More and Less Output Buttons
The More and Less buttons control the percentage of time of each hour that the SC-75 Salt Chlorinator is producing chlorine
while the pump is on (see Sanitizer Output LED indicators above). The lights act as a bar graph: the more lights that are on,
the more chlorine is produced. Flip the panel cover up to access the More, Less and Boost On/Off buttons. To exit Boost
mode, press and hold both the buttons.
More: Increases the time the cell produces chlorine.
Less: Decreases the time the cell produces chlorine.
Boost On/Off: Press and hold both the More and Less buttons together to activate Boost mode on or off. Boost mode sets the
sanitizer output to run 100% for the next 24 hours of pool pump run time. If the time clock switches off the pump cycle, then
switches power back on the next day, Boost mode will continue until 24 hours has elapsed since Boost mode was turned on
or Boost mode is canceled by the user. The Sanitizer Output display will show a pattern LED display to indicate Boost mode.
Self-Cleaning
The self-cleaning feature reduces scale buildup on the blades of the SC-75. The self-cleaning cycle tends to reduce the life
of the SC-75, therefore, it should be used only to the extent necessary to minimize the scale buildup on the blades. The self-
cleaning cycle can be adjusted to run every 3, 4, or 5 hours, whichever is the optimal for your particular pool conditions in
order to minimize scale buildup but maximize the life of the SC-75. It is factory set to two (2) hours for the first 30 days of
operation, then automatically switches to three (3) hours. To change the self-cleaning cycle, press and hold the LESS button
for three (3) seconds. The sanitizer output display will show the number of hours in a bar graph style. The number of output
LEDs lit is the number of reverse hours. Pressing More or Less button will change this setting.
