7.2 Safety recommendations

Avoid access to the room enclosing FireSet for
unauthorised persons!
WARNING! Risk of cuts!
Do not remove the protection on any rotating
parts, belts, hot surfaces, etc. Never leave tools
or disassembled parts of the FireSet on it or
around it.
WARNING! Risk of fatal injury!
Do not remove the protection of live parts. Pre -
vent each possibility to operate elements that
isolate the installation or subassemblies on
which work must be performed.
DANGER! Risk of fatal injury!
Take all precautions to avoid a risk of electrocu -
tion. Check earth connection, presence and con -
tinuity, and if a device for protection against
indirect contact is installed (differential switch).
If necessary, operate the unit by using required
equipment (insulating gloves, isolating base -
plate).
Never leave the electrical switchgear or the ter -
minal box of electrical motor opened. Check if
there is any possibility of contact with live parts.
Check if electrical connections and auxiliary
power are correctly connected. Check the label
data of electrical switchgears, in particular ten -
sion and availability of an adapted power supply.
WARNING! Risk of fire or flash fire!
The charging diesel pump batteries may produce
potentially explosive gas; Avoid flames and
sparkles.
Never leave flammable liquids or rags dipped in
acid around the fire-extinguishing system or
electrical equipment.
DANGER! Risk of fatal injury!
Ensure the correct ventilation of the pump
room. Check that the exhaust of the diesel
motor is free and the tube allows exhaust gases
to remove outside the room safely, away from
doors, windows, and vents.
WARNING! Risk of burns!
Check that exhausting pipes are correctly sup -
ported, equipped with anti-vibration couplings/
flexible vibration-damping sleeves, and pro -
tected against accidental contacts.

CAUTION! Risk of damage of the installation
(System)!
Check if suction and discharge pipes of the
pump are supported correctly to avoid weight
load on the pump.
CAUTION! Risk of product damage!
Check that the fluid level of the diesel motor
(oil/water) is correct and that the plugs of the
water and oil circuit are properly fastened.
For internal combustion motors with heat
exchanger water/water, check that the valve of
the cooling circuit is in the correct position
OPEN.
Check oil and diesel fuel, then check if there are
no fluid leakages.
CAUTION! Risk of product damage!
For the heating of the oil/water of the diesel
motor, an immersion or contact resistor sup -
plied with 230 V/50 Hz may be installed.

7.3 Checking and environment

• Check electrical pumps or diesel pumps as men -
tioned in the Installation and operating instruc -
tions for both kind of pumps.
• Provide sufficient space (at least 0.8 m around the
FireSet Fig. 4b) for the maintenance of pump,
motor, switchgear, and installed accessories.
• The installation (system) must be evaluated to
ensure that the net positive suction head available
(NPSHA) exceeds the net positive suction head
required (NPSHR), as stated by the pump perfor -
mance curve.
• The foundation for the Wilo-FireSet must be rigid
enough to absorb any vibration and stress
encountered during pump operation. A raised
foundation of concrete is preferable for most
floor-mounted pumps. The raised foundation
ensures a satisfactory base, protects against
flooding, simplifies moisture drainage, and facili -
tates keeping the area clean. (Fig. 4)
• Bolt the Wilo-FireSet firmly to the foundation,
whether it is a raised concrete base, steel work
wall, or structural member. Position the mounting
bolts or lag screws accurately (Fig. 4)
• Prepare a surface with reinforced concrete
(RCK400) for installation of the fire-extinguishing
system. It has to be perfectly flat and horizontal as
shown in the book project, complete with bolts,
which have the diameter adapted to the weight of
the Wilo-FireSet. (See Fig. 4 -4a)
• Connect the pipes of different circuits without
mechanical stress, which can damage the equip -
ment or the pipes themselves
