[. . . ] Ultra® 1400 Series Dispenser User's Guide Electronic pdf files of EFD manuals are also available at www. efd-inc. com/manuals. html Ultra 1400 Ultra 1415 ® A NORDSON COMPANY Introduction Welcome to the Ultra 1400 Series User's Guide, designed to help you maximize the usefulness of your new dispenser. Please spend a few minutes to become familiar with the controls and features. Follow our recommended testing procedures. Review the helpful information we have included, which is based on more than 30 years of industrial dispensing experience. [. . . ] Wipe the tip and adjust vacuum as necessary. Press the Steady button again to return to Timed mode. 9. 10. Rest the tip on the Dot Standards sheet. Increase or decrease by adjusting pressure or time as needed. Helpful Hint For low viscosity fluids, use an EFD filter trap (#1000FLT-Y). This filter trap will impede the flow should the liquid be sucked back towards the dispenser. 14 Filling the Syringe Barrel Syringe Barrel Filling Techniques Caution: Do not completely fill syringe barrels. The optimum fill is a maximum 2/3 of the barrel capacity and 1/2 of the barrel capacity when using the EFD blue LV Barrier piston. For best results, we strongly recommend that you use a piston as part of your dispensing system. The white EFD SmoothFlow piston is appropriate for most fluids and has several advantages. · · First, vacuum adjustment is 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 syringe barrel is inadvertently turned upside down. Fourth, the piston makes it easy and safe to change tips without dripping. Remember For best results, EFD strongly recommends the use of a piston as part of your dispensing system. No air gap when using the SmoothFlow piston. SmoothFlow piston prevents fluid backflow. If you choose to not use a piston when dispensing thin fluids, remember these important points. Open Do not tip the barrel upside down or lay flat. This will cause the liquid to run into the dispenser. · Closed When changing tips or attaching a tip cap, snap the safety clip completely closed to prevent any dripping or bubbling. · For watery solvents and cyanoacrylates, request the blue EFD LV Barrier piston, available in 3cc and 10cc sizes. If you are dispensing an RTV silicone and find that the piston bounces and causes stringing, request the EFD orange, flat wall piston. Filling procedure for pourable low and medium viscosity fluids If the fluid you are dispensing is pourable, take the syringe barrel, twist on an orange tip cap and pour your fluid in. Insert a white SmoothFlow piston and carefully press down until it contacts the fluid. The syringe barrel is now ready for use. 2/3 maximum fill SmoothFlow piston Filling procedure for thick fluids If your fluid is thick or non-leveling, you can spoon it into the syringe barrel with a spatula. Or, if the fluid comes packed in a 1/10 gallon (300 ml) cartridge, try loading the barrel with a caulking gun. Then, press the SmoothFlow piston to move the fluid to the bottom of the syringe barrel and remove trapped air. Trapped air in thick fluids can lead to drooling and oozing. Also, repetitive air cycles can bore tunnels through non-leveling fluids, causing spitting and inconsistent deposits. [. . . ] 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. Longer dispense time settings generally provide the highest accuracy. However, in the interest of costeffective production, do not use excessively long dispense time settings. [. . . ]
