How to Understand the Purline Salt System Control Operations

When the main switch is in the off position the box still has power but no chlorine will be generated. 

Note: The power LED will still be on.

 When the main switch is in the auto position the salt system will create chlorine in accordance with the desired % of the chlorine output dial.

Note: The power and Generating LEDs will be on

When the main switch is in the On/ Super chlorine position the system will create chlorine at 100% until power is taken away from the system or turned back to either auto or off.

This dial is used to adjust the chlorine the salt system will generate from 5% to 100%. 

Each time you push the system status button the display will show your diagnostic readings. 

Note: Steps 6-14 will be from the start when the system is first powered on.

When the system is first turned on. This is the salt level value that is memorized.

Note: This can be changed through recalibration. Please check out the How to Recalibrate the Pureline Salt System guide.

Pressing the button 1x. This shows the temperature.

Pressing the button 2x. This will display the cell voltage.

Note: This should be around 20-26 volts when chlorine is being generated otherwise when off it will read 30 volts. 

Pressing the button 3x. This will display the cell current. 

Note: The typical reading for the current is 2.00-8.00 while the system is generating chlorine. When the system is off the current should be 0.00.

Pressing the button 4x will display the desired output depending on the dial. If the dial is on 20% the display output should read 20% as well.

Pressing the button 5x will display the instant salt in parts per million. 

Pressing the button 6x will display the Pureline salt system product name. 

Pressing the button 7x will display the software revision of the board.

Pressing the button 8x will display the cell type that matches your connected cell.

Note: If you need help changing the cell type please check out How to Change the Settings on a Pureline Salt System.

This LED illuminates when there is power going to the Pureline salt system box.

This LED illuminates when the salt system is in its normal operation mode. 

Note: If this light starts blinking it means the water is too hot or too cold. The chlorinator stopped producing chlorine. 

This LED turns on when the main switch is on super chlorination. 

This LED indicates that the system is being controlled by a remote controller.

This LED will illuminate when the flow switch has detected no flow in the pool. 

Note: This can be caused by a dirty filter, a bad flow switch, or if you have a variable speed pump and the speed is too low.

Note: For steps 21 and 22 you should check your actual salt level in the water before adding salt. Salt systems box readings can be off by a couple of hundred parts or if the cell is bad or dirty it can give faulty readings. 

When this LED is blinking. It means the salt level in the pool is too low  (below 2500ppm). The salt generator is going to create chlorine at low efficiency.

When the LED is solid this means the salt level is so low that the generator has completely stopped.

 When this light is illuminated the salt level in the water is too high and it has stopped creating chlorine.

Note: Check the actual salt in the pool to make sure the salt is high. If the salt is too high then water will have to be drained and added to dilute the salt in the water.

Note: For steps 25 and 26 the check cell LED is on a timer and will go off every 500 hours. To reset the timer and make the LED go away hold down the system status button for 3-5 seconds.

If the check cell light is blinking it means that the cell efficiency is reduced or it is time for its regular maintenance.

This means the cell has completely stopped creating chlorine and it’s time to inspect, clean, or replace it.
