4. The control system for the RO3X ships with resistor R10 (see above) that can be identified
by its color bands (Red-Violet-Red-Gold). If your feed water conductivity exceeds 1,000
µ
S/cm, you may want to change out the resistor in the R10 position with a replacement
resistor, provided by AmeriWater. This replacement resistor can be identified by its color
bands (Blue-Grey-Red-Gold). Alternatively, if you have an ohm-meter, the original resistor
can be identified by its resistance value of 2.7 kΩ; the replacement resistor’s resistance
value is 6.8 kΩ.
5. Remove the R10 resistor with needle nose pliers.
6. Move the replacement resistor to the R10 position.
7. Save the R10 resistor somewhere safe.
8. Close RO controller door.
9. Re-apply power to RO.
10. Go into setpoints in the controller (Ref. Section 10.1).
11. Change the C2 Range setpoint to meet your needs. C2 Range setpoint 5 is 0-2500, 6 is 0-
5000.
12. Once the setpoint has been changed, then you need to calibrate the units by taking a
sample of the permeate water and testing it with a calibrated conductivity meter.
