PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Low product flow rate
Low pressure feeding
membrane
Verify that the incoming tap
water supply is fully open.
The pressure on the prefilter
gauges should be > 20 PSI
when the MROZ is operating.
Low pump PSI.
Pump should be operating
at:
MRO3Z 100-140 PSI
MRO4Z 100-160 PSI
MRO5Z 100-160 PSI
MRO6Z 100-160 PSI
MRO7Z 100-180 PSI
MRO8Z 100-200 PSI
Reject GPM flow rate too
high.
Adjust Reject Water flow
rate.
Excessive PRODUCT line
backpressure.
Check for restrictions in the
PRODUCT WATER FOR
DIALYSIS hose. Check the
feed pressure gauge on the
dialysis machine. If the
dialysis machine does not
have a pressure gauge,
install one inline.
Low temperature incoming
tap water.
RO+ membrane performance
is affected by water
temperature. The Product
Water Flow Rate and Output
decreases as the
temperature of the Incoming
Tap Water decreases.
Prefilter clogged.
Check the prefilter gauges
for pressure drop. Replace
the prefilter cartridge if the
pressure drop is > 10 PSI.
Membrane needs replaced.
Replace the membrane.
High Bacteria Count
Too long since the last
disinfection or the procedure
was not performed correctly
Disinfect the MROZ following
the procedures in Section 5.
