Installation Instructions Indoor Pool Applications ATTENTION For residential indoor pool installations under 130 000 litres use only the Clearwater Salt Chlorinator LM2-15 model. Indoor pools have a very low chlorine demand because of little or no exposure to UV rays which can burn off chlorine from outdoor pools. For this reason only an LM2-15 unit should be installed on an indoor pool. If an LM2-15 is not used, it will be difficult to maintain a proper chlorine level.
Installation Instructions 1. Salt Use refined pure salt (sodium chloride), avoid additives such as iodine. Add salt at the rate of 4 kg per 1000 litres to raise the salt level from 0 to 4000 ppm. For existing pools with a residual of sodium chloride from chlorine use, determine the current level of salt in the pool then add enough salt to raise the level to 4000 ppm. 1 gram per litre (or 1 kg per 1000 litres) raises the salt level 1000 ppm. Refer to Salt Chart for further detail.
Installation Instructions b) c) d) The cell must be horizontal with the unions facing downward. The cell must be level in order for the flow sensor to function properly. Note that the water can flow through the cell in either direction. Glueing: The cell unions are moulded ABS polymer. They can be glued to PVC using PVC cement. First clean both surfaces with solvent cleaner then apply glue to both surfaces. Assemble glued joint and hold in place for at least 30 seconds.
Installation Instructions 5. Connecting to power supply The LM2 is factory set as a 220 volt unit. To operate at 110V, transfer the brown wire on transformer to the 110V side. See inside chassis for directions. Use #12/2 insulated wire and conduit. Connect the power supply wires to the first two terminals. It does not matter which of the two terminals but they must be connected to the two load terminals. (Refer to wiring diagram.) Connect ground wire to ground terminal (fourth terminal).
Installation Instructions NOTE: The Super Chlorinate function will remain active for a total of 24 operating hours after being selected. IMPORTANT: The LM2 should only have power when there is water flow and actuator valves should never block the flow when power is on. Refer to the controller’s installation guide for additional information.

controller operation Controller Operation Startup When switched on, the chlorinator must go through an initialization sequence; this is indicated by the amber LED being illuminated. After a short period the LED will switch off and the chlorinator will begin ‘normal’ operation. First time startup When the chlorinator is connected to the mains for the first time and the initialization sequence has been completed the chlorinator defaults to the ‘zero output’ state.

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.
Operation Clearwater LM2 Series Operation The chlorine production of the Clearwater LM2 is controlled by the number of hours the Clearwater and filtration system are ON, as well as the setting of the output control. The power supply to this unit must be connected to the pump motor switch or automatic timer. The chlorinator functions may only be set when the filtration system is running.
Control Panel Functions Control Panel Functions LM2-24 Display Panel On/Off Button The Clearwater will operate when the pump is turned on. If necessary, the ON/OFF button will switch the LM2 on or 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 Clearwater LM2. Chlorine output is selected by repeatedly pushing this button until maximum is reached on the chlorine output indicator.
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 free chlorine reading of pool water.
Cell Life / Operating Tips Cell Life The expected lifespan of a Clearwater cell when sized and maintained appropriately is approximately 5 years in a seasonal climate. However in conditions where there is a high demand for chlorine (high bather load, poor water chemistry, very hot climate) this lifespan may be reduced.
Operating Tips F. Super chlorinate function The super chlorinate button automatically boosts chlorine levels for a period of 24 hours. During this time it is safe to swim. Superchlorinating should not be part of regular maintenance. Use the function only in situations of increased bather load, or if experiencing trouble (see Troubleshooting section).
Salt: When and 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 salt is needed. Note that the ‘Add Salt’ light may switch on at any salt level between 3000 and 4000 ppm, 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.
Salt: When and How to Add It How to add salt Evenly disperse the proper amount of salt around the perimeter of the pool. Run pump for 4-6 hours. Allow 24 hours for salt to fully dissolve. It will dissolve faster if pump is on. If the ‘Add Salt’ light is on after 24 hours, test salt level and add necessary salt to obtain a 4000 ppm concentration. Even if the salt level is maintained at 4000 ppm, but water temperature drops below 18º (65ºF), the ‘Add Salt’ light may come on. This is not cause for concern.

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 maximum chlorine effectiveness. 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 manufacturer’s instructions for treatment. The chlorine residual level automatically produced by a Clearwater chlorinator is the best defence 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 60% 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 is 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 with sodium hypochlorite. This will raise the chlorine residual to a very high level for a short period of time, and reduce chlorine demand. 1. i) ii) iii) Superchlorinate with the Clearwater chlorinator: Backwash the filter.
Troubleshooting Problem C Chlorine odour 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 odour 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 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 proper wiring with an electrician. This unit is factory set at 220 volts. If your power source is 110 volts the unit must be converted to 110V. See inside powerpack chassis for directions. If the unit is wired properly but incoming voltage is low due to location (rural areas for example), raising the salt level will compensate. Add salt.
Troubleshooting Problem H No Flow light on CAUSE1: Insufficient water flow through the cell. REMEDY: Ensure sufficient water flow through chlorinator cell. Verify that the filter and pump are on. Flow may be restricted if the filter needs backwashing. A pocket of air trapped in the top of the cell confirms low water flow through the cell. WARNING: Operating Clearwater Salt Chlorinator LM2 without water flow through the cell can cause a build up of flammable gases which can result in FIRE OR EXPLOSION.
Troubleshooting Problem J Chlorine level is too high CAUSE 1: Chlorinator is manufacturing too much chlorine. REMEDY 1: Use the output button to reduce setting. Retest chlorine daily until proper level is attained. REMEDY 2: Manually turn chlorinator off until an acceptable chlorine level is reached.
Chlorinator Maintenance Chlorinator Maintenance Winterizing When closing the pool for the winter, perform the following additional steps to winterize your Clearwater salt chlorinator. 1. Turn off the power to the Clearwater at the circuit breaker. 2. Remove the Clearwater cell by unthreading the quick disconnect unions and removing the three wires from the cell.
Chlorinator Maintenance Chlorinator Maintenance 4. Mix cleaning solution in a suitable plastic vessel by adding one part of hydrochloric (muriatic) acid to ten parts water. Note: To avoid splash, always ADD MURIATIC ACID TO WATER rather than water to muriatic acid. Solutions stronger that 1:10 will damage cell and void warranty. Pour the cleaning mixture into the upturned cell housing until the electrodes are completely covered.
