TAKE MEASUREMENTS
All Units
1. Refer to the cooktop installation instructions for dimensions of
cooktop, countertop cut-out, and cabinet requirements. Mod-
els RMDD3004 & RMDD3004EX will fit in most 30" wide
cabinets. Models RMDD3604 & RMDD3604EX will fit in most
36" wide cabinets. Models RMDD4804 & RMDD4804EX will
fit in most 48" wide cabinets. However, it is recommended that
oversized cabinets be used for easier installation.
2. Cooktop depth can vary greatly from one to another. This may
cause the fit of these two appliances to be rather tight.
Pay special attention to the areas of potential interference high-
lighted above. A countertop with (A) a raised lip and/or (B) a
backsplash may not allow enough flat countertop for a proper
installation. Note that 2" of flat countertop is required behind
cooktop and that 1-3/4" is necessary between the back edge of
the cooktop and the inside of cabinet back.
