5.1.

General installation information

During the entire process of installation, the devices must not be connected to the electrical
mains.
The pump, the Brio 2000 M electronic pump control and the entire collection system have to
be protected from frost and weather influence.
When installing the unit, please make sure that the connection cable is not subjected to
excessive pulling strain since this may cause damage to the electrical line and the electrical
connector.
When the pump stops in normal operation, the pipe system is under pressure. Therefore, a
consumer is to be opened prior to any intervention to make sure that the pressure will be
relieved.
All connection lines have to be perfectly tight since leaking lines may affect the performance of the pump and
cause considerable damage. Therefore, please use Teflon tape to seal the contact surfaces between the
threaded sections of the lines and the connection with the pump. This use of sealing material such as Teflon tape
is the only way to ensure an airtight assembly.
Avoid when tightening screw excessive force that may cause damage.
5.2. Installation of the Electronic Pump Control
The Brio 2000 M electronic pump control can be installed at any position between the pressure port or pressure
line of the pump and the first consumer - for instance a water tap. However, it is recommended to install the unit in
the close vicinity of or directly on the pressure port of the pump.
When using the supplied double nipple the side of the double nipple provided with O-ring must be screwed into
the pump. The double nipple without side O-ring is screwed into the rotatable coupling nut (8) of the pump control
(FIG. VII). Check that the gasket is properly inserted into the nut. If the fitting is carried out properly, the pump
control must not be turned by hand.
When installing the Brio 2000 M electronic pump control, please make sure that the arrows on its cover lid and
outgoing port point in the flowing direction of the liquid being discharged. Subsequently, the outlet port of the Brio
2000 M and consumer is to be connected to a suitable water pipe.
If you are using a pump with a maximum pressure of more than 10 bar, you have to install an upstream pressure
reducer which limits the max. operating pressure to 10 bar.
To ensure the perfect running of the electronic pump control, the intake line of the pump is to be equipped with a
check (or non-return) valve or a foot valve in order to maintain the pressure inside the water supply system after
the pump cuts out. This applies also to the use of a deep-well or submersible pressure pump (fig. IV.).
5.3.

Cut-in Pressure

Changing the preset cut-in pressure must only be done by qualified staff.
The difference between the cut-in pressure set on the Brio 2000 M and the maximum pressure
of the pump must be higher than 0.6 bar.
The cut-in pressure of the Brio 2000 M electronic pump control was set to 1.5 bar in the factory. If this value is to
be modified, the cover lid of the device has to be removed. To avoid any risk, this must only be done by qualified
staff, for instance by a qualified plumber or electrical shop. The cut-in pressure is set using the screw provided at
the inner flange. Rotating this screw in the direction of the plus sign ("+") will increase the cut-in pressure, rotating
the screw in the direction of the minus sign ("-") will decrease it (fig. VI).
Experience has shown that the preset value of 1.5 bar is ideally suited for most installations. However, a
modification may become necessary in the following cases:
1. The "h" height difference between the Brio 2000 M electronic pump control and the highest consumer exceeds
15 m (fig. V).
2. The pump is working in flooded-suction mode which means that the intake pressure adds up to the max. pump
pressure. Please note that any modification of the setting will only influence the cut-in pressure of the pump.
Increasing the pressure at the outlet point of the pumped liquid is not possible in this way.
