[. . . ] Operating Guide 1000 Series Dispensers 1000XL · 1000D ® In the US: 800-556-3484 A NORDSON COMPANY In the UK: 0800 585733 In Mexico: 001-800-556-3484 Introduction The 1000 Series dispensers provide years of trouble-free, productive service. This Operating Guide will help you maximize the usefulness of your new dispenser. Please spend a few minutes to become familiar with the controls and features of your new dispenser. Follow our recommended testing procedures. [. . . ] The white piston is used for most fluids. However, if you are applying RTV silicone and find that the piston bounces and causes stringing, switch to the orange, flat wall piston. The SmoothFlowTM pistons make barrel filling easier, too. As you load the fluid in, air is trapped in the bottom and throughout the fluid. Simply insert a SmoothFlowTM piston and gently press down on the fluid as far as possible. This action forces out most of the air and results in consistent deposits. For Thick Fluids Air Pressure ON Air Pressure OFF No drip or ooze. If you use low to medium viscosity fluids, the white SmoothFlowTM piston has several advantages. First, vacuum adjustment is much 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 barrel is inadvertently turned upside down. Fourth, using the piston makes it easy and safe to change tips without dripping. Note: If you use watery-thin fluids such as solvents, cyanoacrylates and anaerobics, specify the ULTRA . SystemTM with the blue LV BarrierTM Available only in 10cc size. For Thin Fluids SmoothFlowTM piston prevents fluid backflow. For Watery-thin Fluids Blue LV BarrierTM for improved control of very low viscosity fluids. Fumes cannot escape. Note: If you choose not to use the piston, please refer to page 19 for instructions. How to Use the Vacuum Control The vacuum control allows low viscosity fluids, even water, to be consistently dispensed without dripping between cycles. The vacuum exerts a negative pressure on the fluid in the barrel and prevents dripping. For these tests, you will use the test barrel with the clear fluid. While holding the barrel upright in one hand, remove the orange end cap and insert the white SmoothFlowTM piston. Carefully press the piston down to contact the liquid. Be sure to push it far enough to remove all air, but not into the fluid, since this will force the fluid up along the sides of the piston. Snap the safety clip tightly closed to prevent any dripping or bubbling. Remove the tip cap and attach the 25 gage (red) tip. Set air pressure at 5 psi and timer to #5, then turn on timer bypass. With the barrel pointing downward over a container, press the foot pedal to fill the tip. Turn off the timer bypass switch (yellow light out). [. . . ] For slow filling, a longer time range will provide the time that's needed for flow control.

Always use an EFD SmoothFlowTM piston or LV BarrierTM to make barrel loading, dispensing and handling cleaner, safer and more accurate. Caution (1000XL only): If you dispense pourable fluids and choose not to use SmoothFlowTM pistons, do not increase vacuum pressure rapidly and do not tip the barrel. Vacuum may pull liquid into the air hose; or when tipped, liquid may flow back into the dispenser. [. . . ]
