Check the opening where the microwave oven will be installed.
The location must provide:
Minimum installation dimensions. See "Installation
Dimensions" illustration.
Minimum one 2" x 4" (50.8 x 101.6 mm) wood wall stud and
minimum 3/8" (10 mm) thickness drywall or plaster/lath within
cabinet opening.
Support for weight of 150 lbs (68 kg), which includes
microwave oven and items placed inside the microwave oven
and upper cabinet.
Grounded electrical outlet inside upper cabinet. See
"Electrical Requirements" section.
NOTES:
If installing the microwave oven near a left sidewall, make sure
there is at least 3" (7.6 cm) of clearance between the wall and
the microwave oven, so that the door can open fully.
Some cabinet and building materials are not designed to
withstand the heat produced by the microwave oven for
cooking. Check with your builder or cabinet supplier to make
sure that the materials used will not discolor, delaminate or
sustain other damages.
For gas cooktop, we recommend that combined cooking
surface rating does not exceed 55,000 BTU/hr.
The microwave oven is set for recirculation mode. For external
(wall or roof) venting, see "Venting Design Specifications"
section.
Special Requirements
For Wall Venting Installation Only:
Cutout must be free of any obstructions so that the vent fits
G
properly, and the damper blade opens freely and fully.
For Roof Venting Installation Only:
If you are using a rectangular to round transition piece,
3" (7.6 cm) clearance needs to exist above the microwave
oven so that the damper blade can open freely and fully. See
"Rectangular to Round Transition" illustration in "Venting
Design Specifications" section.
Dimension Requirements
For proper ventilation, the vent
screen must be free and clear of the
surrounding cabinetry. The maximum
allowable upper cabinet and side
cabinet depth (from rear wall to front
of cabinetry) must be no greater than
the depth of the microwave oven
metal outer wrapper (from back of
microwave oven to the vent screen).
NOTE: If the upper cabinet is deeper
than the maximum allowable depth
(see "Installation Dimensions" in this
section), then the installer must
space the microwave oven forward
so that the vent screen is free and
clear of any surrounding cabinetry.
