INITIAL START UP

FOREWORD Only start dispensing after making sure that assembly and
installation have been correctly performed.
WARNING TOXIC FLUID OR FUMES HAZARD
The faulty operation of this device could cause the spill
of liquids that are hazardous for people and the envi-
ronment.
NOTICE It is a good practice to only operate the nozzle lever
after making sure the spout has been properly in-
serted in the mouth of the tank to be filled.
NOTICE When using for the first time and every time the
nozzle is used, following the connection of the sup-
ply hose, gently operate the lever to enable the air
to escape from the circuit, until normal operation is
achieved.
NOTICE Check the correct operation of the automatic stop
device once the tank is full.
NOTICE Keep fresh water in nozzle path to prevent DEF
crystals from forming on nozzle end. The nozzle au-
tomatic cut off may fail if crystallization plugs the
nozzle orifice. The nozzle tip must be submerged in
water when the nozzle is holstered.
