Accumulator
The accumulator serves to compensate for
pressure losses in the piping system downstream
of the pressure booster system which may be
caused by the consumption of small quantities of
water. As a result, the frequency of starts of the
pressure booster system is minimised.
Automatic mode
The pump is started and stopped as a function of
pressure or via a contact at the wall hydrant.
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Dry running protection
Dry running protection devices prevent the pump
from being operated without the fluid to be
handled, which would result in pump damage.
Manual mode
In manual mode, the pressure booster system is
operated directly on mains power, independently
of the control unit.

5 Control unit 6 Shut-off valve
Design The fully automatic pressure booster system is equipped with a non-self-priming
vertical high-pressure pump (1) for pumping the fluid handled to the consumer
installations in the set pressure range.
Function
Automatic mode
The pump is started and stopped as a function of pressure by a fully automatic
control unit. If the pressure drops below the set start-up pressure pstart, the pump is
started up via the pressure switch.
When consumption decreases again, the pump is stopped as a function of pressure
after the set after-run period (up to 3 minutes).
The pressure booster system can also be controlled via External ON/OFF signals,
independently of the pressure switch.
Function
Manual mode
A manual-0-automatic selector switch is provided at the switchgear and controlgear
assembly. When the switch is set to "manual", the pump operates directly on mains
power, independently of the automatic system (pressure switch or External ON/OFF).
NOTE
Continuous manual mode is reserved exclusively for emergencies!
Continuous operation of the pressure booster system in manual mode may result in
waste of energy and water.
In manual mode, a minimum flow (see table below) is essential to prevent the fluid
handled and the pump from overheating when no water is consumed at the
consumer installations.

5 Installation at Site
5.1 Installation
Install pressure booster systems either in the technical equipment room or in a well-
ventilated, frost-free, lockable room used for no other purpose. No harmful gases are
allowed to enter the place of installation. An adequately sized floor drain (leading to
a sewer or equivalent) must be provided.
The pressure booster system is designed for a maximum ambient temperature of 0°C
to +40°C at a relative humidity of 50%.
NOTE
Do not install pressure booster systems next to sleeping or living quarters.
If expansion joints (KSB accessory) are used for damping vibrations, their fatigue
strength (endurance limit) must be given due consideration. Expansion joints must be
installed to allow quick and easy replacement.
5.2 Checks to be carried out prior to installation
Place of installation
WARNING
Installation on mounting surfaces which are unsecured and cannot support the
load
Personal injury and damage to property!
▷Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class X0 to EN206-1.
▷The mounting surface must have set and must be completely horizontal and
even.
▷Observe the weights indicated.
NOTE
The anti-vibration mounts of the pressure booster system provide adequate
insulation against solid-borne noise.
1. Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing.
5.3 Installing the pressure booster system
WARNING
Top-heavy pressure booster system
Risk of personal injury by pressure booster system tilting!
▷Pressure booster systems awaiting final installation must be secured against
tipping over.
▷Firmly anchor the pressure booster system.
Remove all packaging before installing the pressure booster system. Connect the
pressure booster system's inlet line and discharge line to the corresponding site
distribution lines.

5 Installation at Site
17 of 36
Hya-Solo D
NOTE
In order to avoid transmission of piping forces onto the pressure booster system
and transmission of solid-borne noise, we recommend installing length-limited
expansion joints.
Allow sufficient space for maintenance and repair work.
üAll structural work required has been checked.
üThe dimensions of the concrete foundation are correct, and the concrete has set
firmly.
1. Mark out the anchoring holes on the floor as shown in the outline drawing.
2. Drill the holes (max. diameter: 12mm).
3. Insert plug fixings of appropriate size.
4. Set the pressure booster system down in its correct installation position.
5. Use suitable bolts to firmly anchor the pressure booster system.
5.4 Installing the piping
Make sure that piping is installed without transmitting any stresses or strains. The use
of length-limited expansion joints (see accessories) is recommended.
CAUTION
Air pockets in suction line
Pressure booster system cannot prime!
▷Lay piping with a continuously rising slope (as shown).
Suction lift operation
Incorrect Correct
NOTE
For suction lift operation install suitable swing check valves at the suction line ends
which are submerged in the fluid handled. Take into account the head losses
caused by these swing check valves.
Do not exceed the maximum suction lift of the pumps.
5.4.1 Fitting an expansion joint
DANGER
Sparks and radiant heat
Fire hazard!
▷Take suitable precautions to protect the expansion joint if any welding work is
carried out nearby.

5 Installation at Site
18 of 36 Hya-Solo D
CAUTION
Leaking expansion joint
Flooding of installation room!
▷Regularly check for cracks or blisters, exposed fabric or other defects.
üThe expansion joint has a length limiter with solid-borne sound insulation so as
to be able to absorb reaction forces.
1. Install the expansion joint in the piping free of twist or distortion. Never use the
expansion joint to compensate for misalignment or mismatch of the piping.
2. Tighten the bolts evenly and crosswise during assembly. The ends of the bolts
must not protrude from the flange.
3. Do not apply paint to the expansion joint. Protect it from any contact with oil.
4. The position of the expansion joint within the pressure booster system must
allow easy access and inspection and it must, therefore, not be insulated along
with the piping.
5. Expansion joints are subject to wear.
5.4.2 Installing a pressure reducer
NOTE
A pipe length of approximately 600 mm must be provided on the inlet side to
accommodate a pressure reducer, if necessary.
NOTE
A pressure reducer must be installed
- if the inlet pressure fluctuation is too high for the pressure booster system to
operate as intended or
- if the total pressure (inlet pressure plus shut-off head) of the pressure booster
system exceeds the design pressure.
The maximum pump discharge pressure at zero flow point is reached in manual
mode.
A minimum pressure gradient of 5 metres is required for the pressure reducer to
fulfill its function. The pressure downstream of the pressure reducer (downstream
pressure) is the basic parameter for determining the pump head.
For example:
The inlet pressure fluctuates between 4 and 8 bar. A pressure reducer is needed
upstream of the pressure booster system on the inlet side.
Min. inlet pressure (pinl)=4bar
Min. pressure gradient=0.5bar
Downstream pressure=3.5bar.
5.5 Installing unpressurised inlet tanks
Installation and location of an unpressurised inlet tank together with the pressure
booster system are governed by the same rules applicable to the pressure booster
system.
Install the closed PE inlet tank (under atmospheric pressure) available as a KSB
accessory as described in the installation instructions supplied with the tank.
CAUTION
Contamination in the pressure booster system
Damage to the pumps!
▷Clean the tank before filling it.

5 Installation at Site
19 of 36
Hya-Solo D
The tank must be connected mechanically and electrically to the pressure booster
system prior to commissioning of the system.
5.6 Fitting the dry running protection device
Install the dry running protection device supplied together with the pressure booster
system as a separate, non-fitted accessory, or supplied at a later date for retrofitting,
in accordance with its operating instructions and connect it to the switchgear and
controlgear assembly.
The switchgear and controlgear assembly is provided with the requisite digital input.
The cut-out delay can be set at the time relay within a range from 5 to 100 seconds.
The factory setting is approx.10seconds.
5.7 Electrical connection
DANGER
Electrical connection work by unqualified personnel
Danger of death from electric shock!
▷Always have the electrical connections installed by a trained and qualified
electrician.
▷Observe regulations IEC60364.
WARNING

6.1 Commissioning/Start-up
6.1.1 Prerequisites for commissioning/start-up
Before commissioning/start-up of the pressure booster system make sure that the
following requirements are met:
▪The pressure booster system has been properly connected to the electric power
supply and is equipped with all protection devices.
▪All relevant VDE standards and/or regulations applicable in the country of use are
complied with.
▪The dry running protection device has been installed.
CAUTION
Dry running of pump
Damage to the pump/pressure booster system!
▷If no dry running protection device is connected when commissioning takes
place, pressure booster systems in manual or test run mode will be stopped
automatically after approx. 10 seconds. If the dry running protection terminal is
disabled by means of a bridge, the operator shall assume responsibility for any
dry running that might occur.
NOTE
The competent authorities must be informed in due time prior to commissioning/
test running the system.
6.1.2 Commissioning/start-up of pressure booster system
Commissioning should be carried out by specialist KSB staff.
NOTE
The pressure booster systems undergo hydraulic testing with water at the factory
and are drained carefully before shipment. However, for technical reasons the
presence of some residual water is unavoidable.
The hydraulic connections are closed in as-supplied condition. They must only be
opened immediately before installation.
Refer to EN806 before commissioning/starting up the pressure booster system.
After an extended pre-installation period, in particular, flushing or even
professional disinfection is recommended. For extensive or branched piping systems
the pressure booster system should preferably be flushed either before installation,
or flushing should be restricted to a limited area.
CAUTION
Foreign matter in the piping
Damage to the pump/pressure booster system!
▷Before commissioning/starting (or even test running) the pressure booster
system, make sure that there is no foreign matter in the pressure booster
system or piping.
