Low or no chlorine
residual in pool
Insufficient Chlorine
Output Level
Increase Output Level. This is
often required seasonally with
increasing temperatures.
Increase run time to at least 1
hour per 10° ambient temp.
Heavy pool use, inclement
weather, organic matter
Activate Super CL mode or
chemically shock pool.
Water chemistry issues:
Low Chlorine Stabilizer
Low salt in pool
Phosphates in pool
Nitrates in pool
Contact pool professional,
ensure all chemicals on p.6
are within range.
Cell is dirty, clogged, or
Has excessive scaling or
mineral build-up
Remove Cell from plumbing,
inspect and clean (see p.13).
Low or no Chlorine
residual in pool after
recent installation
Water chemistry was not
balanced prior to system
installation and a high
chlorine demand persists
Contact pool professional,
ensure all chemicals on p.6
are within range, chemically
shock pool if necessary.
System is connected to
incorrect voltage and is
not operational
Have a professional test
power source and ensure
correct connection.
Cell Maint. LED is on
(Has priority over salinity
LED indicators if also lit.)
It is time to clean
the Electrolytic Cell.
The Cell must be cleaned (see
page 13), or if flashing hold
Status button for 5 seconds.
Cell efficiency has been
greatly reduced
Inadequate water flow exists,
or Cell must be replaced.
Incorrect Cell Version set
Verify Cell Version in Status Menu.
Verify salinity (see page 3).
Check fuses on Control Module
Problem with input power,
voltage, or configuration of
system wiring
Have a professional test input
power & ensure correct wiring
configuration & connections.
