Litter-Robot 4: Carbon filter installation guide

Litter-Robot 4 is equipped with a flexible carbon filter pad that is installed on the outer bottom area of the globe. This filter sits directly over the waste drawer to absorb odors. 

The carbon filter is not required for the unit to function. The OdorTrap® Packs may be used instead of the carbon filter.

1. Press and hold the Cycle and Empty buttons on the control panel for 3 seconds, or tap "Replace Filter" under Controls in the app.
2. A clean cycle will begin; the cycle will pause when the globe reaches the "replace filter" position.  
3. Open the bonnet: Press and hold the latches on both sides of the bonnet, then lift and rotate the bonnet to its open position to reveal the filter pocket.
4. Open the filter cover and replace the carbon filter as needed. (Under normal use, 1 filter should last approximately 1 month.)
   

   Note: If the filter cover is not fully seated, it may contact a safety bar during the cycle. Make sure it is snapped in properly and cleaned/wiped.

5. Close the bonnet: Rotate the bonnet down­ ward over the globe and push down on the bonnet from the top to make sure it is latched and secure.
   

   Note: If you removed the bonnet completely, be sure to latch the center tab on the bonnet into the catch clip on the unit frame behind the bezel before closing the bonnet.

   
   
6. Press the Cycle or Reset button to resume the clean cycle; when the clean cycle has ended, press the Reset button to zero the weight sensors.
