Water Chemistry - Hayward AquaRite + Owner's Manual

Preparing the Pool Water
The pool's water chemistry must be balanced BEFORE activating the AquaRite+. Adjustments to the chemical balance of the pool can take
several hours, so the "water balancing" procedure must therefore be started well before the AquaRite+ is turned on.
Adding salt: Add the salt several hours or, if possible, a day before turning on the AquaRite+. Ensure that the recommended amount of salt
is used, as described below and on page 12. 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 water, add a metal remover and a non-copper based algaecide to the pool, following the manufacturer's
instructions. If your water has previously been treated with a product other than chlorine (bromine, hydrogen peroxide, PHMB, etc.), neutralise 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 concentration. Use the formulae below if
you do not know the volume of your swimming pool.
IMPORTANT: The ideal salt concentration is between 2.7 and 3.4 g/L, with 3.2 g/L being optimal.
Before adding any salt, test the salt level. This is especially important for retrofit installations to older pools where all of the chlorine added
to the pool over time is ending up as salt. If the level is low, determine the number of litres in the pool and add salt according to the table on
page 12. A low salt level will reduce the efficiency of the electrolysis and result in low chlorine production. A high salt level can cause the
AquaRite+ to stop chlorinating or prematurely ware out componentry. The salt in your pool/spa is constantly recycled and the loss of salt
throughout the swimming season should be minimal. This loss is due primarily to the addition of water because of splashing, back-washing, or
draining (because of rain). Salt is not lost due to evaporation.
Type of Salt to Use
Use only salt intended for chlorinators and only that of which is 99% pure sodium chloride (NaCl). This can be found at most pool stores in
20 - 25 kg bags labeled "for use in swimming pools". Alternatively, use common food quality or water softener salt that is at least 99.0%
pure. It is also acceptable to use water conditioning salt pellets, however, it will take longer for them to dissolve. Do not use rock salt, iodized
salt, salt containing more than 1% yellow prussiate of soda or salt containing anti-caking additives.
How to Add or Remove Salt
For new plaster pools, wait 10 -14 days before adding salt to allow the plaster to cure. Turn the circulating pump on and add salt directly into
the pool. Brush the salt around to speed up the dissolving process - do not allow salt to pile up on the bottom of the pool. Run the filter pump
for 24 hours with the suction coming from the main drain (use pool vacuum if there is no main drain) to allow the salt to evenly disperse
throughout the pool. The salt display may take 24 hours to respond to the change in salt concentration.
Always check stabiliser (cyanuric acid), when checking salt. These levels will most likely decline together. Use the chart on page 12 to
determine how much stabiliser must be added to raise the level to 30 ppm. Start with a stabliser level of 30 ppm and only increase it if
there are issues with maintaining the desired free chlorine level.
To remove salt, drain the pool down and replenish with fresh water. Repeat until the desired level is achieved.
Do not add stabiliser to indoor pools.
