Introduction 2
ElectroSea®
ElectroSea was created when owners of a sportfishing vessel identified a better way to prevent biofouling in their seawater cooling system. Solving complex technical
problems is their 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 experienced 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 your 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 level of chlorine to protect your 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 pores. ElectroStrainer solves this problem by preventing unwanted
marine growth using electrochlorination generated directly in its sea strainer. Strainer pores remain open, free and clear so protected seawater can pass downstream to
cooling equipment and decreases the frequency of strainer 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 your vessel’s seawater flow 24/7/365 days a year and displays the real-time seawater flow rate.

Safety Considerations
Improper installation can result in unsatisfactory performance, premature failure, damage to systems in the seawater circuit and/or to the vessel.
WARNING Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE Indicates a hazardous situation which can cause damage to personal property, environment, or equipment.
Pre-installation Descaling of Seawater Conduits
Pre-installation descaling ensures any existing biofouling that has accumulated on the interior seawater lines are removed. If seawater lines are impacted with
barnacles and marine growth, then ElectroSea recommends professional descaling prior to installing the ElectroStrainer System. By starting with descaled and
clean seawater lines, you will realize the full benefit of the ElectroStrainer System. For new vessels, descaling is not necessary.
Safety and Pre-Installation 4
NOTICE
Low seawater flow may damage cooling system and other components that depend on this water for proper operation.
It is the owner’s responsibility to monitor the vessel’s seawater flow rate and perform any necessary maintenance.
NOTICE
ElectroStrainer is an all-in-one sea strainer and electrochlorination System. ElectroStrainer replaces existing sea
strainers. If there is an existing sea strainer in the vessel, then remove it and install the ElectroStrainer Canister in the same location.

Optimal Performance and Strainer Flow Alert
5
Strainer Flow Alert: The Strainer Flow Alert feature monitors seawater flow through ElectroStrainer. This smart strainer system notifies the user that 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 a minimum value for a period of time, then “Check Strainer / Flow Alert” will flash on the display (no
audible alert). Flow rate can be set in GPM or LPM, and time duration 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.
Flow Alert feature is default OFF from ElectroSea and must be set 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 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.
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.

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 (most common cause of 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 freshwater when cruising inland, and from extended storms and freshwater run-off.
• Low salinity is the most frequent cause of the CELL Indicator.
• ElectroStrainer will not display “CLEANING” or generate chlorine while vessel is operating in freshwater.
RESOLUTION: Vessel returns 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, then the ElectroStrainer Cell may require a brief rinse with freshwater.
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.

Installation Overview 8
Seawater Connection Overview
1. Locate the vessel’s seawater intake pump, strainer (if existing), and seacock
shut-off valve. Turn OFF ALL seacock shut-off valves in the seawater circuit at
or below the water line. This includes any output seacocks to prevent back
siphoning.
2. The Canister Assembly should be installed before the pump, and before
any seawater cooled equipment such as air conditioners, chillers, etc.
If there is an existing sea strainer, then remove it and install
ElectroStrainer Canister in the same location. Canister Assembly should be
installed at or below the water line, and as close to the thru hull as possible.
3. A chlorinated return line may be connected after the flow sensor and
seawater pump to return chlorinated seawater directly to the ElectroStrainer
Canister Assembly. This will help to prevent growth at the inlet of the strainer
basket. See page 13 for details.

1. The Canister Assembly has directional IN and OUT labels. Seawater MUST enter at the IN port
and flow through and exit at the OUT port.
Failure to route seawater in the direction of the IN and OUT labels
will result in improper operation of the ElectroStrainer System.
2. The ClearVis Flow Sensor has a flow direction arrow and seawater must enter and exit
according to the marked arrow. ClearVis Flow Sensor MUST BE installed on the same
seawater line/pipe as the ElectroStrainer Canister. The Flow Sensor tells ElectroStrainer
how much chlorine to generate. DO NOT install the Flow Sensor on a separate or ancillary
seawater line/pipe from ElectroStrainer.
The Flow Sensor is made of glass filled nylon for superior strength.
However, this makes the threads less malleable and rougher than other plastics. When
sealing to the Flow Sensor, it is recommended that thread sealant, without PTFE, is used.
The ClearVis Flow Sensor measures the velocity of seawater using
speed of sound technology. It is preferable to have 12” (30.5cm) of straight hose before and
after the ClearVis Flow Sensor. This decreases seawater turbulence and improves the speed,
accuracy and precision of the ClearVis Flow Sensor measurement.
DO NOT place a 90° elbow or other flow restrict plumbing fittings
immediately after the ClearVis Flow Sensor output. The Flow Sensor will
be unable to obtain a consistent reading and Control Unit may be unable to enter the
CLEANING mode. The flow sensor can be placed either upstream (suction side) or
downstream (pressure side) of the seawater pump that ElectroStrainer resides on.

There are two options for the location of the ClearVis Flow Sensor:
4. The “BEST” location for the ClearVis Flow Sensor is after the Canister output
with at least 12” of straight hose before and after the Flow Sensor.
The ClearVis Flow Sensor can also be installed on the pressure side
of the pump.
5. An “ACCEPTABLE” location for the ClearVis Flow Sensor is on the output of
the ElectroStrainer Canister with at least 12” of straight hose after
the Flow Sensor.
All seawater flowing through the ElectroStrainer
Canister Assembly must flow through the Flow Sensor. DO NOT split
or divert seawater before the ClearVis Flow Sensor as this will tell the
Control Unit to generate an incorrect amount of chlorine.
6. Connect threaded male or female PVC hose connectors to ElectroStrainer
Canister, and/or flow sensor as shown in picture 4 or 5.
7. Use thread sealant without PTFE on all connections.
PTFE should not be used on plastic parts. Avoid over
tightening plastic parts they may crack and result in sinking the vessel.
8. Use two hose clamps, reversing the clamps, over flexible hose connections.
9. Add flexible hose hanger, hose strap or hose support bracket within 12” of
ClearVis Flow Sensor. Make sure the ClearVis Flow Sensor is supported.

ElectroStrainer can be installed without a
chlorinated return line. The chlorinated return line provides
the greatest protection from biofouling in the strainer basket.
IF THE CHLORINATED RETURN LINE WILL NOT BE USED, THEN USE
ONLY THE SPECIAL 2205 ALLOY PLUG PROVIDED. DO NOT USE
ANOTHER TYPE OF METAL PLUG. This will void the Warranty.
Note: there may be a small amount of biogrowth in the strainer
basket if the chlorinated return line is not used.
The chlorinated return line decreases the
overall flow rate to downstream equipment. Check downstream
equipment flow requirements and DO NOT add a chlorinated
return line if this will result in low flow to cooling equipment.
1. To prevent growth at the inlet of the ElectroStrainer basket, a chlorinated return line should be
connected from the pressure side of the pump to the Canister Assembly’s 90-degree fitting
located under the inlet port.
2. Connect this chlorinated return line with a tee-fitting and ball valve to the pressure side of the
pump. Note: The source for the chlorinated return line must be after the seawater pump
(on the pressure side) and after the ClearVis Flow Sensor.
3. Connect the chlorinated return line tubing suppled with the Canister Assembly to the 90-degree
hose barb fitting directly under the inlet port. Secure the tubing with two hose clamps, reversing
directions, and clamp securely.
4. Secure the chlorinated return line tubing with Strain Relief Clamp. The Strain Relief Clamp can be
connected to the feet or wall bracket. Use included mounting screw or nut and bolt.
