WATER BALANCE
The balance of your pool water is no less critical because you have installed a
salt chlorinator.
All three components, pH, Total Alkalinity and the Calcium hardness are like a
three legged stool, take one leg away or cut it too short and the stool falls over.
The analogy simply emphasizes that all three must be maintained within the
recommended parameters suggested for your pool finish.
pH
A high pH will reduce the effectiveness of chlorine, potentially cause scale on
both the pool and the equipment, and irritate bathers.
A low pH may cause the water to become corrosive, damaging the pool interior
finish, equipment (heat exchangers especially) and also irritate bathers.
Each pool finish and type has a specific range in which the pH should remain.
Generally a pH of between 7.2 - 7.8 is suitable for most pool types, however
those requiring a higher pH will also require a higher chlorine residual. (Consult
with your pool professional)
Total alkalinity (T.A.)
The total alkalinity is a measurement of all the alkalis in your pool water, (Carbon-
ates, Bicarbonates and Hydroxides).
When adjusted within the accepted levels, T.A. acts as a pH buffer, resisting
change to the pH. The recommended T.A. level of your pool may vary from 40
ppm - 180 ppm depending on the pool finish, again consult with a pool water
professional. We recommend levels around 80 ppm.
Calcium Hardness
Probably the most ignored of the three yet just as important.
The hardness of your pool water is very important in controlling scale and the
corrosive, effects of water. A low calcium level may cause pool water to become
corrosive even if the pH is within its recommended range. A tell tale sign of this
is brown stains on the pool finish and in adjoining Spa’s especially. This is metal
staining, the source is usually the heater. A high calcium level may cause pool
water to deposit scale, again even if the pH is within its recommended range.
Standard salt chlorinator cell will require very frequent cleaning and scale may
deposit on pool finish and equipment. Generally a level of 50ppm - 200ppm is
recommended. Consult with your pool builder or pool store.
Note: We strongly recommend you seek advice from a pool professional
regarding the balancing of water for your pool. A correctly balanced pool
will protect It and the equipment from chemical damage and ensure bathers
are swimming In clean clear healthy pool water.

CYANURIC ACID - CHLORINE STABILIZER
The sun’s ultraviolet light breaks down chlorine, with this in mind, it is essential in
sunny climates to use a chlorine stabilizer.
The importance of it’s use is such that our range of chlorinators are sized with the
express requirement that chlorine stabilizer be used as per the directions.
Cyanuric acid or chlorine stabilizer, when dissolved in the pool water to achieve
levels of between 50 ppm to 80 ppm will effectively reduce the breakdown of
chlorine by ultraviolet light.
Higher stabilizer levels may in fact be detrimental and hinder the kill rate of
chlorine. Consult with your pool professional.
Maintaining a correct stabilizer level will benefit the cell in an indirect way. The
operating output percentage required would be lower than with an unstabilized
pool. This factor extends cell life.
TROUBLESHOOTING
Display is not illuminated
Possible cause:
Chlorinator power supply is not wired to 110v or 220v source.
Solution:
Wire into 110v or 220v source.
Possible cause:
Chlorinator is switched off via an external time clock.
Solution:
No action necessary. Perhaps momentarily override time clock
to check units operation.
Possible cause:
Chlorinator is wired into a special tariff power supply that
switches the power supply off for a period every day.
Solution:
Wait until power is restored to check chlorinator.
Flow Fail - OFF scrolls across the display and pump has switched off
Possible cause:
The pump protection monitor has been set and has timed out.
Solution:
Investigate flow problem by eliminating possible solutions from
the Lo Flow - OFF section on next page. (To reset, push the
mode button)
Note:
Remember, any filter settings that require the pump to run and
where the water is not returned through the cell, eg. back-wash-
ing, rinse, waste etc. will cause the pump protection monitor to
activate if the period exceeds the programmed time out period.
Note: If the cell Is disconnected for any reason, always remember to
disable the pump protection monitor (set to zero) or the pump will continue
to switch off after the time out period.
