I would glance at the manual and see if there is a way to retract the wheels. Else you might try something like a shim under both sides (popcycle stick perhaps?) that you can remove when you need to slide it out from the wall.

There are two screws in the front, near the wheels which need to be lowered to stabilize the fridge. Attached to the bottom of the screws are rubber pads which make contact with the floor. They are also used to level front/back and side/side. To access the screws, pull off the black cover at the very bottom of the fridge. You will see two hex bolt heads, one on each side. Using a socket, turn the bolts to lower screws/pads until the fridge is resting on them. Then further adjust them to level. This is all written up in the manual.

Thanks - I've looked through the manual, however not a length. I'll get it out this weekend for some "bed" time reading! :-)

PS: normally, you want the fridge to not be perfectly level, but to lean backwards very slightly so the doors will close on their own. This will also assure (for units that have them) that the defrost water drain operates correctly.
