Please read all instructions thoroughly before

installing the Over The Range Microwave Oven.

Two people are recommended to install this

product.

If a new electrical outlet is required this must be

completed by a qualiﬁed electrician before the

Over-the-range microwave oven is installed. See

ELECTRICAL GROUNDING INSTRUCTIONS.

This oven requires a mounting space on a wall as

shown in Figure 1.

For proper installation and servicing, a 2 in/

51 mm space is necessary between the top of

the range backsplash and the bottom of the oven.

WALL CONSTRUCTION2

This Over-the-range microwave oven should be

mounted against and supported 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 in x

4 in (51 mm x 102 mm) wood studding and 3⁄8in

(10 mm) or more thick dry wall or plaster/lath. The

mounting surfaces must be capable of supporting

weight of 110 lb (50 kg)—the oven and contents

and the weight of all items which would normally

be stored in the top cabinet above the unit.

The unit should be attached to a minimum of one

2 in x 4 in (51 mm x 102 mm) wall stud.

To ﬁnd the location of the studs, one of the follow-

ing 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 in (406.4 mm) or 24 in (610 mm)

to either side of this mark.

If the unit is unable to be supported by a stud,

toggle bolts and top cabinet screws will need to

be placed, see details in the WALL TEMPLATE.

The top cabinet should be tested to ensure it is

securely attached to the wall. Place extra weight

up to 110 lb (50 kg) inside the top cabinet to test

the support.

This appliance must be grounded. This oven is

equipped with a cord having a grounding wire with

a grounding plug. It must be plugged into a wall

receptacle that is properly installed and grounded

in accordance with the National Electrical Code

and local codes and ordinances. In the event of

an electrical short circuit, grounding reduces risk

of electric shock by providing an escape wire for

the electric current.

WARNING - Improper use of the grounding plug

can result in a risk of electric shock.

The oven is equipped with a 3-prong grounding

plug. DO NOT UNDER ANY CIRCUMSTANC-

ES CUT OR REMOVE THE GROUNDING PIN

FROM THE PLUG.

The Power Supply Cord and plug must be

connected to a dedicated 120 Volt AC, 60 Hz,

15 Amp, or branch circuit, single grounded

receptacle. The receptacle should be located

inside the cabinet directly above the Over the

range microwave oven mounting location.

NOTE:

1. If you have any questions about the grounding

or electrical instructions, consult a qualiﬁed

electrician or serviceperson.

2. No liability can be accepted for damage to the

oven or personal injury resulting from failure to

observe the correct electrical connection pro-

cedures.

HOOD EXHAUST DUCT4

When the hood is vented to the outside, a hood

exhaust duct is required. All ductwork must be

metal; do not use plastic duct. Check that all con-

nections are secure. Please read the following

carefully:

Exhaust connection

The hood exhaust has been designed to connect

to a standard 3 1⁄4in x 10 in (82.5 mm x 254 mm)

rectangular duct. If round duct is required, a rect-

angular-to-round adapter must be used.

Rear exhaust

If a rear or horizontal exhaust is to be used,

care should be taken to align the exhaust with

the space between the studs, or wall should be

prepared at the time it is constructed by leaving

enough space between wall studs to accommo-

date the exhaust.

Maximum duct length

For satisfactory air movement, the total duct

length of 3

1⁄4in x 10 in (82.5 mm x 254 mm)

rectangular or 6 in (152 mm) diameter round duct

should not exceed 140 feet (42.67 meters).

Elbows, adapters, wall and roof caps. present ad-

ditional resistance to air ﬂow and are equivalent

to a section of straight duct which is longer than

their actual physical size. When calculating the

total length, add the equivalent lengths of all tran-

sitions and adapters plus the length of all straight

duct sections. Figure 4 shows the approximate

feet of equivalent length of some typical ductwork

parts.

Use the values in parentheses for calculating air

ﬂow resistance equivalent, which should total

less than 140 feet (42.67 meters).
