IMPORTANT
Regardless of the fluid viscosity, using the correct EFD piston will give you better results.
White SmoothFlow
™
piston for most fluids, blue LV Barrier
™
for watery-thin fluids and
orange flat wall piston for thick, stringy fluids. See pages 24 - 25 for a complete description
of how EFD pistons work and the benefits they can bring to your operation.

If you choose
not
to use the piston, please follow these instructions
carefully:
1.
While holding the barrel upright in one hand, twist on an orange
tip cap. Using the small funnel, fill about 2/3 full with your fluid.
2.
Open the safety clip and attach the barrel to the 10cc adapter.
3.
Close the safety clip as tight as possible.
4.
Increase vacuum by turning vacuum control knob counter-
clockwise and set to 1.5 on the vacuum pressure gauge.
5.
Then, without tipping the barrel upside down, remove the tip
cap and attach the 25 gage (red) tip.
6.
Open the safety clip. Your material may begin to bubble.
Reduce vacuum by turning vacuum control knob clockwise.
7.
If a drop begins to form at the end of the tip, slowly turn the
vacuum control knob counterclockwise to stop the drop from
growing. Wipe the tip and adjust vacuum as necessary.
Now the fluid is in proper balance. It does not bubble or drip.
Repeat tests as before, keeping the air pressure low and adjust-
ing the time for different deposit sizes. Contact EFD if you have
any questions.

Do not tip the barrel upside down
or lay flat. This will cause the
liquid to run into the dispenser.
When changing tips
or attaching a tip cap,
snap the safety clip
completely closed to
prevent any dripping
or bubbling.
Three things to remember
If you do not use the piston
when dispensing thin fluids:
Use an EFD filter trap
(#1000FLT-Y). This
filter trap will impede
the flow should the
low viscosity liquid be
sucked back towards
the dispenser.
