3 Notes on the installation and operation
Caution!
a
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.
Caution!
a
Risk of damage!
The brine circuit must be filled with the
correct quantity of fluid; otherwise the
system can be damaged.
Caution!
a
Risk of damage!
The filling of the brine circuit in your
heat pump installation may only be un-
dertaken by authorised specialists.
Check the filling level of the brine circuit
at regular intervals and inform your ex-
pert technician company if the filling
level in the brine expansion tank is too
low.
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.
Fig. 3.1 Filling level of the brine expansion tank
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.

3.4.3 Accumulation of condensate
(condensation water)
The evaporator, the brine pumps and the pipes in the
heat source circuit, as well as some components in the
coolant circuit, are insulated in the interior of the heat
pump, so that no condensate can accumulate. If conden-
sate should ever accumulate in small amounts this will
be collected by the condensate basin. The condensate
basin is located on the inside, in the lower part of the
heat pump. As a result of the heat generated inside the
heat pump, the condensate in the condensate pan evap-
orates. Small amounts of the accumulating condensate
can be drained off under the heat pump. In small
amounts, accumulating condensate should not be seen
as a fault in the heat pump.

Energy saving tips

Below you will find important tips to help you operate
your heat pump system in an energy and cost-saving
manner.
3.5.1

General energy saving tips

You can even save energy by your general behaviour:
— Ventilate correctly:
Do not leave windows or French windows tilted open,
but rather open the windows wide 3 to 4 times a day
for 15 minutes and turn down the thermostatic valves
or room thermostats while ventilating.
— Do not block the radiators to ensure that heated air
can circulate in the room.
— Use a ventilation system with heat recovery.
The optimum exchange of air in the building is always
guaranteed by the use of a ventilation system with
heat recovery (windows no longer need to be opened
for ventilation purposes). If necessary, the air flow can
be matched to your individual requirements with the
ventilation unit's remote control.
— Check that windows and doors are airtight: Keep shut-
ters and blinds closed at night, so that as little heat as
possible is lost.
— If a VR 90 remote control unit is installed as an acces-
sory, do not obstruct it with furniture, etc., so that it
can measure the circulating room air unhindered.
— Think when using water, for example, take a shower
instead of a bath, promptly renew the seals on drip-
ping taps.
