Commercial Salt Chlorinator | Installation & Operation Manual
5.5 Operation
CAUTION
Before attempting to operate, refer to the
Pool Water Preparation
part
of the
New Installation
section. Also, do not adjust chlorine production
above 00% until it is certain that salt has been dissolved in pool.
Operating without salt will damage the electrolytic cell.
NOTE:
The chlorinating system only operates when the
pump is running. During hot weather months you
may need to increase pump run time to allow
sufficient chlorine production.
Try initially setting the pool pump run-time to 12
hours per day. It will take a few days to get just the
right pool pump operating time.
The key points are:
–
Check chlorine level on a regular basis
and adjust the chlorine production rate (%)
accordingly.
–
Operate pool pump at least the minimum time
needed for good filtration.
–
The pool pump timer reduces energy
consumption.
NOTE:
Exception - for cold weather operation:
If the salt water chlorinator is set to run 24 hours
a day through the winter, extremely cold water
temperatures can contribute to a reduction in the
operating life of the electrolytic cell. Sometimes
it will be necessary to run the chlorinator at a
very low production rate (10-20%) or to turn the
unit off.
5.6 Start-Up
5.6.1 Shocking
Shock (superoxidation) the pool water from an
outside source at the time of pool startup to
burn off contaminates. During normal operating
conditions the chlorinator is capable of generating
a sufficient level of chlorine for sanitation within
several hours. However, if the pool water has a high
chlorine demand due to startup conditions then
the chlorinator will not be able to produce enough
chlorine to reach break-point chlorination. Shocking
involves the manual addition of chemicals to quickly
raise the level of chlorine. When the chlorine level is
quickly raised to 5 – 15 ppm the pool water is said
to have been shocked Wait until the chlorine level
has returned to 1 - 3 ppm before turning on the salt
water chlorinating system.
5.6.2 Apply Power
1. Check that the filter is 100% clean, and ensure
that the swimming pool and the installation do
not contain copper, iron or algae. Ensure that
any heating equipment on the pool is suitable
for use in salt water.
2. Ensure that the swimming pool water is
balanced, because like that the chlorine
produced is used more efficiently and effectively,
and ensures that the life of the electrodes is
prolonged, as well lower scale build-up in the
pool. Water should be maintained within the
parameters shown below.
–
pH must be in the range 7.2-7.6
–
total alkalinity must be in the range
0.059-0.12 ppm
3. Although the electrolysis system can operate
within a salinity range of 4–6 g/l, the minimum
recommended level of salt, 5-6 g/l, should be
maintained adding 5-6 kg per m
3
of water if
the water did not previously contain salt. In the
case of LS models, the range of recommended
salinity is 2 g/l. Always use common salt
(sodium chloride), without additives like iodides,
that is “apt for human consumption”. Never
add the salt through the electrolysis cell. Add
it directly to the swimming pool or into the
balance tank.
4. When adding the salt, and in case the swimming
pool is going to be used immediately, carry out a
treatment with chlorine. An initial dose of 2 g/m
3
of trichloroisocyanuric acid may be added.
5. Prior to starting up the salt chlorinator,
disconnect the power supply to the salt
chlorinator and run the pump for 24 hours to
ensure that the salt is completely dissolved.
6. Next, reconnect the power supply and turn on
the salt chlorinator, locating the production level
so that free chlorine concentration stays within
the recommended range (0.5 - 1.5 ppm).
NOTE:
In order to establish the free chlorine level you will
need to use a test kit.
7. In outdoor swimming pools it is advisable
to maintain a level of 50-75 ppm of chlorine
stabilizer (cyanuric acid) in the water. This will
help to stop the chlorine that is in the water from
being destroyed by the sun.
