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 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 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 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 "diagnostic" 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
electronic 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 re-
quire replacement.
Servicing and Cleaning the Aqua Trol cell
Turn off power to the Aqua Trol before removing the electrolytic cell. Once
removed, look inside the cell and inspect for scale formation (light colored crusty
or flaky deposits) on the plates and for any debris which has passed through the
filter and caught on the plates. If no deposits are visible, reinstall. If deposits are
seen, use a high pressure garden hose and try to flush the scale off. If this is not
successful, use a plastic or wood tool (do not use metal as this will scratch the
coating off the plates) and scrape deposits off of the plates. Note that a buildup
on the cell indicates that there is an unusually high calcium level in the pool (old
pool water is usually the cause). If this is not corrected, you can expect to have to
periodically clean the cell. The simplest way to avoid this is to bring the pool
chemistry to the recommended levels as specified.
Mild Acid Washing:
Use only in severe cases where flushing and scraping will
not remove the majority of deposits. To acid wash, turn off power to Aqua Trol.
Remove cell from piping. In a clean plastic container, mix a 4:1 solution of water
to muriatic acid (one gallon of water to one quart of muriatic acid). ALWAYS
POUR ACID INTO WATER - NEVER POUR WATER INTO ACID. Be sure to
wear rubber gloves and appropriate eye protection. The level of the solution in
the container should just reach the top of the cell so that the wire harness com-
partment is NOT submerged. It may be helpful to coil the wiring before immers-
ing the cell. The cell should soak for a few minutes and then rinse with a high
pressure garden hose. If any deposits are still visible, repeat soaking and rinsing.
Replace cell and inspect again periodically.
Winterizing
The Aqua Trol electrolytic cell and flow detection switch will be damaged by
freezing water just as your pool plumbing would. In areas of the country which
experience severe or extended periods of freezing temperatures, be sure to drain
all water from the pump, filter, and supply and return lines before any freezing
conditions occur. The electronic control is capable of withstanding any winter
weather and should not be removed.
Spring Start-up
DO NOT turn the Aqua Trol on, until the pool water chemistry has been brought
to the proper levels. This information can be found on page 2.
