01. Introduction
Read this manual carefully before installing and using
the product. Improper use of the product can cause
personal injury and damage to property and may void
the warranty. When ordering spare parts use page 15.
02. Use of Booster Set
Water is usually delivered by public supply systems
and the pressure is generally sufficient for the proper
operation of the user's water and sanitary equipment.
When this pressure is not sufficient, booster sets are
installed to increase water pressure and ensure an
acceptable minimum value at the furthest points.
Therefore, the water supply to a building, group of
buildings or to a system, in general, can be considered
satisfactory when all the user points can deliver the
required quantity of water.
03. Schematic Booster Set Connection
Method
Water is supplied by installing a water storage tank
between the users off take and booster set. (Fig.1)
04. Handling
When the booster unit is delivered, check that it has not
been damaged during shipping. Promptly inform our
nearest dealer, if necessary. Do not use the eyebolts,
expansion tanks, inlet and discharge manifolds etc., as
they are not designed to bear the weight of the booster
set. The product must be handled with care using
suitable hoisting equipment; accidents can damage
the product without being necessarily visible on the
outside; hoisting non-packed products by securely
putting them into a sling from the main chassis. Please,
put the unit on to the floor, gently.
05. Applications
The booster sets are suitable for water handling
systems in the civil, industrial and agricultural sectors,
for pressure boosting water supply for small houses,
buildings, factories, industrial plants, holiday villages
and water treatment plants.
They are not suitable for;
• Liquids containing abrasives
• Liquid with solidand fibrous substances - Flammable
and explosive liquids
06. Installation
For booster unit lifting and moving sling it safely. The
unit should not be exposed to the weather or freezing
temperatures. Make sure that there are no obstacles,
preventing normal flow of the cooling air moved by
the motor fan. The booster set must be put on to a
horizontal concrete base or equivalent structure by the
4 pieces of rubber supports, which are provided with
the unit. The bigger industrial models must be firmly
secured by means of appropriate bolts to a concrete
base.
07. Suction and Discharge Pipes
Use pipes suitable for the maximum booster set
working pressure. The suction pipe must be perfectly
sealed and of suitable size for the suction conditions
(suction pipe Ø ≥min. inlet manifold Ø of the booster
set or pump). When the liquid level is lower than the
booster set, a foot valve must be fitted at the end of the
suction pipe (see Fig.2) (Fig.3)

08. Start-Up
Expansion vessels are delivered  at 4 bars, with pre-
charged factory settings. The pre-charged pressure in
the tank must be adjusted before start-up so that it will
be slightly below the cut-in ( starting ) pressure of the
pump(s). Practical recommended pressure level can
be determined as %10 lower than the cut-in ( starting
) pressure of tank.
08.1 Electrical Connection
The booster sets use single or three-phase motors
sized and powered according to European standards.
The booster set must be connected by a qualified
electrician in compliance with current local electrical
regulations. Ensure that the mains voltage corresponds
to the voltage specified on the booster set rating plate
Before start-up, the grounding of the booster shall be
maintained. The current leakage relay (30 mA) shall
be installed in the pump controller before the energy
supply.
a) Single pump booster sets are supplied as standard
with a thermal magnetic protection switch and float
switch for protection against dry running.
b) Multi-pump booster sets are supplied with control
panels with, main on-off switch, fuse carrier and fuses,
power contactors, overload relays, phase protection
relays over 7,5 KW, electronic change over control
board, float switch for protection against dry running,
automatic-manual switch for each pump power on,
running, reset and no water indicating (warning) lights.
09. Pre-Operation Test
Fill the suction pipe and the pumps with water to test
before the actual operation. Assemble the pipes as
shown in figures 4 and 5 and connect the float switch.

Close the discharge valve, remove the fill/bleed plug and
open the suction valve until the water flows out of the fill/
bleed plug. Then close the plug.
11. Liquid Level Lower Than the Pump
(Negative Suction)
Close the discharge valve, remove the fill/bleed plug
and by means of a funnel fill the water, close the plug.
Note : Adjust the float switch according to the size of
the tank. (Page 9)
12. Checking the Rotation Three-Phase
Motors
After connecting and filling, start the pump with the
discharge valve closed and check that the rotation
direction is correct (shown on the coupling and the
motor) through the coupling protection or fan cover. If
the direction of rotation is not correct, stop the motor,
disconnect from the mains and invert two wires on the
terminal board. B
13. Operation
Start up the booster set with the discharge (delivery) gate
valve closed and fallow pump or pumps reaching to the
switched-off pressure of the unit from the manometer.
Then open the service tap and check the system pressure
is dropping and the pump or the pumps running at
the starting pressure. If everything is okay, open all the
gate valves in the delivery line and let the system under
booster-set pressure.
14. Operations Description
14.1 Example for two-pump sets
The starting and stopping of the pumps are determined
by the pressure values set on the pressure switches.
Each pressure switch is connected to a single pump
with a cyclic pump change over. The differential
pressure is the pressure difference between starting
pressure and switch-off pressure. It is set at the same
value for both pumps.Figure 6 shows the operating
mode with the pumps curves
On demand, water is drawn from the tank
• When the pressure drops to the P1 value the first
pump starts.
• If the water consumption increases and the
pressure drops to the P2 value, the second pump
starts.
• When consumption reduces and the pressure
increases until it reaches the P2s value, one of the
pumps is switched off.
• If consumption keeps reducing, the pump charges
the tank and stops at the P1s value.

The control panel of a fire fighting booster is different
than the panel of a regular booster. Fire fighting
boosters are designed to work continuously during
a fire. Due to the law, these boosters do not include
thermal protection protecting the electrical engine
against fire.
Fire fighting boosters run only during fire. Thus,
there is a weekly test program aiming to minimize
the possible failures arising from long-term stand-by
and to detect and intervene to any available failure.
Fire fighting fighting booster works for a set period
of time automatically on a set date and time, and
stop. By ensuring the pumps operate one at a time
during the time set on the weekly test program, all
the pumps are operated in order.
If the water level falls below the minimum level in the
water tank, the device will not be able to supply the
required pressure and falls down to the calibration
set pressure (a value just below the operating
pressure). At this point, an audio and visual alarm
is activated. Thanks to the electronic circuit. If the
system demands water from the system during the
weekly test program, the test ends and the booster
starts working regularly.
15.2 Installation
• Install the fire fighting pump in a humid-free
environment without the risk of frost and
explosion, and good ventilation.
• To keep the temperature constantly above +4 °C
in the booster room or the booster station, the
appropriate environment and the tools should
be provided.
• The rooms should be large enough to allow
comfortable entry and exit.
• If the chamber is below the surface level, stairs
allowing easy entry and exit should be built.
(Because it is very important to intervene to the
failures in cases of emergency.)
• The room should be well illuminated and the
room should have a sufficient number of plugs.
• The fire fighting booster should be placed near
the water tank or cistern as close as possible. It
is required for the suction pipe to be short and
its diameter to be equal to or larger than the
diameter of the suction pump, and space should
ensure that the assembly will be made using a
minimum amount of curves or brackets.
• Pipe connections (collectors,suction line, delivery
line) should be arranged in a way that their inlets
and outlets do not prevent accessing the parts
required to be accessed during emergencies
and the control panels.,
• While placing the fire fighting boosters, it should
be considered that the engine and/or the pump
group may be required to be disassembled
and taken out of the room. (Pipe and collector
connections should not prevent dismounting
and removing the pump and/or engine that are
the other boiler room equipments.)
• The floor should be inclined enough to allow
water drainage. If the group chamber is below
the surface level, the accumulated water should
be discharged using submerged pump and the
submerged pump should be backed up.
• If there is a risk of flood in the chamber, electrical
control panels should be mounted as high as
possible. If required, it should be carried to a
section where there is no such risk.
• If the controlpanels are onthechassis of thepump
group, it should be ensured during assembly that
the control panel is easily accessible and its cover
is easily openable (for repair and maintenance).
• If the control panels are separate from the pump
group, it should be ensured during assembly
that the control panel is easily accessible and the
front panel is directly seen when entered into the
room.
• Control panels should be grounded.
16. Jockey Pump in a Booster Unit
The jockey pump in a booster set generally to
maintain the small amount of water demands in
death hours of a day instead of running the main
pump in a huge plant.
17. Maintenance
The booster sets do not require specific inspections
at regular intervals. As a precaution, however, we
recommend that you carry out some or all of the
following checks at varying intervals depending on
the operating conditions;
• Leaks
• Thermal protector activation
• No. of starts per hour
• Noisy operation
If any malfunctions are found, refer to the next
section for possible causes and remedies, Check
membrane tank air pressure regularly every 6
months (page 7). The pump does not require any
scheduled routine maintenance. It may require
extraordinary maintenance which is generally
cleaning the liquid end or replacing the mechanical
seal or other worn parts. In this case, please refer to
the pages 12 - 25.
