10. Place a pan or other suitable waste container under the manifold
drain valve. Using a screwdriver, open the drain valve in the
applicator manifold.
NOTE: Failure to use a screwdriver may turn the valve body resulting in
equipment damage and possible discharge of molten material.
11. Gradually pressurize the pump and allow adhesive to flow in order to
remove air trapped in filter.
12. Using a screwdriver, close the drain valve after all air within the filter
is removed.
13. Allow material to exit the gun(s) until all trapped air and impurities are
flushed out of the system.

WARNING: Burn hazard. Trapped air may still be in the
0
hose(s) and gun(s) causing the spitting of air and molten
material.
NOTE: It may be necessary to increase the pump air pressure to
produce flow in the system.
NOTE: The pump will transfer adhesive material from the tank to the
manifold, hose(s) and gun(s). The system is full when the pump stalls
or slows noticeably.
14. When material flows free of trapped air and contaminants, stop
triggering the gun(s).
