ation components

–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 supervi-

sion or instruction concerning

use of the product in a safe way

and understand the hazards in-

volved. 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 spe-

cified in these instructions, or

use beyond that specified in this

document, shall be considered

improper use. Any direct com-

mercial or industrial use is also

deemed to be improper.

Caution.

Improper use of any kind is

prohibited.

1.2 Danger caused by

improper operation

▶Carefully read the enclosed

instructions and all other ap-

plicable documents, particu-

larly the "Safety" section and

the warnings.

▶Only carry out the activities

for which instructions are

provided in these operating

instructions.

1.3 Risk of death caused by

escaping refrigerant

The product contains R 290

refrigerant.

R 290 is an inflammable refri-

gerant.

When refrigerant escapes, there

is a risk of explosion.

Safety 1

▶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, door-

bells, telephones or other

communication systems in

the building.

▶Leave the building immedi-

ately and ensure that others

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 Safety

6Operating 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

intervals specified.

1.9 Risk of damage from

corrosion caused by

unsuitable room air

Sprays, solvents, chlorinated

cleaning agents, paint, adhes-

ives, ammonia compounds,

dust or similar substances

may lead to corrosion on the

product.

▶Ensure that the air supply is

always free of fluorine, chlor-

ine, sulphur, dust, etc.

▶Ensure that no chemical sub-

stances are stored at the in-

stallation 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 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.

the atmosphere.

Before the product is disposed

of, the refrigerant that is con-

tained in it must be completely

drained into a suitable vessel so
