 The power supply cable must be in perfect conditions and must not show any damage. Do not
bend the cable. Do not place it over hot surfaces or hang it and protect it from oil. Never
connect the cable if you have wet hands.
 When you connect the unit, check that the voltage and the frequency of power supplies match
with the value indicated on the label place on the back of DMA-80 EVO.
 Never touch parts with live wires. This may cause an electric shock, which can result in serious
injuries or even death.
 The exhaust gases may contain high Hg concentrations, depending on the working
conditions. A proper treatment of the gases is necessary.
 Should a neon tube or a low pressure lamp break, this could increase the Hg mercury in the
DMA-80 EVO. The area must be properly aired.
1.9 Cleaning instructions
 Before any maintenance on the unit and before cleaning it, disconnect the power supply cable.
 Keep the air inlet and outlet openings always free from pollution.
 You can clean the surfaces of the unit with a wet cloth, warm water and a mild household
