Servicing and cleaning the Aq cell
Turn off the main power supply to the Aq before removing the cell. Once it has been removed, examine the inside
of the cell for any traces of scale (whitish brittle or flaky deposits) and debris stuck to the plates. If no deposits are visible,
reinstall the cell. If deposits are visible, try to remove them with a garden hose. If this method is unsuccessful, use a plastic
or wooden tool to remove deposits stuck to plates (do not use a metal tool as this will damage their coating). A build-up of
deposits on the cell indicates an exceptionally high concentration of calcium in the pool water. If you cannot find a solution to
this situation, you will have to clean the cell at regular intervals. The best way to avoid this problem is to maintain the chemical
composition of the water at the recommended concentrations.
Acid washing: This should only be done in severe cases where flushing will not remove most of the deposits. To acid wash,
turn off the main power supply to the Aq. Remove the cell from the piping. In a clean plastic container, make up a
solution of water and acetic or phosphoric acid (such as that used to remove scale from a coffee machine).
ALWAYS ADD
ACID TO WATER - NEVER ADD WATER TO ACID
. Be sure to wear rubber gloves and protective goggles for this operation.
The level of the solution in the container should just reach the top of the cell, so that the wire harness compartment
IS NOT
under water. It may be helpful to coil up the wire before submerging the cell. Allow the cell to soak for a few minutes, then rinse
it with a garden hose. If the deposits are still visible, soak and rinse again. Put the cell back and examine it from time to time.
Wintering
The Aq cell, the flow switch, probes and pool piping run the risk of being damaged if the water freezes. In regions
that experience long periods of cold weather, be sure to drain all the water from the pump and filter and from the supply and
return pipes before winter. Do not remove the control unit.
Probe storage
The end of the probes must always be in contact with water or a solution of KCl. If they are removed from the measuring
chamber, they should be stored in the plastic caps provided (filled with water). If the storage caps have been mislaid, the
probes should be stored separately in small glass or plastic containers with their ends immersed in water.
The probes must always be in a frost-free environment.
TROUBLESHOOTING GUIDE
No display
Check that the On / Off switch is on.
Check the connection cable between the display and the control box.
Check that the external 250 mA fuse is not defective.
Check the power supply: 210-230 V
50 Hz.
If the problem persists, contact your pool installer/builder.
Excessive chlorine
Low electrolytic cell current.
If your pool has an automatic redox control system, check the redox setting.
Check the redox probe and calibrate, if necessary.
Electrolysis does not reach maximum intensity
Check the concentration of salt in the water.
Check the condition of the cell (it may be dirty or covered in scale).
Clean the cell according to instructions.
Check the flow switch and clean if necessary.
Check that the cell is not worn (contact your pool installer/builder).
Cell scaled up in under a month
Very hard water with high pH and total alkalinity (balance and adjust the pH and total alkalinity of the water).
Check that the system automatically changes polarity (see display)
