– Fernox F2
– Sentinel X 100
– Sentinel X 200
Additives for frost protection intended to remain
permanently in the system
– Fernox HP 15 or HP15c
– Sentinel X 500
▶ Inform the operator about the measures required if you
have used these additives.
▶ Inform the operator about the measures required for frost
protection.
Permissible water hardness
Note
Contact the local water supply company for further
information on water quality.
▶ Observe all applicable national regulations and technical
standards when treating the filling and supplementary
water.
Provided the national regulations and technical standards
do not stipulate more stringent requirements, the following
applies:
You must treat the heating water in the following cases:
– If the entire filling and supplementary water volume dur-
ing the operating life of the system exceeds three times
the nominal volume of the heating installation,
– If the limit values shown in the following tables are not
observed.

1) Of the specific system volume (nominal capacity in
litres/heating output; on systems with more than one boiler, the
lowest individual heating output must be set). These values only
apply up to three times the system volume for filling and supple-
mentary water. If three times the system volume is exceeded,
the water must be treated in accordance with the specifications
from the VDI (softening, desalting, hardness stabilisation or
blowing down). This is exactly the same as if the limit values in
the table were exceeded

6.4 Filling the heating installation
Caution.
Risk of material damage due to heating
water that is extremely calciferous or cor-
rosive or contaminated by chemicals.
Unsuitable tap water damages the seals
and diaphragms, blocks components in the
product and heating installation through
which the water flows and causes noise.
▶ Only fill the heating installation with suit-
able heating water.
Note
If a heat exchanger module is used, the heating
circuit must be topped up with heating water.
Conditions: System separation with a heat exchanger module
▶ Connect the filling cock with the heating water supply
using a cold water valve where possible.
▶ Open all radiator valves (thermostatic radiator valves) of
the heating installation.
▶ Open the cold water valve.
▶ Slowly open the filling cock.
▶ Fill it with water until the required filling pressure is
reached.
▶ Close the cold water valve.
▶ Purge all radiators.
▶ Then check the filling pressure on the display.
▶ Top up with more water if necessary.
▶ Close the filling cock.
6.5 Activating the heat pump
1. Ensure the maximum flow temperature setting matches
the heating installation.
2. To fully activate the heating installation, observe the
installation instructions for the system controller.
3. Switch on the line protection switch in the fuse box
which is connected to the heat pump.
6.6 Checking the product's operation
1. Ensure that the external control equipment (thermo-
stats, external sensors, etc.) are sending a heating
demand to the heat pump. When configuring several
areas, test heating circuit by heating circuit and ensure
that the appropriate heating circuit gets warmer.
2. Ensure that all heating circuit thermostatic radiator
valves are open.
3. If necessary, balance the heat generator.
