Access lock
In order to lock the pump settings, it is possible
to use the « Access lock ».
To activate or deactivate it, proceed as follows:
• Put the switch 2 on ON position (Fig. 3, item S).
The <7.0.0.0> menu is called up.
• Turn the encoder / Press on arrows of the touch
pads to activate or deactivate the locking. The
current state of the locking is represented with
the following symbols:
Lock active: Parameters are locked,
the access to menus is allowed only
on reading.
Lock inactive: Parameters can be
changed, the access to menus is
allowed for setting.
• Return the switch 2 on OFF position (Fig. 3, item
S). The display returns to the status page.
6.1.6 Configurations
NOTE: If the pump is delivered as separate part,
not integrated into a system we mounted, the
standard configuration mode is
« Speed control ».
« Speed control » mode (Fig. 1, 2)
Setting of the frequency by hand or external
control.
• For the starting up, we recommend to set the
motor speed at 2400 RPM.
« Constant pressure » mode (Fig. 6, 7, 8)
Regulation with a pressure sensor and setting
point (internal or external).
• The addition of a pressure sensor (with tank;
sensor kit delivered as accessories) allows a pres-
sure regulation of the pump.
• The accuracy of the sensor shall be ≤ 1% and it is
used between 30 % and 100 % of the measuring
scale range. The tank must have a useful volume
of 8L minimum.
• For the starting up, we recommend a pressure set
value at 60% of its maximum pressure.
« P.I.D. control » mode
Regulation with a sensor ( temperature, flow,...)
by P.I.D. control and setting point (internal or
external).
6.2 Preliminary rinsing
The hydraulic features of every pump is tested
in factory, some water may remain in them. It is
recommended for hygien purposes, to carry out a
rinsing of the pump before any using with pota-
ble water supply.

6.3 Filling – degassing
CAUTION! Danger of material damage!
Never operate the pump dry, even briefly!
Pump in load (Fig. 2).
• Close the discharge valve (item 3).
• Open the venting plug (item 5), the suction valve
(item 2) and completely fill the pump.
• Close the venting plug only after water flows out
and complete aeration.
WARNING! Danger of burn!
In hot water, a stream of water may escape from
the venting plug port.
• Take all required precautions as regards persons
and motor-converter.
Pump in suction (Fig. 1, 4).
Two possible cases:
1st case (Fig. 4.1).
• Close the discharge valve (fig. 1, item 3), open
the suction valve (fig. 1, item 2).
• Remove the venting plug (fig. 1, item 5).
• Unscrew about 4 turns the bottom drain-priming
plug (fig. 1, item 6) located on the pump casing.
• Put a funnel into the venting plug port and com-
pletely fill the pump and the suction pipe.
• After water flows out and total air exit, filling is
achieved.
• Screw the venting plug and the bottom
drain-priming plug back in.
2st case (Fig. 4.2).
• Filling can be made easier by fitting a vertical
pipe (fig. 4, item 12) fitted with a Ø ½» stopcock
and a funnel, on the suction pipe of the pump.
• Close the discharge valve (fig. 1, item 3), open
the suction valve (fig. 1, item 2).
• Open the stopcock (fig. 4, item 12) and the filling
plug (Fig. 1, item 5).
• Fill the pump and the suction pipe completely
until water flows out of the filling plug and air
bubbles have completely disappeared.
• Close the stopcock (fig. 4, item 12) (which can
be left in place), remove the pipe and screw the
filling plug back in (fig. 1, item 5).
6.4 Starting up
WARNING! Danger of burn!
Depending on conveyed fluid and the operating
cycles of the pump, surface temperature (pump,
motor) can exceed 68°C.
• Take necessary means to avoid injuries!
CAUTION! Danger of material damage!
The pump must not operate at zero flow (closed
discharge valve) for more than 10 minutes with
cold water (T°C < 40°C) and more than 5 minutes
beyond 60° C.
• We recommend to ensure a minimum flow of
about 10 % of the pump nominal flow to avoid
any vapour lock at the top of the pump.
• Open the discharge valve and start the pump.
• Check pressure stability at discharge with a
manometer, if instability, perfect air draining.
