TROUBLESHOOTING
Excessive Calcium Build Up on Cell
(even after cleaning)
1.
The current should reverse every 4-6 hours. This can be tested
by switching off the Cell switch while it is running and turning it on
after 20 seconds (not less). The Cell current should now be in the
opposite direction. Contact your Pool Shop or the Manufacturer if
this does not happen.
Low Chlorine Residual or Production:
1.
Check for correct PH or insufficient stabiliser. Lift stabiliser to
60ppm in midsummer and during peak periods (normal range 40
- 60ppm).
Very Low Chlorine Production:
1.
Check that the Cell is clean and the salt level is 3000 ~
3500ppm.
2.
Check if the Cell switch lights up and if not check the
Fuse/Circuit breaker.
3.
Check that the Sensor has water covering it and not air. The
Cell head should be placed so that the sensor “Peg” is on the
bottom.
4.
Remove and dry the Cell plates and examine every electrode to
see if the black coating looks patchy. They may require cleaning
and drying before this can be seen. If this is the case then the Cell
might need replacing.
Note: Rapid damage like this is normally the result of far too low
salinity or filling the pool with fresh water put direct into the
skimmer box
Nil Chlorine Production:
1.
Check fuse/Circuit Breaker.
2.
Check that the Pump is running and water is flowing through
the Cell.
3.
Check that the Sensor Peg is covered with water and not
air/bubbles.
4.
Check that the sensor is not covered with Calcium.
5.
Check the Junction Box to see if all the connections are tight. If
there is any sign of melting or burning of the Junction box it must
be replaced. This is caused by either leaving a wire loose or salt
water getting under the cover causing electrolysis of the
connections.
6.
If none of the above then contact your supplier. If the residual
test is low or the Pool remains cloudy, then the chlorine is being
lost due to high chlorine demand caused by contaminants. If PH
and stabiliser tests are correct a shock treatment with an oxidiser
agent is advised. If the Pool has not been maintained correctly,
super-chlorination may be required
