6.1 Commissioning/Start-up
6.1.1 Prerequisites for commissioning/start-up
CAUTION
Pump set running dry
Damage to the pump set/pressure booster system!
▷ Use dry running protection. 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.
Ensure that the following requirements are met prior to commissioning/start-up:
▪ 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. (ðSection5.5,Page22)
6.1.2 Dry running protection
Pressure booster systems are fitted with a dry running protection device.
A float switch whose volt-free contact closes the circuit in upper float position can be
connected to the control system as dry running protection. Follow the float switch
manufacturer's instructions on how to set the float switch levels.
6.1.3 Commissioning/start-up of pressure booster system
NOTE
Prior to its delivery, the pressure booster system will be tested hydraulically with
water and then drained again. For technical reasons the presence of some residual
water is unavoidable.
Prior to commissioning/start-up observe EN806. After prolonged standstill periods,
flushing or professional disinfection is recommended. For extensive or branched
piping systems, flushing the pressure booster system can be restricted to a limited
area.
Commissioning should be carried out by specialist KSB staff.
CAUTION
Foreign matter in the piping
Damage to the pump / pressure booster system!
▷ Before commissioning/starting up or functional check 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.
