Installation and operating instructions Wilo-FireSet UL FM

• Check the fluid levels of the diesel pump unit
(engine oil, fuel, water for cooling, battery fluid,
etc.). If necessary, restore the levels in accordance
with Installation and operating instructions of the
diesel motor.
CAUTION! Risk of contamination and damage to
health!
Protect fire pump buildings or rooms with diesel
motor pump drives and day fuel tanks (water
-
proof), against the risk of contamination of the
subsoil because of possible diesel or engine oil
losses.
7.4 Electrical connection
7.4.1 General
DANGER! Risk of fatal injury!
Have the electrical connection carried out by
authorized and trained personnel in accordance
with the applicable standards and laws. Power
supply must be available at any times.
• Check the type of power supply and the available
voltage, and compare them with the data of
pumps, motors, electrical switchgears, and other
devices. Check earth connection before any inter
-
vention.
• For connection to power supply networks use
one-piece cables without joints, exclusively dedi
-
cated to the FireSet unit for the fire department,
connected before the main power supply switch
of the buildings.
• Use cables with a suitable diameter whose charac
-
teristics and dimensions are in compliance with
standards in force.
• To protect the cables from direct exposure in case
of fire, they must pass through the pipes buried
outside the building or through parts of the build
-
ing where the fire hazard is negligible. If it is not
possible, they must also have an extra direct pro
-
tection with at least 180-minutes fire resistance.
• Make connections as shown and described in the
Installation and operating instructions and in the
wiring diagrams supplied with the switchgears.
• The main electronic switchgear must be located in
a fire-protected compartment, exclusively used
for power supply.
• Electrical connections in the main power distribu
-
tion box must be made to ensure that electricity
remains supplied to the pump switchgear even
when power is cut to other utilities.
• Connect batteries for diesel pumps before com
-
missioning.
• Check the tightening of all electrical connections.
7.4.2 Hydraulic connection
Refer to Fig. 5 for FireSet Electric and Fig. 5a for
FireSet Diesel.
Take in account the important information in the
Installation and operating instructions of the SCP
FF pump provided with the FireSet documenta
-
tion.
SUCTION PIPE:
Keep the suction line short, but not less than ten
pipe diameters in length, and direct with as few
elbows and fittings as possible to keep head loss
arising from friction at a minimum. However, lay
the suction line in an uninterrupted minimum
length of ten pipe diameters to the pump suction
flange. Lay a horizontal suction line with a gradual
rise to the pump, and pass under any interfering
piping.
Design the suction pipe diameter with at least the
same diameter as the suction nozzle on the pump,
and preferably larger. The use of a smaller diame
-
ter pipe results in loss of delivery head due to fric
-
tion. All joints must be tight to maintain prime on
the pump.
REDUCERS:
Install eccentric reducers directly on the suction
nozzle, with the taper at the bottom to prevent
the formation of air pockets. Never use straight
cone reducers in a horizontal suction line because
of the air pocket formed at the leg of the reducer
and the pipe. Refer to Fig. 5-5a.
DISCHARGE PIPE:
Dimension the discharge pipe as short and direct
as possible, with only few elbows and fittings to
reduce head loss arising from friction.
PIPE:
Select the discharge pipe diameter to be equal to
or larger than the diameter of the discharge noz
-
zle. For more details, refer to the table below.
DISCHARGE VALVES:
Install a non-return valve and a gate valve in the
discharge pipe. Install the non-return valve
between the gate valve and the pump. If an
increaser is used in the discharge pipe, install the
increaser between the pump nozzle and the non-
return valve. If the drive fails, the non-return valve
protects the pump against a reverse flow of the
fluid.
