8 Commissioning

For the commissioning of the Wilo-FireSet, con -
tact the closest Wilo service agent or contact the
Wilo after-sales call centre.
Only an informed and skilled person must perform
the commissioning of the Wilo FireSet.

8.1 General check

Before starting the Wilo-FireSet commissioning
procedures, check that:
• The specification for installation in the NFPA20
have been applied
• The specification in the pump's Installation and
operating instructions have been applied
• The specification in the Switchgear`s Installation
and operating instructions have been applied
• The wiring was done correctly, particularly the
earth connection
• The rigid connections are not exposed to mechanical
stress
• There are no faults during visual inspection after
filling the system
• Gate valves on pump sides and on the discharge
pipe are open
• Fluids levels in the diesel motor are sufficient
• The pump/drive are correctly aligned
CAUTION! Risk of product damage!
Tighten all the supply terminals before commis -
sioning!
WARNING! Risk of cuts!
Ensure that all protections on any rotating parts,
belts, hot surfaces, etc., have not been removed,
or have been reinstalled. Never leave tools or
disassembled parts of the FireSet on it or around
it.
WARNING! Risk of fatal injury!
Ensure that all protections on any dangerous
parts have not been removed, or have been
reinstalled. Prevent each possibility to operate
element that isolate the installation or subas -
semblies on which work must be performed.
If it is necessary to conduct tests during installa -
tion, make sure that the pumps are properly filled
with water before switching them on.
Before filling the pump unit with water, check the
tightness of the components, which could be
loosened during transport and handling.
Do not let the FireSet in automatic mode before
the fire-extinguishing system is completely
assembled according to the standard; for the
commissioning of an incomplete fire-extinguish -
ing system no warranty claims will be accepted.

PROCEDURE FOR COMMISSIONING
• During the automatic mode setting, maintenance
program procedures and responsibility of opera -
tion in the case of accidental starting must be
defined.
• For models with diesel motor, check the correct
filling of batteries before operation.
• For inspection of batteries follow the instructions
provided by the manufacturer.
• Keep batteries away from flames and sparkles. For
safety reasons do not lean above the batteries
during operation, installation or removal.
• Check the correct level of fuel in tanks of diesel
motors and if necessary add fuel only when the
motor is cold.
• Be careful not to spill fuel on motors, on rubber or
plastic materials of the system.
• Do not add fuel when the motor is hot.
• Before switching on the electric pump, check the
correct motor-pump alignment. Respect opera -
tion from the specific Installation and operating
instructions delivered with the pumps. Only skilled
persons must perform the motor-pump alignment
operations.
• Only qualified technicians must perform the
installation.

8.2 Operation check

8.2.1 Commissioning of main electric pump

• Make sure that all hydraulic, mechanical, and elec -
trical connections indicated in the NFPA 20, in this
Installation and operating instructions, in the
Installation and operating instructions of the
pump, the motor and switchgear are done cor -
rectly.
• Ensure that the valves at the suction and the dis -
charge side of the pump are open.
• Ensure that the pump sucks and is filled with
water.
• Check that the power supply matches the data
indicated on the rating plate and that three-phase
power supply is connected.
CAUTION! Risk of product damage!
Make sure that none of the following points
exists. Otherwise immediately stop the pump
and remove malfunctioning causes before start -
ing it again (also refer to the chapter Faults,
causes and remedies):
• Rotating parts in contact with fixed parts,
• Unusual noises and vibrations,
• Loosened bolts,
• High temperature on motor housing,
• Differences in current at each phase,
• Leakages on pump body,
• Vibrations, noise, and excess temperatures
could be caused by a misalignment of the motor/
pump coupling.
