1.2 General safety
information

1.2.1 Intended use

There is a risk of injury or death
to the user or others, or of dam­age to the product and other
property in the event of im­proper use or use for which it
is not intended.

The system is intended exclus­ively for domestic use.

The system is intended as a
heat generator with cooling
function for closed central heat­ing installations and for hot wa­ter generation. Operation of
the pump outside the applic­ation limits results in the heat
pump being switched off by
the internal control and safety
devices.

Cooling mode with radiator
heating systems is not permit­ted since radiators do not have
an adequate heat transfer sur­face area.

Intended use includes the fol­lowing:

– observance of the operating

instructions included for the
product and any other system
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 supervi­sion or instruction concerning
use of the product in a safe way
and understand the hazards in-

volved. Children shall not play
with the product. Cleaning and
user maintenance shall not be
made by children without super­vision. 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.

1.2.2 Danger caused by
improper operation

Improper operation may present
a danger to you and others, and
cause material damage.

▶ Carefully read the enclosed

instructions and all other ap­plicable documents, particu­larly the "Safety" section and
the warnings.

1.2.3 Risk of death due to
explosive and flammable
materials

▶ Do not use or store explosive

or flammable materials (e.g.

petrol, paper, paint) in the in­stallation room of the product.

1.2.4 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 seals on components.
Only authorised competent
persons or customer services
may modify sealed compon­ents.

▶ Do not make any changes to:

– The product itself
– The product environment
– The brine fluid, air and elec-

tricity supply lines

– The drain line and expan-

sion relief valve for the heat
source circuit

– The constructional condi-

tions that may affect the
operational reliability of the
product

1.2.5 Risk of injury due to
chemical burns caused
by brine fluid

The brine fluid ethylene glycol is
harmful to health.

▶ Avoid contact with the skin

and eyes.

Safety 1

0020213396_00 flexoTHERM Operating instructions 5

▶ Always wear gloves and pro-

tective goggles.

▶ Do not inhale or swallow.
▶ Observe the safety data sheet

that accompanies the brine
fluid.

1.2.6 Preventing the risk of
injury from freezing
as a result of touching
coolant

The product is supplied with an
operational filling of R 410 A
refrigerant. Escaping coolant
may cause freezing if the exit
point is touched.

▶ If coolant escapes, do not

touch any components of the
product.

▶ Do not inhale any vapours or

gases that escape from the
refrigerant circuit as a result
of leaks.

▶ Avoid skin or eye contact with

the coolant.

▶ In the event of skin or eye

contact with the coolant, seek
medical advice.

1.2.7 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.

1.2.8 Risk of material damage
caused by frost

▶ Ensure that the heating in-

stallation always remains in
operation during freezing con­ditions and that all rooms are
sufficiently heated.

▶ If you cannot ensure the op-

eration, have a competent
person drain the heating in­stallation.

1.2.9 Avoid environmental
damage caused by
escaping coolant

The product contains R 410 A
refrigerant. The coolant must
not be allowed to escape into
the atmosphere. R410A is a
fluorinated greenhouse gas
covered by the Kyoto Protocol,
with a GWP of 2088 (GWP =
global warming potential). If
this gas escapes into the atmo­sphere, its impact is 2088 times
greater than the natural green­house gas CO2.

Before the product is disposed
of, the coolant that is contained
in it must be completely drained
into a suitable vessel so that

1 Safety

6 Operating instructions flexoTHERM 0020213396_00

it can then be recycled or dis­posed of in accordance with
regulations.

▶ Ensure that only officially cer-

tified competent persons with
appropriate protective equip­ment carry out maintenance
work on the refrigerant circuit
or access it.

▶ Arrange for the refriger-

ant that is contained in the
product to be recycled or
disposed of by a certified
competent person in accord­ance with the regulations.
