Installation and operating instructions Wilo-SiFire System

• Check the oil and coolant level of the engine.
• If engines are cooled by water through a radiator 

or heat exchanger, check specific operations 
specified in the instruction manual of the engine. 
To top up the level of fluids, use oil and coolant 
advised by indications given in the instruction 
manuals of diesel engines in annex to this instruc-
tion manual.
Follow the commissioning procedures with help of 
the instruction manual of diesel pump box.

CAUTION! Risk of product damages!
To avoid overheating which could damage the 
main pumps, always check that the water flow 
through the recirculation circuit is fitting with 
requirements of pump technical sheet. If there 
are problems in recirculation circuit or if the 
minimum flow level used to test start and run-
ning of pumps is not guaranteed, open other cir-
cuits (for example, the flow meter, valve for 
testing the tightness of gate valve, drain valve, 
etc).

WARNING! Risk of false reaction of the opera-
tor!
The engine’s accelerator lever is locked. For that 
reason, the engine always starts at max speed!
Allow the pump to run for 20 minutes to check if 
the speed motor is compatible with the indica-
tion on the group label. 

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
• Exhaust gas in the pump room
• Leakage on mechanical seal

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

8.4.3 Commissioning jockey pump

Manual Start

Follow commissioning instructions with help of 
the manual of jockey pump box.

If the rotation direction is not correct, turn off the 
electrical supply of the box and switch two out 
three positions of phases in the control panel sup-
ply line. Do not invert with the yellow-green earth 
connection wire. 

CAUTION! Risk of malfunction!
For the jockey pump which maintains pressure 
on the installation, make adjustments, for 
example insert a diaphragm or a valve, to ensure 
that even if just one sprinkler is opened, the 
jockey pump does not compensate this.
For adjustments of jockey pumps, see the curves 
of different models of pumps mentioned in the 
catalogue. 

If there are troubles for starting pumps, refer to 
the chapter faults, causes and solutions of the 
jockey pump box and pump instruction manuals.

8.4.4 Filling of installation

If the unit is not filled, use the jockey pump after 
checking that the operations described in previ-
ous chapter have been correctly done.
In that phase, open one or more drain pipes on the 
sprinkler circuit to bleed air from the system.
Start the jockey pump. The system is slowly filling, 
expelling air out of the system. Once water starts 
to flow from drain pipes, close them and wait until 
the predetermined pressure is reached and the 
jockey pump stops. If the pump does not stop, 
check if there are no leaks and check again the 
calibration of the pressure switch which controls 
pump.
Once the unit has reached the set pressure, which 
must be higher than the automatic main pump 
start-up pressure, wait that the pressure remains 
stable before turning the system on automatic 
mode.
