Salt is NOT used up in the process of producing chlorine or by evaporation. Salt is only lost through back -
washing, splash - out, overflow or by leakage from the pool or plumbing. Heavy rain can dilute the salt solution in
your pool; therefore salt levels should be checked during this season.
Low salt levels will destroy the coating on the Anode plates and will void all Warranty.
The EcoSalt
™
has a built in warning indicator to minimise damage resulting from insufficient salt levels, however,
the ultimate responsibility is on the owner to ensure adequate salt levels are maintained all year round.
4. RUNNING TIMES:
These instructions cover EcoSalt for residential use only.
If you run your chlorinator for 24 hours a day, or for long periods, the Cell life will be greatly reduced. It is
important that the correct model EcoSalt
™
has been installed on your pool. Many models are available from Davey
to cope with small courtyard pools up to commercial applications. (Consult your local EcoSalt
™
Dealer for more
information).
Note: The EcoSalt guarantee does not apply to commercial or semi-commercial installations, i.e. where the
system runs more than an average of 8 hours per day over the year. Guarantee on commercial and semi-
commercial installations is 12 months only on both power supply and cells.
CHLORINE PRODUCTION:
The EcoSalt
™
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/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 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 EcoSalt
™
.
CHLORINE TYPES AND COMPARISONS / MAX POOL SIZE:
Many chlorinator 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.
