PROBLEM
Salt level on display
does not match pool
store or salt test strip.
Conductivity of the
water is reduced;
usually caused by low
salt, cold water or a
scaled cell or a
combination thereof.
The salt level is below
2800 ppm (mg/L) &
temperature below
70°F (21°C).
The salt display
differs from salt test.
The cell is scaled.
If this is a new
installation...
Cell is completely
clogged from calcium
scale, has failed, or
the cell cord is loose
or damaged.
The cell cord is
disconnected
The cell is heavily
scaled.
If this is a new
installation...
TYPICAL SOLUTION

The test may have been faulty or the salt strips may
be old or damaged. Have salt level rechecked at
local pool store.

If the discrepancy is more than 400 (mg/L), then
calibrate salt. See "Calibrating Salt" on page19 for
more information.

Check the salt level and adjust to 3000 ppm (mg/L)
or verify salt calibration.

For water temperatures below 65°F (18.3°C),
increase salt to 3500 ppm (mg/L).

Remove and inspect the cell for white calcium scale.
(See cell inspection and cleaning instructions in the
Maintenance section of manual.)
Increase salt level to 3500 ppm (mg/L) or increase
temperature on heater if applicable.
Adjust salt display in the Salt Calibration mode. (See
Calibrating Salt, in the Programming section of manual.)
Determine frequency of scaling.

ONE week or less = Power Supply not reversing
polarity – contact factory.

TWO weeks or more = Water Chemistry related
problem (See Reference section of manual, Water
Chemistry and Saturation Index topics).
Adjust water chemistry or adjust "Set Reverse" to a
shorter cycle.
Verify the incoming voltage matches the voltage of the
Digital Nano/Nano + . (See Specifications and Installation
sections of manual.)

Check cell for calcium scale buildup. Clean as
needed.

Check for visual wear on the edges of the terminal
blades which may be an indication that cell is
depleted.

Check the cell cord for tight connections on the cell
and on the power supply. Check the plug for burns.
Tighten or replace as needed.

Replace cell if depleted.
Verify cell cables are inserted fully into the Digital
Nano/Nano + base cell connector.
Remove and acid wash as described in Maintenance
section of manual.
Verify that the incoming voltage matches the voltage of
the Digital Nano/Nano + . (See Specifications and
Installation sections of manual.)
