Installation and operating instructions Wilo-SiFire System 41
9 Maintenance
The fire extinguishing system is a safety equip-
ment that protects objects and people, therefore
possible modifications and repairs that affect its
efficiency must be made so as to minimise the ‘out
of order’ state.
Isolate pumps one at a time by the selector
switches of electrical panels and the stop valves
provided for this purpose.
Prohibit access to the pump room to unauthor-
ised persons.
WARNING! Risk of personal injury!
People must always wear personal protective
devices. Maintenance must be performed ONLY
by qualified personnel. In case of lack of instruc-
tions, always contact the supplier or expert
staff.
Never work alone on works which require the
presence of more than one person.
Do not remove the protection on any rotating
parts, belts, hot surfaces etc. Never leave tools
or disassembled parts of the group on it or
around it.
Do not remove the protection of live parts; pre-
vent every possibility for operate any element
that isolates the installation or subassemblies
on which to work.
CAUTION! Risk of product damages!
The booster is NOT equipped with an emergency
stop. The main pumps can only be manually
stopped by cutting automatism.
For this reason before making an intervention
on pumps, be sure to be in possession of opera-
tion key (if existing) of automatic/manual
switches.
Open the general isolating switch on the electrical
panel of the concerned pump.
DANGER! Risk of fatal injury!
In case of interventions with the control panel
door open, even after opening the main isolating
switch, input terminals from the supply line and
those of remote transmission of alarms could
still be powered.
DANGER! Risk of fatal injury!
For an intervention on the diesel engine, it is
advisable to disconnect the positive terminal of
battery to prevent undesired start-ups.
DANGER! Risk of fatal injury!
Before changing the engine oil, make sure the
temperature is below 60 °C. For water-cooled
engines, very slowly remove the radiator cap or
the heat exchanger. The cooling systems are
normally under pressure and violent hot liquid
leaks could occur. Check the correct level of
engine fluids (oil/water) and the correct tight-
ening of the water circuit and the circuit oil clo-
sure plugs.
Never add coolant to an overheating engine, let
it cool first !
For diesel engines, with heat exchanger with
water/water, check that the valves of the cool-
ing circuit are locked in open position. Check
diesel and oil hoses and see if there is no fluid
leakage.
NOTE:
For oil/diesel engine water heating, emersion or
contact supplied with 230V resistance can be
installed.
WARNING! Risk of fire and personal injury!
Connecting or disconnecting the battery can
produce sparks.
Never connect or disconnect the battery cables
when the motor is running.
WARNING! Risk of burn!
Hot diesel engine and exhaust pipe surfaces.
DANGER! Risk of explosion!
While charging the diesel pump batteries,
potentially explosive gas could be formed; avoid
flames and sparks.
Never leave flammable liquids or rags soaked
with these liquids around the unit of pumps or
electrical devices.
do not smoke
nor
use flames during the change of engine oil or
fuel provision.
Groups installed in accordance with these instruc-
tions will operate normally with a minimum main-
tenance intervention. Inspections and periodic
controls are planned and specified by the
EN 12845 standard in order to keep the fire extin-
guishing system and the pressure boosters effi-
cient. Refer to the weekly, monthly, quarterly,
semiannual, annual, triennial and 10-years pro-
gram of inspections and checks, prescribed by the
EN 12845 standard.
Maintenance must be performed by qualified per-
sonnel.
