Troubleshooting Guide
An EFD Customer Service or Technical Services representative is always available to assist you with
any question you may have about your Performus Dispensing System. Please feel free to call or
email us at the addresses on the back cover of this User’s Guide.
Trouble Solution
No power Check the power supply connection and DC power supply to the unit.
No fluid being
dispensed
Check the main air supply and primary regulator.
Check to make sure that the main air supply is connected to the
back of the unit and has not come loose.
Check to make sure that the regulator is not turned off (fully
counterclockwise).
If dispensing thicker materials, try increasing output air pressure
slightly.
Inconsistent
dispense output
Check the dispensing tip, barrel and material for possible
contamination or clogs.
Note: Dispensing System Components are disposable. Do not
attempt to reuse.
Check for air supply pressure fluctuation.
Air bubbles in the fluid path and entrapped air within the fluid may
cause inconsistency. For best dispensing results, remove all
entrapped air before dispensing.
Material suck-back
Always use an appropriate piston to prevent material from being
drawn back into the dispenser. For thick to medium viscosity fluids
use EFD SmoothFlow pistons. For thin, low viscosity fluids, use
EFD LV Barrier pistons.
Another option is to order optional barrel adapters with filter traps.
Part numbers for all adapters are listed on the components poster
included with your Performus system.
