CHLORINE PRODUCTON AND CONTROL
FREE CHLORINE LEVEL
A free chlorine residual of 1.0ppm to 3.0ppm must be maintained
in the pool / spa water at all times.
The ability of the chlorine generator to maintain this level will alter with respect to the
chlorine demand imposed by bather load and environmental factors.
The chlorine output level [%] is displayed on the LCD and may be altered using the UP
and DOWN buttons. This allows you to increase or decrease the chlorine production
without alteration of the operation time.
Testing for chlorine levels is very important and should be performed on a daily basis. The
sample of water to be tested should be taken at arms depth away from the pool returns.
This avoids highly chlorinated water, which has traveled directly from the chlorinator cell
and ensures the reading will be a true representation of the pools residual level.
The requirement to super chlorinate or shock dose the pool manually during periods of
high chlorine demand is highly recommended, and in some cases absolutely necessary.
When a test reveals low chlorine (or zero) chlorine, always treat manually with liquid
chlorine and investigate if the chlorine generator is operating to its maximum capacity and
for sufficient hours to meet the demand.
Contrary to popular belief, a Chlorine generator can not shock dose the pool water. It is
however beneficial especially where high bather loads exist to perform this task. Shock
dosing the water manually with chlorine, breaks irritating chloramines down and provides
for safer water with reduced chlorine demand.
ALTERING CHLORINE OUTPUT
The chlorine output may be altered in two ways:
Increasing or decreasing the operating time
Increasing or decreasing the output percentage level
Manual addition of liquid chlorine may be required during peak usage periods if the
chlorinator cannot meet the demand.
When a Pool Lab ASP add-on module is connected, the chlorine output percentage will be
adjusted automatically. However if the chlorine level is persistently too low, you may need
to increase the filtration time to allow for more chlorine production, or consider shock
dosing the water to reduce chlorine demand.
