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 barnacles, biofilm, and marine growth that have 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 CLEARLINE System.
By starting with descaled and clean seawater lines, you will realize the full benefit of the CLEARLINE System. For new vessels, descaling is not necessary.
uWithout CLEARLINE
 ■ Hours–Complex multispecies microbial biofilm forms
 ■ Days–Secondary colonizers arrive and multiply
 ■ Weeks–Macroscopic communities of algae and invertebrates grow
uWith CLEARLINE
The advanced CLEARLINE electrochlorination system continuously
prevents barnacles and biofilm build-up
Safety and Pre-Installation 4
NOTICE DO NOT perform acid descaling after the CLEARLINE System has been installed. Descaling acids will damage the ClearCell
canister, ClearCell Electrode and void the Warranty.

Optimal Performance and Flow Alert
5
Flow Alert: The Flow Alert feature monitors seawater flow through the ClearCell. This feature allows the user to set a minimum flow rate threshold value and time
duration. If the seawater flow rate drops below a minimum value for a period of time, then “Flow Alert” will appear on the display (no audible alert).
This feature notifies the user that some part of the seawater circuit such as the intake, strainer, pump, or internal screen on the ClearCell requires cleaning or is
not functioning properly. Flow rate can be set in GPM or LPM, and time duration in minutes. To set the Flow Alert value go to MENU, Flow Alert, and enter desired
threshold flow rate and time duration for notification.
Flow Alert feature is default OFF from ElectroSea and must be set-up by the installer or end user.
CLEARLINE will continue generating chlorine even after a Flow Alert occurs. Flow Alert does not prevent CLEARLINE from operating.
If a Flow Alert occurs:
1. Check vessel’s strainers and intake grates for blockage
2. Check seawater pump operation
3. Check ClearCell Internal Screen (see Operation Manual, Pg. 10)
Optimal Performance
Constant Chlorinated Seawater Flow: The CLEARLINE System should be powered ON and have seawater flowing through the ClearCell at all times.
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 conditioner, or chiller for an extended period of time.
Inspect the vessel for problem areas:
• Pre-existing biofouling in seawater lines prior to CLEARLINE installation.
• Clogged seawater strainers and 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.

Internal Screen and Cell Indicator
The ClearCell contains an internal screen to catch debris before it reaches the Flow Sensor (debris, tiny
shells, or other foreign materials that pass through the vessel’s main strainer). The internal screen
should be cleaned periodically, and whenever debris gets caught in the screen and decreases seawater
flow. See CLEARLINE Operation Manual, Pg. 10-15 for detailed instructions to clean internal screen.

NOTICE
• DO NOT PERFORM ACID DESCALING OF SEAWATER CIRCUIT AFTER THE CLEARLINE SYSTEM
HAS BEEN INSTALLED.
• DESCALING ACIDS OR CLEANING CHEMICALS WILL DAMAGE THE CLEARCELL CANISTER,
CLEARCELL ELECTRODE AND VOID THE WARRANTY.
• DO NOT TOUCH THE CLEARCELL ELECTRODE PLATES OR USE ANY TYPE OF MECHANICAL BRUSH.
• THE CLEARCELL ELECTRODE PLATES CONTAIN A SPECIAL METAL OXIDE COATING THAT WILL BE
PERMANENTLY DAMAGED IF YOU HANDLE IT.
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 and perform any maintenance on the vessel’s seawater pumps, strainers, and screen in ClearCell.
NOTICE
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. CLEARLINE will continuously attempt to generate chlorine and automatically resume standard
operation when conditions are resolved. The CELL indicator will be illuminated during installation if any of the following conditions occur:
• Water salinity is below 20 parts per thousand (most common cause of CLEARLINE CELL indicator notice)
• ClearCell cable or its connectors has been compromised
See CLEARLINE Operation Manual, Pg. 9 for CELL Indicator Troubleshooting.
