Aq
Rev. B
Preparing the pool water
To prepare the pool water to enable the Aq to function, its chemical composition must be balanced and salt added. This
must be done
BEFORE
turning on the Aq. Certain adjustments to the chemical balance of the pool can take several hours.
The procedure must therefore be started well before the Aq is turned on.
Adding salt: Add the salt several hours or, if possible, a day before turning on the Aq. Ensure that the recommended
amount of salt is used. Measure the salt content 6 to 8 hours after adding the salt to the swimming pool.
NOTE:
If the water in the pool is not fresh and/or if it is liable to contain dissolved metals, use a metal remover, according to the
manufacturer's instructions.
If your water has previously been treated with a product other than chlorine (bromine, hydrogen peroxide, PHMB, etc.), neutralize
this product or replace all the water in the pool.
Salt concentration
Use the following table to determine the quantity of salt (in kg) needed to reach the recommended concentrations. Use the
formulae below if you do not know the volume of your swimming pool.

The ideal salt concentration is between 2.7 and 3.4 g/l, with 3.2 g/l being the optimum value. If the level is low, determine
the volume (m3) of the pool and add salt in accordance with the following table. A low salt level reduces the efficiency of the
Aq and reduces chlorine production. A high salt concentration can cause the Aq to fail and make your pool
water taste salty. As the salt in your pool is constantly being recycled, the loss of salt during the season is minimal. Salt is
mainly lost when water has to be added due to splashing, backwashing or draining (because of rain). Salt is not lost through
evaporation.
Type of salt to use
Use only salt intended for chlorinators in conformance with EN 16401. Use only sodium chloride (NaCl) that is more than 99%
pure. Do not use food-grade salt, iodized salt, salt containing yellow prussiate of soda or salt containing anti-caking additives.
How to add or remove salt
For new pools, let the plaster cure for ten to fourteen days before adding salt. Start up the filtration pump, then add salt
directly into the discharge side of the pool. Make the water circulate to speed up the dissolution process. Do not allow salt to
accumulate at the bottom of the pool. Run the filtration pump for 24 hours, opening the main drain valve fully to allow the salt to
dissolve evenly throughout the pool.
The only way to lower the salt concentration is to partially empty the pool and refill it with fresh water.
Always check the stabilizer (cyanuric acid) when checking the salt concentration. The corresponding concentrations tend to
decrease together. Refer to the following table to determine the quantity of stabilizer to be added to bring the concentration to
25 ppm. Add stabilizer only if necessary.
Do not add stabilizer to indoor pools.
