– compliance with all inspection
and maintenance conditions
listed in the instructions.
This product can be used by
children aged from 8 years
and above and persons with
reduced physical, sensory or
mental capabilities or lack of
experience and knowledge if
they have been given supervision or instruction concerning
use of the product in a safe way
and understand the hazards involved. Children must not play
with the product. Cleaning and
user maintenance work must
not be carried out by children
unless they are supervised.
Any other use that is not specified in these instructions, or
use beyond that specified in this
document, shall be considered
improper use. Any direct commercial or industrial use is also
deemed to be improper.
Caution.
Improper use of any kind is
prohibited.

cause material damage.
▶ Carefully read the enclosed
instructions and all other applicable documents, particularly the "Safety" section and
the warnings.
▶ Only carry out the activities
for which instructions are
provided in these operating
instructions.

▶ If possible, open doors and
windows fully and ensure
adequate ventilation.
▶ Do not use naked flames (e.g.
lighters, matches).
▶ Do not smoke.
▶ Do not use any electrical
switches, mains plugs, doorbells, telephones or other
communication systems in
the building.
▶ Leave the building immedi-
ately and ensure that others
do not enter the building.
1.4 Risk of death due to
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 hydraulic connections are hot during 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 refrigerant. This is a chlorine-free
refrigerant which does not affect
the Earth's ozone layer. Escaping refrigerant may cause freezing if the exit point is touched.
▶ If refrigerant escapes, do not
touch any components of the
product.
1 Safety
6 Operating instructions aroSTOR 0020285064_00
▶ 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 refrigerant.
▶ In the event of skin or eye
contact with the refrigerant,
seek medical advice.
1.8 Risk of injury and
material damage due to
maintenance and repairs
carried out incorrectly or
not carried out at all
▶ Never attempt to carry out
maintenance work or repairs
on your product yourself.
▶ Faults and damage should
be immediately rectified by a
competent person.
▶ Adhere to the maintenance
intervals specified.
1.9 Risk of damage from
corrosion caused by
unsuitable room air
Sprays, solvents, chlorinated
cleaning agents, paint, adhesives, ammonia compounds,
dust or similar substances
may lead to corrosion on the
product.
▶ Ensure that the air supply is
always free of fluorine, chlorine, sulphur, dust, etc.
▶ Ensure that no chemical sub-
stances are stored at the installation site.
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 question.
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 sections 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 operation and that the rooms are
sufficiently heated.
▶ You must observe the frost
protection instructions.

Before the product is disposed
of, the refrigerant that is contained in it must be completely
drained into a suitable vessel so
that it can then be recycled or
disposed of in accordance with
regulations.
▶ Ensure that only officially cer-
tified competent persons with
