Electrical Connections - Italtecnica Brio 2000 Manuel D'instructions

In the case of very high flow rates, the Brio 2000 device can be installed in a "by-pass"
mode, in parallel with a non-return valve placed on the main outlet, as shown in Fig. 06, to
reduce pressure drop.
7. b ELECTRICAL CONNECTIONS
Note: All electrical connections should be carried out by qualified personnel only, as shown
in Fig. 3.
In the case of pumps with power exceeding 500 W and an ambient temperature greater
than 25° C, heat-resistant cables (resistant to at least 105°C) must be used. Use only the
terminals supplied with the device.
In the version in which the connecting cable is included, simply connect the power plug of
the pump to the Brio 2000's electrical socket and the Brio 2000 device's plug, into a power
outlet. Note: the units supplied with 1 mm
For higher loads the supplied electrical cables must be replaced (by qualified personnel),
2
by at least 1.5 mm
The pump connected to Brio 2000 must be adequately protected against
current overloads.
8. CUT-IN PRESSURE ADJUSTMENT
CAUTION: Turning the adjustment screw will not alter the maximum pressure
delivered by the pump!
The pressure is factory pre-set at 1.5 bar, which is optimal for most applications. Different
working pressures may be obtained by adjusting the screw on the inner flange, which is
marked by the symbols + and -.
You may need to change the factory-adjusted pressure settings:
1) If the tap situated at the highest point is more than 15 metres above the Brio 2000 (fig.
05 – Hmax: 30 mt)
2) For increased load, i.e. when the load pressure is added to the pump pressure (max. 10
bar).
CAUTION: It is important that the MAXIMUM PRESSURE of the PUMP is at
LEAST 1.0 BAR HIGHER THAN the cut-in pressure set ON THE BRIO 2000
device.
9. COMMISSIONING
CAUTION: If the water level happens to be below the level at which the pump is
installed (negative head), it is imperative to use a suction hose complete with foot
valve to prevent water from draining back into the well.
Before switching on, make sure that both the suction pipe and the pump are primed. Start
the pump by switching on the Brio 2000 device. As soon as the pump stops running, open
the tap positioned at the highest point within the system.
If there is a steady flow from the tap, and the pump runs uninterruptedly, the
commissioning procedure has been successful. If there is no continuous flow, try to run the
pump for a short while by holding down the RESET button. If the problem persists,
disconnect the Brio 2000 device and repeat the whole procedure.
