CAUTION!
Ø
End of the line to the main tank must be open to the atmosphere and line pressure must be
zero, otherwise no healthy modulating operation can be ensured since the pressure, which is
to form in return, will also affect nozzle pressure. Fuel may drop from nozzle end during
stops.
Ø
For good pulverization, periodically check durability of the o-ring. In the event of earing of
the o-ring, fuel to the nozzle can by-pass and go directly to the return and reduces the
working performance of the nozzle.
Ø
Maximum operating pressure of the nozzle is 30 bars, while its maximum operating
temperature is 140ºC. These values should not be exceeded during working. Even if these
out of control value are exceeded, nozzle must be taken to emergency maintenance and all
O-rings must be replaced.
Ø
Do not use solvent based materials (thinner and derivatives) during cleaning of the fuel
nozzle; clean with gas oil or diesel oil. Fuel nozzle inner kit is very sensitive and even
invisible deformations can reduce working performance; dismantling-installing work must
be performed only by trained personnel.
Ø
Spring has lost its function if dropping from fuel nozzle or fuel exit at large scale is observed
when the nozzle performs circulation. It must be checked and replaced if necessary.
