TROUBLESHOOTING
Note: If the Zodiac EZ SALT Chlorine Generating Device and pump are running it is normal for a
cloud of small bubbles to be produced in the cell, indicating chlorine is being produced.
Problem A: Water looks clean but no chlorine residual reading.
To test for chlorine residual, switch on the filtration system and adjust the Zodiac EZ SALT
Chlorine Generating Device to maximum output. After a few hours, take a water sample from the
pool. Test this water with your test kit. Chlorine residual should measure between 1 and 3 ppm.
REMEDY:
•
Adjust total alkalinity to 100-120 ppm.
•
Adjust the pH within the range 7.2 – 7.8.
•
Make sure your cell is clean.
•
Check cyanuric acid (stabilizer) level.
•
Increase the setting of the output control.
•
Increase the running time of the pump, filter and Zodiac EZ SALT Chlorine Generating
Device. Make sure that the filter is clean and functioning properly.
•
Add salt if level is below 3200 ppm. Do not operate the EZ SALT Chlorine Generating
Device until all the salt has dissolved as this will cause damage to the unit.
•
Superchlorinate with the 'boost' button or manually shock the pool with sodium
hypochlorite (liquid chlorine).
Problem B: Pool is green and no chlorine reading
Chlorine is still considered the most effective way of destroying algae and bacteria in your pool
water. A chlorine residual of 1 to 3 ppm is considered desirable.
REMEDY:
Super chlorinate ('boost') or manually shock the pool with sodium hypochlorite (liquid chlorine).
This will raise the chlorine residual to a very high level for a short period of time, and reduce
chlorine demand.
To super chlorinate with the Zodiac EZ SALT Chlorine Generating Device:
i)
Backwash the filter.
ii)
Adjust the pH to within the range 7.2 – 7.8. See 'Tips on Water Chemistry'.
iii)
Press the button marked 'boost'. The EZ SALT Chlorine Generating Device
automatically increases its output and runs for approximately 24 hours of pump
runtime.
iv)
After 24 hours, backwash the filter.
v)
Re-adjust the pH to 7.2 – 7.8.
vi)
Check the chlorine reading.
vii)
If there is still no chlorine residual, apply a manual shock as described below. If
the chlorine reading is improved but is still too low, repeat steps (iii) to (vi) until
the chlorine reading is satisfactory.
To manually shock with chlorine or oxidizing agents:
i)
Backwash the filter.
ii)
Adjust the pH to within the range 7.2 – 7.8 (See 'Tips on Water Chemistry').
iii)
Follow instructions of shock product being employed.
iv)
After shock dosing, re-adjust the pH to within the range of 7.2 – 7.8 and check
the chlorine level before using the pool. The chlorine residual should be 1 – 3
ppm.
