Problem
Possible Cause
Corrective Action
Temporary loss of chlorine due to heavy
organic load - rain, leaves, fertilizer or
heavy bather load. Pets using pool.
Set chlorine production to 100% and set
the pump and the cell to run for 24 hours.
After 24 hours, recheck chlorine levels. If
still too low, super chlorinate with alternate
source to achieve Breakpoint Chlorination
(BPC). Your local pool dealer can assist
with this if you take to them a sample of
your water.
Low (less than 3,000 ppm) salt level in
pool water.
Use salinity test strips, a TDS/salinity
meter, or another reliable method to test
the salinity of the pool water. Once the
existing salinity has been established, use
Table 1 to determine the amount of salt to
add to reach the desired level. Maintain a
salinity level of 3,000 ppm.
High nitrate level.
Contact a pool professional.
Metals present in pool water.
Contact a pool professional.
New pool water. Not shocked properly
upon startup.
Super chlorinate the pool.
Clogged or dirty cell.
Remove cell for inspection and clean if
necessary (see Section 6.3).
Chlorine level too high.
(above 7.0 PPM)
Chlorine output percentage set too high.
Decrease chlorine production rate by
pressing the Output button (see Section 6.3)
Power pack and cell turned on too long.
If chlorine output is set at the lowest setting
and it consistently provides excessive
chlorine levels, decrease operation time as
much as necessary.
No display on LCD
(screen is blank).
No power to unit.
Check the connection to the pump timer.
Check if GFCI tripped.
Display says “No
Flow”. Caused by
insufficient water flow
through the cell.
Caused by insufficient water flow through
the cell.
NOTE
When the Flow light is on, the chlorine
output will be turned off.
Check and clean the pump and skimmer
baskets.
Dirty filter.
Clean the filter.
Poor connection between cell and power
Check for secure connection to power pack
pack
Closed valves.
Check and correct all valve alignments.
Pump fails to provide sufficient water
flow.
Check for correct operation of the pump.
Make sure pump is sized properly for
required flow rate.
The display says “Check
Salt”.
Salt level is well below 2,500 ppm,
depending on water temperature.
Maintain a salinity level of 3,000 ppm -
3,500 ppm (see Section 5.6 or contact your
local pool professional).
Calcium buildup in the cell
Clean the Cell
