If you use a Pool Pump Timer. The Association of Pool & Spa Professionals (APSP) recommends that all
water in a residential pool pass through the ﬁ ltration system at least once every 12 hours (referred to as pool
water turnover). However, many factors have an effect on actual pump and ﬁ lter system run times. Pool
size, source of water, direct sun light, indoor/outdoor, screened/unscreened, ﬁ ltration system, cold or hot
weather, swimmer load, rain, organic debris, algae, etc., are all factors which contribute to either more or
less pool pump and ﬁ lter system run times. Because of these differences, it is extremely difﬁ cult to set an
initial run time (starting point) for the pool pump and chlorinating system.
Try initially setting the Pool Pump Timer to 12 hours. It will take a few days to get just the right pool
pump operating time. Adjust accordingly using the steps listed below ( Section 5.4.2, steps 1-5 ). When
the AquaPure is wired with a Pool Pump Timer (See page 6 Figure 2) results will vary greatly from one
pool installation to the next, so this should be discussed with either the pool builder or the local pool
professional. The key points are:
• Operate pool pump at least the minimum time needed for good ﬁ ltration.
• The Pool Pump Timer reduces energy consumption.
NOTE Exception - For Cold Weather Operation: If the AquaPure is run 24 hours a day through the winter, extremely
cold water temperatures can affect Cell life. Sometimes it will be necessary to run the AquaPure at a very low
production rate of 10% to 20% or to turn the unit off. See Winterizing on page 29.
NOTE The generator only operates when the pump is running. During hot weather months you may need to increase
pump run time to allow sufﬁ cient chlorine production.
Shocking (Super Chlorination) is recommended before pool startup. Start out with good pool water
from the beginning. The AquaPure will build up a sufﬁ cient level of chlorine for sanitation in several hours.
However, if pool water has a high demand from the startup the AquaPure will not be able to produce enough
chlorine to reach break point chlorination. So, it is best to super chlorinate from an outside source at the
time of pool startup. Then, wait until the chlorine level has returned to 1 to 3 PPM before turning on the
Turn on the pool pump switch or Pool Pump Timer. When the AquaPure is ﬁ rst turned on (cold),
the unit will beep. Next it will self-calibrate the Flow/Temp/Salinity Sensor. After going through an
internal test and calibration, the LCD will display the current setting for Chlorine Production (00% to
100%). During the calibration period "Wait" will appear. "Wait" means the unit is self calibrating and
doing internal testing. This usually takes less than 6 minutes.
Check salinity level by pressing the

NOTE If still less than 3.0 gpl refer to pages 18 through 20 and adjust salt level. (Maintain the Recommended
Salinity Level of 3.0 to 3.5 gpl). If salinity is below 2.0 gpl the AquaPure will automatically turn the cell off
until the salinity is raised above 2.0 gpl, since operating with low salt will damage Cell. Likewise, if salinity is
above the range of measurement the AquaPure will automatically turn the cell off until the salinity is lowered
to a measurable level, since operating with high salt will damage the control center. If salinity is greater than
3.5 gpl, see Troubleshooting, page 30.
Adjust the Chlorine Production to 50% by pressing the arrow button
button. It should read between 3.0 gpl and 3.5 gpl. If it
