7.1 Initial operations and general
checks
Refer to Appendix A before commissioning.
ƒ
Before initial commissioning, check that the wiring is correct, in particular the
ground connection.
ƒ
Ensure that rigid connections are not exposed to mechanical stress.
ƒ
Fill the system and search for possible faults during visual inspection.
ƒ
Open the shut-off valves on the pump side and on the pressure line.
CAUTION
Material damage due to dry run
The system must never run dry. Dry running will destroy the mechanical seal of the
pump.
If there is no more water in the jockey pump’s diaphragm pressure vessel, inflate it to
a pressure 0.5 bar lower than the starting pressure of the jockey pump.
Do not exceed the maximum inflation value for the diaphragm pressure vessel.
DANGER
Risk of fatal injury due to electrical current!
Do not remove the protection of live parts. Prevent any possibility of operating the
elements insulating the system or the subassemblies on which maintenance is to be
carried out.
CAUTION
Material damage!
Tighten all supply terminals before commissioning the pressure-boosting system!
If tests have to be carried out during installation, make sure that the pumps are cor-
rectly filled with water before switching them on.
Before filling the pump unit with water, check the tightness of the components,
which may have come loose during transport and handling.
Do not leave the pressure-boosting system in automatic mode before the fire-
fighting system has been completely assembled according to the standard. The
commissioning of an incomplete fire-fighting system will invalidate the warranty.
7.2 Procedure for commissioning
ƒ
When setting the automatic operation of the pump-motor unit, it is necessary to
define the procedures of the maintenance program and the responsibilities for inter-
vention in case of accidental starting.
ƒ
For diesel motor models, check that the batteries are correctly recharged before op-
eration.
ƒ
Follow the manufacturer's instructions when inspecting batteries.
ƒ
Keep batteries away from flames and sparks. For safety reasons, do not lean over the
batteries during operation and during their installation or removal.
ƒ
Check the fuel level of diesel motors and, if necessary, top up the fuel when the mo-
tors are cold.
ƒ
Do not spill fuel on motors or rubber or plastic parts of the system.
ƒ
Do not add fuel when motors are hot.
ƒ
Before switching on the main pumps check the correct alignment between pump
and motor. Qualified personnel must carry out the motor pump alignment.
ƒ
Only qualified technicians may carry out the installation.
7.2.1 System with positive suction head
The following measures must be taken when commissioning a system installed with
positive suction head:
ƒ
Check that the air vent valve of each pump is open.
ƒ
Close the valves on the delivery pumps.
ƒ
Slowly open the valves on the final pressure side and check whether water is leaking
from the vent circuit of each pump.
ƒ
Briefly start the pumps in manual operation.
ƒ
Make sure there is no air in the circuits and pumps.
