7. TROUBLESHOOTING: ________________________________________________________________________________________
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 an IDEGIS technician.
PROBLEM SOLUTION
Production indicator always indicates “0” at all production levels Check electrodes.
Verify connections between power supply and the electrolysis
cell.
Check salt concentration.
The power supply is not turned on. Check the system is properly connected to 230 V/50-60 Hz in the
command box of the pump.
Check th estate of teh fuse located at the bottom of the power
supply.
Free chlorine levels in the water are very low. 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 –
30 g/m
3
is achieved.
pH/ORP controller always show extreme values, or readings are
unstable. The cable of the pH/ORP sensor is damaged. Clean the contacts
or replace the cable.
The pH/ORP 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.
Impossible calibration of the pH/ORP 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.
Slow response of the pH/ORP 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.
