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.
DOSING PUMPS: Check the levels regularly to ensure that the pumps do not run on empty. The dosing pumps must be
checked and serviced at regular intervals.
Servicing the probes
The probes must be clean and free from oil, chemical deposits and contamination to function properly. As they are in
continuous contact with the water in the pool, the probes 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 probes need to be cleaned.
To clean the probes, turn off the power to the Control Station.
Unplug the probe connectors from the control box, unscrew the probes and carefully remove them from the chamber.
Clean the probe bulb (white ring at the bottom of the body of the probe) 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 probes.
If the probes continue to give inconsistent readings or require excessive calibration after they have been cleaned, they
should be replaced.
Wintering
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.
