Helpful Hints / Suggestions on Settings
Helpful Hints
• There are three core variables to the Performus dispenser: dispense time, pressure, and
vacuum. Adjust just one of these at a time, in small increments, to achieve the correct
deposit.
• Another variable is tip size. Choose the right tip for the deposit type. Remember, smaller
tips require more pressure and more dispense time. Try different tips without changing
the dispense time or pressure settings and observe the results.
• 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.
• To ensure smooth fluid flow and to make consistent deposits, keep the dispense tip at a
45° angle to the work surface.
• Use EFD SmoothFlow pistons to make barrel loading, dispensing, and handling cleaner,
safer, and more accurate.
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.
CAUTION
• Always use new EFD syringe barrels and tips. Carefully dispose of after use. This
practice ensures maximum cleanliness, prevents contamination, and provides proper
safety.
• 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
• 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.
• 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.
• 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.
