Ultra Dispensing System - EFD 800 Operating Manual

If you dispense thick fluids, several problems may
occur. First, the repetitive air cycles can bore tunnels
through non-leveling fluids, causing spitting and
inconsistent deposits. Second, thick fluids contain
trapped air that leads to drooling and oozing.
These problems are eliminated by using the SmoothFlow
piston. That's because the white pistons prevent
tunneling by providing a barrier to the pulsed-air
cycles, and prevent oozing by responding to the
pressure of trapped air with a slight suck-back
movement after the dispense cycle.
The white piston is used for most fluids.
However, if you are applying RTV silicone and find
that the piston bounces and causes stringing, switch
to the orange, flat wall piston.
The SmoothFlow ™ pistons make barrel filling easier,
too. As you load the fluid in, air is trapped in the
bottom and throughout the fluid. Simply insert a
SmoothFlow ™ piston and gently press down on the
fluid as far as possible. This action forces out most
of the air and results in consistent deposits.
