CPU BOARD REPLACEMENT
Required Tools:
T27 Torx
Procedure:
1. Adjust the Fowler to approximately 25−30. Unplug the bed power cord from the wall socket.
2. Properly ground yourself (see page 39 for static discharge precautions).
3. Using a T27 Torx, remove the two screws holding the head end litter access cover and remove the cover.
4. Disconnect all cables at the litter CPU board. Note the locations of the cables so they will be connected
properly to the replacement litter CPU.
5. To remove the board from the litter standoffs, pull out on the retention clips and lift upward on the board.
6. Install the new board and reconnect all cables.
7. Reinstall the litter access panel and plug the bed power cord into a properly grounded wall receptacle.
8. When a new CPU board is installed, a “burn−in” procedure must be done (see below). If your
bed is equipped with a scale system, scale calibration must also be done (see page 81).
9. Test bed operations before returning the bed to service.
