Heating system
Particle filter (integrated in E6 - 11)
A particle filter for the heating system is included in the delivery of C6-
C11 and should be installed on the connection for the heating system's
return line.
Heat carrier pump
Factory setting for the heat carrier pump is ext. in (
Æ
Figure 18). The
factory setting (ext. in) on the heat carrier pump must not be changed
using the dial, the pump settings are controlled from the control unit.

Propylene glycol
Glycol is not normally used in the heating system. In special cases, where
increased protection is required, glycol can be added with a maximum
concentration of 15%. Heat pump performance will however decrease.
Safety valve
Pursuant to EN 12828, a safety valve should be used.
The safety valve should be installed vertically.
9.3
Siting the appliance
Noise transfer to adjacent areas must be taken into consideration when
choosing a position for the heat pump (
Æ
Chapter 7.3 for sound
levels).
9.4
Pipework preparations
B
Connection pipes for the collector system, heating system and
possible hot water should be installed in the premises to the heat
pump location.
B
An expansion vessel, a safety group and a pressure gauge should be
mounted in the heating circuit (accessories).
B
Mount the filling unit in a suitable place in the collector circuit.
9.5
Flushing out the heating system
The heat pump is a part in a heating system. Faults in the heat pump can
be caused by poor water quality in the radiators/floor loops or air
penetrating the system continuously.
Oxygen causes corrosion products in the form of magnetite and
sediment.
Magnetite has a grinding effect on the heating system's pumps, valves
and components with turbulent flows such as the condenser.
Heating systems which require regular filling or where the heating water
is not clear when drained, require remedial measures before the
installation of a heat pump, for example the heating system must be
fitted with filters and vents.
Do not use any water treatment additives except agents for raising the
pH level. Recommended pH value is 7.5 – 9.
An intermediate heat exchanger is sometimes necessary to protect the
heat pump.
9.6
Setting up
B
Remove packing, taking care to observe the instructions on the
packing.
B
Remove the supplied accessories.
B
Install the supplied adjustable feet and adjust the height.
9.7
Heat insulation
All heat transfer and collector circuits must have suitable heat and
condensation insulation according to applicable norms.
WARNING:
B
No other anti-freeze may be used in the heating
system.
WARNING:
B
Never block the safety valve outlet.
