MOUNTING SPACE WALL CONSTRUCTION

or more from ﬂoor

Max. 13" (330.2 mm)

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 Over-the-range microwave 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 Over-the-range microwave oven.

Min. 12" (304.8 mm)

Min. 30"

At least 2" (50.8 mm)

Backsplash

30" (762 mm) or more from cookingsurface

66" (1676.4 mm)

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

⁄8 in (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 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 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.

ELECTRICAL GROUNDING INSTRUCTIONS HOOD EXHAUST DUCT

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 CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG.

The Power Supply Cord and plug must be connected to a separate 120 Volt AC, 60 Hz,

13.5 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 procedures.

Ground

Receptacle

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 connections are secure. Please read the following carefully:

Exhaust connection

The hood exhaust has been designed to connect to a standard 3 1⁄4 in x 10 in (82.5 mm x 254 mm) rectangular duct. If round duct is required, a rectangular-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 accommodate the exhaust.

Maximum duct length

For satisfactory air movement, the total duct length of 3 1⁄4 in 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 additional 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 transitions 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).
