(MP) or 14 bar (LP) at the manometer (11)!
• Repeat the adjustment steps, if required. The
original drinking water amount may possibly
not quite be reached.
(3) The difference between pump and
concentrate pressure has increased
by more than _____ bar
• Read the values at the manometer for the
pump pressure (11) and for the concentrate
pressure (12), and determine the differential
pressure.
• Compare the differential pressure with the
value taken when starting operation (see oper-
ational start-up record).
