Trouble
Solution
No fluid being
dispensed
Check the power supply connection and DC power supply to the
unit.
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 turned off (fully
counterclockwise)
If dispensing high viscosity materials, try increasing output air
pressure slightly.
Vacuum level is set to high.
Barrel adapter safety clip may be clamped shut.
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.
Vacuum level is set to high.
Barrel adapter safety clip may be clamped shut.
Material suck-back
Always use an appropriate piston to prevent material from being
drawn back into the dispenser.
