What does “HIGH SALT/RESET” mean on my POOL LAB Water Filtration Systems?

J

If your POOL LAB Water Filtration Systems displays “HIGH SALT/RESET” and resets after 30 seconds, it indicates the software detected a drop in the power supply voltage. Check the salt level in the water and inspect the cell for debris or damage. If the salt level is fine and the problem persists, the unit needs servicing. This message may also appear immediately after adding salt to the water. In this case, run the filter pump for some time without the chlorinator connected so that the newly added salt has time to dissolve and disperse into the water. When adding salt to the water try to ensure it is added as far away from the filtration system suction points as possible. Close main drain suction valve where applicable and remove any suction driven pool cleaners from the water. Never add s...

DIAGNOSTIC MESSAGES

CHECK SALT

Message indicating low conductivity, possibly due to low salt or cold water, affecting chlorine production.

CHECK SALT CELL OFF

Message indicating critically low conductivity, with power to the cell turned off to prevent damage.

HIGH SALT
