▶
Observe the applicable national and inter-
national laws, standards and directives.
1.3.4 Risk of death from electric shock
There is a risk of death from electric shock if
you touch live components.
Before commencing work on the product:
▶
Disconnect the product from the power
supply by switching off all power supplies
at all poles (electrical partition in over-
voltage category III for full partition, e.g.
fuse or circuit breaker).
▶
Secure against being switched back on
again.
▶
Wait for at least 3 minutes until the capa-
citors have discharged.
▶
Check that there is no voltage.
1.3.5 Risk of burns, scalds and frostbite
due to hot and cold components
There is a risk of burns and frostbite from
some components, particularly uninsulated
pipelines.
▶
Only carry out work on the components
once these have reached environmental
temperature.
1.3.6 Risk of injury from freezing caused
by touching refrigerant
The product is delivered with an operational
filling of R410A refrigerant. Escaping refri-
gerant may cause freezing if the exit point is
touched.
▶
If refrigerant escapes, do not touch any
components of the product.
▶
Do not inhale any vapours or gases that
escape from the refrigerant circuit as a
result of leaks.
▶
Avoid skin or eye contact with the refriger-
ant.
▶
In the event of skin or eye contact with the
refrigerant, seek medical advice.
1.3.7 Risk of environmental damage
caused by escaping refrigerant
The product contains the refrigerant R410A.
This refrigerant must not be allowed to es-
cape into the atmosphere. R410A is a fluor-
inated greenhouse gas covered by the Kyoto
Protocol, with a GWP of 2088 (GWP = Global
Warming Potential). If this gas escapes into
the atmosphere, its impact is 2088 times
greater than the natural greenhouse gas CO
2
.
Before the product is disposed of, the refri-
gerant that is contained in it must be com-
pletely drained into a suitable vessel so that
it can then be recycled or disposed of in ac-
cordance with regulations.
▶
Ensure that only an officially certified com-
petent person with appropriate protective
equipment carries out installation or main-
tenance work or any other form of inter-
vention on the refrigerant circuit.
▶
Arrange for the refrigerant that is contained
in the product to be recycled or disposed
of by a certified competent person in ac-
cordance with the regulations.
1.3.8 Risk of material damage caused by
using an unsuitable tool
▶
Use the correct tool.
1.3.9 Risk of material damage caused by
using an unsuitable material
Unsuitable refrigerant pipes may cause ma-
terial damage.
▶
Only use special copper pipes designed
for refrigeration technology.
1.4
Regulations (directives, laws,
standards)
▶
Observe the national regulations, stand-
ards, directives, ordinances and laws.
