Problem 

Typical Solution 

Error! Purifier off 
Error! Acid off 
Check flow at sensors 

Flow at sensors is not detected.  Chlorine and acid 
are not fed under these conditions, until corrected. 

Ensure sufficient flow to the flow cell, pg. 44. 
Open the inlet and outlet valves to the flow cell.  
Valve handles should be vertical. 
Verify that the sample water valve is closed, 
valve handle horizontal. 

Error! Purifier off 
Error! Acid off 
Check ORP sensor 

The measured ORP is out of range and may be 
caused when the sensor is not properly connected 
or if the sensor is past its useful life.  Out of range 
ORP measurement is below 100 mv or above 900 
mv.  Chlorine and acid are not fed under these 
conditions, until corrected.  

Check and secure ORP connections. 
Replace ORP sensor. 

Error! Purifier off 
Error! Acid off 
ORP overfeed 

The measured ORP has not reached its set point 
within a user programmable time, between No 
ORP Overfeed to 120 minutes.  The factory setting 
is “No ORP overfeed”.  Chlorine and acid are not 
fed under these conditions, until corrected. 

Clear the ORP overfeed warning by 
programming ORP overfeed OFF and back ON, 
pg. 36. 
Check the operation of the purifier mode by 
ensuring proper salt, pH, and stabilizer levels. 
Check and clean ORP sensor. 
Check “Other conditions” on pg. 47. 

Error! Purifier off 
Error! Acid off 
Check pH sensor 

The measured pH is out of range and may be 
caused when the sensor is not properly connected 
or if the sensor is past its useful life.  Out of range 
pH measurement is below 4.0 or above 9.9.  
Chlorine and acid are not fed under these 
conditions, until corrected.
