PRODUCT SUMMARY
Salt chlorinator uses the most advanced microcomputer technology. It is both
mu l t i-fu n ctio n al a n d ea s y to ope r ate. It c onta i n s f u n cti o n s s u c h a s se l f -
cleaning malfunction alarm. You can set the to match and chlorine production
your need, to achieve the goal of efficiency and environmental friendliness.
Product distinguishing features:
1. Controller and the chlorinator are integrated for easier installation and more
space-saving.
2. Water inlet and output are designed on the same axis to decrease the need for
pipe arrangement.
3. Design for easy access to the titanium polar plate for simple installation and
maintenance.
4. Users can choose from different levels of chlorine production. Can alter the
level according to need, which is energy efficient and environmental-friendly.
5. Thechlorinatorcontains salinity level prompt and malfunction alarm.
6. Thechlorinatorcontains water temperature protection (10° to 40°) and water
shortage protection. This can effectively extend the service life of the
machine.
7. Water level detection. The chlorinator only operates when the sensor detects
the presence of water.
8.When powered-on automatically initiates the last work setting from system
memory.
WARNING
Automatic power on means when power shortage occurs during operation,
and when power recovers the system automatically turns on.
Memorizing the setting from last operation means the condition before a
power shortage, or the system setting before a system failure, including the
“ ” state, the “ ” state timer is reset. Boost Boost

WARNING
A.Please do not use rock salt, its impurity may shorten the service life of the chlorinator.
B.Do not use Calcium Chloride as salt, only sodium chloride can be used.
C. Avoid using anti-blocking agent (sodium cyanide, aka YPS, is poisonous and corrosive)
salt, this kind of salt may change the color of the pool surface and the equipments inside.
D. Can use water treatment salt pills, but it make take very long to melt in the water.time
1.3Adding the right amount of salt
Most pools contains certain amount of salt, the concentration of the salt in water
will vary depending on the water source and the sterilizing agent used. Users can
use hand-held NaCl tester or salinity pen to test the current salt concentration of
the pool.
TIPS
♦ The operating salt concentration level of the salt chlorinator EC series is 3500ppm best
(3.5kg of salt per ).cubic meter
♦ When operating the salt chlorinator EC series for the first time. Add salt to the pool following
the steps below:A.Use a salinity meter to check the original salt concentration in the pool.
B.Add appropriate amount of salt , ensure that for each add 3.5kg of salt.cubic meter water
♦ The concentration of salt (ppm value) can be seen as the gram of salt within 1 ton of water. If the current
salt concentration of a 100 M3 pool is 850ppm (can be as 850g in 1 ton of water), how much taken
salt is needed for the chlorinator to normally operate ?
♦ Salt need to be added(unit: gram) = water in the pool x (normal operation salt concentration – the
current pool salt concentration) = 100 x (3500-850) = 265000 gram.
a.Turn on the circulation pump of the pool, and let the water circulation begin.
b.Turn off the salt chlorinator.
c.Test the current salt concentration of the pool
d.Calc ulate the amo u nt of s alt ne e ded to add to the poo l ac c o rdi n g t o th e
corresponding chart.
e.Add salt to the pool around the side of the pool, so that it can quickly and evenly
dilute into the water. Do not let salt accumulate on the bottom of the pool. Stir the
water on the bottom of the pool if needed so the salt can completely dissolve.
f.Run the circulation pump for 24 hours, so the salt can evenly distribute in the pool.
g.24 hours later, test the salt concentration of the pool again to see if it has reached
optimum level.
h.When the salt concentration of the pool has reached the desired level, turn on
the salt chlorinator and other equipments. Once the chlorinator initiates, please
set your desired level of chlorine production.

2. The maintenance of salt chlorinator
2.1 The maintenance of the electrolysis cell
To ensure the smooth operation of the salt chlorinator, the electrolysis cell should
be checked every three after cleaning the months or filter, whichever comes first.
Follow the steps below to complete the check:
A.Before removing the electrolysis cell, close the inlet and output valve aftershutdowm
the salt chlorinator for 5 – 10 minutes.
B.After removal of the electrolysis cell, check to see if there are flake-like sediments,
debris, light colored layering in the inner surface. Wash with clean water.
C.If there are white calcified substance on the titanium plate. Submerge the titanium
plate into 4:1 water hydrochloric acid to remove the calcified and solution
substance. Please wear rubber gloves and eye protection for safety.
D. If there are major sediments that cannot be removed on one’s own, please contact
the seller for professional suggestion.
1.5 Decrease the concentration of salt
The only way to decrease the concentration of salt is to drain a part of the pool’s
water and replacing it with fresh water.
