Winterizing

Very little chlorine is needed in cold water. Below 51°F (11°C), chlorine production is not permitted; operating the
chlorinator in cold water might result in over-chlorinated pool water. If more chlorine is needed, activating the
"Boost" mode will override this cold water feature allowing chlorine production for 24 hours of operation. See
Section 5.1, User Interface Controls.
If preventative measures are not taken, freezing water may cause severe damage to the cell and fl ow/temp/salinity
sensor. Prevent freeze damage to the cell and fl ow/temp/salinity sensor by running pump continuously or winterize
pool by draining water from pump, fi lter, and all intake and return lines. Remove the cell, clean and store it.
Disconnect the fl ow/temp/salinity sensor from the power center, then remove it from the vessel. Wrap fl ow/temp/
salinity sensor in a plastic bag or protective covering and coil fl ow/temp/salinity sensor and DC power cord cables
around the power center for storage.
An optional Spool Piece (sold separately) is available to replace the vessel during winterizing or vessel maintenance.
This will enable pool pump to circulate water with the vessel out the of line.
When a FREEZE CONTROLLER is used on pump equipment and the chlorinator is run through the winter, turn the
CHLORINE PRODUCTION down to 10 - 20%. Otherwise, chlorine production will exceed the recommended level
of 1.0 - 3.0 ppm.
NOTE A chlorine level above 3.0 ppm may cause corrosion of pool metals and possibly cause damage to associated
pool equipment.
