine away from the workshop.
Where necessary, wear the personal hearing protection.
In order to consider all noise-relevant parameters and to adequately protect the
health of the operator, the European Regulation 2003/10/EC must be satisfied
completely by the user. In states outside the European Union, the respective
noise protection directives must be taken into consideration.
Shielding and doors must be closed during operation so that the efficiency of the
sound insulating is not reduced.
Safety measure required
The growth and spread of bacteria must be prevented by corresponding service
and water treatment methods.
Have the cooler checked regularly by specially trained technicians.
Strictly observe the relevant wastewater regulations.
Cooling water must not be drained in an uncontrolled manner into public sewage
systems.
Uncontrolled overflowing of the oil separation reservoir into public sewage
systems must be ruled out.
