A.1.3.5: Is the size of the unit adapted to the swimming pool?
ESC, ESCpH and ESR units are designed for private pools not exceeding 200
m3 (meters cubed). For semi-public or public pools, larger units such as units in the range of SC
Max are more appropriate.
A.1.4 :There is no chlorine in the water
In salt chlorination applications, the amount of chlorine in the water is often very limited (from
0.5 ppm to 1 ppm) so the owner may not feel that the unit is working correctly. We have to first
ensure that the unit is working; the following questions will enable this to be established:
A.1.4.1: Does the display of the unit show 100 when the unit operates?
Make sure that the chlorine production control is at maximum, if the display is showing 100,
(between 95 and 105), the problem does not come from the unit as it is functioning correctly. If
this is the case the water chemistry is likely to be incorrect, refer to section A.1.3.2
If the display does not show 100, (one or two red alarms ON), refer to section A.1.1.
A.1.4.2: How did you check the presence of chlorine?
How was the chlorine measured? Was a test kit used? If a test kit was not used then the test will
be inaccurate. The presence of chlorine should be checked by taking a water sample at the eye
return of the pool water, when the salt chlorinator is in operation.
A.1.4.3: Is there some stabilizer in the water?
Check water for presence of stabilizer, there should be between 40 & 70 ppm of stabilizer to
protect against chlorine evaporation from UV. Refer to section
A.1.3.3
