Salinity Meter registers potable water, but the product water has a definite salt taste.
There is a blockage in the Brine Discharge Line causing Brine Discharge Water intrusion into the 3-way
Product Water Diversion Valve. The 3-way Product Water Diversion Valve Seats have been tampered
with and require proper adjustment.
The Salinity Probe may be dirty and require cleaning
Salinity Level Calibration
Note: In order to set the Diversion Valve trip point precisely, the following procedures must be
followed using a known test solution of 1,000 ppm TDS.
1. Disconnect the system from power source.
2.
To facilitate the calibration and test, temporarily disable the Booster Pump and High
Pressure Pump by removing power cords at TB-1 in the Main Power Enclosure, after noting
the original connections.
3.
Remove the Salinity Probe from its mounting tee, and wipe electrodes clean with a clean
soft cloth or paper towel.
4.
Disassemble the Controller Enclosure and open the enclosure by 4 screws.
5.
Restore the power to the system and press the “Start” switch. Wait for approximately 10
seconds.
6.
If the Salinity Probe is exposed in the air and it is dry, the “Water Quality” LED turns green.
7.
If the LED does not turn on green, disconnect probe cable from the circuit board terminals
(refer to the Main Board figure on page I - 12). If the LED comes on green, inspect the
Salinity Probe thoroughly and replace it if necessary.
8.
Dip the Salinity Probe electrodes well into the test solution of 1,000 ppm.
9.
Turn the “SALINITY SET” control to fully clockwise position, then slowly turn back
counter clockwise until the LED turn red. Do not over turn. Note that there is a 5 second
delay for the LED to change from red to green, no delays from green to red.
10.
This completes the calibration of the Salinity Level.
11.
Disconnect the system from power source and revert disconnected wires to original
terminals, and assemble enclosures.
