rather than the cut-out pressure. The device delays the pump from stopping
for a further 7 – 15 seconds, thus reducing pump cycling in low flow
conditions.
7. INSTALLATION
7.a HYDRAULIC CONNECTIONS
Brio tank can be installed either in a vertical or a horizontal position, anywhere
between the pump outlet and the first outlet (tap). Care must be taken to
ensure that the direction of the arrow on the cover is in the same direction of
the flow of the fluid within the pipes (fig. 08). All hydraulic connections must be
properly tightened. An adequate pressure reducing unit must be fitted on the
delivery port of any pump exceeding 10 bar working pressure.
CAUTION: With the exception of submersible pumps, installing a non-
return valve between the pump outlet and the Brio tank inlet may
adversely affect pump operation. (The pump may fail to stop)
If it is necessary to install a non-return valve, this must be mounted at least 3
meters away from the device (fig. 07).
In the case of very high flow rates, the Brio Tank 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. 2. 04.
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 Tank's electrical socket and the Brio Tank
device's plug, into a power outlet. Note: the units supplied with 1 mm
is suitable for maximum loads up to 10A. For higher loads the supplied
electrical cables must be replaced (by qualified personnel), by at least 1.5
2
mm cable.
The pump connected to Brio Tank must be adequately protected
against current overloads.
