Installing the backup battery

1. Press the Power button to turn the unit off, then unplug the unit.

2. Open the bonnet: Press and hold the latches on both sides of the bonnet. 

• Litter-Robot 4 and Litter-Robot 5: Lift and rotate the bonnet to its open position.
• Litter-Robot EVO: Remove the bonnet completely and set aside. 

3. Remove the globe: 

• Litter-Robot 4 and Litter-Robot 5: Using the handle on top of the globe, lift it off the base.
• Litter-Robot EVO: Lift the globe off the base by holding the rib located at the top of the globe entrance. 

4. In the base, locate and remove the screws holding the motor cover in place with the use of a Phillips-head screwdriver. 

• Litter-Robot 4 has four screws. 
• Litter-Robot EVO and Litter-Robot 5 both have three screws.

5. Connect the battery, making sure to connect the leads and terminals correctly: RED lead to the RED terminal and BLACK lead to the BLACK terminal.

6. Insert the battery into the pocket. Reinstall the motor cover using the screws provided.

7. Replace the globe: 

• Litter-Robot 4 and Litter-Robot 5: Hold the globe by the handle and slide it back into the base. Ensure the back of the globe is sitting flush in the rear bearing pocket.
• Litter-Robot EVO: Hold the globe by the rib located at the top of the globe entrance and slide it back into the base. Ensure the back of the globe is sitting flush in the rear bearing pocket. 

8. Close the bonnet:

• Litter-Robot EVO: Replace the bonnet by aligning the tab at the back of the bonnet with the slot in the bonnet hinge. Rotate the bonnet downward with light pressure on the sides so that it hugs the globe. This will help ensure proper alignment of the bonnet latches in the base.
