Safety Introduction Read and follow these safety instructions. Task- and equipment-specific warnings, cautions and instructions are included in equipment documentation where appropriate. Qualified Personnel Equipment owners are responsible for making sure that EFD equipment is installed, operated and serviced by qualified personnel. Qualified personnel are those employees or contractors who are trained to safely perform their assigned tasks.
Safety Fire Safety To avoid a fire or explosion, follow these instructions. • Do not smoke, weld, grind or use open flames where flammable materials are being used or stored. • Provide adequate ventilation to prevent dangerous concentrations of volatile particles or vapors. Refer to local codes or your material MSDS for guidance. • Know where emergency stop buttons, shutoff valves and fire extinguishers are located.

Getting Started Unpack the Unit / Warranty 1 • Unpack the unit. • Now is a good time to activate your Two Year Warranty. Register the warranty online at www.efd-inc.com/warranty/two. Or if you prefer, follow the instructions in the enclosed “Welcome” letter to contact your EFD representative. Install Barrel Holder 2 • Remove sleeve from barrel holder. • Insert 6 mm screw through wire adapter hose holder, then through barrel holder ❶. • Tighten screw to secure holder to dispenser cover.
Getting Started Connect Foot Pedal 4 • Connect the foot pedal to the back of the Ultra 870. Push the white tubing into the white fitting; push the black tubing into the black fitting. ! foot pedal connector Attach Syringe Barrel / Dispense Tip 5 • Attach an EFD syringe barrel filled with your fluid to the adapter assembly. • Snap the safety clip on the adapter hose closed to prevent dripping. Remember to unsnap the clip when ready to dispense.

CAUTION: Maximum Input Air Pressure 100 psi (6.9 Bar) Refer to User's Guide for instructions on proper use of this equipment prior to placing into service exhaust / vacuum foot pedal air input Air Input Port • Push one end of the 6 mm air input hose into the back of the Ultra 870. A standard air hose is provided. • Connect the other end of the air input hose to your plant air supply. Note: Clean, dry filtered factory air is required to meet warranty.
Vacuum Control Using Vacuum to Make Deposits of Watery-Thin Fluids The Ultra 870 vacuum control allows low viscosity fluids, even water, to be consistently dispensed without dripping between cycles. A vacuum is exerted above the fluid in the barrel to prevent dripping. For medium to high viscosity fluids, the vacuum should be shut off.
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.
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. 1. 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.
Initial Test Procedures Deposit size is controlled by how long you press the foot pedal, pressure and tip size. Please follow these instructions to test the Ultra 870 functions. Use the convenient Dot Standards sheet included in your dispensing kit. 1. Attach an EFD syringe barrel filled with your assembly fluid to the adapter assembly as shown. 2. Keep the vacuum shut off during initial testing. (If you are dispensing a watery fluid, see Vacuum Control, page 12). 3.

Troubleshoot If you encounter a problem that you cannot readily solve, call EFD. Trouble Possible cause and correction Inconsistent beads 1. Check dispensing tip, syringe barrel and material for possible clogging. 2. Check air pressure to be sure pressure is not varying. If needed, use the filter regulator (EFD part #2000F755). 3. Air bubbles in the material can cause inconsistency. For best results, remove all air bubbles. Material suck-back 1.
Helpful Hints Helpful Hints 1. There are three core variables to the Ultra 870 dispenser: foot pedal time, pressure and vacuum. Adjust just one of these at a time, in small increments, to achieve the correct deposit. 2. Another variable is tip size. Choose the right tip for the deposit type. Remember, smaller tips require more pressure and more time pressing the foot pedal. Try different tips without changing the time or pressure settings and observe the results. 3.
