a Caution!
Risk of damage from water escaping due
to leaks in the system.
Close the cold water stop valve in the
event of leaks in the hot water pipework.
De-energise the heat pump if the heating
installation is leaking (fuse off).
Have the leaks repaired by an expert
technician.
h Note
The cold water stop valve is not included
in the scope of delivery for the heat
pump. It is fitted on site by your heating
engineer. He will explain the location and
handling of the component to you.
5.10.2 Checking the filling level and filling pressure
of the brine circuit
Check the brine level or pressure in the brine circuit at
regular intervals.
• Read off the filling pressure of the brine circuit ("pres-
sure, heat source") at the heat pump controller (see
Fig. 5.5).
The brine filling pressure should be between 1 and 2 bar.
If it falls below 0.6 bar for 2 minutes, or falls below
0.2 bar once, the heat pump is automatically switched
off and an error message is displayed
(see Chap. 3.3 "Low brine pressure protection").
a Caution!
Risk of damage due to brine escaping
from leaks in the system.
De-energise the heat pump if the brine
circuit is leaking (fuse off).
Have the leaks repaired by an expert
technician.
a Caution!
Risk of damage.
The brine circuit must be filled with
the correct quantity of fluid; otherwise
the system can be damaged. Check the
filling level of the brine circuit at regular
intervals and inform your expert techni-
cian company if the filling level in the
brine expansion tank is too low. The
filling of the brine circuit in your heat
pump installation may only be under-
taken by authorised specialists.
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 replenished.

1 Filling level too low
2 Filling level correct
It is normal for the filling level of the brine to fall a little
in the first month after the start-up of the system. The
filling level can also vary depending on the temperature
of the heat source. However it should never sink so far
that it is no longer visible in the expansion tank.
5.11 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.
