  3. Wipe away all the moisture with a cloth. It’s important to keep moisture out of the battery compartment to avoid corrosion.
  4. Open the battery compartment and remove the old batteries. Safely dispose off the batteries.
  5. Insert new batteries from recommended brand and firmly close the battery compartment. (Manufacturer’s have varying characteristics in their batteries. Our testing has shown batteries from ‘Energizer’ brand perform the best in the environment that WaterGuru is exposed to.)

  7. Place the Sensor unit back in the skimmer with the cover on top of the skimmer.

How to change WiFi?

WiFi settings for your unit can be changed in the WaterGuru App. WaterGuru App uses Bluetooth (similar to connecting to your car) to communicate with your unit. You will need to be close to the unit when trying to change the WiFi settings for your unit. You can find the instructions here.

What is the WaterGuru Cassette and where can I get a replacement Cassette?

WaterGuru Cassettes hold strips of sensing pads that measure chemistry. You can purchase a cassette right here on our website.

How do I replace the Cassette?

  1. Remove the Sensor unit from the skimmer.
