Helpful Hints

1. There are three core variables to the Ultra 870 dispenser: foot pedal time, pressure and vacuum.

Adjust just one of these at a time, in small increments, to achieve the correct deposit.

2. Another variable is tip size. Choose the right tip for the deposit type. Remember, smaller tips require

more pressure and more time pressing the foot pedal. Try different tips without changing the time or

pressure settings and observe the results.

3. Tapered tips reduce the amount of air pressure needed to dispense thick materials. They also help

prevent drooling at the end of a dispense cycle.

4. To ensure smooth fluid flow and to make consistent deposits, keep the dispense tip at a 45° angle

to the work surface.

5. Use EFD SmoothFlow pistons to make barrel loading, dispensing and handling cleaner, safer and

more accurate. Caution: If you dispense watery fluids and choose not to use EFD pistons, do not

increase vacuum pressure rapidly and do not tip the barrel. Vacuum may pull fluid into the adapter

hose, or if the syringe barrel is tipped, fluid may flow back into the dispenser.

6. Always use new EFD syringe barrels and tips. Carefully dispose of after use. This procedure ensures

maximum cleanliness, prevents contamination and provides proper safety.

7. Do not completely fill the syringe barrel. For most fluids, optimum fill is a maximum 2/3 of the barrel

capacity. For cyanoacrylates or watery fluids, optimum fill is 1/2 of the barrel capacity.

Suggestions on Settings

1. To reduce air pressure, turn the knob counterclockwise until the display reads at a lower-than-

needed pressure setting. Then turn clockwise to increase pressure until you reach the correct

setting.

2. Avoid high pressure settings with very small deposit settings. The ideal setup matches air pressure

and tip size to create a “workable” flow rate – no splashing, but not too slow either.

3. With any fluid, always give the air pressure time to do its job. Moderate time and pressure provides

the best results since dispensing pressure remains at its peak for a longer period of time.
