Section Repair
External Cleaning
External cleaning prevents impurities created during production from
causing the melter to malfunction.
CAUTION: Observe the unit’s Degree of Protection when cleaning (Refer
to section Technical Data).
CAUTION: Do not damage or remove safety labels. Damaged or removed
safety labels must be replaced by new ones.
Remove material residue only with a cleaning agent recommended by the
material supplier. Heat with an air heater if necessary.
Remove dust, flakes etc. with a vacuum cleaner or a soft cloth.
Nordson recommends the orange cleaning agent P/N 771 192 (12 spray
bottles, 0.5 liter each).
Control Panel
CAUTION: Set Screen cleaning (V20 in section Operation). This ensures
that no functions are unintentionally triggered by touching the screen.
Clean the insides of the plastic frame on the control panel front regularly
with a damp, soft cloth. Use caution to ensure that the surface is not
scratched or scoured, particularly when removing hard residue and abrasive
dust. Do not allow solvents to come into contact with the panel front;
solvents could corrode the plastic frame.
