Bleeding the system
Before conducting all maintenance and repair work on adhesive application systems, the system must be
"completely depressurized".
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.
