installed. Panel size is critical for a proper t. To verify panel
requirements and dimensions, refer to the Sub-Zero design
guide at subzero.com/specs.
Finish all sides of custom panels. They may be visible
when the door is open or through the window of glass door
models.
MODELS UC-24R AND UC-24C(I)
Remove the two panel mounting brackets attached to the
front of the door. Place the custom overlay door panel face
down on a protected work surface. Position the plastic template provided, ush with the lower edge of the panel. Verify
proper location for right-hand (RH) or left-hand (LH) door
swing. Mark the holes, remove template and drill pilot holes
for the brackets. Secure mounting brackets with screws
provided.
If the template is not available, position mounting brackets
as indicated in the illustration below.
To install the custom door panel, partially insert a screw in
the center of each mounting position on the hinge side of
the door. Engage the tabbed bracket to the handle side
of the door, then slide the hinge side mounting bracket onto
positioning screws. Slotted holes on the mounting bracket
should slide under screw heads to support the panel. Refer

PANEL INSTALLATION
Custom Door Panel
MODEL UC-24BG
The custom overlay door panel is attached using screws
provided through the door frame. Screw locations are
marked on the back of the custom panel using tenon centers inserted into holes of the door frame.
With the unit secured and door closed, hold the custom
panel in desired position on the door. Lightly tap the front
of the panel to locate mounting positions. Remove tenon
centers. Refer to the illustration below.
The door frame has mounting holes to accommodate
Sub-Zero accessory handles. If handle mounting holes are
not utilized, the handle should be attached to the custom
panel prior to mounting. Screw heads may need to be countersunk into the panel for proper alignment.
To mount the custom panel, open the door and use predrilled holes to position the panel. Drive screws into the
panel through black tape on the door frame. Screw holes
are hidden behind the door gasket. Use as many screws as
necessary to secure the custom panel. Refer to the illustration below.
Adjustments can be made to the custom panel with a few
mounting screws in place, but not fully tightened. Once the
proper position is achieved, install and secure all screws.
Cover holes on the inside of the door frame with the cover
patches or plugs provided.
WARNING
Follow all city and state laws when storing, recycling or
discarding unused refrigerators and freezers.
