8. With your mouth, blow into port “P”, air should expel from port “A” which is the “normally closed” or “good water”
port.
9. If it is extremely difficult to expel air from port “A” or if no air expels from port “A”, then port “A” requires adjustment.
10. Again blow into port “P” while plugging port “A” with a fingertip. No air should expel from port “B”.
11. If air expels from port “B”, then port “B” requires adjustment.
Solenoid Valve Coil Check
The 3-way Product Diversion Valve Solenoid operates from 12 VDC. To check the condition of the Diversion
Valve solenoid coil:
a) While System is operating and while the Water Quality less than 1000ppm, remove the din connector from
the valve’s coil. Using a voltmeter set to DC, check the voltage at the din connector terminals.
b) If 12 VDC is present at the din connector terminals then the control circuit is operating normally, but the
3-way Diversion Valve Coil may be defective. Check the solenoid coil continuity.
c) Using an Ohm meter measure the continuity of the solenoid coil as shown below.
Measure the DC resistance between pins 1 & 2. Proper resistance reading is approx. 12 to 15 W .

d) If an open circuit exists, or if the resistance is much greater than or less than 12 to 15 , then replace the
solenoid coil or the entire valve.
e) If 12 VDC is not present at the din connector terminals, then the cable connections may be loose, the cable
may be broken, or the control circuit may be defective. Check these components.
f) Check for 12 VDC at the connection points of the Diversion Valve Solenoid Coil on the Control Printed Circuit
Board terminals.
g) If 12 VDC is present while system is operating and the Water Quality less than 1000ppm, then the Diversion
Valve cable is loose at one of the connections or the cable is defective.
h) If there is no voltage present while system is operating and while the “safe water” lamp on the Touch Pad
is illuminated green, then troubleshoot the Control Printed Circuit Board.
Flow Meter [20]
Since the flow meter body is clear, light penetrates it and supports biological growth. To clean the flow meter body,
remove the top access fitting, the guide rod, float and O-Ring bumpers, and tube stops. Clean the interior of the
tube using a bottlebrush, soft rag, cotton swab or other soft item. Reassemble the unit.
