13. Rotate the handle on the product water 3-way sample valve so it is pointing towards
the storage tank connection (rear of unit).
Performance Monitoring (optional)
Once the system has been flushed initially, the outlet and drain water flow rates and water
quality can be measured. These measurements can be taken at any time and compared with
the initial values to detect any changes in system performance. Product water volume and/or
quality are affected by a number of factors including inlet water pH, dissolved solids, pressure
and temperature. Changes in these parameters will affect system performance.
Published performance specifications are based on certain standardized conditions. Variations
from these conditions can be expected to affect actual measured performance. These
conditions assume new filter/RO cartridges, differential pressure across the RO module equal to
specification pressure and inlet water temperature at the specification value. Increases
(decreases) in pressure and/or temperature will result in increased (decreased) production
rates.
Close the tank inlet valve and open the product water
sample valve to obtain a sample. The flow
rates can be measured with a stopwatch and a graduated cylinder or calibrated measuring cup.
The drain water flow rate can be measured from the end of the red tubing in a similar manner.
Inlet water flow = Outlet (Product) Water Flow + Drain Water Flow
Water quality can be determined by measuring the total dissolved solids (TDS) of the outlet
water sample. A laboratory or hand held TDS/conductivity tester should be used for this
measurement. Optionally, TDS measurements are used to calculate Total Dissolved Solids
percent reduction as an indication of system performance. Percent reduction can be used to
determine when the RO cartridge should be replaced.
TDS Measurement
1. Rinse a clean cup or graduated cylinder twice with the outlet water. Then collect enough
fresh sample to measure with your conductivity tester.
2. Following the instructions of your conductivity tester, measure and record the
TDS/conductivity value of the outlet water sample.
TDS Reduction Calculation (optional):
1. Obtain an outlet water sample and TDS measurement as described above.
2. Obtain an inlet water sample in the same manner as above, but from the inlet water
source to the MRS-200 system.
3. Using your TDS/conductivity tester, measure and record the TDS/conductivity value of
the inlet water sample.
4. To determine percent reduction, apply the two TDS/conductivity values obtained to the
following equation:
Inlet TDS – Outlet TDS
Inlet TDS
x 100 = % TDS Reduction
