Before conducting all maintenance and repair work on adhesive application systems, the system
must be "completely depressurised".
Through the pressure relief valve, the glue pressure in the system is reduced after the air pressure
has been disconnected.
When working on the adhesive application system, follow the safety regulations for handling hot
media.
The following steps have to be conducted:
•
Set the pump inlet pressure to 0 bar. Unscrew the nozzle on the application head.
•
Position the collecting container under the application head to avoid equipment
contamination. Press the manual release at the solenoid valve until no more adhesive
emerges from the application head.
•
Release residual pressure in the manifold block by removing the tank filter cover and opening
the drain screw.
