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 temperature 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 effec-
tively 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 Output %" setting
To find the optimum "Desired Output %" 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 com-
pensate 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 chlo-
rine 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.
Maintaining the Aqua Trol System
To maintain maximum performance, it is recommended that you open and visually
inspect the cell every 3 months or after cleaning your filter. The Aqua Trol will remind
you to do this by flashing the "Inspect Cell" LED after approximately 500 hours of
operation. After you inspect the cell (and clean, if necessary) press the small "diag-
nostic" button next to the display for 3 seconds to stop the flashing "Inspect Cell"
LED and start the timer for the next 500 hour inspection period.
The Aqua Trol electrolytic cell has a self cleaning feature incorporated into the elec-
tronic control’s logic. In most cases this self cleaning action will keep the cell working
at optimum efficiency. In areas where water is hard (high mineral content) and in pools
where the water chemistry has been allowed to get "out of balance", the cell may
require periodic cleaning. The "Inspect Cell" LED will indicate if cell efficiency is
decreased and servicing is necessary. If the "Inspect Cell" LED remains on after a
thorough cleaning, the cell may be worn and require replacement.

Controls
The pool filter pump should run long enough to circulate the entire volume of pool
water each day. This will vary depending on pump size, pool plumbing and pool size.
Consult a local pool store to help determine the appropriate run time for your pool.
Main Switch
AUTO
: For normal operation, the Main Switch should be left in the AUTO posi-
tion. In this position the Aqua Trol will produce chlorine according to the "De-
sired Output %" adjustment setting for the entire filtering/pumping cycle.
SUPER CHLORINATE
: When you have an abnormally high bather load, a large
amount of rain, a cloudy water condition, or any other condition which needs a
large amount of purification to be introduced, put the Main Switch in the SUPER
CHLORINATE position. This electronically “super chlorinates” (shocks) the wa-
ter for 24 hours (filter pump must be on during this time) or until the power has
been turned off, whichever comes first. At the end of the super chlorinate time, be
sure to put the switch back into the AUTO position.
OFF
: The OFF position prevents the Aqua Trol from energizing the electrolytic
cell. In this position there is no chlorine generation. NOTE: To service any of the
pool equipment or the Aqua Trol, turn the power off at the circuit breaker.
Desired Output % adjustment knob
This setting is used to control the amount of chlorine the Aqua Trol generates. Raise
this setting to increase chlorine level and lower it to decrease chlorine level.
Indicator LED's
POWER
When illuminated, the Aqua Trol has input power.
GENERATING
This LED is on steady during normal operation. When flashing,
the pool water is too hot or cold to operate.
SUPER CHLORINATE
Illuminates during Super Chlorination. See description
above.
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.
