A single press of this button decreases chlorine production by approximately 5%. To turn OFF chlorine production it is necessary to press the button several times to make sure all chlorine indicator LEDs are off.

To Permanently set the polarity change frequency, follow the directions below:

•Start with the unit “OFF”.
•Press and hold the “DECREASE” button.
•Turn the unit “ON”.
•Release the button and the selected reversing time will display. The default will be set to 7 hours, and LED 7 will display. If LED 4 displays, this indicates that the reversing time is 4 hours, and this can be increased by increments of 1 hour which will correspond with the number of LEDs displayed. If LEDs 1, 2 and 3 display this means the reversing period is 10 hours.
•To change the reversing hours, press the “DECREASE” or “INCREASE” button to switch from one reversing hour to another.
•Once you have selected the reversing time you require, turn the unit “OFF”. The new setting will apply next time you turn the unit “ON”.

The ARC Series Salt and Mineral Chlorinator can be set to “Chlor Boost” (Chlorine Boost) for 24 hours by default and automatically sets the chlorine output to 100% during that time. To enter chlor boost hold the “+” and “-“ buttons in simultaneously for 3-5 seconds. After releasing the buttons, the LED’s 2 and 4 will flash on for 5 seconds to indicate the unit has entered “Chlor Boost”. It you wish to change the “Chlor Boost” time setting you can do so by pressing the “+” or “-“ buttons this will cause the unit to cycle through settings.

Pressing “+” will have the effect of increasing the hours from 24 up to 28, 32, 36 and back to 4, 8, 12, 16, 20, 24 hours respectively. Pressing “-“ will have the effect of decreasing the hours from 24 to 20, 16, 12, 8, 4 and then back up to 36, 32, 28 and 24 hours respectively.
LED’s 1 through to 10 will turn on for 5 seconds and then off for 1 second to indicate that “Chlor Boost” has been activated.

To turn off “Chlor Boost” at any time before its running time, press and hold the “+” and “-“ buttons together for 3-5 seconds. The unit will indicate that it is deactivating “Chlor Boost” by causing the “flow fault” LED (LED 12) to flash three times and then the unit will revert to its normal function with LED indicating regular output.
