1. General information
These instructions are designed to ensure the correct installation and best use of our
automatic constant water pressure assemblies.
If you have any doubts, plessure consult your specialist dealer.
The assemblies are completely silent and are designed to provide an automatic supply
of clean water to one or two dwellings.
The 02 is a compact kit comprising a pressure gauge, check valve, electronic circuit and
reset button. It is designed to maintain constant pressure. It does not permit the pump to
operate without water and avoids water hammering. It requires no preloading of air or
adjustment. It has a water reserve to prevent the unit from being started by a dripping tap.
If water consumption is more than 0.3 l/m, the pump will operate continuously.
Our units are constructed with the finest materials and are subjected to the most
rigrous hydraulic and electrical controls,painstakingly verified.
By strictly following the instructions for installation and use of the pump, and paying
careful attention to the wiring diagrams you shall avoid the possibility of overloading the
control circuit or any other problems associated with misuse,for which we can accpet
no responsibility.
When the pump reaches maximum pressure the unit automatically switches the pump
off. Unit seleyion must take into account the fact that the differential must be over 1.4Kg.
2. Installation
The 02 Kit has a 1*BSP threaded male fitting which can be screwed directly
into the pump, and 1* BSP female for connection to discharge pipework.
The assembly should be protected from the risk of flooding and installed in a
sheltered place but wellventilated place.
If the pump to which the Kit is fitted is directly connected to the mains supply,
it must be remembered that the incoming pressure must be added to that
provided by the pump. Total pressure may never exceed bar.

It can be fitted to any installation that has sufficient feed flow.
See installation diagrams.
3. Discharge pipework assembly
The discharge pipework diameter should be equal to or larger than that of the
pump discharge. It should not rest against the pressure unit and should be
checked for watertighrness.
No check valve needs to be installed.
4. Electrical connection
5. Controls prior to start up
Before first starting the pump ensure:
That the grid voltage and frequency match those featured on the specification
plate.
That the pump shaft turns freely.
That the pump boby is completely full of water-fill by unscrewing the
corresponding priming plug.
THE PUMP SHOULD NEVER BE OPERATED DRY .
SEE INSTALLATION DIAGRAMS.
6. Start-up
Open all gate valves in the suction and discharge lines. Switch on the power and the
pump will start automatically. While doing so, leave the discharge tap open to bleed
any air there may be in the system. Then, close the tap and the assembly will shut
down when it reaches maximum pump pressure.
Verify the motor sense of rotating is clockwise, checked from the fun cover (Fig. 2).
If the pump is not properly primed or these is no water supply, it will shut down after
30 seconds.
Once the water level is recovered and the pump has been properly primed, repeat the
start up operation, this time holding in the red reset button for a few seconds．
If the assembly does not operate, does not produce pressure or does not shut down,
try to discover the cause of the problem consulting the troubleshooting guide provi-
ded below.
