Introduction
This section contains information about how to perform initial setup of the VC350A Flexoseal
®
system.
Glue Delivery System
To set up the glue delivery system, follow these steps:
1. Stop the parent machine.
2. With the supply hose removed from the glue valve, run adhesive through the system until no air is present
in the glue line.
Note! A smooth flow of glue should exit the shutoff valve for one minute.
3. To remove any trapped air in the fluid regulator, turn the “T” handle completely clockwise.
4. Turn the “T” handle completely counterclockwise.
5. Repeat steps 3 and 4 twice.
6. Set the fluid regulator to 10 psi (1.7 bar) for contact applications or to 20 psi (2.4 bar) for non-contact
applications.
7. Install the glue hose with shutoff valve onto the glue valve.
