Winterizing
11.7.1 Passive winterizing
In the event that pool filtration is completely stopped during the winter, proceed as follows to avoid any
damage that could be cause by freezing or clogging with algae:
Close the two shut-off valves on the by-pass loop on which the cell and acid dosing pump are mounted.
ACID DOSING PUMP:
•
Rinse the pump tubing as follows to remove any traces of acid:
•
Pull the suction tube and strainer carefully out of the acid buffer tank and immerse it into a bucket
of water.
•
run the pump either in pH Reducing - Manual mode if filtration is running, or in Cell Cleaning
Manual mode if filtration is stopped.
•
When at least half of the bucket has been emptied, stop the pump.
•
Disconnect the acid suction tube from the blue connector on the pump.
•
Remove the transparent splash guard.
•
Carefully disconnect the acid injection tube from the injection nipple and allow water from the pumping
circuit to empty into a bucket placed below.
CELL:
•
Descale and clean the cell (ref VIII.5), either using the acid dosing pump before it is winterized, or manually
after dismantling the cell (ref. X.5) ;
•
Open the bottom union to drain water from the cell, then screw the union shut ;
•
Unscrew the blue head of the flow sensor and remove it.
SENSORS:
•
Cut the power supply to the electrical/ control panel;
•
Disconnect the sensors from the electrical/ control panel;
•
Close the shut-off valve on the by-pass loop on which the sensors are mounted;
•
remove the sensors and place them in their phials of buffer solution and store them in an area protected
against freezing.
