TROUBLESHOOTING
Flowrate too low:
Follow the instructions to increase the flowrate in chapter 'Calibration/ Flowrate
Adjustment'. Ensure that the operating pressure (at the nozzle/ hose connection) is at least 1,5 bar.
No dispensing:
Ensure that the operating pressure (at the nozzle/hose connection) is at least 1,5 bar.
ln case of unreleased pressure in the spout -caused by improper operation'l - first try to release the
pressure by pushing the EW 22 test adapter onto the spout until stop. If this does not help, remove
the scuffguard, remove the guard and loosen the spout screw with EW SK 3 (hex key, 3 mm) until
liquid cornes out, see pictures below. Attention, splashes possible - wear safety glasses. Reassembly
in reverse order.
Spout untight:
Check for mechanical damage, in this case substitute the spout. Also check if AdBlue
®
has crystallised in the spout tip. ln this case soak the nozzle spout in a bucket of warm water. This helps
to dissolve the crystals.
No automatic shut-off:
Push EW 22 test adapter over the nozzle spout to override the misfilling
prevention, check if the flow rate is at minimum 3 I/min when the lever is fully pulled and afterwards
(
in the upper latched position. If necessary, follow the instructions to increase the flowrate on page 12.
Premature shut-off:
Check if AdBlue
®
has crystallized in the spout tip. ln this case soak the nozzle
spout in a bucket of warm water. This helps to dissolve the crystals. Ensure that the flowrate does not
exceed 10 I/min while the volume flow switch is set to '10 I/min' calibration position. If necessary,
follow the instructions to decrease the flowrate on page 12.
If dispensing is not possible due to failed dispenser heating (icing),
first bring back the heating
into service. Once a sufficient operation temperature is reached, dispense at least 3-4 1 AdBlue to
restore the full functionality.
If ZVA AdBlue LV still does not work properly,
please contact Elaflex.
*l Please note: multiple dispensing attempts (pulling the lever very often) without either test adapter
EW 22 or complete connection to the ISO 22241-5 tiller point lead to the formation of an overpressure
within the nozzle. This may temporarily inhibit the dispensing.
