Viessmann products can be recycled. Components
and substances from the system are not part of ordi-
nary household waste.
Isolate the system from the power supply for decom-
missioning. Allow any hot components to cool down.
All components must be disposed of correctly.
DE:
We recommend using the disposal system organ-
ised by Viessmann. Operating fluids (e.g. heat
transfer medium) can be disposed of at municipal
collection points. Viessmann sales offices can
provide further information.
Extracting the refrigerant
Decommissioning may only be carried out by a quali-
fied contractor who is familiar with the equipment used
for refrigerant disposal.
We recommend recovering the refrigerant. For this,
take oil and refrigerant samples before decommission-
ing the heat pump.
Before commencing work, observe the "Checklist for
maintenance work" on page 60.
Also take into account the following points:
■
Only use extraction equipment which is suitable for
R290.
Check the condition of the extraction equipment,
including the service record.
All electrical components of the extraction equipment
must be suitable for operation in flammable atmos-
pheres.
■
Only use refrigerant bottles suitable for R290, e.g.
special recycling bottles. The refrigerant bottles must
be correspondingly labelled.
The refrigerant bottles must be equipped with a
safety valve and permanently attached shut-off
valves.
■
Check whether a sufficient number of recycling bot-
tles is available.
■
Evacuate and cool any empty refrigerant bottles.
■
Do not mix together different refrigerants in a single
recycling bottle.
■
Have suitable transport equipment ready for the
refrigerant bottles (if required).
■
Check the availability of personal protective equip-
ment and its proper use.
■
Check whether the waste treatment areas and the
refrigerant bottles correspond to the relevant direc-
tives.
■
Provide calibrated scales to determine the amount of
extracted refrigerant.

1.
Check the condition of the heat pump. Check
whether the service intervals have been adhered
to.
0
2.
Isolate the system from the power supply.

3.
Check whether the safety instructions for work on
the refrigerant circuit are being adhered to: See
page 3.

4.
Place the refrigerant bottle on the scales.

5.
Connect the refrigerant bottle to the extraction
equipment. Connect the extraction equipment to
the refrigerant circuit via a manifold.
0
6.
Extract the refrigerant from all parts of the refriger-
ant circuit using the extraction equipment.
Note
■
The refrigerant extraction must be continuously
monitored by an authorised contractor.
■
Do not overfill the refrigerant bottle, max. 80 %
of the permissible capacity.
■
Do not exceed the permissible design pressure
of the refrigerant bottle.
0
7.
Close the shut-off valves after the refrigerant has
been fully extracted.
0
8.
Switch off the extraction device.
0
9.
Separate the refrigerant bottle from the refrigerant
circuit. Take the refrigerant bottle to the waste
treatment area.
10.
Clean and check the recovered refrigerant. Do not
mix the refrigerant with other refrigerants.
11.
Affix a label to the heat pump in a clearly visible
position, containing the following information, with
date and signature:
■
Refrigerant is flammable.
■
The system has been taken out of use.
■
The refrigerant has been removed.
Disposing of the compressor and compressor oil
1.
To ensure that no flammable refrigerant is in the
compressor, evacuate the compressor with suffi-
cient negative pressure before draining off the oil.
2.
Take care when draining the oil from the compres-
sor. Speed up this process with an electric ribbon
heater if required.
3.
Dispose of the oil in a suitable location.
