This symbol together with one of
the following words "Danger" or
"Warning" indicates the risk level
deriving from failure to observe the
prescribed safety precautions:
RISK OF ELECTRIC SHOCK
Warns that failure to observe the
precautions involves a risk of
electric shock.
DANGER
Warns that failure to observe the
precautions involves a risk of
damage to persons and/or things.
WARNING: Warns that failure to
observe the precautions involves
the risk of damaging the pump and/
or the plant.
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, please
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.
Our units are constructed with the
finest materials and are subjected
to the most rigorous 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 accept no responsibility.
When the pump reaches maximum
pressure the unit automatically
switches the pump off. Unit
selection must take into account
the fact that the differential must be
over 1.4Kg.
INSTALLATION
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.
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.
ELECTRICAL CONNECTION
Nominal pump current should be no
hogher than 10 A and the maximum
motor power (P1) should never
exceed 1.8Kw.
Ensure that all the connections
between the electronic circuit and
the power and motor cabled are
properly made.
To ensure correct connections see
the wiring diagram (Fig.3).
The protection of the system should
be based on a differential switch
(1 fn =30 mA). The supply cable
should comply with EEC standards
(2) or be of type
H07 RN-F as per VDE 0620.
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.
