Setup for Testing

Power switch ❶ should be off. The amount of material dispensed each cycle depends on the

combination of air pressure, viscosity of material, dispensing tip size and the length of time the foot pedal is pressed.

The first step is to remove the tip cap from the prefilled barrel of blue test material (twist and pull). Replace it with an 18 gage (green) tapered dispensing tip. Press the tip on and twist clockwise to lock.

Pull out air pressure regulator knob ❷ until it "clicks" into the unlocked position. Turn clockwise to adjust the air pressure to 10 psi (0.7 bar) for the initial tests.

Always set the pressure desired by turning the air regulator knob

❷ clockwise. To reduce the pressure, turn the knob counterclock-

wise until the air gauge ❸ reads a lower pressure than desired. Then increase and stop at desired pressure. Push knob in to lock.

Be sure barrel vacuum control ❹ is turned off (turn clockwise) for initial tests.

Press power switch ❶ to turn on the dispenser. It will light green. Please continue to page 8 for test procedures.

Testing the Dispenser

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 the illustrated angle. After the tip is in position, press the foot pedal. A continuous flow of material will occur as long as the foot pedal is pressed.

Try different pressure settings. Continue to experiment by replacing the green tip with the blue (22 gage) tapered tip included in the Dot Test Kit. Note the effects of air pressure and tip size on the 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.

To increase the deposit size, slightly increase output air pressure, or increase tip size, or both. To decrease the deposit amount, use a smaller tip size, or lower the air pressure.

Correct angle for making deposits.

Remember - always bring the tip in contact with the work surface at the illustrated angle. After the tip is 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.

For these tests, you will use the test barrel with the 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.

Be sure to push it far enough to remove all air, 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 any dripping or bubbling. Remove the tip cap 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, slowly turn the vacuum control knob counterclockwise to stop the drop from growing. Wipe the tip and slowly adjust vacuum as necessary.

6. Take the barrel and place the tip on the Dot Test Sheet. Press the foot pedal and release. Check the deposit. You control the fluid flow

Regardless of the viscosity of the fluid you use, you should try using the SmoothFlow™ piston (see pages 10-11).

If you choose not to use the piston, please read the following points. rate by increasing the air pressure output (higher flow) or decreasing the air pressure output.

Three things to remember

If you do not use the piston

when dispensing thin fluids:

Do not tip the barrel upside down or lay flat. This will cause the fluid to run into the dispenser.

Open

Closed

When changing tips or attaching a tip cap, snap the safety clip completely closed to prevent any dripping or bubbling.

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

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.

No drip or ooze.

If you use low to medium viscosity fluids, the white SmoothFlow™ piston has several advantages.

First, vacuum adjustment is much less sensitive. Second, the piston prevents fumes from the fluid being exhausted into the work environment. Third, the piston prevents fluid backflow into the dispenser if the barrel is inadvertently turned upside down. Fourth, using the piston makes it easy and safe to change tips without dripping.

Note: If you use watery-thin fluids such as solvents, cyanoacrylates and anaerobics, specify the ULTRA System™ with the blue LV Barrier™. Available in 3cc and 10cc sizes.

Note: If you choose not to use the piston,

please refer to page 9 for instructions.

Loading the Barrel Reservoirs

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

mum 2/3 of the barrel capacity and 1/2 of the barrel capacity when using the LV Barrier™.

If the fluid you are dispensing is pourable, take the barrel, twist on a tip cap and pour your fluid in. If appropriate, insert the SmoothFlow piston (see pages 10-11). Carefully press the piston down until it contacts the fluid. The barrel is now ready for use.

If you are dispensing watery solvents, cyanoacrylates or anaerobics, use the LV Barrier™. Place barrier in the top of the barrel reservoir. Allow air between barrier and fluid. Do not contact the barrier to the fluid.

If your fluid is thick or non-leveling, you can spoon it into the barrel with a spatula Or, if the fluid comes packed in a 1/10 gallon cartridge, try loading the barrel with a caulking gun. Then press in the SmoothFlow™ piston to move the fluid to the bottom of the barrel and to remove trapped air.

Filling the cartridge for the barrel loader.

EFD offers productive alternatives to traditional barrel-loading methods. Here are a few suggestions that can help keep your work area clean, save time and reduce the chance of entrapped air in the fluid.

1. You could use the EFD #920BL barrel loader. Pack the fluid into the 12 ounce cartridge as shown. Then place the pre-filled cartridge into the barrel loader. Using air pressure, the barrel loader fills the barrel (with piston) from the bottom up.

If the fluid comes packed in a 1/10 gallon (300 ml.) caulking type cartridge, use the EFD #940BL barrel loader.

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 #2160 to transfer the material.

Please call an EFD Fluid Application Specialist for additional assistance.

Suggestions & Reminders

1. Always use an EFD piston to make your barrel loading, dispensing and handling cleaner, safer and more accurate.

Caution: If you dispense watery-thin fluids and choose not to use SmoothFlow™ pistons – do not increase vacuum pressure rapidly and do not tip the barrel. Vacuum may pull liquid into the air hose; or when tipped, liquid may flow back into the dispenser.

2. Always use new barrels and tips. Carefully dispose of after use. This procedure ensures maximum cleanliness, prevents contamination and provides proper safety.

3. Do not completely fill the barrel. For most fluids, optimum fill is a maximum 2/3 of the barrel capacity. For cyanoacrylates or watery-thin fluids, optimum fill is 1/2 of the barrel capacity.

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 deposits, always have the tip at about a 45° angle to the work surface.
