Cut-In Pressure; Electrical Conection; Putting Into Operation - T.I.P. BRIO 2000 M Gebrauchsanweisung

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 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.

Electrical conection

The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch): ∆ = 30 mA (DIN VDE 0100-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H07RN-F (3 x 1,0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splashwater-proof design.
The mains plug of the automatic control system connects directly to electrical mains through a suitably grounded
(SCHUKO) mains socket which is to be installed properly. During operation, the green indicator light shows the
presence of voltage within the system. The mains plug of the pump is to be connected to the socket of the Brio
2000 M.

Putting into operation

Please avoid any direct influence of moisture on the device (for instance when operating
irrigators). Do not expose the unit to rain. Make sure there are no dripping connectors above
the device. Do not use the device in wet or moist environments. Make sure that the device
including any electrical plug connectors are installed in a flood-proof location.
Prior to putting the unit into operation, please fill the suction line and the pump casing completely with liquid. Plug
the mains plugs of the pump into the socket of the Brio 2000 M. Then use a properly installed grounded (earthed)
mains socket to connect the Brio 2000 M directly to mains. The green indicator lamp on the Brio 2000 M goes on
