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 control panels are on the chassis of the pump 

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.
