CLEARWATER LM INSTALLATION Clearwater LM Installation Clearwater saltwater chlorinators must be installed by a qualified swimming pool professional or certified electrician. If you need assistance in finding a qualified installer please contact our technical service department at 1-888-537-6657. Installing the cell The Clearwater cell MUST be installed horizontally, with the ports down, as the last piece of pool equipment in line. (The design of the cell forms a natural gas trap.
Flooded Plumbing Installation This occurs when the water level of the pool is above the height of the pool equipment. Some pool systems may have valves that will isolate the equipment. If not, one ball valve should be installed on the inlet side of the cell and a one-way check valve should be installed on the outlet side of the cell.This will eliminate the possibility of having a gas build-up and possible cell damage.
Salt Always test the salt level before adding salt. Refer to page 18 & 19 for instructions on adding salt. Safety Test After installing the Clearwater chlorinator the following safety test MUST be performed. Turn on the pool pump and the chlorinator. Adjust the chlorine output to maximum. Disconnect the blue sensor clip from the terminal pin at the end of the cell. The RED "no flow" light should be illuminated and the output lights should drop to the minimum, showing a yellow light only.
HOW YOUR CLEARWATER CHLORINATOR WORKS How your Clearwater Chlorinator Works Common salt (sodium chloride) is made up of two elements, sodium and chloride.When your Clearwater LM2 is installed, a measured quantity of salt is dissolved in the pool water to make it slightly salty.As part of the daily filtration cycle, the pool water is passed through the Clearwater electrolysis cell to produce chlorine which is dissolved instantly into the water.
CLEARWATER MODEL LM2 OPERATION Clearwater Model LM2 Operation The chlorine production of the Clearwater LM2 is controlled by the number of hours the LM2 and filtration system is ON, as well as the setting of the output control. Power to this unit must be controlled by the pump timer.The chlorinator functions may only be set when the filtration system is running.
CONTROL PANEL FUNCTIONS Control Panel Functions On / Off Button. This button switches the LM2 ON and OFF. A yellow light appears in the chlorine output indicator window when the unit is ON. Output Button. The output button is used to set the chlorine output of the LM2. Chlorine output is selected by repeatedly pushing this button until maximum is reached on the chlorine output indicator. An extra push of this button will reset the output to minimum. Super Chlorinate Button.
CONTROL PANEL FUNCTIONS LM2 Display Panel 13
INDICATOR LIGHTS – WHAT THEY MEAN Indicator lights: What they mean Chlorine Output. A series of six lights indicate the chlorine output setting of the power pack. More lights equals greater chlorine production. Note: This setting does not show the actual chlorine reading in the pool. Use of a test kit is required to confirm the Salt Level or Free Chlorine reading of the pool water. Chlorine Output - Yellow Light Flashing.
OPERATING TIPS Operating Tips A. Filtration and chlorination system operating periods. Run your filtration and chlorination system for at least 6 to 8 hours per day. During very hot weather it might be necessary to run the system for additional hours, but in winter where pools remain open, it is only necessary to run the filtration system for around 4 hours per day. Shorter periods will help to lengthen the life of the cell electrodes. B. Chlorine output settings.
OPERATING TIPS F. Regular maintenance checks. Weekly: • • • • • Visually check the cell electrodes. Only if necessary, remove the cell and flush with a garden hose to remove any debris that may have passed through the filter and lodged in the cell housing.Avoid inserting objects into the cell which can scratch or bend the cell plates. Check the free chlorine. Check the total alkalinity.Adjust if necessary. Check the pH of the water.Adjust if necessary.
SALT:WHEN & HOW TO ADD IT Salt: When And How To Add It When to add salt. Add salt when indicated on the control panel.The light marked ‘Add Salt’ functions automatically when extra salt is needed. Note that the ‘Add Salt’ light may switch on at any salt level between 3000 and 4000ppm, depending upon the water temperature and mains voltage (see note).This is not a fault but a precaution to ensure that the salt level is never too low.

SOME TIPS ON WATER CHEMISTRY Some Tips On Water Chemistry How to adjust pH. A pH range of 7.2 - 7.6 is ideal for maximum comfort and minimum chlorine demand. Always adjust total alkalinity before adjusting pH. Low pH (acidic water) leads to stinging eyes and corrosion of open metal fittings. Raise the pH by adding sodium bicarbonate or soda ash. Consult your pool professional regarding which chemical is best for your situation and the proper amount to use.
SOME TIPS ON WATER CHEMISTRY Use of algaecides and phosphate removers Although not normally needed, algaecides and phosphate removers may be used in conjunction with a Clearwater chlorinator. Consult your pool professional regarding the presence of phosphates in your local area and always follow manufacturers instructions for treatment. The chlorine residual level automatically maintained by a Clearwater chlorinator is the best defense against algae and is usually all that is necessary.
TROUBLESHOOTING Troubleshooting NOTE: If the chlorinator and pump are running it is normal for a cloud of small bubbles to be produced in the cell, indicating chlorine is also being produced. Problem A Water looks clean but no chlorine residual reading. To test for chlorine residual, switch on the filtration system and adjust the Clearwater to maximum output.After a few hours take a water sample from the pool.Test this water with your test kit. Chlorine residual should measure between 1 and 3 ppm.
TROUBLESHOOTING Problem B Pool green and no chlorine reading. Chlorine is still considered the most effective way of destroying algae and bacteria in your pool water. A chlorine residual of 1 to 3 ppm is considered desirable. REMEDY: Superchlorinate or manually shock the pool. This will raise the chlorine residual to a very high level for a short period of time, and reduce chlorine demand. 1. Superchlorinate with a Clearwater chlorinator: i) Backwash the filter.
TROUBLESHOOTING Problem C Chlorine odor. CAUSE: Not enough free chlorine. Surprisingly, the problem here is not too much chlorine as many imagine. Chloramines form by the bonding of chlorine with amines from sweat and other sources.These chloramines can create a chlorine odor and can also cause eye and skin irritation. Free chlorine does not smell (up to 10 ppm concentration). REMEDY: Same as problem B. Problem D Slimy walls of pool or spa. CAUSE: Combined algae and bacteria growth.
TROUBLESHOOTING Problem G Chlorine Output will not reach maximum - Add Salt light may also be on. CAUSE 1: Low incoming voltage. REMEDY: Confirm Clearwater is wired to 220V. If wired to 220V but incoming voltage is less due to location (rural areas for example), raising the salt level will compensate. CAUSE 2: Salt level below 4000ppm or water temperature is below 65˚. REMEDY: Add salt. (See Salt:When and How to Add it) CAUSE 3: Cell reversing (self clean).
TROUBLESHOOTING Problem I Chlorinator stops working, all lights OFF. CAUSE 1: Unit turned off. REMEDY: Push ON/OFF button. A yellow light in the Chlorine Output indicator window is present when the unit is “ON”. CAUSE 2: Mains power removed or blown fuse. REMEDY: Check mains power source and fuse. Resetting the Fuse. Turn off all power to the Clearwater powerpack.The resettable fuse is located above the powercord on the bottom rear of the LM2 unit.
CHLORINATOR MAINTENANCE Chlorinator Maintenance How to clean your cell. In unusual situations, the self cleaning electrodes may benefit from occasional manual cleaning to remove scale build-up as the result of having very “hard” water or continuous high pH conditions, which can occur with new plaster finishes. 1. Switch off the filter pump and chlorinator, close necessary valves. Note:Always turn pump off prior to installing or removing any Clearwater Cell.
CHLORINATOR MAINTENANCE 4. Mix cleaning solution in a suitable plastic vessel by adding one (1) part of Hydrochloric (muriatic) acid to ten (10) parts water. Note:To avoid splash, always ADD MURIATIC ACID TO WATER rather than water to muriatic acid. Solutions stronger than 1:10 will damage cell and void warranty. Pour the cleaning mixture into the upturned cell housing until the electrodes are completely covered. Allow the cleaning solution to dissolve the calcium deposits for approximately 5 minutes.
