Operation
WARNING:
Allow only qualified personnel to perform the following tasks.
Observe and follow the safety instructions in this document and all other
related documentation.
Important When Using Polyurethane Application
Materials (PUR)
It is imperative that the following guidelines are followed when processing
polyurethane application materials (PUR):
S
Wear respiratory protection when the maximum permissible
concentration of hazardous substances is exceeded.
S
Before prolonged standstill of the application system, purge with a
suitable cleaning agent. Use only a cleaning agent recommended by the
material manufacturer.
S
Close open material connections airtight.
When the system is to cease operation for only a short time, it suffices to coat
the application slot generously with grease.
CAUTION:
Use only special high‐temperature grease. Refer to page
Processing Materials
! Any other grease may cause the PUR material to
cross‐link.
Triggering Solenoid Valves
CAUTION:
Trigger the solenoid valves only when the applicator is heated to
operating temperature! Seals in the application control module and the
retrosuction control module can become damaged if the material is too cold.
Setting Temperature
NOTE:
When setting the temperature, the temperature prescribed by the
material manufacturer is decisive. The maximum operating temperature of
the product described here may not be exceeded.
The applicator temperature required is set on the melter (maximum 200
°
C /
392
°
F).
Nordson will grant no warranty and assume no liability for damage resulting
from incorrect temperature settings.
