Final decommissioning and disposal
The products may be recycled.
The components and consumables must not be disposed of in municipal waste.
To decommission the installation, disconnect the electrical supply and allow the components to cool down.
All the components must be expertly disposed of.
Consumables (e.g. heating mediums) may be disposed of with municipal waste.
Refrigerant suction
The heat pump may only be decommissioned by a specialist who is familiar with refrigerant disposal equipment. We recommend
recovering the refrigerant. For this purpose, oil and refrigerant samples must be taken before the heat pump is switched off.
Before starting the work, check the installation in accordance with the "Checklist in relation to keeping the device in good
technical shape".
Consider the following:
■
Only equipment that is suitable for the suction of the R32 refrigerant may be used.
Check the condition of the suction equipment, also include confirmation of maintenance.
All the electrical components of the suction equipment must be suitable for use in a flammable atmosphere.
■
Use only those cylinders that are suitable for storing the R32 refrigerant, i.e. special recyclable cylinders. The aforementioned
cylinders must be marked appropriately.
Refrigerant cylinders must possess a safety valve and shut-off valves that are permanently installed.
■
Check that the correct number of cylinders is available.
■
Cool down emptied refrigerant cylinders.
■
Do not mix different refrigerants in the same cylinder.
■
Prepare suitable means for transporting the refrigerant cylinders (if necessary).
■
Check the availability of personal protective equipment and how to use it correctly.
■
Check that disposal facilities and refrigerant cylinders meet relevant requirements.
■
Prepare a calibrated scale to determine the amount of refrigerant sucked.
1. Check the condition of the heat pump. Check that maintenance has been regularly conducted.
2. Unplug the installation.
3. Check that the safety requirements for work on the refrigeration circuit are met.
4. Place the refrigerant cylinder on the scale.
5. Connect the refrigerant bottle to the suction equipment. Connect the suction equipment to the refrigeration circuit using
the collection line.
6. Suck the refrigerant from all parts of the refrigeration circuit.
Tip
■
The suction process must be supervised at all times by a trained employee.
■
Do not overfill the refrigerant cylinder; max. 80% of the permissible amount.
■
Do not exceed the permissible operating pressure in the cylinder.
7. Close the shut-off valves after all the refrigerant has been sucked.
8. Power off the suction equipment.
9. Disconnect the cylinder from the refrigeration circuit. Send the refrigerant cylinder to a disposal facility.
10. Purify and check the recovered refrigerant. Do not mix the refrigerant with other refrigerants.
11. In a clearly visible location on the heat pump, attach a plate including the date and signature and the following information:
■
Flammable refrigerant
■
Installation is not working.
■
Refrigerant has been removed.
Disposal of the compressor and compressor oil
1. Before draining the oil, depressurise the compressor to a suitable negative pressure so that there is no flammable refrigerant
in the compressor.
2. Carefully drain the oil from the compressor. This process can be accelerated with an additional electric heater if necessary.
3. Dispose of the oil in a suitable place.
4. Return the compressor to the manufacturer.
