Introduction
ElEctroSEa®
ElectroSea was created when the owners of a sportfishing vessel invented “a better way” to prevent biofouling in their seawater cooling system. Solving complex
technical problems is our expertise. With more than 100 issued U.S. patents and 350+ foreign patents in advanced technologies, our executive management team
has been developing innovative solutions for more than 50 years. With an expert team of “old salts” who eat, sleep, and breathe boating, ElectroSea will improve
your time on the water.
ElEctroStrainEr®System
ElectroStrainer is a revolutionary seawater biofouling prevention device, a sea strainer, and a smart seawater flow-monitoring unit all combined into a single
system. ElectroStrainer provides an entirely new way for boaters to prevent biofouling, barnacles, and bioslimes from clogging sea strainers and seawater pipes
for air conditioners, chillers, and refrigerators. ElectroStrainer provides ease of use never seen before in a sea strainer and completely redefines seawater system
maintenance.
• ElectroStrainer is a Biofouling-Prevention Device: ElectroStrainer continuously creates a safe and effective low level of chlorine to protect the entire
seawater system. ElectroStrainer contains a Cell with a proprietary mixed metal-oxide coating. When electrified, it acts as a catalyst to generate chlorine
naturally from the seawater passing through it. No chemical additives are required.
• ElectroStrainer is a Sea Strainer: Typical sea strainers become clogged as bioslime, algae, and barnacles build up over time in the strainer basket pores.
ElectroStrainer solves this problem by preventing unwanted marine growth by generating chlorine directly inside its sea strainer basket. Strainer pores remain
open, free, and clear so protected seawater can pass downstream to cooling equipment and decrease the frequency of strainer-basket cleaning.
• ElectroStrainer is a Smart Seawater Flow-Monitoring System: ElectroStrainer provides real-time monitoring with Smart Strainer Alert technology and
automatically notifies you to check the strainer if it requires attention. ElectroStrainer monitors vessel seawater flow 24/7/365 days a year and displays the
seawater flow rate in real time.

Operating Modes
The Operating Mode displays the state of the ElectroStrainer System. Modes include
• OFF: ElectroStrainer is powered, but it is in the OFF mode and not Cleaning.
• START-UP: ElectroStrainer is performing a diagnostic self-test. This mode lasts for approximately 30 seconds.
• CLEANING: ElectroStrainer is ON and Cleaning. This is the normal operating mode for the ElectroStrainer System.
• STRAINER FLOW ALERT: ElectroStrainer is ON and Cleaning, but the flow rate measured is less than or equal to the value set manually in the Flow Alert feature.
• CELL INDICATOR: ElectroStrainer is sensing low salinity (brackish or fresh water), high resistance, or disconnection of the Cell Cable. This indicator may also
mean the Cell is at the end of its useful life.
Feature Overview
• Flow Rate (GPM): The flow rate is monitored in gallons per minute (GPM) or liters per minute (LPM) at the output of the ElectroStrainer System.
• Strainer Flow Alert: The Strainer Flow Alert indicates the strainer basket has debris and/or the flow rate is at or below a threshold level for a period of time.
• Display Contrast, Backlight, and Imperial/Metric Units: Use this feature to adjust the LCD display contrast and backlight levels from Lo to Hi and to select
between imperial and metric units for flow in GPM or LPM.

System Features
Optimal Performance
Constant Chlorinated Seawater Flow: The ElectroStrainer System should be powered ON and have seawater flowing through it whenever possible.
This provides the vessel’s seawater circuit with constant chlorinated seawater to prevent unwanted marine growth. Intermittent or stagnant seawater
that is not continuously electrochemically treated allows growth of marine microorganisms. Barnacles have the innate ability to close themselves off and survive
intermittent exposure to biocidal agents:
• DO NOT turn off seawater pumps, air conditioners, or chillers for an extended period of time.
Inspect the vessel for problem areas:
• Pre-existing biofouling in seawater lines prior to ElectroStrainer installation
• Clogged seawater intakes
• Impacted, blocked, or occluded lines from debris lodged in plumbing
• Sporadic demand valve areas (Depending on the system, valves that turn on and off can foster unwanted marine growth.)
Strainer Flow Alert: The Strainer Flow Alert feature monitors seawater flow through the ElectroStrainer. This smart strainer system notifies the user if the
ElectroStrainer basket contains debris, such as seaweed or mud; or part of the seawater circuit, such as the intake screen or thru-hull fitting, is partially blocked; or
the seawater pump is producing low flow and requires maintenance. The Strainer Flow Alert feature allows the user to set a minimum seawater flow rate threshold
value and time duration. If the seawater flow rate drops below the minimum value for a period of time, “CHECK STRAINER / FLOW ALERT” will flash on the display (no
audible alert). Flow rate can be set in GPM or LPM, with the time duration set in minutes. To set the Strainer Flow Alert value, go to Menu, Flow Alert and enter the
desired threshold flow rate and time duration for notification.
The Strainer Flow Alert feature is OFF by default and must be set up by the installer or end user.
ElectroStrainer will continue generating chlorine even after a Strainer Flow Alert occurs.
If a Strainer Flow Alert occurs
1. Check vessel’s intake screens for blockage or debris.
2. Check seawater pump output, impeller, or other causes of low flow.
3. Check ElectroStrainer basket for debris, seaweed, or mud.

Cell Indicator: The Control Unit will display “SALINITY/CELL,” “% OUTPUT,” and illuminate the red Cell LED in various conditions. This is not an immediate cause for
concern and may be temporary depending on seawater salinity level. ElectroStrainer will continuously attempt to generate chlorine and automatically resume
standard operation when conditions are resolved. The Cell Indicator will be illuminated if any of the following conditions occur for multiple consecutive days:
• Water salinity is below 20 parts per thousand. (This is the most common cause of a Cell Indicator notice.)
• ElectroStrainer Cell Cable or its connectors have been compromised.
• ElectroStrainer Cell has excessive mud or other debris.
• ElectroStrainer Cell is at the end of its useful life.
Water Salinity
• Vessels often encounter brackish or fresh water when cruising inland or from extended storms and freshwater runoff.
• Low salinity is the most frequent cause of the Cell Indicator.
• ElectroStrainer will not display “CLEANING” or generate chlorine while the vessel is operating in fresh water.
RESOLUTION: Return vessel to seawater with adequate salinity.
ElectroStrainer Cell Cable
• The ElectroStrainer Cell Cable and connections must not be spliced, cut, compromised, or damaged.
• Inspect the Control Unit-to-Cell Cable carefully. Look for any corrosion at the connectors.
RESOLUTION: Replace the ElectroStrainer Cell Cable if it is compromised.
Excessive Mud or Other Debris
• If there is excessive mud or other debris, the ElectroStrainer Cell may require a brief rinse with fresh water.
RESOLUTION: Follow instructions on pages 10-15.
ElectroStrainer Cell at End of Life
• When the ElectroStrainer Cell has reached the end of its useful life, it can no longer generate chlorine. The Cell life is dependent on flow rate, hours of use,
seawater quality, and other factors.
RESOLUTION: Contact your ElectroSea dealer.

Inspection
The ElectroStrainer should be viewed during regular inspection of the vessel’s engine room. During normal operation, the ElectroStrainer status screen will flash
the message “CLEANING,” and the green LED will be illuminated. This indicates the ElectroStrainer System is generating a safe and effective low level of chlorine to
prevent unwanted marine growth, barnacles, and biofilm in the strainer and seawater lines.
If there are any concerns during the regular inspection noted above, perform a more thorough process:
• Visually inspect all wires and connections between the Control Unit and the Canister Assembly.
• Disassemble the Canister Assembly and thoroughly flush the strainer basket and Cell with fresh water.
• Visually inspect the ClearVis Flow Sensor.
• Visually inspect seawater conduits downstream of ElectroStrainer to confirm marine-growth prevention.
Inspection and maintenance are the responsibility of the vessel owner.
