Made of medium-density polyethylene with ultraviolet filters, it has smooth, rounded surfaces that facilitate agitation
and cleaning. Range of volumes: 400, 600 and 1,000 litres.

3 - Description
Liquid circuit
Technical information
All the liquid circuit functions are operated via the MANIFOLD system and the pressure collector. The use of
pictorial symbols helps to clearly identify these functions.
HLC Circuit
The pressure circuit is called HLC (Hardi Liquid Circuit). designed
for diaphragm pump. The pressure collector is synthetic and deli-
vers the flow to three different places.
The HLC pressure collector is fitted with three mechanical valves
which allow the functions of the liquid circuit to be operated.
The first valve sends the flow of water with pressure to the
agitator. The second activates the powder mixer so as to
clean the filter at the entrance to the tank when powder has been
loaded through it(remember to close the valve after use or this
may cause a lack of pressure). The third valve activates the
rotary nozzle for cleaning inside the tank when it is cleaning the
liquid circuit with clean water.
Each function is identified by a pictograph.
(and are optionals)
The MANIFOLD System
Depending on the model, there may be a MANIFOLD valve. This is
a three-way manual valve that allows you to select the tank from
which the pump is to aspirate. It is black and is situated on the lo-
wer left-hand side of the blower, above the suction filter. Optiona-
lly, a blue return manifold valve can be fitted, which allows a return
flow circuit to be set up. This valve is to be found at the front of the
equipment, behind the operating unit.

Safety valve
The safety valve acts like a fuse when the circuit carries out an
operation that causes a sudden increase in pressure.
This valve normally keeps the return manifold in a closed po-
sition, by way of a spring and a washer. When the amount of pres-
sure in the circuit is above the maximum allowed for the valve, this
opens and allows the flow to return.
This valve is 15 bar.
Do not eliminate the safety valve from the liquid circuit as
this could put your safety at risk.

To avoid the hammering caused by pressure pulses in the liquid
circuit, the 321 pumps are fitted with an pressure damper. The
damper should be loaded at the pressure shown in the table on
top of the pulsation damper .

3 - Description
M70/2
Manual operating unit, comprises a pressure valve that is fitted
with a pressure gauge. By way of two valves, the right- and left-
hand sections of the spray line open and close. With the lever
on the left the flow is shut off from the nozzles and the return
manifold is opened up completely.
To start operation, one must increase the pressure using the red
han d l e to the left of the operating unit. Turn clockwise to
increase pressure or anti-clockwise to decrease it. Check the
pressure gauge to see when it is at the correct pressure level.

3 - Description
BKC/2
Manual operating unit that can be fitted in connection with the
diaphragm pumps.
By way of two lever taps, the right- and left-hand sections of the
spray line open and close.
Using a mechanical remote ON/OFF control, the flow is shut off
from the nozzles and consequently the return manifold is opened
or closed.
To start operation, one must increase the pressure using
the red handle situated in the centre of the operating
unit next to the pressure gauge. Turn clockwise to increa-
se pressure or anti-clockwise to decrease it. Check the
pressure gauge to see when it is at the correct pressure
level.
It is of utmost importance for the operating unit to be well adjus-
ted. For this reason, before using the equipment for the first time,
it is necessary to adjust the pressure equalisation valve.
During this procedure, the return manifold ofeach section is re-
gulated, so that itreturns the same amount of liquid to the tank as
is expelled through all its nozzles when open.
This avoids variations in pressure when one or two sections are
shut off.
The regulation procedure is the following:
1. Open the two sections via the electrical control box.
2. Put the pressure at, for example, 3 bar.
3. Close one of the sections or .
4. With the valve of the closed section, adjust the pressure
until the pressure gauge indicates 3 bar.
5. Open the section again and repeat the operation with the other
section.
6. Carry out a test by opening the two sections at the same time
or one by one. If the operating unit is perfectly adjusted the pres-
sure ought to be the same.
It is recommendable to carry out this adjustment at as near
a pressure as that at which the equipment is going to ope-
rate.
Carry out this adjustment every so often as somebo-
dy may accidentally change the position of the pressure
equalisation valve.

Electrical operating.
By way of an electrical control box fitted to the tractor, the swit-
ches that open or close the sections individually or together are
activated. The control box is also fitted with another switch to in-
crease or decrease pressure.
The functions of the control box are described below:
Switch to increase or decrease pressure.
Main On/Off Switch
Switch to open left-hand section.
Switch to open right-hand section.
Inside the box is the electronic circuit board and fuses for each
motor. Inside the box there are two spare fuses.
It is of utmost importance for the operating unit to be well
adjusted. For this reason, before using the equipment for
the first time, itis necessary to adjust the pressure equali-
sation valve.
During this procedure, the return manifold ofeach section is regu-
lated, so that itreturns the same amount of liquid to the tank as is
expelled through all its nozzles when open.
This avoids variations in pressure when one or two sections are
shut off.
The regulation procedure is the following:
1. Open the two sections and on the electrical control box.
2. Put the pressure at, for example, 3 bar.
3. Close one of the sections.
4. With the pressure equalisation valve of the closed section,
adjust the pressure until the pressure gauge indicates 3 bar.
5. Open the section again and repeat the operation with the other
section.
6. Carry out a test by opening the two sections at the same time
or one by one. If the operating unit is perfectly adjusted the pres-
sure ought to be the same.
It is recommendable to carry out this adjustment at as near a pressure as that at which the equipment is
going to work.
Carry out this adjustment every so often as somebody may accidentally change the position of the pressure
equalisation valve.

Air kit
Axial fan – Technical information
The fans on HARDI ZENIT mist blowers have been designed with composite blades and their aerodynamic design
offer a higher quantity and better distribution of air, less noise and less power consumption. They are also fitted with
a centrifugal clutch so as to start up and stop in a smooth way.
Flow levels go from 35,000 to 45,000 m3/h depending on the adjustments made to its components.
AXIAL AIR KITS
Model fan Fan Flow m3/h Gear Box
A750 750 mm 30.000 1 speed
AG750 750 mm 35.000 2 speeds
AG820 820 mm 45.000 2 speeds
The tractor P.T.O. should notexceed 540 rpm as there is
grave danger that the air kit may explode.
Keep away from the air inlets and outlets while the fan is
on. Some objects may be expelled from the air outlet or a
piece of cloth could be sucked into the air inlet.
The air kits are the most dangerous part of the machine. Do not
try to change any of the parts without consulting your nearest
dealer beforehand. Handling air kits in order to change their cha-
racteristics should be done by qualified people.
Adjusting the fan
The angle of the fan blades can be adjusted to 4 positions. They
normally come in position 3.
Decreasing the angle of the blades (minimum angle, position 1)
lessens the flow and decreases power consumption. By increa-
sing the angle (maximum angle, position 4) the flow increases,
but so does power consumption. In this way the mist blower can
adapt both to the different applications as well as the power of
the tractor.
To change the position of the angle of the fan blades you should
follow these steps:
1. Take off the suction grid.
2. Loosen the Allen screws without taking them out com-
pletely.
3. Loosen the Allen screws holding the nut at the back of the fan.
4. With both hands on opposite blades, turn them to the position wanted between 1 and 4. All the blades should
turn at the same time.
5. Finally, check all the blades are in the same position .
