7. PROBLEMS / SOLUTIONS: ____________________________________________________________________________________
Any action required to solve possible problems in the equipment should always be performed with the equipment disconnected from the
mains. Any problem not indicated in the following list should be solved by a qualified technician.
PROBLEM
Production indicator always indicates "0" at all production levels
It is not possible to turn on the power supply.
Free chlorine levels in the water are very low.
pH controller always show extreme values, or readings are unstable.
Impossible calibration of the pH sensor
Slow response of the pH sensor
SOLUTION
Check the electrodes.
Verify connections between power supply and the electrolysis
cell.
Check salt concentration.
Check that the system is properly connected to 230 V/50-60 Hz in
the control box of the pump.
Check the estate of the fuse located at the bottom of the power
supply.
Check that the system produces chlorine in pool jets.
Verify that the water Chemicals parameters (pH, combined
chlorine, isocyanuric acid, etc.) are correct.
Increase filtering time.
Add chlorine stabilizer (cyanuric acid) until a concentration of 25 –
3
30 g/m is achieved.
The cable of the pH sensor is damaged. Clean the contacts or
replace the cable.
The pH sensor has an air bubble in the membrane area. Hold the
sensor in vertical position.Shake it lightly until the bubble moves
up.
Sensor fault. The connection cable is too long or it is too near to
sources of electrical interference (motors, etc.). Replace the
sensor. Locate the unit nearer to the sensor.
Polluted or expired calibration solution.
Blocked sensor membrane. Check the membrane is not
damaged. Clean the sensor with diluted acid in water, shaking it
lightly.
Sensor fault. Replace the sensor.
Sensor electrostatically charged. During the calibration phase, the
sensors should not be dried with paper or cloth. Clean it exclusively
with water and shake it lightly.
Insufficient renovation of the analyzed water (no flow through the
sample point). Ensure that the tip of the sensor is submerged in the
water at the sample point, and that no air bubbles are present.
