Problem Possible Cause
Corrective Action
Flow light is on (Display says “No Flow”).
Caused by insuffi cient water fl ow through
the cell.
NOTE When the Flow light is on,
the chlorine output will be
turned off.
The pump or skimmer
baskets are fi lled with debris
preventing suffi cient water
fl ow through the system.
Check and clean the pump and
skimmer baskets.
Dirty fi lter. Clean the fi lter.
Closed valves. Check and correct all valve
alignments.
Pump fails to provide
suffi cient water fl ow.
Check for correct operation of the
pump.
Make sure pump is sized properly for
required fl ow rate.
Problem Possible Cause Corrective Action
Salt light is on and the display says “Check
Salt or Low Temperature”.
NOTE The Salt light will turn on
when the salt level drops well
below 3,000 ppm and it will
remain on until the salt level is
raised above 4,000 ppm.
* If an AquaLink
®
RS or PDA is installed,
when the salt level is low, the AquaLink
RS or PDA will display, “Salt 2900 PPM,
Check AquaPure
®
, (Low Salt)”.
Salt level is well below 3,000
ppm, depending on water
temperature.
Maintain a salinity level of
4,000 ppm - 4,500 ppm
(see Section 4.6 or contact
your local pool professional).
Cell life expired. Replace the cell.
Problem Possible Cause Corrective Action
Display says “Check Salt or Low
Temperature” (Salt light is off).
A combination of low water
temperature (35°-65°F /
2°-18°C) and lower salt levels
(3,500 - 4,000 ppm).
Check salt level in pool water. If
level is between 4,000 - 4,500 ppm,
no action is necessary. If salt levels
are lower than 4,000 ppm, raise the
salinity level to 4,000 - 4,500 ppm
(see Section 4.6).
NOTE Salt levels above 6,000 ppm
may cause corrosion damage.
