Caution.
Risk of material damage if the heating
water is treated with unsuitable additives.
Unsuitable additives may cause changes in
the components, noises in heating mode and
possibly subsequent damage.
▶
Do not use any unsuitable frost and cor-
rosion protection agents, biocides or seal-
ants.
No incompatibility with our products has been detected to
date with proper use of the following additives.
▶
When using additives, follow the manufacturer's instruc-
tions without exception.
We accept no liability for the compatibility of any additive or
its effectiveness in the rest of the heating system.

▶
If you have used the above-mentioned additives, inform
the operator about the measures that are required.
▶
Inform the operator about the measures required for frost
protection.

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.
▶
Start the purging programme using the P10 and P11 test
programmes (
→
Page 28).
▶
Then check the filling pressure on the display.
▶
Top up with more water if necessary.
▶
Close the filling cock.

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.
6.10
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.
