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 Setting the dry running protection device
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.

▷
Before commissioning/starting (or even test running) the pressure booster
system, make sure that there is no foreign matter in the pressure booster system
or piping.
NOTE
Commissioning of the pressure booster system - even test running - shall only be carried
out in full compliance with all pertinent VDE (German Association of Electrical Engineers)
regulations.
