15 Outlet water loss during
normal functioning.
16 Continuous outlet water
loss when the cabinet is
OFF.
17 Irregular water flow on
nozzle, difficult to regulate
by means of the dedicated
adjustment screw.
18 The nozzles produce
water jets without air.
19 The inlet water pressure
rapidly decreases. As a
consequence also the
output pressure decreases.
20 Ambient humidity far
below the set point.
21 The cabinet instructs the
electrovalves to open but
there is neither water
nor air circulation.
Keys: C=cause, S=solution
C1: Water loss from the N.O.
valve due to impurities or
defects.
C1: Water loss from the N.C.
valve (at the cabinet head).
C1: Nozzle clogged with dust
or impurities coming from
the air or water line.
C2: Out-of-range air and
water pressures.
C3: Oil in the air line.
C4: Nozzle blocked due to
incorrect cleaning cycle
selection.
Inverted water/air input
connection.
Insufficient delivery air
pressure.
The capacity of the entire
installation has been
underrated in relation to
the ambient requirements.
C1: Inputs/outputs mixed up.
C2: Insufficient delivery
pressures.
C3: The electrovalves of the
lines are clogged.
S1: Remove and clean the N.O. electrovalve.
S1: Remove and clean the N.C. electrovalve.
S1: Remove and clean the atomizing nozzles; if
necessary clean the line.
S2: Check the values of the pressure at the cabinet output.
If the water/air line is very long, measure the
pressure at the atomizing nozzles.
S3: Check the conditions of the filter/oil separator of the
compressor.
S4: Set the OFF cleaning cycle correctly (see page 24).
During the OFF routine, pressure must reach 0bar
and the pin inside the nozzle must clean the orifice.
Invert the line/water connection to the heads.
Check the capacity of the compressor in relation to the
consumption of the entire installation.
Adjust the nozzles again (set max. opening; see points
12 and 13 above). If this solution doesn't prove satisfactory,
it is necessary to add further atomizing nozzles in relation
to the max. capacity of the cabinet and compressor and
with respect to the conditions of the air to be treated in
the duct.
S1: Check that the I/O of the water and air lines are
correctly connected.
S2: Check the indications of the input pressure gauges.
S3: Check the condition of the electrovalves.
