[. . . ] Qualified personnel are those employees or contractors who are trained to safely perform their assigned tasks. They are familiar with all relevant safety rules and regulations, and are physically capable of performing their assigned tasks. Intended Use Use of EFD equipment in ways other than those described in the documentation supplied with the equipment may result in injury to persons or damage to property. Some examples of unintended use of equipment include · · · Using incompatible materials Making unauthorized modifications Removing or bypassing safety guards or interlocks · · · Using incompatible or damaged parts Using unapproved auxiliary equipment Operating equipment in excess of maximum ratings Regulations and Approvals Make sure all equipment is rated and approved for the environment in which it is used. Any approvals obtained for EFD equipment will be voided if instructions for installation, operation and service are not followed. Personal Safety To prevent injury follow these instructions. [. . . ] A vacuum is exerted above the fluid in the barrel to prevent dripping. If you are dispensing watery solvents, cyanoacrylates or anaerobics, request the blue LV BarrierTM piston and follow these steps to fill the syringe barrel and set the vacuum control. Twist an orange tip cap onto an empty syringe barrel and pour your fluid in. 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. Also, repetitive air cycles can bore tunnels through non-leveling fluids, causing spitting and inconsistent deposits. 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. 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. 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.

Use the convenient Dot Standards sheet included in your dispensing kit. Attach an EFD syringe barrel filled with your assembly fluid to the adapter assembly as shown. To purge the dispense tip, pull the air pressure regulator knob out until it clicks into the unlocked position. Slowly, turn the pressure knob clockwise until your fluid begins to dispense out of the tip in a controlled flow (not too fast, not too slow). [. . . ] For dispensing cyanoacrylates, order the regulator with a coalescing filter that removes liquid aerosols from the air supply (EFD part #2000F756). exhaust / vacuum Cleanroom filter muffler Attaches to the Ultra 870 exhaust port and filters output air to meet Fed 209-B (0. 5 micron particulates). 19 EFD Two Year Limited Warranty All components of EFD dispensers are warranted to the original end user for two years from date of purchase. Within the period of this warranty, EFD will repair or replace free of charge any defective component on return of the part, or the complete dispenser, prepaid to the factory.
