DISMANTLING AND DISPOSAL

There is a pressurized refrigerant, R407C, in the refrigeration circuit and oil in the compressor. For this reason, when a unit has come to the end of its working life, it must not be dumped. It must be dist- mantled and the various parts can be recycled and/or scrapped.

Refrigerants cannot be dumped. In order to extract R407C you need:

1. A pliers like the one in Fig. 4.

WARNING: The following operations must be carried out by qualified personnel.

2.Motorcondenser

3.Pressurized vessel

Fig. 4

Proceed as follows:

•Connect the pressurized vessel to the motorcondenser, and the motorcondenser to the pliers.

•Punch a hole in the compressor’s exit tube and leave the pliers in position.

•Open both motorcondenser taps, turn it on and empty the refriger- ation circuit.

•Stop the motorcondenser and close both taps. Then close the tap on the pressurised vessel.

•Remove the pliers.

•If the pressurized vessel is full it should be given to a company that specializes in the disposal of waste fluids.

The welded joints on the compressor’s entry and exit tubes should be elimimated and lock bolts removed. Then drill a hole in the under- side of the chassis, and pour the mineral oil into a vessel which should be delivered to a company that specializes in the recycling and disposal of oil.

The remaining metal parts which contain copper, aluminium and steel can be recycled or scrapped.
