tact gap of at least 3 mm, e.g. fuse or cir-
cuit 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 material damage due to an
unsuitable installation surface
An uneven installation surface may cause
leaks in the product.
▶
Make sure that the product is positioned
flush against the installation surface.
▶
Ensure that the installation surface has
sufficient load-bearing capacity to bear the
operating weight of the product.
1.3.6 Risk of material damage due to
malfunctioning
Not rectifying faults, changing the safety
devices and failing to carry out maintenance
can cause malfunctioning and pose safety
risks during operation.
▶
Ensure that the heating installation is in a
technically perfect condition.
▶
Ensure that no safety or monitoring
devices have been removed, bridged or
disabled.
▶
Immediately eliminate any faults and dam-
age that may affect safety.
1.3.7 Preventing the risk of injury from
freezing as a result of touching
refrigerant
The refrigeration circuit for the indoor unit is
delivered with an operational filling of nitro-
gen in order to guarantee a check for tight-
ness. The outdoor unit is delivered with an
operational filling of R410A refrigerant. Es-
caping refrigerant may cause freezing if the
exit point is touched.
▶
If refrigerant escapes, do not touch any
components of the product.
▶
Do not inhale any steam 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.
1.3.8 Risk of material damage caused by
condensate inside the house
In heating mode, the lines between the heat
pump and the heat source (environment cir-
cuit) are cold, which means that condensate
may form on the lines in the house. In cooling
mode, the lines in the building circuit are so
cold that condensate may form if the temper-
ature falls below the dew point. Condensate
may lead to material damage, for example
due to corrosion.
▶
Ensure that you do not damage the heat
insulation on the lines.
1.3.9 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 they have reached environmental
temperature.
1.3.10 Risk of being scalded by hot drinking
water
There is a risk of scalding at the hot water
draw-off points if the hot water temperatures
are greater than 50 °C. Young children and
elderly persons are particularly at risk, even
at lower temperatures.
▶
Select the temperature so that nobody is at
risk.
1.3.11 Risk of material damage due to
additional elements in the heating
water
Unsuitable frost and corrosion protection
agents may damage seals and other com-
ponents of the heating circuit and may there-
fore also lead to leaks in the water outlet.
▶
Only add approved frost and corrosion
protection agents to the heating water.
1.3.12 Risk of material damage caused by
frost
▶
Do not install the product in rooms prone
to frost.
