Installation and maintenance instructions geoTHERM 0020250181_00
The heat pump itself does not have a frost
protection function. For smooth operation
of the refrigeration circuit, a minimum room
temperature of 7 °C must be maintained. If
the room temperature falls below 7 °C, this
may lead to frost damage on the heat pump.
1.2.14 Frost damage caused by
insufficient room temperature
If the room temperature is set too low in in-
dividual 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 in-
structions.
1.2.15 Frost damage as a result of a power
cut
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 gen-
erator to maintain the operational readiness
of the product during a power cut, note the
following:
▶
Make sure that the technical values of this
emergency power generator (frequency,
voltage, earthing) match those of the
power grid.
1.2.16 Material damage due to unsuitable
installation surface
The installation surface must be even and
have sufficient load-bearing capacity to sup-
port the operating weight of the product. An
uneven installation surface may cause leaks
in the product. If the installation surface does
not have sufficient load-bearing capacity, the
product may become detached and fall off.
There is a risk of death if the connections are
subject to leaks.
▶
Make sure that the product is positioned
flush against the installation surface.
▶
Ensure that the installation surface has
sufficient load-bearing capacity to bear the
operating weight of the product.
1.2.17 Risk of material damage caused by
using an unsuitable tool
▶
Use the correct tool to tighten or loosen
threaded connections.
1.2.18 Product fault as a result of 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.
▶
The system pressure instructions must be
observed.
1.2.19 Avoid environmental damage
caused by escaping refrigerant
The product contains R 410 A refrigerant.
The refrigerant must not be allowed to es-
cape into the atmosphere. R410A is a fluor-
inated 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 CO

.
Before the product is disposed of, the refri-
gerant that is contained in it must be com-
pletely drained into a suitable vessel so that
it can then be recycled or disposed of in ac-
cordance with regulations.
▶
Ensure that only officially certified com-
petent persons with appropriate protective
equipment carry out maintenance work on
the refrigerant circuit or access it.
▶
Arrange for the refrigerant that is contained
in the product to be recycled or disposed
of by a certified competent person in ac-
cordance with the regulations.

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 brine-to-water heat pump is designed for
use as a heat generator for closed heating
installations. The product is intended exclus-
ively for domestic use as a heat generator for
closed central heating installations. Operating
the product outside the operating limits res-
