1. FEATURES
Brio 2000 is designed to automatize the starting and stopping operations of
an electric pump with regard to a drop in pressure (opening of the taps) and to
the stopping of the flow through the system (closing of the taps), respectively.
Brio 2000 stops the pump when senses the lack of water flow, preventing it
from any damaging dry operation.
Furthermore, thanks to a timer, it starts the pump automatically to verify an
eventual new water availability in the suction line – Brio2000-T and 2000-MT
versions only.
It is advisable using Brio 2000 with water systems whose water is without
sediments. In case it is not possible, it is necessary to install a filter before the
inlet of the device.
The pressure gauge checks the starting pressure value and the pressure in
the system.
Furthermore it verifies any possible presence of water leakages in the very
system.

2. SAFETY REGULATIONS
To avoid shocks and fire risks, read and follow closely the
following instructions:
• Always unplug the device from the mains before carrying out any
work on it.
• Be sure that the electric line connecting the device to the mains
and the extension leads have a cross-section suitable for pump
power and be sure that the electrical connections are far away from
any water source.
• When Brio 2000 is used for swimming pools, ponds and fountains it
is necessary to use an automatic RCD with IDn=30mA protection.
WARNING: when the pump stops the pipes are under pressure
consequently we recommend opening a tap to discharge the system
before carrying out any work.
PLEASE READ THIS INSTRUCTION LEAFLET CAREFULLY THROUGH
BEFORE INSTALLING AND OPERATING THE DEVICE.
ALL WIRING UP MUST BE CARRIED OUT BY SPECIALLY TRAINED
PERSONNEL.

3. OPERATING INSTRUCTIONS
The switch starts up the pump for 15 seconds once connected to the line. Any
further pump starting occurs when the pre-set operating pressure value is
reached, accordingly to the drop in pressure in the tubing when opening a tap.
In the traditional water systems equipped with pressure switch and pressure
tank, the pump stops when a certain pressure value is reached. Differently
Brio 2000 has been projected to stop the pump depending on the reduction of
the flow to minimum levels.
Once this circustance has been reached, Brio 2000 delays the real stop of the
pump of a timing running from 7 to 15 seconds: the logic of this function is to
reduce the starting operations of the pumps in case of minimum flow
conditions.
4. INSTALLATION
1. Install Brio 2000 anywhere between the pump and the first service outlet
so that the arrows moulded on the case and on the outlet connection are
pointing to the same direction as the fluid flowing through the pipe.
Check perfect water tightness of all water connections. If you are using a
pump with a pressure higher than 10 bar, install a pressure reducer on
the Brio 2000’s inlet.
2. For the electrical connection of the version supplied without electric
leads, follow the wiring diagram on the printed circuit board cover, or on
the drawing following. Furthermore, in case of use of a pump with power
higher than ½ Hp and the ambient temperature is higher than 25° C it is
necessary to wire Brio 2000 with cables with a thermic resistance not
inferior to 99°C. Use only suitable wire nippers to wire the Fastons. If the
leads are included, simply connect the pump’s power plug to the Brio
2000 socket and its own power plug to a current outlet.
3. Operating pressure is pre-set at 1.5 bar which is the optimum value for
the majority of applications. Minimum operating pressure can be
adjusted as needed by turning the screw situated on the inside flange
marked with + and -.

ATTENTION: the check valve installed in the pump outlet and in the Brio 2000
inlet can cause some anomalies during the normal working of Brio 2000.
Therefore it’s advisable avoiding its installation between the pump and Brio
2000.
4. Attention:
To modify the operating pressure adjustment it is necessary to take the
cover away. Skilful people only must handle that operation, taking care
of the electric-shock risks.
Such pressure adjustment modifies the starting pressure limit of the
pump. The exit pressure of device never increases. The pressure
difference between the operating pressure value – set on the device –
and the maximum pressure of the pumps must be higher than 0,6 bar.
When it is necessary to modify the adjustment:
1_When the higher top is situated at more than 15 mt higher of the
device (max water column: 30 mt).
2_For the applications of the pump in load, that is when the loading
pressure is added up to the pressure of the pump, max. 10 bar.

WARNING: TO ENSURE CORRECT WORKING OF THE BRIO 2000,
MAXIMUM PUMP PRESSURE MUST BE AT LEAST 0,6 BAR HIGHER
THAN BRIO 2000 OPERATING PRESSURE.
5. STARTING BRIO 2000
WARNING: whenever the level of the priming water is lower than the
level of the water where the pump is placed, a suction line equipped
with an antibackflow foot valve is absolutely essential. This valve allows
the line to be filled when it is first used and prevents it from being
emptied when the pump stops.
1. Before turning on, fill up the suction pipe and pump with water and then
start the pump by connecting the Brio 2000 power plug to a current
outlet; when the pump stops open the tap situated higher up.
2. Installation is correct if the flow from the tap is regular and if the pump
works continuously. If there is no water you can try to make the pump
work without interruption - for a period of time longer than the device’s
working time - by keeping the RESET button depressed. If the problem
persists, disconnect the Brio 2000 and repeat the procedure from point
1.
6. DRY STOP
The red FAILURE LED lits up with motor off to indicate a dry stop. To start the
system again press the RESET button after having checked the presence of
water in the suction pipe.
