INFORMATION
To ensure proper and safe disposal activities, operator must equip themselves with the
necessary PPE including: anti-cut gloves, oil resistant gloves, heat resistant gloves, safety
footwear, safety eye-wear against liquid and gas splashes.
The context in which the unit is located may require the use of additional PPE, thus it is
mandatory to inquire with the relevant staff of the area before starting operation.
Once the materials have been separated as shown below, they should be assigned EWC codes and
then sent for disposal in accordance with the national legislation.
Disposal related to the unit purchased occurs in three stages:
1. Disposal of packaging
The packaging of the unit must be disposed of ensuring separation of the following materials:
• Paper and Cardboard
• Wood Packing–Packing materials are not chemically treated unless they are declared to be
“fumigate”
• Plastic pallets- high- density polyethylene HDPE
• Plastic Film– polyethylene PE
• Polystyrene –expanded polystyrene EPS 6
2. Disposal of substances during maintenance operations
• During the life cycle of the unit, if it becomes necessary to drain the cooling system, the refrigerant
must be recovered. This operation must be performed by qualified personnel in accordance with
UE Regulation 517/2014. The types of gases used are shown in the following table.
• If the compressor oil needs to be replaced, it must be disposed of according to the instructions
below.
• The air filters should be disposed of depending on the substances they contain from the
environment in which the units operate
• The gas filters must be disposed of as contaminated materials from the oils of the type shown below
3. Disposal at the end of life of the unit
The unit must be disposed of ensuring separation of the following materials:
• Refrigerant - The refrigerant must therefore be recovered before dismantling the unit. The types of
refrigerants used are the following:

• Metals
• Copper pipes– may contain traces of oil
• Insulation and sound-absorbing materials
• Electric and electronic components
• Cables and wiring
• Oil content within the compressors–is polyester based (POE). Refer to the label on the
compressor.
