8.3 Commissioning
Before starting up the MPE 70 and the high-
pressure pump, make sure the following
requirements are met:
Slowly raise the pressure in the
system and set all pressure switches
to the correct limit and continually
check all connections.
• If pressure relief valve is present,
set pressure relief valve on both
low and high-pressure at the
maximum system pressure.
• Check high-pressure piping for
proper assembly and inspect for
external leakage for all connec-
tions. If there is no pressure relief
valve installed make sure the
brine concentrate valve is open
to allow pressure relief during
commissioning.
