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.
