General Information - Davey PoolFresh Installations- Und Betriebsanweisungen

The PoolFresh chlorinator must be run daily to generate sufficient chlorine to sanitise the pool. During
Summer this is usually minimum 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 output % needs to be increased. Harsh
local conditions such as traffic pollution or windborne dust require different running times; in which case,
seek advice from your pool shop. During Winter and Spring approximately 4 to 6 hours a day should provide
enough chlorine. Without sufficient filtration/chlorination, 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/chlorinator 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 output % can be decreased. 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.
SUPER - CHLORINATION
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
PoolFresh chlorinator.
