SERVICING
During the first 10-15 days, your system will require more attention:
- Check that the pH remains at the ideal level (7.2 to 7.4).
- If the pH is exceptionally unstable and uses a lot of acid, check the alkalinity (see table).
If the balance is highly unstable, contact your pool installer/builder.
REMEMBER that the system needs a certain amount of time to adapt to your pool and will require additional chemicals during the
first 3-5 days.
The pool must be regularly maintained and the skimmer baskets emptied whenever necessary.
Also check that your filter is not clogged.
ADD WATER: It is preferable to add water via the skimmers so that it passes through the cell before entering the pool. Remember to
check the salt percentage after adding water.
DOSING PUMPS: Regularly check the acid level to ensure that the pump does not run dry. The dosing pump must be checked and
serviced at regular intervals.
Servicing the probe
The probe must be clean and free from oil, chemical deposits and contamination to function properly. As it is in continuous contact with
the water in the pool, the probe may need to be cleaned weekly or monthly, depending on the number of bathers and other specific pool
characteristics. A slow response, more frequent pH calibration and inconsistent readings indicate that the probe need to be cleaned.
To clean the probe, turn off the power to the AquaRite LT.
Unplug the probe connector from the control box, unscrew the probe and carefully remove it from the chamber. Clean the probe bulb
with a soft toothbrush and regular toothpaste.
A household washing-up liquid detergent may also be used to remove any oil.
Rinse with fresh water, replace the Teflon tape on the threads, and reinstall the probe.
If the probe continues to give inconsistent readings or requires excessive calibration after it has been cleaned, it should be replaced.
Servicing and cleaning the AquaRite LT cell
Turn off the main power supply to the AquaRite LT 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 AquaRite LT. 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 submerg-
ing 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 AquaRite LT cell, the flow switch, probe 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 probe must always be in contact with water or a solution of KCl. If it is removed from the measuring chamber, it should
be stored in the plastic cap provided (filled with water). If the storage cap has been mislaid, the probe should be stored separately in a
small glass or plastic container with its end immersed in water.
The probe must always be in a frost-free environment.
