d Danger!
Risk to life as a consequence of improper
use of the installation.
There is a risk of death or serious injury
to the user or third parties or of damage
to the device and other property in the
event of improper use or use for which it
is not intended.
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.
h Note!
Clean the exterior of your heat pump
with a damp cloth and a little soap.
3.4 Checking the operating condition of the heat
pump
In contrast to heaters that operate using fossil fuels, no
complex maintenance work is necessary for the Vaillant
geoTHERM exclusive heat pump.
h Note!
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 installation
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.
a Caution!
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.
h Note!
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
reading 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 auto-
matically and an error message will be displayed.
a Caution!
Risk of damage from brine escaping from
leaks in the system.
In the event of leaks in the brine circuit
switch off the heat pump to avoid any
further leaking.
Have the leaks repaired by an expert
technician.
a Caution!
The brine circuit must be filled with the
correct quantity of fluid; otherwise the
system can be damaged.
If the filling level of the brine has fallen so far that it is
no longer visible in the expansion tank, you must have
the brine refilled.
