* Fill pool with water from the mains water supply. Do not use rain water or well water.
** Do not add salt directly into the skimmer. Do not initiate electrolysis until salt has fully dissolved.

6.2 pH Regulation Principle
The amount of chlorine needing to be produced is dictated by the pH level in the pool. As the pH level
rises, the amount of chlorine must be increased to compensate, see Figure 11.
6.3 Chlorine Output and Filtration Time
Your eQ Chlorinator must be run every day to
ensure that your pool is correctly sanitised. As the
sun dissipates chlorine, running times are higher
in the summer compared to the winter. AstralPool
recommend that you initially run your chlorinator at
maximum output on level 8.
6.3.1 Summer
Set the eQ Chlorinator to operate for 8 to 10 hours
per day. Ideally, run it for 4-5 hours in the morning
(between 8-12pm) and 4-5 hours in the evening
(between 6.00-11pm).
In extremely hot weather it may be necessary to
extend the running time if you find that the free
chlorine level is too low.
6.3.2 Winter
You should set your eQ Chlorinator to operate for
6 to 8 hours per day. Again, running it in the
morning and evening is preferable. A lower chlorine
output level may be selected.
6.4 Water Chemistry
6.4.1 Chlorine Level
Ideally, check the Chlorine level after the morning
operating period. The free chlorine residual level
should be somewhere between 1 and 3 parts per
million. Increase or decrease the output of the
Chlorinator to get the right residual chlorine level.
It may also be necessary to adjust the operating
period if you are running at minimum or maximum
output.
6.4.2 Stabilizer (Cyanuric Acid)
Stabiliser (also referred to as sunscreen or cyanuric
acid) is not recommended to be used by Astralpool
with an eQ chlorinator and Chlorine probe fitted.
If Dichlor or Trichlor is used to supplement the
chlorine production of the eQ chlorinator or
Cyanuric Acid is added to the pool, the set point of
the chlorine (ORP) should be turned down.
Cyanuric Acid (CyA) is often recommended by or
added to swimming pools to make the available
chlorine last longer. It is often called stabiliser or
sunscreen. CyA bonds with chlorine ions which
prevents the chlorine from oxidizing bacteria
and other contaminants. This effectively reduces
the oxidization reduction potential (ORP) of the
