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 (measure-
ments 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 swim-
ming 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/
Goldline dealer. It is also acceptable to use water conditioning salt pellets, how-
ever, 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.

Bonding
A lug used for bonding is attached to the bottom of the Aqua Trol enclosure.
Connect to the pool bonding system using minimum 8AWG copper wire if required
by code.
Pump Output
The Aqua Trol's filter pump output is rated at 120 VAC, 15 A max. Check the
electrical rating marked on the pump motor. Connecting a pump with a higher
amperage rating may result in permanent damage to the Aqua Trol. The 120 VAC
standard or twist lock pump receptacle is located outside, on the bottom of the
enclosure.
Electrolytic Cell and Flow Switch
The cell and flow switch plug into connectors on the Aqua Trol electronics unit.
Note that return jet units (-RJ option) will NOT have a flow switch. See diagram
below.
