6.1 Commissioning/Start-up
6.1.1 Prerequisites for commissioning/start-up
CAUTION
Pump set running dry
Damage to the pump set / fire-fighting system!
▷
Use a dry running protection device. 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 fire-fighting 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 owner or the owner's representative must have the system's readiness for
operation and connection conditions checked by the responsible authorities (e.g.
local water provider or the office for industrial safety and product safety).
▪
The dry running protection device has been installed. (
6.1.2 Priming and venting the fire-fighting system
CAUTION
Foreign matter in the piping
Damage to the pump set / fire-fighting system!
▷
Before commissioning/starting up or test running the fire-fighting system, make
sure that there is no foreign matter in the fire-fighting system or piping.
CAUTION
Operation without the fluid to be handled
Damage to the pump set!
▷
Prime the fire-fighting system with the fluid to be handled.
NOTE
Prior to delivery, the fire-fighting system is hydraulically tested with water and then
drained again. For technical reasons the presence of some residual water is
unavoidable.
Prior to commissioning/start-up observe EN 806. After prolonged standstill periods,
flushing or professional disinfection is recommended. For extensive or branched
piping systems flushing the fire-fighting system can be restricted to a limited area.
NOTE
Minor leakage of the mechanical seals during commissioning is normal and will
cease after a short period of operation.
