changes to the product or
the product environment
▶Never remove, bridge or
block the safety devices.
▶Do not tamper with any of the
safety devices.
▶Do not damage or remove
any tamper-proof seals on
components.
▶Do not make any changes:
–The product itself
–The water and electricity
supply lines
–to the expansion relief valve
–to the drain pipework
–to constructional condi-
tions that may affect the
operational reliability of the
product
1.5 Risk of burns caused by
touching hot surfaces
The outgoing lines and hy-
draulic connections are hot dur-
ing operation.
▶Do not touch any hydraulic
connections.
▶Do not touch any air inlets or
outlets.
1.6 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 60 °C. Young
children and elderly persons are
particularly at risk, even at lower
temperatures.
▶Select the temperature so
that nobody is at risk.
1.7 Preventing the risk of
injury from freezing
as a result of touching
refrigerant
The product is delivered with an
operational filling of R 290 re-
frigerant. This is a chlorine-free
refrigerant which does not affect
the Earth's ozone layer. Escap-
ing refrigerant may cause freez-
ing if the exit point is touched.
▶If refrigerant escapes, do not
touch any components of the
product.

1.10 Dangers of modifying
product surroundings
Some types of installation and
conversion work in your home
can impair the way your product
operates.
▶Consult your installer before
undertaking the work in ques-
tion.
1.11 Frost damage due to
insufficient room
temperature
If the room temperature is set
too low in individual rooms, it
cannot be ruled out that sec-
tions of the heating installation
might be damaged by frost.
The product may release cold
air into the room. This means
the room temperature can fall
below 0 °C.
▶If you are going to be away
while the outside temperature
is low, ensure that the heating
installation remains in oper-
ation and that the rooms are
sufficiently heated.
▶You must observe the frost
protection instructions.
