[. . . ] Ultra® 870 Dispenser User's Guide Electronic pdf files of EFD manuals are also available at www. efd-inc. com/manuals. html Ultra 870 ® A NORDSON COMPANY Introduction Welcome to the Ultra 870 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. [. . . ] 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. The SmoothFlow piston eliminates these problems. It prevents tunneling by providing a barrier to the pulsed-air cycles. And it prevents oozing by responding to the pressure of trapped air with a slight suck-back movement after the dispense cycle. caulking gun 2/3 maximum fill 13 Syringe Barrel Loaders Barrel Loading Alternatives EFD offers productive alternatives to traditional syringe 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. 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 syringe barrel (with a piston installed) 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. For fast, accurate volumetric filling, the 8000BF Barrel Filling Station can be used with any pressure reservoir or cartridge. Recommended for high production barrel filling. If you receive frozen epoxies or other fluids in medical type syringes with a manual plunger, request the EFD luer-to-luer fitting #2160 to transfer the material. Please contact an EFD Fluid Application Specialist for additional assistance.

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-thanneeded pressure setting. [. . . ]
