Waterco Electrochlor LCD Chlorinators
Electrochlor Salt Water Chlorinator
The Electrochlor will automatically maintain the chlorine level of your pool and eliminate problems
associated with periods of very high or low chlorine levels. Fewer uctuations in chlorine levels
mean fewer uctuations in pH levels. This adds up to more stable, balanced water.
Consistently maintained sanitizer levels in the pool water will prevent the growth of all common
algae. A salt-water chlorinated pool requires much less attention than a chlorine pool.
Chlorine Generation
A small amount of natural salt is dissolved into the pool water. As the pool water ows through
the electrolytic cell, electrolysis separates the salt water into its basic components, sodium and
chloride. Pure chlorine gas is produced by this process and goes to work in the pool. Following this
process the chloride and sodium re-bond and become natural salt again.
Electrochlor
Electrochlor consists of a Power Pack (to supply power to the cell) and Salt Cell (where the chlorine
is produced).
Electrochlor Power Pack
The Power Pack monitors and controls chlorine production by regulating the amount of electrical
energy supplied to the salt cell.
In built pool monitor
Electrochlor’s power pack has an inbuilt:
• Salt level indicator
• Chlorine production indicator
• Self diagnostics

Pump Protection
If no water ow is detected in the salt cell, Electrochlor automatically switches off the pump to
prevent any damage to the pump and pool equipment. Indicators “FL” will start blinking on the
LCD panel to alert the pool owner, until the fault is rectied.
Electrochlor Salt Cell
Self-Cleaning
Electrochlor Self Clean Salt Cell has the added ability to reverse the polarity of the voltage to clean
calcium build up off its electrodes.
The Electrochlor’s electrodes, the anode and cathode and hold an electrical potential difference
between them for a designated period of time. This difference is reversed after that period of time
has expired and then the anode becomes the cathode and the cathode becomes the anode.
The reversing of polarity or electrical potential difference will then start to remove any calcium
build-up, which may have been deposited onto the cathode.
This continuous reversing of polarity will keep the cell clean from calcium deposits during its
operation, providing the chemical balance and ow of the pool water thru the cell is maintained
within normal parameters.
It is recommended that you obtain regular water chemistry tests from your local pool professional
to ensure your water balance is within range.
The Electrochlor chlorinators must operate between the salt level ranges listed below.
SALT LEVELS
MINIMUM = 5000 ppm OPTIMUM = 6000ppm MAXIMUM = 6500ppm
Testing kits are available from the local pool professional and should be used to accurately check
the salt levels in the pool water.
The Electrochlor’s salt cell consists of a series of titanium
electrodes with opposite charges. Electrochlor’s clear
salt cell housing allows visual inspection of the salt cell
plates and enables monitoring of chlorine production.
The cell housing is constructed using clear U.V.
stabilized acrylic. Both anode and cathode of the
self-clean chlorinator are made from uniquely coated
titanium mesh to add extra durability and life.

Installation
1. Ensure that the chlorinator cell is the last piece of equipment installed on the ltration system
– this is so the chlorine produced will not damage other equipment such as heaters.
2. The cell may be installed above or below water level. If it is below water level, please ensure that
an isolation valve is installed so the unit can be serviced without losing water from the pool.
3. The cell may be mounted on different angles so long as a gas trap is provided.
GAS TRAP: The cell must be positioned in such a way as to provide a gas trap. The bottom
of the cell must be above the top surface of the pipe from the previous piece of equipment,
as per the below diagram.
Installation as indicated will prevent the hydrogen
gas (a bi-product) of the electrolysis process to
collect in the lter should scavenging water ow
cease.
HOW TO ADD SALT
After installing your salt chlorinator, you simply add the recommended amount of salt to your pool
and choose your desired chlorine level.
1 kg of salt in 1,000 litres of water raises the salt level by 1000ppm. Therefore, 420 kgs of salt will
raise a 70,000 litre pool from 0 ppm to 6,000 ppm.
Do not add the salt to the skimmer box. Run the lter for 4 to 6 hours to help disperse the salt
around the pool. Note: allow 24 hours for the salt to fully dissolve.
WHAT TYPE OF SALT SHOULD I USE?
High purity salt, it is important that the salt does not contain additives. Any common salt (like table
salt) usually has an additive that may have staining properties.

Maintenance
Although the Self-Cleaning chlorinator is designed to greatly reduce the need to clean the salt
cell plates, inspection and removal of small calcium build up will be periodically required to insure
correct performance.
Salt Cell Cleaning Procedure
1. Press the ON/OFF button on the power pack to turn the pump
and Electrochlor to standby mode.
2. Unscrew the barrel unions from the salt cell and disconnect
the cables from the salt cell’s brass connectors.
3. Turn the salt cell housing upside down with both ports facing
upwards.
4. Pour the Cell Wash cleaning solution into the housing to dissolve the calcium build-up from the
salt cell plates. There should be just enough solution to cover the salt cell plates.
5. Allow enough time for the solution to dissolve the calcium build-up from the salt cell plates.
Approximately 5 to 10 minutes.
6. Once the calcium build-up has been removed, pour out the Cell Wash solution into a bucket
and lightly rinse-off excess calcium and Cell Wash solution from the salt cell assembly, with
fresh water.
7. Reconnect the salt cell onto the lter system.
8. Press the ON/OFF button on the power pack to reactivate the pump and Electrochlor.
Never use products that are not specically manufactured to clean the Electrochlor’s salt
cell. Do not use raw acids such as hydrochloric acid. This will damage the salt cell and
severely shortens its life and will void warranty. Please consult your local pool professional
for advice on salt cell cleaning products.
Advanced Programming
Program the chlorinator timer to turn on or off at any time that suits your lifestyle. 7 Day timer
allows for settings on week days, week ends, any day or every day operation. 3 program settings
are available.
You can program the Electrochlor for extra chlorination during the weekends and less chlorination
during weekdays.
Electrochlor’s operation modes are controlled by UP or Down keys. You can scroll through the
following operation modes.
TIMER – to run as programmed.
MANUAL – to run non stop.
OFF – to switch chlorinator off.

Chlorine Production Levels
The output of the chlorinator can be adjusted to reect the different seasonal requirements in order
to maintain satisfactory chlorine sanitizer levels.
The amount of chlorine produced is displayed by a bar graph, which can be adjusted by pressing
the SET Level key and then by pressing the UP or DOWN keys and pressing the ENTER key to
conrm.
When chlorine production is set at 100%, the Bar Graph will be shown in full in the LCD display with
correct water balance. Each segment on the bar graph represents 10% of chlorine production. The
total bar graph is made up of 10 segments
If the pool water is over chlorinated, simply reduce the chlorine production set level.
Note: Chlorine production level should be turned down during lter’s backwashing and
rinsing cycles, to stop the pump from cutting out prematurely.
SALT light ON
As the salt level drops, the SALT light will come on at any salt level between 4500ppm and 5500ppm
depending on mains voltage and water temperature. A water temperature of of less than 20°C may
trigger the SALT light to come on. During periods of low temperature, if the SALT light is on, take a
water sample to your pool shop to test the salt level of your swimming pool.
If the Salt light is on during periods of high temperature it is advisable to empty no more than two
25 Kg bags of salt at one time into the shallow end of the pool. The salt will slowly drift down to the
deep end, helping to disperse the salt.
Observe the chlorinator pool monitor and conrm the SALT light is not showing. If the light remains
on, wait 24 hours and repeat the procedure with a further two bags of rened salt.
Note: Operating the Electrochlor at reduced salt levels may shorten the life of the electrode.

Self Diagnostics
The Bar Graph and “ F ” symbol indicates the following conditions:
• F0 - The salt level may have fallen below the required level.
• F0 - There is too much calcication on the salt cell plates for
programmed chlorine production level.
• F0 - The pool water temperature is lower than 15° C.
• F1 – When the current can only reach 50% of set chlorine production level.
This condition indicates that one SCR (Silicon-Controlled Rectier ) is not working.
• F2 – The salt cell requires replacement.
• FL – No ow of water is present in the salt cell or a sensor wire has broken or the
pump is not working or connected.
Note: The microprocessor on the chlorinator will hold its memory if there is a power
interruption, ensuring that when it is turned on again, the operating sequence of the reverse
cycle is maintained.
Time Clock Operation
When the Electrochlor is set to TIMER, the timer
will activate both the pump and chlorinator,
as programmed.
