NO FLOW When illuminated, the flow switch has detected no flow and the Aqua Trol
®
has stopped
generating chlorine. A flashing LED indicates a 15/60 second time delay period.
TEST SALT LEVEL When flashing, the salt level is low (below 2700ppm) and Aqua Trol is generating
at low efficiency. When illuminated steady, the salt level is too low and Aqua Trol has shut down.
Before adding large quantities of salt, it is advisable to have your salt level professionally checked.
HIGH SALT When illuminated, the salt level is too high and Aqua Trol has shut down.
INSPECT CELL A flashing indicator signifies that either the cell efficiency is reduced or that it is
time for regularly scheduled cell inspection. In either case, inspect the cell and clean if necessary.
Pressing the “diagnostic” button next to the display for 3 seconds will stop the flashing LED. When
illuminated steady, cell efficiency is greatly reduced and the Aqua Trol has stopped producing chlo-
rine. Inspect, clean or replace if necessary.
Salt Display
The Salt Display shows the current salt concentration of the pool water. Readings are in ppm (parts
per million). Refer to the Water Chemistry section for recommended salt levels as well as how to
add/remove salt.
The factory default display is in English (ppm). If Metric units (grams per liter) are preferred, push
the “diagnostic” button next to the display once. The display will now show the pool water tempera-
ture in degrees Fahrenheit. With the temperature displayed, move the main switch from AUTO to
SUPER CHLORINATE to AUTO. The temperature display will instantly change to degrees Celsius and
the salt display will switch to grams/liter. Repeat this process to switch back to English units (ppm
and Fahrenheit).
Operation
By understanding how the Aqua Trol operates, you’ll be sure to use it more effectively for maximum
convenience and performance. Assuming that the water chemical levels are in the recommended
range, there are three factors that you can control which directly contribute to the amount of chlorine
the Aqua Trol will generate:
1. filter time each day (hours)
2. the amount of salt in the pool
3. the “Desired Level %” setting
To find the optimum “Desired Level %” setting, start at a fairly high setting and work downward. It
will take a few days of adjustments to find the ideal setting for your pool/spa. Once determined, it
should only take minor adjustments, if at all, to compensate for differing salt levels due to splashing,
backwashing, rain, etc. Because the production of chlorine is affected by water temperature, it is
important to check chlorine levels during periods of unusually high or low pool water temperatures.
The Aqua Trol control will not produce chlorine at temperatures below 50º F. If your pool will be
below this temperature for any length of time, you must chlorinate manually.
NOTE: After the ideal “Desired Output %” setting has been found, you may need to raise the setting
when the pool water temperature increases significantly, when there is higher than normal bather
load or when your chlorinator cell ages. You may need to lower the setting when the pool water
temperature decreases significantly or there are long periods of inactivity.
