5. Place the nozzle in a container of TypeR fluid. Use a controlled heating
device (such as a small, deep fat fryer or thermostatically‐controlled hot
plate) to heat the TypeR fluid above the hot melt adhesive material
melting temperature.
NOTE: Another method for cleaning nozzles is to place the parts in an
ultrasonic cleaner filled with TypeR fluid.
NOTE: Pin‐type probes are not for use on zero cavity, reduced cavity, or
swirl modules. Review the instruction sheet received with zero cavity and
reduced cavity modules for specific nozzle cleaning procedures. Call
your Nordson representative if you have any questions regarding the
correct cleaning procedure for your modules and nozzles.
