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 water and the valve’s
solenoid coil is not defective, the valve’s solenoid coil is warm or hot to the touch, 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 internal ports may have been moved by over tightening of the black tube fittings causing
blockage internally and require adjustment. Remove Diversion Valve from the system and adjust ports.
High Pressure Pump Abnormalities
High Pressure Pump flow is normal when the system operating pressure is below 100 PSI, but the flow drops or becomes
erratic and pulsates as pressure is applied.
• Warn High Pressure Seals from normal use require replacement.
• Worn High Pressure Pump valves, valve seats, valve springs and/or valve seat "O" rings are broken or warn due
to normal use and are allowing internal by-passing. Repair the pump with a Valve and Seal Kit.
Pump is noisier than usual and pulsations are observed in hoses and gauges.
• Worn or broken Valve, Valve Spring, or Valve Seat. Repair the pump with a Valve and Seal Kit.
• Pump is cavitating and not receiving sufficient feed water at its inlet due to blockage prior to the pump’s inlet port.
Clear the blockage in the feed water line.
High Pressure Pump Leaks Oil
Determine source of leak and replace appropriate associated seal.
High Pressure Pump leaks water between manifold and Drive End.
• Worn Inlet Packings due to normal use
• Worn Inlet Packings due to operation under a vacuum condition
• Worn Inlet Packings because pump has been operated dry, without inlet feed water.
• Repair the pump with a Seal Kit.
If the High Pressure Pump electric motor fails to operate, follow these steps to isolate the problem.
1. Ensure that the system is receiving proper power from the power source.
2. Press “Start” switch to activate the motor. It will take approximately 10 seconds before the High Pressure Pump
Motor starts. Do not press any other switch.
3. Measure the AC voltage between terminals 4 and 5 (AC Systems) or 3 and 4 (DC systems) on the main terminal
strip.
4. If the voltage measured in the step 3 above matches the system voltage, then problems may be in the power
cable attached to the motor or the motor internal wiring or windings.
5. If low or no voltage is present in step 3 above, then check for proper operation of the High Pressure Pump
Contactor. To deactivate the contactor, press the “Stop” switch twice. To activate the contactor again, press
the “Start” switch.
6. If the contactor is mechanically operating, but no voltage is present at the motor terminal (step 3 above), then
the High Pressure Pump Motor contactor may be at fault.
