6.4 Flow/Temp/Salinity Sensor Cleaning
One time per year or as needed. It is rare but scale formations on the ow/temp/salinity sensor sometimes
occur and will affect the accuracy of the salinity test.
1. Remove ow/temp/salinity sensor from the 3-port cell.
2. Brush with a mildly abrasive green ber household cleaning pad. Contacts should be clean and bright.
3. Thoroughly rinse the ow/temp/salinity sensor with clean tap water. Replace and resume normal
operation.
4. Turn power off and back on in order to recalibrate and reset Flow/Temp/Salinity Sensor. Reset
anytime Flow/Temp/Salinity Sensor is unplugged.
6.5 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 ow/
temp/salinity sensor. Prevent freeze damage to the cell and ow/temp/salinity sensor by running pump
continuously or winterize pool by draining water from pump, lter, and all intake and return lines. Remove
the cell, clean and store it. Disconnect the ow/temp/salinity sensor from the power center, then remove it
from the 3-port cell. Wrap ow/temp/salinity sensor in a plastic bag or protective covering and coil 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 cell during winterizing or cell
maintenance. This will enable pool pump to circulate water with the cell out the of line. See Figure 19.
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 - 3 ppm.
NOTE A chlorine level above 3 ppm may cause corrosion of pool metals and possibly cause damage to associated
pool equipment.
