3. Description
Speed controlled compact booster unit with a vertical high-pressure pump as
a safety device to separate potable water from category 5 fluids according to
EN 1717 .
Fully automatic, fully wired Compact Booster Unit with modular design
comprising a single pump system and a buffer tank for the hygienic separa-
tion of potable water and category 5 fluids according to DIN EN 1717, on a
common base frame.
The modular design makes it possible to disconnect modules for installation
in buildings with limited space.
The system is switched on and off regulated by pressure, the flow rate is
controlled via frequency inverter..
Separation of systems as a means to protect potable water from being
contaminated by fluids of the category 5 according to EN 1717

3.1 Overview
The system comprises one multi-speed high-pressure rotary pump with inlet
and outlet shut-off valves. They can be locked with padlocks against
unauthorised closing. They make it possible to disassemble the pump or the
check valves without having to empty the pipeline system. The check valve
on the pumping side prevents liquid from backing up on the pump and
flowing backwards through it, and it relieves the floating ring seal.
The fully automatic Compact Booster Unit with compact design comprising:
• vertical high-pressure pump
• frequency converter adapted on the motor to ensure a constant supply
pressure to the points of consumption
construction and operation is according to DIN 1988,EN 1717 and EN
13077.

3.1.1 Installation type
• Fixed installation
3.2 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.
3.3 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.
