Operation
When power is first applied to the AQR100, an initialization routine will run and during this time, vari-
ous LEDs will illuminate. This is perfectly normal and does not require any input from the user. When
the routine is finished, the AQR100 will begin normal operation.
If the water chemical levels are in the recommended range, there are three factors that you can control
which directly contribute to the amount of chlorine the AQR100 will generate:
1. filter time each day (hours)
2. the DAILY CHLORINE OUTPUT setting
3. the amount of salt in the pool
The filter pump timer/schedule should be set so that all of the water in the pool passes through the
filter at least once each day. For pools with high chlorine demand, the timer may have to be set
longer to generate enough chlorine.
Daily Chlorine Output Setting
You can adjust the amount of chlorine that is generated using the “+” and “-” button on the AQR100
unit. The DAILY CHLORINE OUTPUT LEDs will display the current setting. Push “+” to increase and “-”
to decrease the current setting. Each DAILY CHLORINE OUTPUT LED represents 6 minutes of chlorine
generation out of 1 hour. For example, if 5 LEDs are illuminated, the AQR100 unit will generate chlorine
for 5 x 6 = 30 minutes out of every hour of operation. During this time, the GENERATING CHLORINE
LED will be lit. The unit will be idle for the remaining 30 minutes at which time the GENERATING
CHLORINE LED will turn off and the STANDING BY LED will illuminate.
To find the optimum setting, start the operation with 5 DAILY CHLORINE OUTPUT LEDs illuminated. Test
the chlorine level every few days and adjust up or down accordingly. It usually takes 2-3 adjustments
to find the ideal setting for your pool and after that, it should only take minor, infrequent adjustments.
Because the chlorine demand of the pool increases with temperature, most people find they have to
adjust up at the peak of the summer and down during colder periods. The AQR100 automatically
scales back to 12 minutes of output per hour (if set higher than 12 minutes) when the pool water
is 50º - 60ºF. This protects the unit as well as prevents possible over-chlorination. The AQR100
stops generating when the pool water temperature drops below 50ºF. This is usually not a problem
because bacteria and algae stop growing at this temperature. You can override these automatic low
temperature operations by switching to SUPER CHLORINATE for a day.
NOTE: After the ideal DAILY CHLORINE OUTPUT setting has been found, you may need to raise the
setting when the pool water temperature increases significantly, when there is higher than normal
bather load or when the AQR100 Cell ages. You may need to lower the setting when the pool water
temperature decreases significantly or there are long periods of inactivity.
Prevent over-chlorination during cold weather: Check chlorine levels periodically. Most pools
require less chlorine during cold weather and the DAILY CHLORINE OUTPUT should be lowered
accordingly.
Maintaining the AQR100 System
The replaceable Cell uses the same electronic self cleaning technology as the popular Hayward
Turbo Cell. In most cases this self cleaning action will keep the Cell working at optimum efficiency.
