6.1.2 Priming and venting the pressure booster system
CAUTION
Foreign matter in the piping
Damage to the pump / pressure booster system!
Ø
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.
CAUTION
Operation without the fluid to be handled
Damage to the pump sets!
Ø Prime the pressure booster system with the fluid to be handled.
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 EN 806. 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.
NOTE
Minor leakage of the mechanical seals during commissioning is normal and will
cease after a short period of operation.
Have commissioning carried out by specialist DP staff.
