Salt Level
Use the chart on page 4 to determine how much salt in pounds (or Kgs) needs to be
added to reach the recommended levels. Use the equations below (measurements are
in feet/gallons and meters/liters) if pool size is unknown.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being
optimal. If the level is low, determine the number of gallons in the pool and add salt
according to the chart on page 4. A low salt level will reduce the efficiency of the Aqua
Trol and result in low chlorine production. A high salt level can cause the Aqua Trol
to shutdown and may begin to give a salty taste to your pool (generally, the salt will
begin to be tasted at a level of about 3500-4000 ppm). The salt in your pool is
constantly recycled and the loss of salt throughout the swimming season should be
small. This loss is due primarily to the addition of water because of splashing,
backwashing or draining (because of rain). Salt is not lost due to evaporation.
Type of Salt to Use
It is important to use only sodium chloride (NaCl) that is 99% pure. This is common
food quality or water softener salt available in 40-80 lb. bags at your local Hayward
dealer. It is also acceptable to use water conditioning salt pellets, however, it will take
longer for them to dissolve. Do not use rock salt, salt with more than 1% yellow
prussiate of soda, salt with more than 1% of anti-caking additives, or iodized salt.
How to Add or Remove Salt
Turn the filter pump on and add the salt directly into the pool. Brush the salt to speed
up the dissolving process--to not allow the salt to sit in a pile on the bottom of the
pool. Run the filter pump for 24 hours with the suction coming from the main drain
(use the pool vacuum if there is not 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.
The only way to lower the salt concentration is to partially drain the pool and refill
with fresh water.
Stabilizer (Cyanuric Acid
)
Always check stabilizer (cyanuric acid), when checking salt. These levels will most
likely decline together.

Preparing Pool Water
Refer to page 2 for recommended chemical levels. The pool's chemistry must be
balanced BEFORE activating the Aqua Trol. NOTE: If the pool does not have new
water, add 1 quart (1 liter) of metal remover and 1 quart (1 liter) of non-copper based
algaecide to the pool, per manufacturers instructions. This ensures a quick, troublefree
transfer to the Aqua Trol system.
Mounting the Aqua Trol Control
The Aqua Trol is contained in a raintight enclosure that is suitable for outdoor mount-
ing. The control must be mounted a minimum of 5 ft. (2 meters) horizontal distance (or
more if local codes require) from the pool.
The control is designed to mount vertically on a flat surface. Because the enclosure
also acts as a heat sink (disperses heat from inside the box), it is important not to
block the four sides of the control. Do not mount the Aqua Trol in a panel or tight
enclosed area.
