remove the voltage selector from the cartridge,
rotate it and position the correct voltage to show
through the cartridge window. Replace the

Setup for Testing

You are now ready to test the dispenser using the prefilled barrel
of blue, nontoxic test material.
Begin with the following settings:
Thick fluid (blue) Thin fluid (clear)
Air gauge 10 psi (0.7 bar) 5 psi (0.4 bar)
Dispense tip 18 gage (green) 25 gage (red)
Vacuum control Off On (see page 9)
Press the power switch on. It will light green.
Holding the barrel as shown, rest the tip on a piece of paper. Press
the foot pedal until the tip fills and some fluid is pushed out onto the
paper. (Repeat this whenever you change to a new tip.)
Use the Dot Test Sheet supplied, and press the foot pedal to make
a dot or stripe. Make several more deposits, carefully applying the
tip at the angle shown and removing the tip as shown.
Remember - always bring the tip in contact with the work surface at
theillustratedangle. Afterthe tip is inposition,pressthefoot pedal.
A continuous flow of material will occur as long as the foot pedal is
pressed.
Trydifferentpressuresettings. Continuetoexperimentbyreplacing
the green tip with the blue (22 gage) tapered tip included in the Dot
TestKit. Notethe effects of airpressureand tip sizeonthe deposit.
Adjusting the Deposit Amount
The deposit size is determined by the tip diameter, the output air
pressure setting and the length of time the foot pedal is pressed.
Toincreasethedepositsize,slightlyincreaseoutputairpressure,or
increase tip size, or both. To decrease the deposit amount, use a
smaller tip size, or lower the air pressure.
Testing the Dispenser
Correct angle for making deposits.
Remember-alwaysbringthetipin
contact with the work surface at
theillustratedangle. Afterthetipis
in position, press the foot pedal.
Release pedal and remove tip by
lifting straight up.

Using the Vacuum Control
The vacuum control allows low viscosity fluids,
even water, to be consistently dispensed without
dripping between cycles. The vacuum exerts a
negative pressure on the fluid in the barrel and
prevents dripping.
Forthesetests,youwillusethetestbarrelwiththe
clear fluid.
1. While holding the barrel upright in one hand,
remove the orange end cap and insert the
white SmoothFlow™piston. Carefully press
the piston down until it contacts the fluid.

but not into the fluid, since this will force the
fluid up along the sides of the piston.
2. Attach the barrel to the yellow adapter head.
Snap the safety clip tightly closed to prevent
anydrippingorbubbling. Remove thetipcap
and attach the 25 gage (red) tip.
3. Set air pressure at 5 psi (0.4 bar).
4. With the barrel pointing downward over a
container, press the foot pedal to fill the tip.

5. If a drop begins to form at the end of the tip,

necessary.

Regardless of the viscosity of the fluid you use,

Ifyouchoosenottousethepiston,pleasereadthe
following points. rate by increasing the air pres-
sure output (higher flow) or decreasing the air
pressure output.
Do not tip the barrel
upside down or lay flat.
This will cause the fluid
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 fluid be sucked
back towards the dispenser.

Advanced Dispensing System
TM
If you dispense thick fluids, several problems may
occur. First,therepetitiveaircyclescanboretunnels
through non-leveling fluids, causing spitting and
inconsistent deposits. Second, thick fluids contain
trapped air that leads to drooling and oozing.
TheseproblemsareeliminatedbyusingtheSmoothFlow™
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
thatthepistonbouncesandcausesstringing,switch
to the orange, flat wall piston.
TheSmoothFlow™pistonsmakebarrelfillingeasier,
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.

Ifyouuselowtomediumviscosityfluids,thewhite
SmoothFlow™piston has several advantages.
First, vacuum adjustment is much less sensitive.
Second, the piston prevents fumes from the fluid
beingexhaustedintotheworkenvironment. Third,
the piston prevents fluid backflow into the dis-
penser if the barrel is inadvertently turned upside
down. Fourth,usingthepiston makesiteasyand
safe to change tips without dripping.

Caution: Do not completely fill barrels. The optimum fill is a maxi-

2. If you receive frozen epoxies or other fluids in medical type
syringes with a manual plunger, ask your fluid packager to use
EFD industrial grade barrels, or request our luer-to-luer fitting

Suggestions & Reminders
1. Always use an EFD piston to make your barrel loading,
dispensing and handling cleaner, safer and more accurate.
Caution: Ifyoudispensewatery-thinfluidsandchoosenottouse

2. Always use new barrels and tips. Carefully dispose of after
use. This procedure ensures maximum cleanliness, pre-
vents contamination and provides proper safety.
3. Donotcompletelyfillthebarrel. Formostfluids,optimumfill

4. Use the EFD #DS1200 DispenStand™to help organize
bench space. Adapter hose support keeps hose off of the
work area. See illustration.
5. Depending on the type of work you are doing, it may be
easier to bring the work to the barrel. Mount the barrel on a
stand such as the EFD #7300A.
6. To ensure smooth fluid flow and to make consistent depos-
its, always have the tip at about a 45°angle to the work
surface.
