•
Charcoal Filter element is fouled, replace element
•
pH Neutralizer element is fouled, replace element.
•
3-way Product Water Diversion Valve is blocked, or inner ports are out of adjustment, adjust
inner ports.
There is a Sulfurous odor (rotten eggs) in the product tank.
1. Dirty Pre-Filtration Element.
•
Dirty Pre-Filtration Elements allow biological matter to decay. When this biological
matter decomposes, sulfur gas is released as a byproduct.
•
Check and replace as necessary Prefiltration and Post Filtration Elements.
2. Charcoal Filter Element requires replacement. Change the Charcoal Filter Element every 3
months.
3. Product Tank is dirty or has biological growth in it. Clean and Chlorinate product tank.
The UV sterilizer is flickering or does not light. (Ultraviolet light will damage skin and eyes. Do not
look directly at the UV lamp!)
1. UV lamp is weak due to length of time in use, in excess of 1,000 hours. Replace the UV lamp.
2. The UV ballast is very sensitive to voltage changes. Ensure that the voltage supplied
to the UV sterilizer is within 11.5 VDC to 13 VDC.
7.3 3-way Product Water Diversion Valve Abnormalities
When the system is producing “unpotable” water and the Water Quality lamp is illuminated
“red” the 3-way Product Water Diversion Valve coil will not receive voltage from the controller.
This allows the 3-way Product Water Diversion Valve to divert the “unpotable” water to the
Brine Discharge.
When the system is producing “potable” water and the Water Quality lamp is illuminated
“green”, the 3-way Product Water Diversion Valve coil will receive 12 VDC from the controller.
This allows the 3-way Product Water Diversion Valve to divert the “potable” water to the post
filtration section and on to the boat’s potable water storage tank.
The Water Quality is less than 1000ppm, however, the Diversion Valve does not divert potable
water to the post filtration section and on to the
boat’s potable water storage tank.
The Diversion Valve is not energizing, and the
valve’s coil is cool to the touch after several
minutes of operation with the Water Quality is less than 1000ppm.
•
The 3-way Product Water Diversion Valve may have a defective solenoid coil.
•
There may be a loose wire connection at the Control Printed Circuit Board or the solenoid’s din
connector.
•
The Control Printed Circuit Board may not be delivering 12 VDC to the solenoid.
The 3-way Diversion Valve is receiving 12 VDC when the Water Quality less than 1000ppm safe
