Flow Sensor: A ow sensor assures that there will always be adequate water ow through the SC-75. If the SC-75 is not
properly plumbed and/or does not receive adequate water ow, no chlorine will be produced.
Temperature Sensor: To protect the SC-75 from operaon and potenal damage when the temperature of the pool water
falls below 11° C, ±1.67° C, the temperature sensor switches the cell o, illuminates the COLD WATER light and no chlorine
will be produced.
Salt Sensor: Two (2) salt sensor probes in the SC-75 are acvated each me the SC-75 is switched on and again during
every 12 hours of connuous running. At each of those mes, the salt level LED indicator lights ash in a scrolling sequence
for two (2) minutes to indicate that the SC-75 is in analysis mode. Aer two (2) minutes, the LED indicators lights will signal
one (1) of three (4) salinity ranges. For more informaon, see “Salt Level Status LEDs”.
Note: The salt sensor reading is within +/- 500 ppm accuracy.
SC-75 Power Center
The power supply is connected with the pool circulaon pump electrical source so that the SC-75 only operates when the
pool pump is on. The Power Center should be mounted vercally on the wall up to three (3) meter away from the cell. The
Power Center contains the transformer, fuse, and connector to the cell. A fuse holder is mounted on the boom of the Power
Center for addional protecon. There are no other controls or lights on the Power Center. For informaon about installing
and proper use of the Power Center, see the “SC-75 Power Center Installaon Guide” .
The SC-75 Power
Center does NOT
control the pump. The SC-75 Salt
Chlorinator only produces chlorine
when the pool pump is on.
Before plugging or
unplugging the SC-
75 Salt Chlorinator to the Power
Center, rst switch o the AC
power to the Power Center.
Loop Plumbing Diagram
The SC-75 Salt Chlorinator is designed to operate with water ow rates from 5.7 m³/h to not exceed 24 m³/h. For ow rates
over 18 /h minute you must use a bypass loop (as shown below) for best chlorine producon. Installaons with ow
rates over 18m³/h include those that have in-oor cleaning systems or booster pumps. These systems MUST use a bypass
loop with the SC-75 with a ow control valve that assures that the ow through the SC-75 is maintained within its designed
operang water ow rates.
