CAL Err
If this error is displayed
during the calibration
phase and cycle it is as
a result of:
1). Your pH probe is not
working properly
2). Your buffer solution
is polluted
3.) You have water/
oxidisation in the
probe connector
1). Change the probe
2). Change the buffer
solution
3). Change over the
probe
Alarm Alr Err
If the pH is lower than
pH 5 or above pH 9, this
alarm will be displayed
and dosing will be
stopped.
Adjust your water
parameter manually so
that it comes back to the
required value of these
parameters:
- Total alkalinity
- TH (hardness)
- pH
The dosing pump will
restart as soon as the
pH reading
