7.1 Commissioning/Start-up
7.1.1 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, the pressure booster system will start neither in manual nor in test run
mode. 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.
7.1.2 Dry running protection
Pressure booster systems can be factory-equipped with pressure switches as dry
running protection devices. Such dry running protection devices will be factory-set to
the inlet pressure values specified in the purchase order.
If the factory settings should not match the site data, set the start and stop pressure
as described in the operating manual of the pressure switch.

7.1.3 Commissioning/start-up of pressure booster system
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.
Commissioning should be carried out by specialist KSB staff.
