Pump requirements
Pump actuation means that a pump starts up when a start signal is sent by a
pressure switch, from a wall hydrant (limit switch), by remote on/off, or from
the wire breakage and short circuit monitoring relays.
Automatic operating mode
The pump is switched on and off either by pressure control or by a contact
on the wall hydrant.
EN 1717
European standard that specifies technical regulations for potable water
installations.
DIN 14462
German standard that pertains to extinguishing water equipment and with
which fire extinguisher systems have to comply.
Membrane pressure vessel
The membrane pressure vessel is for compensating pressure drops in the
pipeline network behind the compact booster unit, that can occur because of
loss of minimal quantities.
That minimises the frequency of operation of the compact booster.
Noise expectancy values
The expected noise emission, stated here as sound pressure level (SPL) in
dB(A).

3.5 Mode of operation
3.5.1 Mode of automatic operation
The system is switched on and off by a pressure regulated electro-mecha-
nical control unit. If the preset pressure pE is not reached, the pump is acti-
vated via the pressure switch. If water consumption decreases, the pump
shuts off after a preset follow-up time (up to 10 minutes).
The system can be controlled by remote on/off independently of the pres-
sure switch (for example by switches in wall hydrants for fire extinguisher
systems). Pressure switch and remote on/off inputs are monitored for wire
breakage and short circuits. If wire breakage or a short circuit is detected,
the system is automatically turned on and the yellow indicator light signals a
malfunction.
In automatic mode, all systemsafety equipment (dry running protection,
motor protection) are disabled because pumping has the priority during
a fire. The motor is still monitored, but once the motor protection switch
has been activated, the motor remains unmonitored in the network and
an error message is displayed.
The required amount of water is fed into the system via the inlet valve. For
this purpose, the float valve on the potable water inlet opens and closes fully
automatically.
3.5.2 Mode of manual operation
Manual operation is also possible in addition to automatic mode as an
exception.
3.5.6 Mode of operation for refilling
Refilling is done automatically via a float valve. Water shortage and overflow
are indicated as an error by the switch cabinet.
Refilling has to be done with 25 m3/h (for design flow
18 m3/h) and with 50 m3/h (for design flow 36 m3/h and
48 m3/h) and system pressures of 1.5 bar (at 18 m3/h), 3.0 bar (at
36 m3/h) and 4.0 bar ( at 48 m3/h) and a maximum of 8 bar.
The flow rate has to be set by a throttle valve on the system. If refilling
works properly, the tank is filled up to just below the overflow hole in the
middle after the refilling valve is closed. The overflow with integrated si-
phon trap is designed corresponding to the refilling. The system opera-
tor is responsible for ensuring the drain outlet lines are sufficiently
dimensioned.
According to DIN 1988-600, the maximum flow rate in a single inlet line
to the extinguishing water transfer point may not exceed a calculated
flow rate of 5 m/s.
3.5.7 Mode of operation for flushing
Flushing of the potable water pipeline connected upstream can be activated
by setting the digital timer in the switching cabinet via the solenoid valve.
The flushing water is discharged though the integrated overflow. The flus-
hing time is estimated with respect to the required flushing volume (refer to
the following figure). For larger flushing volumes (more than 200 l), it can be
increased by 7 l (25 m3/h) and 14 l (50 m3/h) with each further second.
A manual/automatic switch for the pump is on the switch cabinet. In the posi-
tion Manual the pump is connected to the network, independent of the auto-
matic mode (pressure switch or remote on/off).
Manual operation is only for emergency!
Continuous operation of the system in manual mode can lead to exces-
sive water and energy consumption due to the bypass line.
To keep the pump and the pump medium from overheating during manaul
operation in the case of zero delivery, a minimum amount has to be pumped.
If not, the magnetic valve in the bypass is opened when the pump mantle
reaches a programmable temperature, in order to ensure that a minimum
amount of medium is pumped.

3.5.3 Mode of operation for testing
There is a digital timer in the switch cabinet with which testing is parame-
trised. In testing mode, the pump is connected to the network, independent
of the automatic mode (pressure switch or remote on/off).
3.5.4 Mode of operation for protection against dry running
Protection against dry running is active in the manual and testing modes, as
long as the pressure does not fall below the switch-on pressure pE or the
system is actuated by remote on/off, because the situation is interpreted as
a case of fire that has to be extinguished and for which the system safety
equipment has to be disabled. The connection for the dry running protection
is a digital input. If it is open, the control unit registers dry running and shuts
the system off after approx. 10s (default setting).
3.5.5 Mode of operation for temperature monitoring
There is a temperature monitor on the pump mantle that opens the magnetic
valve on in the bypass, if a programmable temperature is registered (default
90 °C) to protect the pump against overheating when operated without a
minimum amount discharge. Temperature monitoring is activated in the
automatic and manual modes.
Figure 5: Determining the flushing time
3.5.8 Mode of operation for separation of potable water
The Compact Booster Unit can be supplied with water exclusively by
sending a potential free message "potable water separation" to close the
supply of potable water to other consumers at a branch upstream from the
system. The message is sent with a time delay (default 30 s) when actuated
by pressure switch of remote on/off.
3.5.9 Mode of operation in the event of power loss
In the event that the mains power supply of the entire system fails standby is
no longer functional.

inspectorate). Before starting the system, the author has to certify that the
prerequisites for connection are fulfilled.
Before the system is connected to the mains power supply, the operator has
to read the relevant VDE regulations.
The electrical supply lines must only be installed by companies that are
authorised to do such work.
7. Start-up
Performance of tasks only by qualified personnel (see section 1.11).
7.1 Safety instructions for start-up
Warning
Danger from improper operation.
 Malfunctions
Before starting, the manual has to be read by the operator as
well as by the responsible technical/operating personnel and
has to be stored at the site of the compact booster unit at all
times.
Adhere to local safety and accident regulations when starting
the compact booster unit.
Damaged or improperly installed compact booster unit.
 Malfunctions
Check the compact booster unit for obvious signs of damage;
eliminate any defects immediately or alert the supervising
personnel. The compact booster unit may only be operated in
perfect working order.
Inform yourself sufficiently about
•the equipment of the compact booster unit
•the functionality of the compact booster unit
•the close surroundings of the compact booster unit
•the measures to be taken in an emergency
7.2 Start-up requirements
Caution
Dry running pump
 Damage to the pump/system!
If water shortage occurs during start-up, in manual or testing
mode, the compact booster unit shuts off after approx. 10s. If
the dry running protection is deactivated, then the operator
takes responsibility in the case of dry running.
The responsible authorities have to be informed before start-up and be-
fore testing.
Before start-up of the compact booster unit, the following points have to be
ensured:
•The compact booster unit has to be connected to all protective equipment
according to the regulations.
•The relevant VDE and country-specific regulations have to be adhered to
and fulfilled.
•The buffer tank has to be full of water.
•The refilling has to function properly.
•Flange connections have to be checked if they are fastenedtightly.
•Pipe fittings between pump and pipeline have to be tightened.
•In and output openings for air-cooling of the motor are free.
•The precharge pressure of the membrane pressure vessel ischecked.
•All shut-off valves in the system are open.
7.3 Initial operation
The initial start-up should be performed by Resideo technical staff.
Caution
The pipeline must be free of residue
 Danger of damaging the pump/compact booster unit!
Before start-up (and testing) make sure that pipelines and
compact booster unit are free of residues.
Caution

No pressure on the output side
 Pump starts when main switch is turned on!
During start-up and also during automatic mode, the pump
starts as soon as the main switch is turned on, because the
system receives astart command from the pressure switchdue
to the lack of pressure on the output side. This is noteven
prevented if the motor protection switch is also activated.
The start-up, or testing mode, of the compact booster unit may only be
initiated if all VDE regulations have been fulfilled.
Floating ring seals may briefly show signs of leakage during start-up,
but no longer after a short period of operation.
The protection against dry running is only active in manual and testing
modes.
1. Connect electrical circuit on-site.
2. Main switch set to 0 and manual/automatic switch to automatic.
3. Connect water supply for refilling on-site.
4. Open or loosen the ventilation screws on the pump (refer to operating/
assembly instructions).
5. Slowly open the shut-off valves on the input side and fill the system until
pump medium runs out of every ventilation borehole.
-To do so, loosen the setting screw to open the refilling valve and fill the
tank after connecting the system to the water supply.
-Set the amount of refilling water with the throttle valve. (refer to
Chapter7.3.1.2).
6. Close the ventilation screws, tighten pump ventilation lightly.
7. Set main switch to I.
8. Set system with manual/automatic switch to manual operation and
check in which direction the pump is rotating.
-The direction of rotation has to be the same as the direction shown by the
arrow on the motor. If it is rotating in the wrong direction, two phases of
the inlet have to be exchanged.
9. Set system with manual/automatic switch to automatic operation.
10. Slowly open the shut-off valve of the output and use the pressure gauge
to check if the system starts if the switch-on pressure is reached (refer to
Chapter 4.).
-If the switch-on pressure is set to the wrong value, it has to be changed
as described in the pressure switch manual.
11.Slowly close the shut-off valve of the output and use the pressure gauge
to check if the system shuts off when the switch-off pressure is reached
(refer to Chapter 4.).
-If the switch-off pressure is set to the wrong value, it has to be changed
as described in the instructions of the pressure switch.
-The follow-up time has to be set on the relay to the maximum number of
operating cycles that are permissible for the motor by turning the setting
screw until it reaches a value between 3 and 10 minutes. Up to 7.5kW =
20 cycles/hour, from 11 to 22kW = 10 cycles /ho, from 30kW = 6 cycles/
hour)
12.Let the pump run again with the output shut-off valve open, loosen the
ventilation screw and let the rest of the air out.
13.Close the ventilation screw tightly.
14.Check if the pump runssmoothly.
15. By closing the shut-off valve on the output line, check if the pump
reaches its maximum pumping head in the zero point.

7.3.1.2 Set the amount of refilling water with the throttle valve
For systems with a pump volume of 18m3/h, the amount of inlet water has to
be set to 25m3/h on the throttle valve as a function of the supply pressure.
For systems with a pump volume of 36m3/h, the amount of inlet water has to
be set to 50m3/h on the throttle valve as a function of the supply pressure
7.3.1.3 Setting the power-off delay
The power-off delay can be set to values from 5 to 100 s (refer to documen-
tation of cabinet).
7.3.1.4 Setting the rinsing duration
Flushing of the potable water pipeline connected upstream can be activated
by setting the digital timer in the switching cabinet via the solenoid valve.
The flushing water is discharged though the integrated overflow. The flus-
hing time is estimated with respect to the required flushing volume (refer to
the following figure). For larger flushing volumes (more than 200 l), it can be
increased by 7 l (25 m3/h) and 14 l (50 m3/h) with each furthersecond.

Danger
Filling wrong gas in expansion vessel
 Danger of poisoning!
Only fill the pressure pad with nitrogen.
Caution
Precharge pressure too high
 Danger of damaging the tank!
Observe the values as stated by the manufacturer of the tank
(refer to type label or the tank manual).
The precharge pressure for the pressure vessel should be set to a value that
is lower than the programmed switch-on pressure.
This setting can be made with a valve under the cover hoodon the top of the
tank.
Example: Precharge pressure 10% below the switch-on pressure
Precharge pressure of the membrane pressure vessel p = 0.9 x pE
pE = switch-on pressure of the compact booster unit
Recommendation
These are average values. Experiments conducted on tanks have shown
that the best storage volumes were achieved for pressures >3bar with a
factor of 0.9 and pressures of <3bar with a factor of 0.8.
Example:
pE = 5 bar: Precharge pressure 5 x 0.9 = 4.5 bar
pE = 2 bar: Precharge pressure 2 x 0.8 = 1.6 bar
