3 Notes on the installation
and operation
The Vaillant geoTHERM heat pumps are state-of-the-art
appliances which have been constructed in accordance
with recognised safety regulations. Nevertheless, there
is still a risk of injury or death to the user or others or
of damage to the device and other property in the event
of improper use or use for which it is not intended.
This unit is not intended for use by persons (including
children) having limited physical, sensory or mental ca-
pacities or who have inadequate experience and/or
knowledge, unless supervised by a person responsible
for their safety or who has been given instructions from
them as to how to operate the unit.
Children must be watched to ensure that they do not
play with the unit.
Danger!
d
Risk to life as a consequence of using
unqualified personnel!
Installation, inspection and repair may
only be carried out by a qualified engi-
neer. In particular, working on the elec-
trical components and on the coolant
circuit requires an appropriate qualifica-
tion.
3.1

Intended use

The Vaillant geoTHERM heat pumps are intended as
heaters for closed hot water central heating installa-
tions and hot water generation. Any other use or ex-
tended use is considered to be improper. The manufac-
turer or supplier is not liable for any resulting damage.
The user alone bears the risk.
It is also considered as intended use to observe:
— the operating and installation instructions
— all other applicable documents
— adherence to the inspection and care conditions.
Caution!
a
Any improper use is forbidden.
3.2

Requirements of the installation site

The installation site must be dimensioned such that the
heat pump can be properly installed and maintained.
• Ask your heating engineer which currently applicable
national building regulations must be observed.
The installation site must be dry and generally frost-
proof.

3.3

Cleaning and care

Do not use any scouring or cleaning agents that could
damage the cladding.
Note!
h
Clean the exterior of your heat pump
with a damp cloth and a little soap.
3.4 Checking the operational condition of the
heat pump
In contrast to heaters based on fossil fuels, no expen-
sive maintenance work is necessary for the
Vaillant geoTHERM heat pump.
Note!
h
Have your installation checked regularly
by an expert technician company to en-
sure efficient operation of your heat
pump.
3.4.1

Filling pressure of the heating system

The filling pressure of the heating installation should be
checked at regular intervals. The filling pressure of the
heating installation can be checked from the reading on
the heat pump controller (see sect. 5.5). It should be be-
tween 1 and 2 bar. If the water pressure falls below
0.5 bar, the heat pump will be shut down automatically
and an error message will be displayed.
Caution!
a
Risk of damage from water escaping
from leaks in the system.
Close the cold water stop valve in the
event of leaks in the hot water pipework.
In the event of leaks in the heating in-
stallation switch off the heat pump to
avoid any further leaking.
Have the leaks repaired by an expert
technician.
Note!
h
The cold water stop valve is not part of
the heat pump scope of supply. It is fit-
ted on site by your heating engineer. He
will explain the location and handling of
the component to you.
3.4.2 Filling level and filling pressure of the brine
circuit
Check the brine level or pressure in the brine circuit at
regular intervals. The filling pressure of the brine circuit
("Pressure Heat Source") can be checked from the read-
ing on the heat pump controller (see sect. 5.5). It should
be between 1 and 2 bar. If the brine pressure falls below
0.2 bar, the heat pump will be shut down automatically
and an error message will be displayed.
