2 WALL CONSTRUCTION

This Microwave Oven/Hood should be mounted against and sup-
ported by a flat vertical wall. The wall must be flat for proper
installation. If the wall is not flat, use spacers to fill in the gaps.
Wall construction should be a minimum of 2" x 4" wood studding
and

" or more thick dry wall or plaster/lath. The mounting sur-

faces must be capable of supporting weight of 110 pounds—the
oven and contents—AND the weight of all items which would nor-
mally be stored in the top cabinet above the unit.

The unit should be attached to a minimum of one 2" x 4" wall stud.

To find the location of the studs, one of the following methods may
be used:

A. Use a stud finder, a magnetic device which locates the nails in

the stud.

B. Use a hammer to tap lightly across the mounting surface to find

a solid sound. This will indicate stud location. 

The center of the stud can be located by probing the wall with a
small nail to find the edges of the stud and then placing a mark
halfway between the edges. The center of any adjacent studs will
normally be 16" or 24" to either side of this mark.

NOTE: In the event that the unit will be unable to be supported by any stud, it will be necessary to use spe-
cial care in the placement of the toggle bolts and top cabinet screws. See Wall Template for details. The top
cabinet should be tested to ensure it is securely attached to the wall. Place extra weight up to 110 pounds
inside the top cabinet to test the support.

NSTALLATION INSTRUCTIONS

Please read all instructions thoroughly before installing the Microwave Oven/Hood System. Two people are
recommended to install this product.

If a new electrical outlet is required, its installation should be completed by a qualified electrician before the
Microwave Oven/Hood is installed. See 3 ELECTRICAL GROUNDING INSTRUCTIONS on page 2.

1 MOUNTING SPACE

This Microwave Oven/Hood requires a mounting space on a wall
as shown in Figure 1.   

If the space between the wall cabinets is greater than 30-inches
(36-inches or 42-inches), a Filler Panel Kit may be used to fill the
gap between the Microwave Oven/Hood system and wall cabi-
nets. The Filler Panel Kit is sold as an optional accessory; each
kit contains two 3-inch panels. The Filler Panel Kit should be
installed before the Microwave Oven/Hood is installed.

For proper installation and servicing, a 2-inch space is necessary
between the top of the range backsplash and the bottom of the
Microwave Oven/Hood system.
