Troubleshooting pH Out Of Range pH is measured on a scale ranging from 0 to 14, with pH 7.0 considered neutral. pH below 7.0 is considered acidic and above 7.0 is alkaline. pH is a significant variable in determining water quality as it affects sanitizer activity, color, and human compatibility with the water. The proper pH range for swimming pools and spas is between 7.2 and 7.8. pH Low A pH below 7.2 will cause corrosive water resulting in possible damage to the filtration components and pool surface as well as bather discomfort. First, test the pool/spa water with a phenol red pH test kit. If the pH on the test kit agrees with the controller and the pH is below 7.2, check the pH correction chemical level. If the manual test does not agree with the controller clean the sensor. pH High A pH above 7.8 will cause scaling on the pool surface, plumbing, and filtration equipment as well as cloudy water, inefficient use of sanitizer and bather discomfort. First, test the pool/spa water with a phenol red pH test kit. If the pH on the test kit agrees with the controller and the pH is above 7.8, check the pH correction chemical level. If the manual test does not agree with the controller clean the sensor. pH Overfeed The pH Overfeed timeout occurs when the CAT 6000 has been feeding chemicals for a time greater than the selected maximum feed time and has not reached its setpoint. A properly selected Overfeed timeout prevents the unit from continuing to feed chemicals when the chemical supply has been diminished or a chemical feeder has become clogged or broken. First, check the chemical supply and chemical feeder. If both are in order, check the Overfeed timeout setting as it may need to be increased to keep up with chemical demand. pH Tank Low The pH Tank Low alarm will sound when the chemical being fed falls below the optional optical level sensor in the tank. First check the chemical level. If the level is above the sensor, check the sensor for obstruction or scaling. 34 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

Troubleshooting
pH Out Of Range
pH is measured on a scale ranging from 0 to 14, with pH 7.0 considered neutral. pH below 7.0 is
considered acidic and above 7.0 is alkaline. pH is a significant variable in determining water quality
as it affects sanitizer activity, color, and human compatibility with the water. The proper pH range
for swimming pools and spas is between 7.2 and 7.8.
pH Low
A pH below 7.2 will cause corrosive water resulting in possible damage to the filtration components
and pool surface as well as bather discomfort. First, test the pool/spa water with a phenol red pH
test kit. If the pH on the test kit agrees with the controller and the pH is below 7.2, check the pH
correction chemical level. If the manual test does not agree with the controller clean the sensor.
pH High
A pH above 7.8 will cause scaling on the pool surface, plumbing, and filtration equipment as well
as cloudy water, inefficient use of sanitizer and bather discomfort. First, test the pool/spa water
with a phenol red pH test kit. If the pH on the test kit agrees with the controller and the pH is above
7.8, check the pH correction chemical level. If the manual test does not agree with the controller
clean the sensor.
pH Overfeed
The pH Overfeed timeout occurs when the CAT 6000 has been feeding chemicals for a time
greater than the selected maximum feed time and has not reached its setpoint. A properly selected
Overfeed timeout prevents the unit from continuing to feed chemicals when the chemical supply
has been diminished or a chemical feeder has become clogged or broken. First, check the chemi-
cal supply and chemical feeder. If both are in order, check the Overfeed timeout setting as it may
need to be increased to keep up with chemical demand.
pH Tank Low
The pH Tank Low alarm will sound when the chemical being fed falls below the optional optical
level sensor in the tank. First check the chemical level. If the level is above the sensor, check the
sensor for obstruction or scaling.
