Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solut ion (ex-
ample: Kay-5r). USE WARM WATERAND FOLLOW
THE MANUFACTURER’S SPECIFICATIONS. If
another approved cleaner is used, dilute it according
to the label instructions. (IMPORTANT: Follow the
label directions. TooSTRO NG of a solution can cause
parts damage, while too MILD of a solution will not pro-
vide adequate cleaning.) Make sure all brushes pro-
vided with the freezer are available for brush cleaning.

graspt he o-ring. Apply pressure in an upward direct ion
until the o-ring pops out of its groov e. With the other
hand, push the top of the o-ring forward andit willroll
out of the groove and can be easily removed. If there
is more than one o-ring to be removed, always remove
the rear o-ring first. This will allow t he o-ring to slide
