3. Description
Honeywell Compact Booster Unit - single pump CBU144 as a safety device
to separate potable water from category 5 fluids according to DIN EN 1717
for fire extinguisher applications acc. to DIN 14462 and DIN1988-600 with
free outlet type AB and a vertical high-pressure pump.
Fully automatic, fully wired Compact Booster Unit-single pump with modular
design comprising a single pump system and a buffer tank for the hygienic
separation of potable water and category 5 fluids according to DIN EN 1717,
on a common base frame. The modular design makes it possible to discon-
nect modules for installation in buildings with limited space. The system is
switched on and off regulated by pressure.

Intended use
The compact booster unit may only be operated in such areas as described
in the other applicable documents.
Non-intended operation of the compact booster unit can result in danger to
persons, systems, the surroundings and the environment.
• Operate the compact booster unit only if it is in perfect working condition.
• Do not operate the compact booster unit if it is only partially assembled.
• The compact booster unit may only be used to pump the medium as
described in the documentation of the respective version.
• Never operate the compact booster unit without pump medium.
• Observe the values for minimum pumping rates (avoiding damage
because of overheating, storage damage, ...).
• Observe the values for maximum pumping rates (to avoid damage due to
overheating, floating ring seal damage, cavitation damage, storage
damage, ...).
• Do not throttle the input of the compact booster unit (to avoid cavitation
damage).
• Other modes of operations, if not mentioned in the documentation, have
to be coordinated with the manufacturer.
3.2
Non-intended use
The compact booster unit is not designed for operation outside. Tempera-
ture, light and moisture can lead to malfunctions and damaging devices.
• Do not operate the compact booster unit outside.
• Operate the compact booster unit only as intended.
• Do not fill aggressive or flammable medium into the medium lines of the
system.
• No mechanical stress on housings (e.g. by depositing objects or as a
step).
• Do not perform any external modifications on the device housing. Do not
paint housing parts and screws!
• Do not disassemble the compact booster unit more than is necessary for
purposes of installation and maintenance.

Version
The Compact Booster Unit consists of the following modules, that can be
disassembled (for example for transport purposes).
• The single pump booster unit has a pump, a control unit, valves and
connected piping. The pressure switch and temperature sensor are
installed, wired and preset with standard default values in the factory.
• Buffer tank with inlet and flushing apparatus as well as level, overflow and
dry running monitor. The components are assembled and preset in the
factory. The electrical components are connected to the control unit of the
booster station with plug connections. Thus if required an electric separa-
tion can be made.
• A common base frame for the double pump booster unit and the buffer
tank that allows tranportation with a standard pallet hand forklift.The
pumps and base frame are equipped with vibration dampers.
