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 771192 (12 spray
bottles, 0.5 l each).
Visual Inspection for External Damage
WARNING: When damaged parts pose a risk to the operational safety of
the melter and/or safety of personnel, switch off the melter and have the
damaged parts replaced by qualified personnel. Use only original Nordson
spare parts.
Changing Type of Material
NOTE: The overtemperature thermostats must be adjusted (replaced) to
accommodate the maximum temperature of the material used. The
shutdown value of the thermostat may not exceed the maximum operating
temperature of the melter!
1. Run the melter until empty.
2. Determine whether the new material may be mixed with the old material.
S May be mixed: Remaining old material can be flushed out using the new
material.
S May not be mixed: Thoroughly purge the unit with a cleaning agent
recommended by the material supplier. Refer to Controls Pump Speed
and Purge Mode / Purge in the section Operation.
NOTE: Properly dispose of the old material according to local regulations.
