Inlet Thru-Hull Fitting with Forward Facing Scoop
The inlet thru-hull fitting must be dedicated to only the Sea Recovery Reverse Osmosis System. It is important that
the installer utilizes a forward facing scoop so that the system receives a positive flow of water while the boat is
underway. The fitting must be installed on the boat's hull in a position that provides continual feed water flow without
air to the system.
Caution: A flat or flush inlet thru-hull fitting will cause a vacuum as the boat is under way and this will cause
loss of feed water flow and cavitation of the Feed pump resulting in continual System shut down due to low
feed water flow and pressure. The resulting failure of the System to remain in operation is attributed to
improper installation, is the liability of the installer, and is not covered by the Sea Recovery Reverse Osmosis
warranty.
Caution: If the thru-hull fitting is placed in a position that allows air to continually enter the thru-hull fitting
this will cause the system to continually shut down due to loss of feed water. The resulting failure of the
System to remain in operation is attributed to improper installation, is the liability of the installer, and is not
covered by the Sea Recovery warranty.
Caution: The Sea Recovery Reverse Osmosis System must not be tied into another existing auxiliary water
line already supplying another accessory on the boat. Connecting the Sea Recovery RO System into a thru-
hull fitting already supplying other equipment will cause the Sea Recovery RO System to draw air or cavitate
leading to continual system shut-down or may starve the other equipment.
Caution: The Sea Recovery Reverse Osmosis System must not be tied into another existing reject
overboard auxiliary water line, already supporting another accessory on the boat. Connecting the Sea
Recovery RO System into a thru-hull fitting already supporting other equipment will cause the Sea Recovery
RO System build excessive pressure or bursting reject water line. Damage to and failure of the system due to a
connecting into auxiliary reject overboard line will not be covered by the Sea Recovery Warranty.
Caution: If the Sea Recovery RO System is connected to a Sea Chest or Stand Up Pipe, DO NOT plumb
the Sea Recovery RO System feed line to the "top" of the Sea Chest or Stand Up Pipe. If plumbed into the
top of these feed water arrangements, the Sea Recovery RO System will experience continual shut-down
due to air inducement into the system. Plumb the Sea Recovery RO System to the "bottom" of such feed
water arrangements to ensure a continual air-free supply of feed water to the system.
The resulting failure of the system to remain in operation due to any of the above improper installation is
the liability of the installer and is not covered by the Sea Recovery Reverse Osmosis Warranty.
 Inlet Sea Cock Valve quarter-turn ball valve min. 1/2" size, with a 1/2" MNPT connection for mating to the supplied
1/2" FNPT fitting.
 Brine Discharge Thru-Hull Fitting minimum 1/2" size with a 1/2" MNPT connection for mating to the supplied 1/2"
FNPT fitting. The Brine Discharge Thru-Hull Fitting should be installed above water level. No valves should be
installed in this line. Damage to and failure of the system due to a closed valve will not be covered by the Sea
Recovery Warranty.
 Connection of the Potable Water Storage Tank Tube Connector to the boat's Potable Water Storage Tank requires
a 1/4" FNPT connection for mating to the supplied 1/4" MNPT fitting. In order to avoid problems such as reverse
flow (osmosis) from the tank to the system and chlorination attack of the RO Membrane Element, the fitting must
terminate above the maximum water level. Tying into the tank fill line is a good choice. No valves should be
installed in this line. Damage to and failure of the system due to a closed valve will not be covered by the Sea
Recovery Reverse Osmosis Warranty.
 Connection of the Sea Recovery Freshwater Flush subassembly to the boat's pressurized potable water line
requires a 3/8" FNPT connection for mating to the 3/8" MNPT fitting supplied with the Freshwater Flush subassembly.
 Circuit Breaker with appropriate amperage rating.
 Properly-Sized Power Cables.
 An electrical power source capable of delivering the required constant voltage and cycles during start-up and
operation of the system.
