SPU Operating and Maintenance Manual
P31000 D
3. General SPU description
3.1 Unit description
The HI-FOG Sprinkler Pump Unit (SPU) is designed to supply
high-pressure water to a HI-FOG water mist distribution system used
for fire protection. It is used with single-fluid, single-pipe type
HI-FOG sprinkler systems that use water, in the form of a fine
mist, as the fire suppressant.
The HI-FOG Boosted Sprinkler Pump Unit (BSPU) has similar
functionality as the standard SPU but it provides larger flow per
one motor. It is typically used in marine applications (machinery
spaces).
3.1.1 Main parts
The SPU has the following main parts:
One or more pump modules (the number depends on the SPU
installed, refer to the system specifications).
Each pump module has one 3-phase electric motor, two plunger
pumps and two unloaders.
An electric control and monitoring system (relay)
A break-water tank
NOTICE: Units may also be supplied without a break-water
tank.
A separator (optional) and filter in the inlet from the water
feeding system
A pneumatic stand-by pump
There can be either one or two power supplies to the SPU. If the
system includes two power supplies, the switching between them is
done automatically.
A feed pump or hydrophore supplies fresh water to the SPU. In
addition to the fresh water inlet the SPU may be connected to a
fire main or another water source for redundancy.
BSPU has the same basic components as the standard SPU. There
are some small differences, for example BSPU has suction hoses from
tank to pumps whereas SPU has pipes. In addition, BSPU has a wider
frame than SPU.

SPU Operating and Maintenance Manual
P31000 D
3.2 Operating description
Stand-by mode = Normal mode when the system is on. In normal use
the system must always be in the stand-by mode.
Operating mode = The system is activated.
Stabilisation mode = The system is returning from activation to
stand-by mode.
Off = The system is shut down for maintenance or repair.
A pressure of 25 bar (or other system specific set value) is
maintained in the system when it is in the stand-by mode.
A fire causes the heat-sensitive bulbs on one or more sprinklers
to break. Alternatively, section valves open and water starts to
flow from the released spray heads. The flow monitor detects the
flow and starts the SPU. A pressure switch starts the SPU if the
flow monitor malfunctions. You can also start the SPU manually,
either locally by turning the start switch(es) on the starter
cabinet, or remotely by sending a start signal to the starter
cabinet.
When the SPU is activated, the pump modules automatically start
in sequence. A few seconds delay between each start reduces
electric peak loads. If the flow of water required is less than the
output of the unit, the unloader valves open and route extra water
back to the break tank. High-pressure water is now fed to the
HI-FOG system forming a fire suppression mist.
After the SPU has been stopped it must be reset. The
stabilisation phase takes a few minutes, during which the system
pressure drops to the stand-by level and then the unit returns to
the stand-by mode.
-
15Marioff Corporation Oy P31000 D
4. Operating instructions
4.1 System in stand-by mode
In normal use the system must be in the stand-by mode. The
system is in the stand-by mode when:
the SPU is connected to the electric supply and the main power
switch is on
working air is supplied to the stand-by pump and the pump is
operational
the system pressure is within the set limits
the control system is operational
the piping is sound and tight (see Marioff Installation manuals
P32010 and DOC0004462)
4.2 Start
4.2.1 Automatic start
The SPU will automatically start to operate if it detects a
water flow and/or if the water pressure drops below a preset value
(typically 17 bar) for more than preset time (typically 10 - 20
seconds) (depending on the system size).
The redundant motor, if supplied, will automatically start if
one of the motors does not start or stops operating.
To stop the unit press and hold the Reset button for one (1)
second. Make sure that there is no fire before you stop the unit.
If there is still flow in the system after the reset period the
unit will restart (see chapter 4.4). Isolate the sections where
there is flow.
4.2.2 Manual start - remote
Press the Emergency start button on the remote control panel (if
provided) to start the SPU. Press the Emergency start button a
second time to stop the pump.
You must reset the unit after this. Refer to chapter 4.4.
4.2.3 Manual start - local
Set the pump activation switches in the pump unit control
cabinet to the 1 position to switch the pumps on.
To stop the pumps, set the switches to A position. You must
reset the pumps after this. Refer to chapter 4.4.
-
16 Marioff Corporation Oy
SPU Operating and Maintenance Manual
P31000 D
4.3 Pump unit in operation
When the pump unit has received a start signal it will maintain
the required pressure and flow in the system until a reset signal
is given or the pump runs out of water.
The low level switch in the break tank prevents the unit from
starting when there is not enough water, or stops the motors to
prevent them from running dry. When the redundancy source of water
(if applicable) has been connected and/or the break tank has been
refilled, the pumps will restart automatically.
If the HI-FOG activated mode is on and the pressure drops below
a preset value (typically 30 bar) for preset time (typically 15
seconds), or if there is a power cut, or if the motors cannot be
started for some other reason, a signal is automatically given to
release the water accumulator unit (if fitted).
4.4 System stop and reset
Step 1. Before you stop the unit, make sure that there is no
fire.
Step 2. Make sure that any released sprinklers/spray heads are
isolated and the section valves are closed so that there is no flow
into the HI-FOG system.
Step 3. Press and hold down for one (1) second the Reset button
on the pump unit or, if fitted, on the release or mimic panels.
The pump motors stop (if started automatically), the
stabilisation valve opens (decreasing the system pressure) and the
alarms clear.
NOTICE! Starting the pump with the pump activation switches will
override all other protection. Before carrying out a local manual
start, check that no fault alarms are on.
-
17Marioff Corporation Oy P31000 D
The stabilisation valve will close when the pressure in the
system drops to a preset value (typically 22 bar). After that, the
stand-by pump in the pump unit automatically increases the pressure
in the system to the stand-by pressure (typically 25 bar). Restart
is prevented during the stabilisation period. When the reset phase
is completed the pump unit automatically switches to the stand-by
mode.
You can also stop the water discharge from the SPU by closing
the ball valve located on the unit, but this is only recommended in
the case of unintentional release. This action will not stop the
motors.
Standard vessel systems will not reset properly unless the
system pressure has reached 130 bar. The pump unit must be run
until the pressure has risen above this point before resetting the
system by pressing the Reset button for one second.
Reset after a Manual emergency start (Manual start -
remote):
Step 1. To shut down the pump, press the same Emergency start
button that was used to start the system.
Step 2. Run the pump unit until the system pressure reaches 130
bar, after which you can reset the system by pressing the Reset
button for one second.
4.5 Clearing up after system operation
If sea water or a similar redundancy source was used, you must
flush the complete system with fresh water.
Step 1. Empty the break water tank of redundancy water via the
drain valve.
Step 2. Manually run the pump for a period long enough to remove
all the redundancy water from the pump unit, the break water tank
and/or the system piping.
Step 3. Change the water filter cartridge.

5.2 Inspection and maintenance procedures
This chapter describes how to carry out the inspections and
maintenance listed in the above table.
Treat as urgent, the notification of any factors liable to have
a detrimental effect on the performance of the pump unit or the
HI-FOG system.
5.2.1 Check all valve positions
In stand-by and operating modes the valves must be in the
following positions.
Open valves
outlet valve to the sprinkler system
fresh water supply valve
air inlet to the stand-by pump
Closed valves
test valve
sea-water / redundancy water valve
drain valve
5.2.2 Check the stand-by pressure and pump
Check that the stand-by pressure in the system is set to the
correct level (25 bar, if not otherwise stated) and ensure the
stand-by pump does not start running too often (if it does it
indicates that there is leakage in the system). A faulty stand-by
pump must be replaced with a new one.
For maintenance and overhaul refer to the manufacturers
operating and maintenance instructions.
5.2.3 Check electric supply, test lamps
Make sure that the SPU is receiving power.
Press the Lamp test button in the starter cabinet. All signal
lights in the starter cabinet should be lit. Change any faulty
light bulbs.
5.2.4 Visually inspect the pump unit and its fittings
Check that there is no water or air leaking from the system.
-
20 Marioff Corporation Oy
SPU Operating and Maintenance Manual
P31000 D
Check that all fittings are tight. Report all abnormal wear and
tear, damage, etc.
5.2.5 Check oil level of the pumps
The optimal oil level is at the mid-level of the sight glass. If
it is below this level, add more oil. See figure below.
The oil color should be clear golden brown. If the oil is dirty,
cloudy or grey when the unit is in the stand-by mode, change the
oil.
See the manufacturers pump operating instructions. See also
examples of recommended pump oil types in chapter Change pump oil
(every 2 years or 200 hours) on page 25.
5.2.6 Check drive chains and flexible coupling
The drive chains are self-lubricated, which means that they do
not need to be greased. To indicate this, there is a notification
sticker attached to the gearbox with the following text:
Notice! Do not use grease. This roller chain is
self-lubricated.
NOTICE! The oil appears cloudy when the unit is in the operation
mode.
NOTICE! Switch the unit off before checking the drive chains and
coupling. Turn the main switch off and secure it before removing
the cover.
-
21Marioff Corporation Oy P31000 D
However, if the drive chains are not maintenance-free (in older
pump units) and there is no notification sticker, the drive chains
must be well greased. If the chain is dry or rusty, grease the
chain using Shell Gadus S3 Wirerope T or an equivalent
molybdenum-graphite based grease with heat resistance up to +200C
and good adhesion capability.
Check also the condition of the flexible couplings. A slight
amount of wear is normal - if any signs of excessive wearing are
shown, change the coupling.
The chain and coupling can be changed by removing the pump
module (make sure that the pump unit is off before starting this
job). Four items of Marioff tool M12080 are needed. See Technical
data sheet TE1002 Standard HI-FOG SPU Gearbox chain and coupling
change.
5.2.7 Check air pressure regulator and empty water lock
Check for leakages and make sure that the stand-by pressure is
maintained at 25 bar (or other system specific set value).

5.2.9 Test run the unit
Step 1. Start the pump unit locally, remotely or
automatically.
Vary the way of starting occasionally to ensure that all the
starting modes work.
When testing locally, the pressure start is tested by closing
the air supply to the stand-by pump and fully opening the test
valve. The flow switch start is tested by slowly opening the test
valve so the pressure does not drop below 17 bar (or the set
value).
Step 2. Make sure that the unit starts to supply water at full
working pressure after a short delay.
Step 3. Make sure that all motors and pumps are running (except
the redundancy module, if supplied).
Step 4. If the redundancy module is supplied, test it by opening
the control fuse (F x.1) of one of the running motors.
Step 5. Reset the unit after testing by pressing the Reset
button (close test valve and open outlet valve if
opened/closed).
Step 6. Check that the pressure in the system returns to the 25
bar stand-by pressure after a few minutes.
Step 7. Check that the whole system is reset and
operational.
5.2.10 Check pump unit batteries and charger
Ensure the charger output voltage is 27.3 - 27.7 V at the
battery. Check the battery capacity with a suitable charge
condition meter.
The batteries must be replaced every five (5) years, or more
often if the battery is faulty, or the unit is subjected to
vibration, large temperature variations or other severe
environmental conditions. Note that especially high ambient
temperature reduces the battery life time.
NOTICE! Starting the pump with the manual switches on the
starter cabinet will override all protections. Make sure that there
is water and that no fault alarms are on.

6. Troubleshooting
This chapter lists the possible fault situations and their
remedies. If the problem you are facing is not listed here, contact
Marioff immediately.
When contacting Marioff in troubleshooting situations, have the
following information available:
the project number of the installed system
the serial number of the pump unit
detailed description of the fault situation (what was done
before the fault situation occured and what happened during the
fault situation)
6.1 General faults
This chapter lists the possible general SPU faults.
6.1.1 Unit will not start
Possible reason: No electric supply.
Solution: Connect supply. Check if the main fuses in the main
switchboard have blown. Check if the starter cabinet main switch is
open or the main circuit breaker has released.
Possible reason: No control voltage.
Solution: Connect supply. Check control voltage fuse of
auxiliary voltage transformer.
Possible reason: No water.
Solution: Ensure feed water availability.
Possible reason: Stabilisation phase is on (Pump unit reset
light on the starter cabinet is on).
Solution: Wait for completion of stabilisation phase or start
the pump unit manually.
6.1.2 Unit will not stop
Possible reason: Pressure has not exceeded 130 bar in the system
or/and the emergency start is still activated.
Solution: Run the unit until the pressure reaches 130 bar and
then reset the unit (see chapter 4.4.) or/and deactivate the
emergency start.
6.1.3 Unit starts unintentionally
Possible reason: Pressure switch is faulty or incorrectly
adjusted.
-
28 Marioff Corporation Oy
SPU Operating and Maintenance Manual
P31000 D
Solution: Adjust or replace pressure switch (must be correctly
adjusted, contact Marioff).
Possible reason: Flow switch is faulty or incorrectly
adjusted.
Solution: Adjust or replace flow switch (must be correctly
adjusted, contact Marioff).
Possible reason: Small leakage in the system.
Solution: Ensure system is tight.
Possible reason: False start signal.
Solution: Check system wiring and signals.
Possible reason: System pressure drops due to system leakage or
stand-by pump problem.
Solution: Ensure system is tight. Check air supply to stand-by
pump. Check stand-by pump (refer to manufacturers instructions) and
replace if faulty.
6.1.4 Water accumulators released unintentionally (if
fitted)
Possible reason: Operational fault caused by
opening main switch (control voltage still on, start signal
active, pressure decreasing --> water accumulator released)
test valve kept open so that pressure stays below 30 bar (or set
value) for more than 15 seconds (or set value)
Solution: The water accumulator will release if the start signal
is on and the pressure stays below 30 bar (or set value) for more
than 15 seconds (or set value). Before testing or servicing the
unit the water accumulator solenoid valve should be
disconnected.
Possible reason: Pressure switch faulty or incorrectly
adjusted.
Solution: Adjust or replace pressure switch (must be correctly
adjusted, contact Marioff).
6.1.5 Stabilisation phase not completed
The stabilisation will not start before the system pressure has
reached 130 bar. The pump unit must be run until the pressure has
risen above 130 bar before resetting the system is possible.
Possible reason: Pressure switch faulty or incorrectly
adjusted.
Solution: Adjust or replace pressure switch (must be correctly
adjusted, contact Marioff).
Possible reason: Stabilisation valve is faulty.
Solution: Replace valve.
6.1.6 Stand-by pump striking frequently
Possible reason: Small leakage in the system.
-
29Marioff Corporation Oy P31000 D
Solution: Ensure system is tight.
Possible reason: Stand-by pump is faulty.
Solution: Replace stand-by pump.
Possible reason: Air trapped on the pump inlet side.
Solution: Bleed air from the bleeding pipe by opening the nut
and letting the air out of the pipe.
6.1.7 Fuses blown
Possible reason: Establish reason for disengaged fuses and
rectify.
Solution: If problem rectified or reason not found, reconnect.
If problem persists, contact Marioff.
6.2 Alarms
This chapter lists the SPU system alarms.
6.2.1 Nitrogen pressure low (if connected to water accumulator
unit)
Possible reason: Pressure in one or more nitrogen cylinders
below alarm set value.
Solution: Refill/replace nitrogen cylinder(s).
Possible reason: Alarm circuit cut.
Solution: Reconnect.
6.2.2 Battery charger fault
Possible reason: No power supply to the charger or unit.
Solution: Reconnect supply.
Possible reason: Charger is faulty.
Solution: Replace charger.
6.2.3 230VAC control voltage fault

6.2.4 Earth fault (24VDC)
Possible reason: + or - of the 24VDC control in contact with
ground.
Solution: Find the contact point (for example, by opening fuses
and disconnecting panels) that causes earth fault and rectify.
6.2.5 Circuit breaker released
Possible reason: Overload or short circuit in electric
coupling.
Solution: If problem rectified or reason not found, reconnect.
If problem persists, contact Marioff.
6.2.6 Out of water
Possible reason: Water in break tank below low level (or feed
water pressure low in unit without tank).
Solution: Make sure there is a feed water supply.
Possible reason: Tank low level switch faulty or stuck; cable
fault.
Solution: Rectify or replace.
NOTICE: If this happens in an emergency and it is certain that
all valves to fresh water supply are open, switch over to the
redundant water source (sea water or equivalent).
6.2.7 Pump unit fault
Possible reason: Common alarm given in combination with one of
the above.
Solution: See above.
6.2.8 Compressed air low pressure fault (if applicable)
Possible reason: Compressor fault.
Solution: Check compressor; replace if faulty. Check compressed
air supply. If supply in order, check pressure switch and
cables.
6.2.9 Inlet/Outlet valve closed (if applicable)
Possible reason: The valve is not fully open, thus it sets an
alarm.
Solution: Check that both valves are fully open.
6.2.10 Line voltage fault (if applicable)
This fault is a signal to a third-party system.
-
31Marioff Corporation Oy P31000 D
Possible reason: Main supply voltage fault.
Solution: Check the system for low voltage, excess voltage, or
asymmetric phases. Check phase monitor relay.
6.2.11 Other faults
Possible reason: Reason cannot be found.
Solution: Contact Marioff for assistance or advice.
Note that some faults are automatically remedied and the fault
information is lost. In some cases the faults are sent to a
third-party system before the automatic remedy takes place and
possibly the fault alarm is visible in the third-party system but
not in the SPU anymore. In those events the third-party system
needs to be checked according to the manufacturers
instructions.
