by a proper color measurement method (e.g. Poollab ZWMX1060
Key elements :
○ Incomplete grounding of the pool pipes can have negative effects on the measurement results
and thus lead to abnormal pH and chlorine values in the pool.
○ Proper grounding is made as follows :
- The pool line after the filter pump is grounded through an in-line grounding to an
independent grounding post
- The pool line near the measuring probes is grounded through an in-line grounding to a
second independent grounding post
- Use only city water, not rainwater or well water

Installation
Attention!
○ The electrical installation should be done in such a way that:
- The electrolysis and acid pump cannot operate if the filter pump is not working.This can be
done by adding a flow switch/flow controller ZWMX3552-P to the installation or by using the
same power line as the filter pump.
○ Addition of pool chemicals should be done downstream of pool accessories such as heater, UV
lamp, filter etc.
○ It is recommended that the installation of the water treatment unit be in bypass configuration.
○ Install the water treatment unit on a solid base or against the wall (always vertical)
○ The product must be installed inside. If you want to do this outside, please contact your supplier.
○ The electronics (dosing devices) of the unit must be installed inside. Make sure that - in case of
leakage - the water cannot run over the installation.
○ The electronics or the device itself must NEVER be connected to an output of a frequency
converter or frequency inverter.
○ The dosing device must not be on the same power circuit as that of the frequency converter or
frequency inverter being used and it must be at least 3 m away from the dosing unit.

Salt electrolysis installation
The salt chlorinator should be installed with the return line to the pool and through the water
treatment line as shown in the diagram. A control valve must be installed on the main line.
Before installing the salt chlorinator, make sure that the water flow matches the direction indicated
by the chlorinator.
To connect the pipes, use only line suitable for PVC bonding.
The chlorinator should be installed in a well-ventilated area to allow it to cool properly.
Do not install in an area where the electronic components of the chlorinator may be damaged by
moisture or rain.
During operation, the chlorinator should avoid direct sunlight to prevent the aging process of the
housing.
Make the electrical connections in such a way that:
- The salt electrolysis and acid pump cannot operate when the filter pump is not working.
- The salt electrolysis and acid pump can be turned off when the filter pump is operating.

The chlorinator's external power adapter must be connected to a power source that has a 30mA
ground fault circuit breaker
Preparing the pool water
Make sure the pH of the pool water is at least between 7.2 and 8.5 and as close to 7.4 as
possible. Make sure the content of chlorine stabilizer (cyanic acid) in the pool water is
between 20-40 ppm (20-40 g / 10 m³)
Chlorinator
The Salt Chlorinator uses the most advanced microcomputer technology. It is both
multifunctional and easy to operate.
It includes features such as automatic reset (self-cleaning, lime removal) and malfunction
alarm.
Product Distinctive Facts:
Design for easy access to the titanium polar plate during installation and maintenance
Users can choose from different levels of chlorine production. One can adjust the level
according to the need of the pool, which is energy efficient and environmentally
friendly.
The chlorinator includes a salt meter and alarms.
The chlorinator includes water temperature protection (10 ° to 40 ° ). This can significantly
improve the life of the unit. Outside this temperature range, the electrolysis does
not work.
There is a water level detection. The chlorinator will only operate if water is effectively
detected.

Using the chlorinator
1. When the chlorinator is connected to the faucet, adjust the water flow with the valve to ensure
that enough water flows through the salt chlorinator.
2. Before use, ensure that the salt concentration of the pool water is within the normal operating
range (3.5- 4.5 kg of salt per m³), otherwise it may shorten the life of the Titanium cell.
3. The display shows the current water temperature. Press the Power / Operate button, the
operation light will change from red to green and the chlorinator will start working: Note: The
chlorinator can only operate if the water level detector detects the presence of sufficient
water flow .
4. By pressing the "+" or "-" button, users can adjust the rate of chlorine creation as needed; users
can use level 1-5, 1 level is the smallest and 5 level is the highest. The higher the level, the
faster the chlorine is produced.
5. Parameter check: press the acceleration key several times while the chlorinator is off to look up
various parameters below:
① Internal temperature chlorinator
② Water temperature
③ Input voltage
④ Version number
⑤ Time period of continuous operation; the system automatically exits the application after
3 seconds
6. Time setting for continuous operation: press the acceleration key 5 times while the machine is
turned off to display the time period of continuous operation. Change the time periods of
continuous operation by pressing '+' or '-'. The time period ranges from 1-24 hours
(and then shut off) after it is turned on. After this cycle, the chlorinator stops for 12 hours and
turns on again for 12 hours.
In case you use the control option "RX TIME", the setting of the chlorinator should be at least as
long, than the selected time.
IMPORTANT: THE CHLORINATOR IS PRESET FOR 12 HOURS CONTINUOUS
OPERATION, IF 24 HOURS NON-STOP OPERATION IS REQUIRED, THE TIME
FOR CONTINUOUS OPERATION MUST BE SET TO 24; THE SYSTEM WILL
AUTOMATICALLY EXIT THE SETTING AFTER 3 SECONDS.

Additional : operation and maintenance of the chlorinator
1. The mixture and maintenance of water and salt The operational state and maintenance
of salt chlorinator
1.1 The calculation of the amount of water:
Knowing the capacity of the pool is the first step in adding salt to the pool .
Rectangular pool : length (meter) x width (meter) x average depth (meter) = pool water
capacity ( cubic meters)
Round pool: diameter (meter) x diameter (meter) x average depth (meter) x 0.785 = pool
water capacity (cubic meters)
Oval pool: length (meter) x width (meter) x average depth (meter) x 0.893= pool water
capacity (cubic meters)
1.2 The type of salt
The salt used must be "pool salt" with approval number as a precursor of biocides of the
country in which the unit is used. The sodium chloride (NaCl) in the salt must be at least
99.6% .
1.3 Adding the right amount of salt:
Most swimming pools contain a certain amount of salt, the concentration of salt in the
water depends greatly on the water source. Users can use a portable NaCl tester or a
salinity pen to test the current salt concentration of the pool.
TIPS
The normal salt concentration level of the EC Series of salt chlorinator is 3500-4500 ppm
(3.5-4.5 kg of salt per cubic meter of water)
When you first start using the EC Series, add salt to the pool according to the steps below:
A) Use a salinity meter to check the initial salt concentration in the pool.
B) Add the appropriate amount of salt, making sure to add 3.5-4.5 kg of salt for each cubic
meter of the pool.

1.4 The correct way to add salt:
A) Turn on the pool circulation pump and allow the water circulation to begin.
B) Turn off the chlorinator.
C) Test the current salt level of the pool.
D) Calculate the amount of salt needed to add to the pool.
E) Add salt to the pool around the side of the pool, allowing the salt to dilute quickly and
evenly in the water. Do not allow salt to accumulate at the bottom of the pool. If necessary,
stir the water at the bottom of the pool to allow the salt to completely dissolve.
F)Run the circulation pump for 24 hours to allow the salt to distribute evenly in the pool.
G)24 hours later, test the salt concentration of the pool again to see if it has reached the
optimum level.
H)When the pool salt concentration has reached the desired level, turn on the salt
chlorinator and other equipment. Once the chlorinator has started, set the desired level of
chlorine production.
1.5 Reduce the salt concentration:
The only way to lower the salt concentration is to drain some of the pool water and replace
it with fresh water.
1.6 To reduce the loss of chlorine due to UV radiation on the water of the outdoor
pool, you should add Cyanuric acid of 20-70 mg / l as a chlorine stabilizer.
2. Maintenance of saltchlorinator
2.1 Maintenance of the electrolysis cell
To ensure proper operation of the salt chlorination plant, the electrolysis cell should be
checked every three months after cleaning the filter. Follow the steps below to complete
the check:
A) Before removing the electrolysis cell, close the inlet and outlet valves and turn off
the salt chlorinator for 5-10 minutes.
B) After removing the electrolysis cell, check if there are flaky sediments, debris,
light-colored layers in the inner surface. Clean carefully with clean water .
C) If there is a white calcified substance on the titanium plate, immerse the titanium
plate in 4: 1 water hydrochloric acid to remove the calcified substance. For your safety, wear
rubber gloves and eye protection.
D) If there is significant sediment that cannot be removed on its own, contact the
seller for professional advice.
