6. STARTING UP
If the pump is delivered as an individual part, as
CAUTION !
not integrated into a system we mounted, the
standard configuration mode is either the MODE 1-3, or the MODE 2
following the driven mode choose at the order of the pump.
Reminder : The change of the converter parameters from Mode1-3 to
Mode2 (or reverse) is carried out by the programming key, the action
of an after-sales technician is required.
6.1 Configurations
- In manual mode : MODE 1 (see fig. 1 - 2).
When changing the motor speed with the potentiometer (fig. 10 -
item 19 ) you reach the working point of the pump ; from 40 to 100%
of the maximum speed.
For the starting up, we recommend to regulate the motor speed at
70 %.
- In mode with pressure regulation : MODE 2 (see fig. 7 - 8 - 9).
The addition of a pressure sensor and a tank allows a pressure regu-
lation of the pump.
The accuracy of the sensor is ≤ 1% and it is used between 30 % and
100 % of the measuring scale range. The tank must have a useful
volume of 8L minimum. With no water in the tank, pressurize the tank
to a pressure 0.3 bar less than the pressure regulation of the pump.
(tank and sensor kit delivered as accessories).
The set value for pressure regulation is put :
• The adjustment by the potentiometer give a set value between 0
and 100% of the sensor range, for the starting up, we recommend to
regulate the potentiometer at 100 %.
• By an external signal (0-10V or 0-20 mA ) for driving the pump from
outside (see § 5.3 – Electric connection).
REMARK : The function « detection of zero flow » allows the stop of
the pump.
- With external control of frequency : MODE 3 (see fig. 11)
The potentiometer has no function any more, the pump is control-
led by an external signal.
For the starting up, please refer to the users instruction of the booster.
In normal operation the state of the leds is as follows (fig. 10 - item 17-18)

6.2 Preliminary rinsing
Each of our pumps is tested regarding hydraulic features in
factory, some water may remain in them. It is recommended
for hygien purposes, to carry out a rinsing of the pump befo-
re any using with potable water supply.
6.3 Filling - degassing
Never operate the pump dry,
CAUTION !
even briefly.
Pump under pressure (see fig. 2)
- Close the discharge valve (item 3).
- Open the venting plug (item 5), the suction valve (item 2) and com-
pletely fill the pump. Close the venting plug only after water flows
out and complete aeration.
Pump in suction (see fig. 1) : two possible cases.
1st case (see fig. 5.1)
- 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 completely 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.

2nd case (see fig. 5.2)
Filling can be made easier by fitting on the suction pipe of the pump, a
vertical pipe (fig. 5 - item 12) fitted with a Ø 1/2" stopcock and a funnel.
The length of the pipe must be at least 50 mm tal-

ler than the venting plug level.
- Close the discharge valve (fig. 1 - item 3), open the suction valve
(fig. 1 - item 2).
- Open the stopcock (fig. 5 - item 12) and the venting device (fig. 1
- item 5).
- Unscrew about 4 turns the drain-priming plug (fig. 1 - item 6).
- Completely fill the pump and the suction pipe until water flows out
of the venting plug (fig. 1 - item 5).
- Close the stopcock (fig. 5 - item 12) (which can be left in place),
remove the pipe, close the venting device (fig. 1 - item 5) and
screw again the drain-priming plug (fig. 1 - item 6).
6.4. Starting up
Depending on conveyed fluid and running of pump, surface
temperature can exceed 68°C. Take necessary means to
avoid injuries.
The pump must not operate at zero flow (closed dischar-
CAUTION !
ge valve) for more than 10 minutes with cold water (T°C
< 40°C) and more than 5 minutes above 60 °C.
We recommend to ensure a minimum flow of about 10 % of the nomi-
nal flow of the pump to avoid the formation of a vapour lock at the
top of the pump.
- Keep the discharge valve closed.
- Start the pump.
- Open draining plug to drain air. If no water leaks within 20s, close the
plug and stop the pump, then wait 20s to allow air to settle.
- Start again the pump.
- If necessary (particularly if the suction height exceeds 5 m) repeat
these operations.
- If water leaks at draining plug (it means the pump delivers its pres-
sure), slowly open the discharge valve. The pump has to be primed.
- Check pressure stability at discharge with a manometer, if instabili-
ty, perfect air draining.
- In case of failure, do the filling in again and start the operation again.
- To perfect air draining, close the discharge valve and the draining
plug, then stop the pump 20s, start the pump again and open the
draining plug. Do it as long as air comes out.
- Open the discharge valve in order to have the wished working
point.
- Check that the current input does not exceed the value indicated
on the identification pump plate.
