9. CHLORINE PRODUCTION
The Henden Chlorinator 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 PUMP 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.
9.1 “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 Henden Chlorinator.
9.2 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. Henden recommends that a
sanitiser is run for between 6 - 8 hours
a day during summer, and 4 hours
during winter.
