• Before turning on the main pumps, check the cor-

rect motor-pump alignment. Respect operation 
from the specific manual delivered with pumps. 
The motor-pump alignment operations must be 
performed by skilled persons.

• If the group is provided with pumps placed on a 

separate base frame, each base frame must be 
fixed to the ground, with a special attention to the 
alignment of the discharge manifolds.

• The installation must be performed by qualified 

technicians. 

8.2 Group under the charge of water

For the commissioning of a system installed under 
the charge of water, perform the following opera-
tions:

• Check that the air ventilation valve of each pump 

is open.

• Close valves on the discharge side of the pumps.
• Slowly open the valves on discharge side and 

check if water is coming out from the air ventila-
tion circuits of each pump.

• Briefly start pumps by using the manual mode. 
• Make sure air is not present in circuits and pumps.
• Repeat the operation until to be sure that all the 

air in the pipe is eliminated.

• Close the ventilation plug of the jockey pump. 
• Completely open the valves on the suction and 

discharge. 

• Make sure there are no problems of water flow 

(presence of dirt, solids, etc).

8.3 Group over the charge of water (Suction)

For the commissioning of a system installed above 
the level of water charge, perform the following 
operations: 

• That the ventilation valve of each pump is open. 
• Close valves on the discharge side of the pumps.
• Fill the main pumps through circuits from priming 

tanks.

• Fill the jockey pump through the filler cap by fol-

lowing instructions given the instruction manual. 

• Briefly start pumps by using the manual mode. 
• Make sure air is not present in circuits and pumps.
• Repeat the operation until to be sure that all the 

air in the pipe is eliminated. 

• Completely open the valves on the suction and 

discharge.

• Make sure there are no problems of water flow 

(presence of dirt, solids, etc).

8.4 Control operating

8.4.1 Commissioning of the main electric pump 

• Make sure all hydraulic, mechanical, and electrical 

connections, indicated in this manual, are cor-
rectly done. 

• Make sure the valves at the suction and discharge 

side of the pump are open. 

• Make sure the pump is primed and filled with 

water. 

• Check that the power supply matches with the 

one reported on the label and that three-phase 
power supply is connected. 
Follow commissioning instructions with help of 
each manual of electric pump box.

CAUTION! Risk of product damages!
In order to avoid overheating risking to damage 
main pumps, always check through recirculation 
circuit that the water flow is in accordance with 
instructions on technical manual of the pump. If 
troubles appear concerning recirculation circuit 
or if the minimum level necessary for testing 
start-up and pump running is not guaranteed, 
provide to open other circuits (for example, the 
flow meter, valve for testing the tightness of 
gate valve, drain valve, etc)
CAUTION! Risk of product damages!
Make sure that none of the following points 
exist. Otherwise, immediately stop the pump 
and remove malfunctioning causes before start-
ing it again (also refer to chapter faults, causes 
and solutions): 

• Rotating parts in contact with fixed parts 
• Unusual noises and vibrations
• Loose  bolts
• High temperature on motor housing
• Differences in current at each phase
• Leakages on mechanical seal

Vibrations, noise and excessive temperatures 
could be due to misalignment of motor/pump 
coupling.

8.4.2 Commissioning of the main diesel pump 

• Make sure all hydraulic, mechanical, and electrical 

connections have been made as indicated in this 
manual.

• Make sure that valves on suction and discharge 

side of the pump are open. 

• Make sure the pump is primed and full of water, 

and drain air by using the tap on the pump hous-
ing.

• Check if the supply voltage is in accordance with 

data reported on the label and if it is present.

• Make sure the fuel is compatible with engine 

functioning, then that the fuel tank is full of fuel 
(the fuel level inside the tank can be seen via the 
pipe gauge near to the tank).

• Make sure that connections are correctly made 

with pipes, without any connection between the 
tank and the engine

•  Make sure the electric float cable of tank is cor-

rectly connected to the electrical control panel of 
the diesel pump.
