2.2 Environnement of the machine
The machine must be installed on the stable bench , can supported the weight of the apparatus ( see
characteristics)
It is necessary to respect a minimum environment volume to ensure proper operation and longevity
.
Allow minimum space : 25cm behind and 40 cm on the sides , 100 cm above to ensure adequate
ventilation space.
Do not install the machine near the heating source ( radiator , stove , oven or apparatusl sending hot
air , …), or behing a window receiving the sun
