Horizon Reverse Osmosis Seafari Quest Compact 200, Owner'S Manual

Page: 25 / 116

Important: The Sea Cock Valve, Inline Pressure Gauge, Sea Strainer, Rinse Clean Inlet Valve, and Booster
Pump should be installed below water level. This will aid the Booster Pump in priming.
Important: Always allow hoses and tubes to enter and exit straight from the connection for a minimum of 1
in. prior to a bend. If stress is placed on the fitting due to a tight bend, the fitting will leak and may break.
Important: All connection lines should be as short and straight as possible using minimum fittings. Ensure
that they are not “kinked.”
Important: Ensure that the power source is sufficiently sized to provide the correct voltage and cycles during
System start up and operation.
Remember: Install the system and its supporting components in an accessible manner.
Special Considerations
Length of Connection Lines
• All connection lines should be as short and straight as possible using minimum fittings.
• Increased length causes vacuum and line-loss in the Suction chapter of the Feed Water line.
• Increased length causes pressure loss in the Pressurized chapter of the Feed Water line.
• Increased length causes excessive pressure build up in the Brine Discharge line.
• Increased length causes excessive pressure build up in the Product Water line.
• The connection lines must not be kinked.
• Kinks in the Feed Water line cause Booster Pump cavitation and continual System shut down.
• Kinks in the Pressurized chapter of the Feed Water line cause excessive pressure build up and damage, as
well as loss of required pressure to the ETD.
• Kinks in the Brine Discharge line cause excessive pressure build up and damage.
• Kinks in the Product Water line cause excessive pressure build up and damage.
Accessibility
• Install the system and supporting components in an accessible manner. The Seafari Quest System requires
regular operator maintenance such as filter element changing. As with any Electro Mechanical system utilized in
the Marine environment, the Seafari Quest System will require repair from time to time. Hidden or out of reach
items may become forgotten, not maintained, and cause damage to other system components.
• The Electrical Control Panel Touch Pad must be accessible for operation of the System.
• The ETD and RO Membrane Element Pressure Vessel must be accessible for Membrane Element cleaning,
rinsing, storing, and winterizing.
• Sea Strainer, Prefilters, Charcoal Filter, and pH Neutralizer must be accessible for user changing.
Components Supplied by the Installer or Owner
Caution: All fittings, valving and piping installed prior to, within, and after the Horizon Reverse Osmosis
System must not contain iron; they must be non-ferrous material (not containing iron). Iron fittings or piping
will cause rust fouling and failure of the RO Membrane Element. The resulting failure of the RO Membrane
Element is attributed to improper installation, is the liability of the installer and is not covered by the Horizon
Reverse Osmosis Warranty.
