PROBLEM
TYPICAL SOLUTION
Cell inspect due
This is an advisory
message.
The unit will generate
chlorine normally
while this message is
displayed.
The cell has been operating for a while. This is a
reminder that now would be a good time to remove and
inspect the cell and filter screen to see if they need
cleaning. No problem has been detected. This is simply
a time elapsed maintenance message. Press and hold
SELECT to clear this message.
Cell is cleaning
This is an advisory
message.
The cell is reversing polarity when this message is
displayed. Normal production will resume shortly.
Purify Off
## Day(s)
Chlorine generation
is off and will start in
## days. This is an
advisory message.
The Purify Off feature has been activated. See section
7.6.10 for more information or to inactivate this feature.

Check flow
Chlorine generation
has stopped due to
insufficient water flow.
1. Turn on the circulation pump.
2. Turn the control valves to the correct position to
allow water flow through the manifold.
3. If installed, check suction type vacuum cleaner for
blocked or restricted water flow.
4. Check and clean the skimmer basket.
5. Check and clean the pump basket.
6. Check and clean or backwash the main circulation
filter.
7. Clean the manifold screen of trash or debris. For
instructions to clean the screen, test the flow switch,
clean the bypass valve (on a bypass manifold only),
see Maintenance section 6.2.4 “Test Tri-sensor
Flow Switch” on page 14 of the manual.
8. Verify that the Tri-sensor cable is plugged in. Plug it
in, using care to orient it correctly before inserting it.
See page 13.
9. Clean the cell if clogged with debris or calcium
scale. See section 6.3 on page 15.
10. Check for air in the bypass manifold by loosening
the top union on the cell to see if air or water comes
out. If air comes out then there may be a vacuum
side leak or the pump may be undersized. Check for
leak at pump basket O-ring, leaking valve or fitting.
11. If the pump is a 2-speed pump, is it on low speed?
The low speed may not create enough flow for the
manifold. If using a variable speed pump, increase
the RPM.

Add salt xxx lb
Chlorine generation
has stopped because
the salt level is below
2,000 ppm (mg/L)
(which is too low).
Add salt as indicated on the Digital Nano/Nano+ display
to bring the salt level up to 3,000 ppm (mg/L).
Warning!
Add salt xxx lb
The salt level is
between 2,000-2,400
ppm (mg/L) (which is
low).
Add salt as indicated on the Digital Nano/Nano+ display
to bring the salt level up to 3,000 ppm (mg/L).
Error purify off
Add salt xxx lb
Warning!
Add salt xxx lb
Added salt as
indicated by the
Digital Nano/Nano+,
but salt level still
shows low.
1. The pool volume has not been set up in the Installer
Menu and is higher than the factory default of
15,000 gallons (60,000 liters).
2. The salt sensor in the Tri-sensor may be dirty.
3. The Salt display may need to be calibrated. See
“Calibrate Salt” on page 23
