3.5 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.

3.6 Dangers present when loading/moving machines

Danger
Loose parts may fall off when lifting.
The compressor may fall if mistakes are
made when lifting.
Safety components may be damaged if
lifted incorrectly.
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 waste water 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.
Safety measure required
All loose parts must first be removed or secured; parts fitted so that they can
turn like doors etc. must be secured and made immobile.
Parts to be removed for transport purposes must be carefully refitted and
fixed again before putting the machine / installation back into operation.
Only use lifting tackle approved for the weight in question.
Observe the operating manual for the lifting tackle.
When heavy loads are being conveyed by means of hoisting gear, it is
imperative to keep well clear of the load in order to avoid accidents.
The person giving the instructions must be within sight or voice contact with
the operator.
Machines may only be hoisted correctly using hoisting gear in accordance
with the information in the operating manual (lifting spots for heavy-lift
facilities etc.)
To avoid damage to the system or external installations, the compressed air
connection, cooling water connection, condensate drain and electrical
connection should be isolated from external lines and hoses.
The system must be set up on a level surface with full contact between its
base frame and the supporting surface.
