1.2.2 Risk of death due
to explosions and
scaldings from brine
fluid
The brine fluid ethylene and
propylene glycol is extremely
flammable, both as liquid and
steam. A potentially explosive
combination of steam/air may
form.
▶ Keep away from heat, sparks,
naked flames and hot surfaces.
▶ Prevent steam/air mixtures
from forming. Keep brine fluid
vessels closed.
▶ Observe the safety data sheet

The brine fluid ethylene glycol is
harmful to health.
▶ Avoid contact with the skin

1.2.5 Preventing the risk of
injury due to scalding
from hot and cold

temperatures.
▶ Select the temperature so
that nobody is at risk.
1.2.7 Risk of death due to lack
of safety devices
A lack of safety devices (e.g.
expansion relief valve, expansion vessel) can lead to potentially fatal scalding and other
injuries, e.g. due to explosions.
▶ Have your competent person
check that all required isolator
devices are present in your
heating installation.
1.2.8 Preventing the risk of
injury from freezing

▶ Never interfere or tamper with
the product or other parts of
the system.
▶ Never try to carry out maintenance work or repairs on
the product yourself.
▶ Do not damage or remove
any seals on components.
Only qualified competent

1 Safety
Frost protection and monitoring
devices are only active while
the product is connected to
the power supply. The product
must be connected to the power
supply.
1.2.12 Frost damage caused
by 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.
▶ If you are going to be away
during a cold period, ensure
that the heating installation
remains in operation and that
the rooms are sufficiently
heated.
▶ You must observe the frost
protection instructions.
1.2.13 Frost damage caused
by a power cut
During installation, your competent person connected your
product to the power mains.
If the power supply is cut, it is
possible that parts of the heating installation may become
damaged by frost. If you want
to use an emergency power
generator to maintain the operational readiness of the product

during a power cut, note the following:
▶ Contact your competent person for advice on installing an
emergency power generator.
▶ Ensure that the technical values of this generator (frequency, voltage, earthing)
match those of the power
mains.
1.2.14 Malfunction caused
by incorrect system
pressure
To avoid operating the system
with too little water and thus
prevent resulting damage, note
the following:
▶ Check the system pressure
of the heating installation at
regular intervals.
▶ You must observe the system
pressure instructions.
1.2.15 Malfunction due to
incorrect power supply
The power supply must remain
within the specified limits so that
the product does not malfunction:
– 1 phase: 230 V (+10/-15%)
~50 Hz
– 3 phases: 400 V (+10/-15%) 3
N ~50 Hz

Safety 1
1.2.16 Avoid environmental
damage caused by
escaping coolant
The product contains R410A
coolant. 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 1725 (GWP = Global
Warming Potential). If this gas
escapes into the atmosphere,
its impact is 1725 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
it can then be recycled or disposed of in accordance with
regulations.
▶ Ensure that only officially certified competent persons with
appropriate protective equipment carry out maintenance
work on the coolant circuit or
access it.
▶ Arrange for the coolant contained in the product to be
recycled or disposed of by
certified competent persons in
accordance with regulations.

3. Do not clean the product with a highpressure cleaner.
4. At regular intervals, check that no
branches or leaves have gathered
around the product.

Danger!
Risk of injury and risk of material damage due to neglected or incorrect maintenance and repairs.
Neglected or incorrect maintenance work or repairs may lead
to personal injury or damage to
the product.
▶
▶
If, during long periods of absence, the
power supply to the dwelling and to the
product is interrupted, have the heating system drained by your competent
person or have it sufficiently protected
against frost.
6 Troubleshooting
Never attempt to carry out

on the product.
Employ an authorised heating specialist company to
complete such work. We recommend making a maintenance agreement.

Fault messages have priority over all other
displays and are shown instead of the basic display. If several faults occur at the
same time, these are each displayed alternately for two seconds each.

your product by a competent person
is a prerequisite for ensuring that the
system is constantly ready and safe
for operation, reliable and has a long
service life.

Note
Failure to carry out maintenance and repair work, and noncompliance with the specified
inspection, maintenance and
replacement intervals, leads to
a loss of potential guarantee
