12. Plant starting

OFF
After completing hydraulic and electrical connection
and checked the preloaded pressure (for booster
set with membrane tank), start the plant as
indicated below:
Prime the pumps (see the pumps' instructions).
Pump with suction lift:
- Fill the suction pipe and the pump body by means
of the plug hole located close to the delivery port
of the pump.
- Fill the suction tube by pouring water through the
plug hole on the suction manifold of the pump.
Pump with positive suction head:
Open the gate-valve in the suction pipeline.
With suffi cient head, the water will overcome the
resistance of the non-return valve fi tted in the
suction side of the pump and will fi ll the pump body.
Otherwise, prime the pump with the plug hole near
the delivery port.
Never run the pump for more than fi ve
minutes with a closed gate valve.
Starting pump
Press the button
status from STOP to run. The pump starts up
with the acceleration ramp set to reach the wished
set-point.
When the motor start turning, check the
direction of rotation.
If the pump has been primed correctly, after a few
seconds the pressure will begin to increase on the
display.
If, after a few seconds of operation the pressure
remains at 0.0 bar, stop the pump by selecting
(stop) as priming has not been carried out correctly
and the pump is idling. Re-prime the pump and
repeat the starting up procedure.
12.1. Cascade mode plant starting
Check that all the cascade mode parameters are
with the desired values, the parameters that can
change the cascade mode operation are:
PC14 / PP13 Cascade
pressure setup.
PC15 / PP14 Cascade mode restart delay.
PC16 / PP15 Cascade mode fall pressure
limit setup.
To do the plant starting follow the instructions under
paragraph 12.
12.2. 12.2 Inversion of the direction of rotation
To change the direction of rotation of the motor push
the button (menu) and then with the button
(plus) or (minus) move up to the programming

parameter UP. Confi rm with
the button (plus) or

(menu) until you arrive on the basic display,
when you are out from the setup mode the icon
disappear.
12.3. Vessel pressure
Once the new working pressure is entered,
the tank preloaded pressure must be
changed to 2/3 if the working pressure (i.e. 4
bar working pressure, tanks to be preloaded
at 2.7 bar).

13. Use of megaohmeter

OFF
Measuring the resistance of an installation
incorporating the frequency converter is not allowed,
because the electronics may be damaged. If it is
necessary, disconnect the frequency converter and
use the megaohmeter directly on the terminal box
of the pump.

14. Maintenance

ON
Inspect the tank preloaded pressure of the delivery
vessel periodically.

15. Disposal

OFF
Observe the local regulations and dispose of any
control gear accordingly. This product contains
electrical and electronic components and should
fall
be disposed accordingly.
Separate the components using anti-cut water
resistant gloves. Is preferred to help to make a
further use or dismantling.
The device must be dismantled in different way
from normal. For disposal must be followed the
actual laws and regulation of the country where the
disposal is made, other than the international laws
and norms for ambient protection.
