CELL LIFE / OPERATING TIPS

Cell Life

The expected lifespan of a Clearwater cell when sized and maintained appropriately is ap-

proximately 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 re-

duced. When replacing the cell, only use replacement cells having a label that clearly states that

it is a replacement cell for the chlorine generating device of the Clearwater Salt Chlorinator

LM2 Series REGISTRATION NUMBER Model LM2-15 27850, LM2-24 27580 or LM2-40 27851

PEST CONTROL PRODUCTS ACT. The model name can be found on the power pack.

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, the filtration system may be run over a shorter period of time. Shorter

periods will help to lengthen the life of the cell electrodes.

B. Chlorine output settings

Start operation of the Clearwater LM2 at maximum output. Add salt to the pool if the ‘Add

Salt’ light is showing. Add 1 gram of salt per litre to raise the salt level by 1000ppm. Refer to

‘Salt: When and how to add it’ and the salt chart. Do not operate the Clearwater until all the

salt has dissolved as this will cause damage to the unit.

C. Free (residual) chlorine reading

The free chlorine residual in the pool should be between 1- 3 ppm. Increasing the daily operat-

ing period of the system increases the free chlorine reading, and a shorter operating period

reduces the chlorine reading. Likewise, operating the chlorinator at maximum output will

produce a higher chlorine reading than operating the chlorinator at a lower setting.

D. Chlorine stabilizer (cyanuric acid) level

The chlorine stabilizer (cyanuric acid) reading should be between 30-100 ppm. This will

vary depending on your regional climate. Chlorine stabilizer helps to keep a satisfactory free

chlorine reading in hot sunny climates. Extremely hot and sunny climates will require readings

at the higher end on the given range. Refer to stabilizer chart. Cyanuric acid prevents rapid

destruction of chlorine by the sun’s rays. Regulations may exist regarding the use of cyanuric

acid; please consult your local authority. NOTE: Cyanuric acid is not needed for indoor pools.

E. pH readings

It is ABSOLUTELY ESSENTIAL that the pH of the pool be maintained in the range of 7.2 – 7.6.

The effectiveness of chlorine as a sanitizer is significantly reduced as the pH rises. At a pH of

8.0 nearly all of the chlorine being added to the pool is ineffective, and it will be almost impos-

sible to maintain a satisfactory free chlorine reading. Overchlorinating will cause an increase in

pH. Maintain a chlorine level of 1-3 ppm and do not superchlorinate unless necessary.
