INSTALLATION

HYDRAULIC CONNECTION:

Brio Top must be installed on the pump delivery in a horizontal or vertical position, in observance of the
flow direction indicated by the arrow on the cover. The water on the pump outlet passes through the
device for subsequent distribution to the various utilities.
The water entering the Brio Top must be free of impurities and/or other substances that could prevent
movement of the check valve on the interior. To minimise this problem special filters should be fitted on
the pump intake.
Install a small expansion vessel (1-2 litres) downline of Brio Top, to limit restarts caused by small leaks,
the presence of which is normal on most systems.
The pre-load valve of the expansion vessel must be suitable for the set pressure values. This provision
also helps to improve constant performance levels in the event of low water demands by the system (e.g.
washing machines, WC flushes, etc.).
It is essential that no check valve is installed between Brio Top and the electric pump or between the
device itself and the utilities, as this may cause device malfunctions.
However, a check valve may be fitted in the electric pump intake line to
avoid drainage at the time of shutdown.
The device should not be installed in pits or watertight enclosures where there is a strong risk of
condensation.
CAUTION: when the pump stops the pipes might be still under pressure; therefore, before any
intervention, it is advisable to discharge the system by opening a tap.
CAUTION: this device is not to be considered a mechanical pressure reducer and therefore all
system parts must be sized according to the maximum supply pressure of the pump.
EXAMPLE OF INSTALLATION IN TWIN
BOOSTER SETS
Connect the intake lines of the pumps to a common
manifold and install one Brio Top on the delivery
line of each electric pump. The device outlet
couplings must be connected to a single delivery
manifold, which must be connected to the
expansion vessel.

EXAMPLE OF INSTALLATION ON
SINGLE ELECTRIC PUMP:
H
Brio Top can be fitted on submerged or
surface pumps. Pressure settings must take
into account the water column (H) on outlet
from the device, considering 0.1 Bar pressure
per metre of water column.
