• No kinks, blockages or air suction leaks in the inlet line
• The Feed Pump is operational and delivering flow and pressure
• Whether or not the Inlet Thru-Hull Fitting is clean (no manufacturing or installation debris) and if air suction leaks
are present
• Caulking compound within the opening
• Shipping cover or tape below the hull in the water
• Casting slag on the “fingers” below the hull in the water or within the orifice
• Plastic bag or other debris in the water below the hull in the water
Error ID 4: Low Voltage Fault
Check system voltage inside the Control Panel. The system must receive adequate voltage at start up and during
operation for normal operation. DC systems will shut down by design when the voltage falls below:
• 12 VDC Systems: 10.5 VDC
• 24 VDC Systems: 21.5 VDC
3-Way Product Water Diversion Valve Abnormalities
1. The Water Quality is less than 1000ppm; however, the Diversion Valve does not divert potable water to the post filtration
section and onto the boat’s potable water storage tank.
1. 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.
2. The 3-way Diversion Valve is receiving 12 VDC when the Water Quality is less than 1000 ppm safe water. The valve’s
solenoid coil is not defective, nor is it warm or hot to the touch; however the Diversion Valve does not divert potable
water to the post filtration section and onto 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 or Low-Pressure Abnormalities Due to Mismatch of Components
The Seafari Quest System is designed to recover a fixed percentage of the feed water as product water. The
System self-adjusts the operating pressure in order to maintain a constant and set product water flow. Therefore,
the System will never experience greater than or less than normal product water flow, unless there is a failure or
abnormality.
Three components must be properly matched in order to attain acceptable operating pressure limits and resulting
product water production limits: the ETD, RO Membrane Element and the Feed Pump. Upon leaving Horizon
Reverse Osmosis’ factory at the time of shipment, these components have been matched and tested together as
a system.
If the initial Horizon Reverse Osmosis customer (distributor, dealer or boat builder) has mistakenly interchanged
one or more of these components with other system components in their stock, this will cause a mismatch resulting
in insufficient operating pressure, insufficient product water flow, excessive operating pressure or excessive product
water flow. If one or more of these components has recently been replaced, it may have been replaced with the
incorrect component.
If the system is new and being operated for the first time or if one or more of the above-mentioned components
has recently been replaced, check to ensure that the three components are properly matched. Refer to the following
two pages.
