13 Decommissioning
4.
Use manual actuation to move the prioritising diverter
valve to the "Heating circuit/domestic hot water cylinder"
position.
5.
Open the stopcock on the filling device.
6.
Open the automatic air vent.
7.
Use the expansion relief valve to check whether the
heating circuit has been completely drained.
◁
Residual hot water may escape from expansion
relief valve's drain.
12.2
Draining the heating installation
1.
Connect a hose to the draining point of the installation.
2.
Route the free end of the hose to a suitable drainage
point.
3.
Ensure that the installation's service valves are open.
4.
Open the drain cock.
5.
Open the purging valves on the radiators. Start from
the highest radiator and then work from the top to the
bottom.
6.
Once the heating water has completely drained from
the installation, close the purging valves on all the radi-
ators and the drain cock again.
13 Decommissioning
13.1
Temporarily decommissioning the product
1.
Switch off the disconnector (circuit breaker) to which the
product is connected in the building.
2.
Disconnect the product from the power supply.
13.2
Permanently decommissioning the product
1.
Switch off the isolator (circuit breaker) to which the
product is connected in the building.
2.
Disconnect the product from the power supply.
Caution.
Risk of material damage when extracting
refrigerant.
When extracting refrigerant, there is a risk of
material damage caused by freezing.
▶
Ensure that heating water flows through
the indoor unit's condenser (heat ex-
changer) or it is completely drained when
extracting refrigerant on the secondary
side.
3.
Extract the refrigerant.
4.
Dispose of or recycle the product and its components.

14 Recycling and disposal
14.1
Recycling and disposal
Disposing of the packaging
▶
Dispose of the packaging correctly.
▶
Observe all relevant regulations.
14.2
Disposing of the product and accessories
▶
Do not dispose of the product or the accessories with
household waste.
▶
Dispose of the product and all accessories correctly.
▶
Observe all relevant regulations.
14.3
Disposing of the refrigerant
Warning.
Risk of damage to the environment.
The product contains the refrigerant R410A.
This refrigerant must not be allowed to es-
cape into the atmosphere. R410A is a fluor-
inated greenhouse gas covered by the Kyoto
Protocol, with a GWP of 2088 (GWP = Global
Warming Potential).
▶
Before the product is disposed of, have
the refrigerant which it contains com-
pletely drained into a suitable vessel so
that it can then be recycled or disposed of
in accordance with regulations.
Caution.
Risk of damage caused by defrosting.
Draining off the refrigerant generates intense
cooling of the indoor unit's plate heat ex-
changer, which may lead to the de-icing of
the plate heat exchanger on the heating wa-
ter side.
▶
Drain the indoor unit on the heating water
side in order to prevent damage.
▶
Ensure that, during the refrigerant draining
of the plate heat exchanger on the heating
water side, there is sufficient flow-through.
▶
Ensure that the refrigerant is disposed of by a qualified
competent person.
