MAINTENANCE
IMPORTANT
Close plunger valves on your pool or insert black hat-like plugs in strainer opening
to prevent water spillage. Open plunger valves or remove plugs when maintenance is
completed.
1
. In a counter-clockwise motion unscrew the collar of the flow sensor
(11)
and remove it from
the flow sensor conduit. See “Part Reference”.
2
. If deposits and debris are seen on the surface of the flow sensor, then use a garden hose to
wash it off.
3
. If flushing with water does not remove the deposits, use a plastic brush to clean the surface
and the hinge if necessary. Do not use a metal brush.
4
. After the flow sensor has been inspected and cleaned, align the locator notch on the flow
sensor to the connection ridge in the conduit. Now turn the collar in a clockwise motion,
tightening the sensor back into its position. Do not overtighten.
The electrodes have a self cleaning function incorporated into the electronic control’s
programming. In most cases this self cleaning action will keep the electrodes working at optimum
efficiency. If the pool water is hard (high mineral content) the electrodes may require periodic
manual cleaning. To maintain maximum performance, we recommend that you open and visually
inspect the primary and secondary electrodes
(31 & 14)
monthly.
The following steps provide instructions on how to clean your cell.
