DANGER
Use a jack to lift the refrigeration unit off the ground
just far enough to remove the leg. Place blocking
underneath the refrigeration unit. Do not work
underneath a raised unit without proper blocking. Do
not lift the unit more than necessary to remove the
leg. Lifting the unit too far can make the unit unstable.
1. Place a jack underneath the refrigeration unit as close
as possible to the leg (Figure 16). Lift the unit just high
enough to remove the leg from underneath the
refrigeration unit. Place blocking underneath the unit to
prevent the unit from falling during removal of the leg.
2. Remove four screws from the upper portion of the leg.
3. Remove the leg from the refrigeration unit.
4. Reverse the above steps to install a replacement leg.
