After startup
flushing, the
system begins
to produce RO
pure water. You
can monitor it
through the RO
premeate flow
meter.
Typically KSRO
permeate flow
rate is 2.8 GPM /
10.5 LPM.
After startup
flushing, the
system begins to
produce RO pure
water. You can
monitor it
through the RO
premeate flow
meter.
Typically KSRO
permeate flow
rate is 4.4 GPM /
16.7 LPM.
* Permeate Flow Rate is calculated based on Rotek XL-4040 membranes
It is also possible to use other brands of membranes with KSRO units, but the flow rate may vary.

Troubleshooting
Why does my KSRO keep on and off??
The pressure at the raw water inlet end is insufficient, or the inlet pipe is too small. If the water supply
pressure is lower than 35kPa, please use an external booster pump, please use the water supply storage tank
and booster pump to supply water to the RO system and prevent the system from circulating.
Why is the output of my RO pure water getting less?
1.
If the output of RO pure water becomes smaller, which is about 20% lower than your usual flow rate,
and the pressure of the RO water inlet pressure gauge becomes larger, it means that the RO membrane is
clogged and needs to be replaced or cleaned.
2.
If the RO system is in the state of producing water, and your KSRO pure water flow rate drops a lot
(like 50%), It means that the pre-filter element is clogged and needs to be replaced.
Important Reminder Please record the values of your RO permeate flow meter and pressure gauges, and test
the water quality at the same time. Those data will be of great help to quickly eliminate obstacles. Please refer
to the Operation Log attached at the end of this document.
