DISMANTLING AND DISPOSAL

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
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.
