Troubleshooting
NOTE:
If the chlorinator and pump are running it is normal for a cloud of small bubbles to
be produced in the cell, indicating chlorine is also 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 Clearwater 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 80 - 120 ppm.
•
Adjust the pH within the range 7.2 - 7.6.
•
Make sure your cell is clean.
•
Check cyanuric acid levels.
•
Increase the setting of the output control.
•
Increase the running time of the filter and chlorinator. Make sure that the filter is clean and
functioning properly.
•
Add salt if indicated by ‘Add Salt’ light.
Use chlorine stabilizer (cyanuric acid) to protect chlorine residual.
This chemical acts as a sun-screen for chlorine and prevents chlorine from being too quickly
destroyed by the sun. Chlorine stabilizer is essential to prolong the life of chlorine in the pool
water. It should be added following the manufacturer’s instructions to achieve a level of 40 -
100 ppm. depending on geographical climate. Refer to stabilizer chart on page 19.
Use of algaecides.
Although not normally needed with a Clearwater chlorinator, algaecides may be used. Always
follow manufacturer's instructions for treatment. Overdosing the pool with any type of
algaecide may reduce residual chlorine measurements/reading. If this occurs, you must
manually shock pool water with granular or liquid chlorine until a measurable free chlorine
residual reading is obtained.
