TROUBLESHOOTING

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

60% 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 – 7.6.

· 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 chlorinator. Make sure that the filter

is clean and functioning properly.

· Add salt if indicated by ‘Add Salt’ light. Do not operate the Clearwater until all the salt

has dissolved as this will cause damage to the unit.

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 30- 100 ppm depending on geographical climate. Refer to stabilizer chart.

Use of algaecides

Although not normally needed with a Clearwater chlorinator, algaecides may be used. Al-

ways 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 liquid chlorine (sodium hypochlorite) until a measurable

free chlorine residual reading is obtained.
