Otherwise, under unfavourable operating conditions, injury,
death or material damage may occur.
Preventing explosions and burns
The brine fluid ethanol is extremely flammable, both as liq-
uid and steam. A potentially explosive combination of
steam/air may accumulate.
>
Keep away from heat, sparks, naked flames and hot sur-
faces.
>
Ensure that there is sufficient ventilation in the event of
accidental release.
>
Avoid the accumulation of steam/air mixtures. Keep
brine fluid containers closed.
>
Observe the safety data sheet that accompanies the
brine fluid.
The components of the heat pump can reach high tempera-
tures.
>
Do not touch any uninsulated pipelines in any part of the
heating installation.
>
Do not remove any cover parts.
Preventing chemical burns (VWS only)
The brine fluid ethylene glycol is harmful to health.
>
Avoid contact with the skin and eyes.
>
Always wear gloves and protective goggles.
>
Do not inhale or swallow.
>
Observe the safety data sheet that accompanies the
brine fluid.
Preventing freezing
The heat pump is delivered with an operational filling of R
407 C coolant. This is a chlorine-free coolant which does
not affect the Earth‘s ozone layer. R 407 C is neither a fire
hazard nor an explosion risk.
Escaping coolant can cause freezing if the exit point is
touched.
>
If coolant escapes, do not touch any components of the
heat pump.
>
Do not inhale any steam or gases that escape from the
coolant circuit as a result of leaks.
>
Avoid skin and eye contact with the coolant.
>
In the event of skin or eye contact with the coolant, seek
medical advice.
Preventing injury as a result of unauthorised mod-
ifications
For alterations to the heat pump or its peripherals, you
must call on a qualified heating engineer. Unauthorised
modifications to the heat pump and its peripherals can lead
to improper operation and thereby unnecessary dangers.
>
Do not damage or remove seals or locking devices on
components. Only a suitably qualified heating engineer
or our customer service may modify sealed components.
The prohibition applies to:
– the heat pump,
– the vicinity of the heat pump,
– the supply lines for water and power.
>
Under no circumstances should you attempt to make
changes or alterations to the heat pump or other parts
of the heating and hot water system yourself.
>
Do not make any subsequent structural alterations which
may result in a reduced room volume or a change to the
temperature at the installation site of the heat pump.
Preventing environmental hazards
The heat pump contains the coolant R 407 C. The coolant
must not be allowed to escape into the atmosphere. R 407 C
is a fluorinated greenhouse gas covered by the Kyoto Proto-
col, with a GWP of 1653 (GWP = Global Warming Potential).
If it escapes into the atmosphere, its impact is 1653 times
stronger than natural greenhouse gas CO
2
.
Before the heat pump is disposed of, the coolant it contains
must be completely drained into a suitable vessel so that it
can then be recycled or disposed of in accordance with the
regulations.
>
Ensure that only officially certified specialists with
appropriate protective equipment perform maintenance
work or access the coolant circuit.
>
The coolant in the heat pump must only be recycled or
disposed of by certified specialists in accordance with
the regulations.
If external passive cooling is installed:
Preventing material damage due to condensation
The heating flow temperature must not be set too low
in cooling mode, as otherwise condensation can accumulate
in the heat pump and escape beneath it. Even with
a max. flow setpoint of above 20 °C, the cooling function is
still effective.
>
Do not set the heating flow temperature lower than
20 °C.
