Troubleshooting
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.
Problem
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.
