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.

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.
