PRESERVE THE ENVIRONMENT!
We care about protecting the environment. When the unit is
dismantled it is important to adhere scrupulously to the following
procedures.
The unit should only be dismantled by a firm authorized
for the disposal of scrap machinery.
The unit as a whole is composed of materials considered
as secondary raw materials and the following conditions
must be observed:
If the system has antifreeze as an additive,it must not be
just dumped,because it causes pollution.It should be
collected and suitably disposed of.
The electronic components(electrolytic condensers)
should be considered special waste,and as such they
should be delivered to a firm authorised to collect them.
The expanded polyurethane rubber insulation on the
pipes and the expanded polyethylene mesh,the xpanded
polyurethane and sound-absorbent spong lining the
bodywork must be removed and processed as urban
refuse.
