5. Maintenance
Warning!
Electric shock hazard!
• Switch off the power supply unit and disconnect the supply voltage
before carrying out any maintenance or repair work.
• The bars passively absorb energy from the moving substrate web. The
high voltage cable must be plugged in or grounded to the power supply.
If the high voltage cable is disconnected, the plug is live (high voltage)
and applies with full power on the plug; this may cause a spark dis-
charge and may lead to a risk of injury. Disconnected high voltage plugs
are not permitted or have to be grounded.
• The machine which has the units fitted must not be in operation.
• Repairs and maintenance work must be carried out by qualified
electricians.
5.1 Cleaning the nozzle inserts
To ensure the trouble-free function of the ion blower heads, the surface
from which the emission tips and the compressed air exit must be clean
and dry at all times. Dirty blower heads must be cleaned with a suitable
solvent (cleaning gasoline) and a brush with soft plactic bristles. To pre-
vent the air exit holes from clogging up with dirt during cleaning, the com-
pressed air (0.3...0.5 bar) must be switched on during cleaning.
Warning!
Risk of deflagration!
Allow the solvent to evaporate completely before restarting the unit.
Caution!
Do not damage the emission tips when cleaning.
5.2 Filter / Filter change
Inspect and, if necessary, exchange the filter for dirt deposits at regular
intervals.
Hold filter casing tight, loosen and pull off the union nut.
Exchange the filter and turn back in reverse order. Finally, check the
proper assembly.
