SALT WATER CHLORINATORS – INSTALLATION INSTRUCTIONS
An introduction to salt water chlorination.
• Salt water chlorination is the healthy alternative to chlorinating your swimming
pool, the natural way.
• Very simply, coarse salt is added to your pool to form a mildly saline solution.
• The salinity is kept at a pleasantly comfortable level, being typically one fifth or
less than that of sea water.
• The system works by producing chlorine in the unique SALINE BLUE cell in low
concentrations whenever the pump and filter is running, and as the filter runs
for many hours of the day, the pool's total chlorine demand will still be met,
even at these low concentrations.
• With the SALINE BLUE system, chlorine is produced by electrolysis of the pool
water as it flows through the cell and returns to your pool.
• A major advantage of the SALINE BLUE system is that the chlorine produced in
the cell has no effect on your pool's pH, total alkalinity or calcium hardness,
which is not the case with other chlorination methods, making it easier and less
costly for you, the pool owner, to keep your water in balance.
• By automatically chlorinating your swimming pool this way, many of the
problems associated with other chlorination methods, are eliminated.
• The process is safe, effective, economical, and healthy and requires only
minimum maintenance.
Introduction to the Saline Blue Cell
• Ease of installation - unions both ends.
• Improved linear water flow within the cell.
• Lower replacement costs.
• Extended cell life with no knife edge erosion.
• Virtually Zero maintenance.
• Clear housing allows easy monitoring of electrodes & chlorine production.
• Cell housing withstands in excess of 4 bar under test.
• Inline water strainer prevents particles lodging between plates.
• Pro-active water environment monitoring for optimum Chlorine output & cell
life.
• All top quality titanium parts, fully serviceable cell.
The Saline Blue Power Pack
• Power Supply efficiency better than 80%, resulting in reduced electricity costs
and longer equipment life.
• All aluminium enclosure for light weight, corrosion resistance and heat
dissapation.
• Compact, easy and quick to fit, saving time and money.
• Easily accessible, the enclosure is easily mounted onto walls, or within pool
boxes, and needs only one posi screw removed to expose enclosure interior.
• The control box is easily mounted on two screws or bolts which are
predetermined on a tear off section of the packaging box. Once these are fixed
the control box simply clips on.
• Short circuit and overload protected - cannot be damaged by overdosing with
salt.
• Automatic salt concentration and cell function monitoring.
• Fixed current output, timer controlled, allows chlorine output to be accurately
adjusted even for very small pools while ensuring maximum cell life.
• Soft-start capability to protect electrode coating at switch-on and at polarity
reversal.
• Advanced reversal circuitry which:
- Remembers its 'run' status even without power
- Ensures maximum electrode protection during the reversal sequence
- Monitors pool water environment to maximise Chlorine production & cell life.
- Should water environment be detrimental to cell life, the unit will shut down.
Typical Installations
The Saline Blue Salt Chlorinator Control Box
1. Mount the control box vertically, preferably out of direct sunlight and out of the
direct path of any irrigation system. Make sure any plant room or filtration box
is well ventilated so as to avoid condensation, especially if other chemicals are
also stored in it. Chemical fumes are corrosive!
2. The 'A.C.' mains cable must be connected to the output of the pump timer or
wired to the pump motor. This must be undertaken or authorized by a
registered electrician.
3. Failure to install the control box as per the aforementioned paragraph may
invalidate your warranty.
4. The chlorinator "earth" lead (green / yellow) must be connected to the "earth
bus" inside the distribution board, or in accordance with the earthing
requirements of the relevant local authorities, if specifically required.
The Saline Blue Salt Chlorinator Cell
1. Install the cell as shown in the accompanying diagrams using the pipe work to
create a 'gas trap'.
2. Ensure the sensor is always positioned at the top, if installed vertically or
horizontally.
3. The cell must be installed as the last piece of equipment in the pool return line,
i.e. downstream of any receptacles, pool heaters, solar heaters and other
equipment.
4. If the cell is installed below the pool water level, isolating valves should be fitted
at both sides of the cell.
Salt requirements and calculations
• High purity salt is recommended.
• Iodated salt is
NOT
suitable.
• Always remember: higher salt concentrations = longer cell life and higher
chlorine output.
• Lower salt concentrations = reduced cell life and poor chlorine output.
• The transition between 'salt low' and 'salt ok' is set to occur below 0,4%. Always
keep your salt levels above 0, 5% for best performance.
Adding salt to your pool
• Adding salt may be needed from time to time to maintain an optimum salt level.
• Use a salt test strip to determine the salt level in the pool water prior to adding
any salt, or ask your local pool shop to test it for you.
• Use the table below to calculate the quantity of salt required to adjust the pool
salt concentration.

• When adding salt, place the unopened bags on the stair area of your swimming
pool, with some black refuse bags underneath them to prevent staining.
• Check salt levels once a month, more frequently in rainy weather, and adjust
accordingly.
Saline Blue Control Box Operation and Settings
POWER ON Light:
The power pack controller is receiving power.
CELL ON Light:
The cell is receiving power.
SALT LOW Light:
Add salt now to ensure adequate levels of chlorine are produced and to avoid
shortening the life of your cell.
CELL PROTECT Light:
This light will come on in combination with the "salt low light" and indicates improper
water environment which could be detrimental to the cell. Perform the following checks
in sequence to find the cause of the fault:
• Check that the cable connections to the cell are tight, clean and that the cables
are not damaged.
• Have your salt levels tested at your nearest pool shop and if low, add the
required amount of salt to bring the level up to above 0,5%. If your cell is still
serviceable the "cell protect" and "low salt" lights should go off and normal
chlorinator operation should ensue. If the red lights stay illuminated with
adequate salt levels in the swimming pool, then the cell requires replacing.
• If the Saline Blue chlorinator is operated in unfavorable conditions the cell
protect and salt low light will light up and the unit may switch off.
Check your chlorine residual levels periodically to ensure your swimming
pool is being adequately sanitised. Chlorine levels should be kept in the 1
- 3 ppm range. Adjust the output select up or down accordingly.
Suggested filtration run cycles
• Saline Blue recommends operating your chlorinator for two cycles per day (an
early morning and late afternoon cycle). These cycles are especially necessary if
the swimming pool is not stabilized. Depending on the season, bather load and
sunlight exposure, each cycle could vary from 3 - 6 hours, i.e., a total of 6 - 12
hours or more per day.
• If it is necessary to operate the Saline Blue salt water chlorinator only during the
daytime, then the addition of stabilizer is recommended.
• In winter, a single daily cycle of 3 - 5 hours should suffice.
In extremely hot climates, or during periods of unusually hot weather, it
may be necessary to super-chlorinate your swimming pool once every 2 -
4 weeks. Contact a local pool dealer, or email us for further information.
In unfavorable conditions, detrimental to the cell life, the unit may switch off. When
conditions are again favorable the unit will automatically switch on.
Cell maintenance and cleaning
The Saline Blue salt chlorinator cell incorporates a molded-in strainer at the inlet to
prevent any debris that may enter the cell, from fouling the electrodes.
As the cell is molded from clear plastic, it is easy to inspect the strainer visually.
Inspect the strainer periodically and clean when necessary.
To clean your cell:
Turn off pump and SALINE BLUE chlorinator, and turn the multiport valve to the
"closed" position.
To remove the cell:
Unscrew the two unions and remove the cell assembly. It should not be necessary to
disconnect the cables. Carefully remove any debris from the strainer, by hand, or by
flushing with a hosepipe. If a hosepipe is used, and the cables have been disconnected
from the cell, take time to seal off the cable connections so that they do not get wet.
To replace the cell:
Make sure all contact surfaces are clean and that o-rings are present, then replace the
cell in the swimming pool return line. Refit the cell power cables if they have been
disconnected. If the chlorine output has been set to the "OFF" position, reset to the
position prior to cleaning. Turn the multiport valve back to the "filter" position.

Regular pool maintenance checks
Weekly checks:
• Visually check the cell electrodes. Only if necessary, remove the cell and flush
with a garden hose to remove any debris that may have passed through the
filter and lodged in the cell housing. Avoid inserting objects into the cell which
can scratch or bend the cell plates. Avoid wetting the power terminals.
• Check the free chlorine level.
• Check the total alkalinity. Adjust if necessary.
• Check the pH of the water. Adjust if necessary.
• Check the pressure gauge on the filter to see if backwashing is necessary.
• If no pressure gauge is present, see that returns to pool are running strongly.
Monthly checks:
• Check the salt concentration of the pool. Adjust if necessary.
• Check the chlorine stabilizer level. Adjust if necessary.
Regular checks:
• Clean the weir basket, pump strainer basket, cartridge filter and sand filter
(whichever is applicable)

Frequently asked questions
What is a Saline Blue Chlorinator?
• It is an automatic, electronic device that generates chlorine from salt (on-site-
electrolytic-chlorination)
• The SALINE BLUE salt water chlorinator consists of a cell, where the chlorine is
produced, and a power pack, which supplies regulated power to the cell.
How does a Saline Blue Chlorinator work?
• Chlorine is generated by pumping mildly salted water through the cell during
the normal filtration cycle which is returned to the swimming pool where the
chlorine gas acts to purify the water.
Why use a Saline Blue Salt Chlorinator?
• Salt chlorination is the healthy alternative to chlorinating your pool; the natural
way.
• No need for dangerous storing of granular or liquid chlorine.
• No more red eyes and dry itchy skin.
• Lower maintenance and lower operating costs compared to any other
chlorination method.
• Quick and easy to install.
What size model will I need?
• Small pools from as little as 10 000 liters can be accurately chlorinated by the
SBR50.
• The SBR-50 Chlorinator will handle up to 50.000 liter pools in cooler climates.
• The SBR-100 model will sanitize larger pools up to 100.000 liters.
• The SBR-150 Salt Chlorinator is manufactured for swimming pools up to
150.000 liters.
• Pools up to 1500 000L can be catered for by using multiples of the above
chlorinators.
How long will the cell last?
• Our electrode coatings are designed for 10 000 hour life spans under normal
operating conditions.
• Depending on operating conditions, expect to replace the cell every 3-6 years.
• 15 000 hour electrode material is available on request for even longer life
spans.
How do I get started?
• It's easy! After installing your salt chlorinator simply add the recommended
amount of salt to your swimming pool.
• Choose your desired filtration run cycles.
• Choose desired chlorine output.
How much salt will I need?
• SALINE BLUE salt water chlorinators are designed to operate at salt
concentrations 4 000 parts per million (.4%) and up.
• A salt level of 4 000 ppm - 6000ppm is optimum.
• Sea water, by way of comparison, is about 35 000ppm (3.5%).
What type of salt should I use?
• High purity salt is recommended.
• Iodated salt is NOT suitable.
• Consult your pool dealer for further advice.
Will I need to add salt later?
• Yes. The amount required depends on climatic conditions, frequency of
backwashing, splash-out, pool leaks and of course, pool volume.
• Salt is not lost via evaporation or during chlorinator operation.
• As a rough guide, you can expect to add between 25 - 50% of the initial amount
of salt added at start-up, annually.
What will happen if my salt level is too high?
• Nothing at all. SALINE BLUE salt chlorinators are overload and short circuit proof
and will not be damaged at any salt level.
• In fact, higher salt concentrations are beneficial as they increase the chlorine
output and life span of the cell.
How do I know when to add salt?
• It's easy! Simply check the status of the 'Salt Low'' indicator on the SALINE BLUE
power pack and top up with salt when the indicator is illuminated.
• Your pool dealer will be able to test your water and advice on precise levels if
desired.
Is there any maintenance involved?
• SALINE BLUE Salt Chlorinators use sealed, self-cleaning cells that remain scale
free during their operation, eliminating the need for manual scale removal.
• However good a SALINE BLUE Salt Chlorinator is, remember it was developed to
assist you with the maintenance of your swimming pool. The water chemistry
still needs to be within certain parameters for the chlorinator to be effective.
Does salt damage pool equipment?
• Modern pool equipment materials will not be damaged by the low levels of salt
used by SALINE BLUE salt chlorinators.
• However, should your swimming pool be more than 20 years old and have
visible steel piping and fittings, then these should be replaced with PVC or other
suitable plastic material.
