When switched on for the first time, the DuoClear will go through an initialization sequence, indicated by
the yellow light being illuminated. After a short period the light will switch off and the system will begin
normal operation.
The chlorinator defaults to the ‘zero output’ state. The user can then select the desired output level. Start
the operation of the DuoClear at maximum output.
After initial startup, the micro-processor in the DuoClear retains the chlorine output and super chlorinate
settings, and the polarity reversal time in memory when the unit is turned off, unless the setting was
changed less than one minute before turning off.
Operating Tips
•
Run the filtration and chlorination system for at least 6 to 8 hrs per day.
During very hot weather it may be necessary to run the system for additional hours. In winter, where
pools remain open, run the filtration system for about 4 hours per day. Shorter periods will help
lengthen the life of the cell electrodes.
•
Maintain the free chlorine residual in the pool at 0.5 - 1.0 ppm.
Increasing the daily operating period of the system increases the free chlorine reading, and a shorter
operating period reduces the chlorine reading. Likewise, operating the chlorinator at maximum output
will produce a higher chlorine reading than operating the chlorinator at a lower setting.
•
Maintain chlorine stabilizer (cyanuric acid) level between 40-100 ppm.
Specific requirements will vary depending on the regional climate. Chlorine stabilizer helps to keep a
satisfactory free chlorine reading in hot sunny climates. Extremely hot and sunny climates will require
readings at the higher end of the range. Refer to Stabilizer Requirements chart in Maintenance.
•
It is absolutely essential that the pH of the pool be maintained in the range of 7.2 - 7.8.
Regularly test or have a pool professional test the pH level in the pool. The effectiveness of chlorine
as a sanitizer is significantly reduced as the pH rises. At a pH of 8.0, nearly all of the chlorine being
added to the pool is wasted, and it is almost impossible to maintain a satisfactory free chlorine
reading. Additionally, pH readings at 8.0 and higher increase scale formation which may require
manual cleaning of the cell.
•
Perform regular maintenance checks as outlined in the Maintenance section.
