CHLORINE PRODUCTION
The EcoMineral must be run daily to generate sufficient chlorine to sanitise the pool. During Summer this is
approximately eight hours per day, preferably in two periods - between 6.00 and 8.00am and between 5.00
and 11.00pm. Night time is preferable because chlorine dissipates rapidly in direct sunlight. If these running
times are observed, and the Cell is functioning correctly, your pool will have sufficient chlorine when tested in
the morning.
If the level is too low either longer running times are required or the Sanitiser Output Control needs to be
adjusted to maximum. Harsh local conditions such as traffic pollution or wind borne dust require different
running times, in which case, seek advice from your pool shop. During winter approximately 4 to 6 hours
a day should provide enough chlorine. Without sufficient filtration/sanitisation, your pool will never function
correctly.
ALWAYS RUN THE FILTER WHEN SWIMMING IN THE POOL.
In extremely hot weather or during
periods of heavy bathing loads, the running time may need to be extended to 10 – 14 hours per day.
In some cases you may find your chlorine level to be too high. To determine if this is the case, run your
filter/ Sanitiser for the suggested times/chlorine production level and test your pool water on the morning
after operation. If your chlorine test shows a high level of chlorine, either the running times can be reduced
slightly, or the Sanitiser Output Control can be turned anti-clockwise. Test your chlorine level again the
following morning at around the same time. If your chlorine level is still high, repeat the above process until
the correct level is attained.
“SHOCK” TREATMENT
Periodically, especially during extremely hot conditions, it may be necessary to boost the amount of chlorine
in your pool in order to maintain absolute sanitation of the water. This can be achieved by adding either
liquid or granulated chlorine. If granulated chlorine is added, the Cell must be checked regularly, since the
additives from this product will clog the electrodes. Alternatively, extend the running time of your EcoMineral.
CHLORINE TYPES AND COMPARISONS / MAX POOL SIZE
Many Sanitiser manufacturers calibrate their units to compare with 65% granulated chlorine, making it
necessary to adjust their readings to a lower level in order to determine true chlorine production. Below is a
comparison table of the available types of chlorine used to sanitise pools.

NOTE: The appropriate Sanitiser size for your pool is dependent on the local
climate and the bather load of the pool. Please note that Sanitiser cell life
can be increased with shorter running times during winter and lower output
settings. Davey recommends that a Sanitiser is run for between 6 - 8 hours a
day during summer, and 4 hours during winter.
