If you encounter a problem that you cannot readily solve, call EFD.
Trouble
Possible cause and correction
No power
Be sure that there is power at the wall receptacle. Otherwise, replace fuse
(specify EFD part #7111) to power supply.
Inconsistent dots
1. Check dispensing tip, syringe barrel and material for possible clogging.
2. Check dispenser air pressure display to be sure air 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.
Timer seems
Check to be sure you are not in Steady mode.
Note: The EFD timer is very reliable. Any failure will be total, so that no
inconsistency is possible. Most questions regarding the timer are resolved by
simply turning Steady mode off.
Material suck-back
1. Use a SmoothFlow piston or LV Barrier to prevent material being drawn into
the dispenser.
2. Another option is to order the filter trap accessory, which prevents fluid from
leaking into the dispenser. Order EFD part #1000FLT-Y.
3. If suck-back occurs, attach an empty barrel, put in Steady mode, place the
barrel in a cup, then press the foot pedal to expel the fluid.
4. If the problem cannot be corrected, contact an EFD Fluid Application Specialist
for assistance.
Dispensers can be returned to EFD for repair.
Voltage initiate
Check to see that the voltage is between 5 and 24 VDC and the current does
does not function.
