Winterizing

Very little chlorine is needed in cold water. Below
51°F (11°C), operating the chlorinator in cold water
might result in over-chlorinated pool water.
If preventative measures are not taken, freezing
water may cause severe damage to the cell and
flow/ temp/salinity sensor. Prevent freeze damage
to the cell and flow/temp/salinity sensor by running
pump continuously or winterize pool by draining
water from pump, filter, and all intake and return
lines. Remove the cell, clean and store it.
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.
