Remove the sample cell from the control panel
Strip all removable components from the cell
Thoroughly check and clean the components, replace if required
Re assemble sample cell and refit to control panel
Insert new chlorine and Ph. monitoring probes
Turn sample cell water flow back on
Check cell pressure (adjust as required to 100mbar)
Ensure there is a good flow of water through the sample cell
And check that the flow switch deactivates chemical feeders when there is no
flow to the sample cell
Flow switch to be checked weekly
Check the menu settings on the control panel are adequate for the pool it is
running, BEFORE adjusting anything check with client this is acceptable to
them
This includes: set point, pump settings and
time out
Leave the controller to “settle” for as long as needed
