External Cleaning
External cleaning prevents impurities created during production from causing
the melter to malfunction.
CAUTION: Observe the melter'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 manufacturer. Heat with an air heater if necessary.
Remove dust, flakes etc. with a vacuum cleaner or a soft cloth.
Nordson recommends the cleaning agent P/N 771192 - CLEANER C,
12 spray bottles, 0.5 liter each. Observe material safety data sheet!
Control Panel
CAUTION: Set Screen cleaning. 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 control panel front; solvents
could corrode the plastic frame.
