IMPORTANT–Please Read and Follow! Please read all instructions thoroughly before installing the Over the Range Microwave. 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 Over The Range Microwave Hood is installed. See ELECTRICAL GROUNDING INSTRUCTIONS on page 2.



Unpacking and Examining

Your Oven

Open the bottom of the carton, bend the carton flaps back and tilt the oven over to rest on plastic foam pad. Lift carton off oven and remove all packing materials, Wall and Top Cabinet Template, Turntable, and Turntable Support. SAVE THE


Remove the feature sticker from the outside of the door, if there is one.

DO NOT REMOVE THE WAVEGUIDE COVER, which is located on the right side wall of the oven cavity. Check to see that there is a Wall TEMPLATE and Top CABINET Template. Read enclosures and SAVE the Use and Care manual.

Check the oven for any damage, such as misaligned or bent door, damaged door seals and sealing surfaces, broken or loose door hinges and latches and dents inside the cavity or on the door. If there is any damage, do not operate the oven and contact your dealer or Bertazzoni AUTHORIZED SERVICER.

Wall Construction

This over the range microwave 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" x 4" wood studding and 3/8" or more thick dry wall or plaster/lath. The mounting surfaces must be capable of supporting a weight of 110 pounds—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" x 4" wall stud.

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

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

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.

Mounting Space

This over the range microwave requires a mounting space on a wall as shown in Figure 1. It is designed to be used under standard 12" wall cabinets.

Electrical grounding instructions

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.

Electrical Requirements

The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE GROUNDING PIN FROM THE PLUG.

DO NOT USE AN EXTENSION CORD. If the power supply cord is too short, have a qualified electrician or serviceman install an outlet near the appliance.

The Power Supply Cord and plug must be connected to a separate 120 Volt AC, 60 Hz, 15 Amp, or more branch circuit, single grounded receptacle. The receptacle should be located inside the cabinet directly above the over the range microwave mounting location as shown in figure 2.


If you have any questions about the grounding or electrical instructions, consult a qualified electrician or serviceperson.


Model KO30 PRO X

Neither Bertazzoni nor the dealer can accept any liability for damage to the oven or personal injury resulting from failure to observe the correct electrical connection procedures.

Radio or TV Interference

Should there be any interference caused by the over the range microwave to your radio or TV, check that the oven is on a different electrical circuit, relocate the radio or TV as far away from the oven as feasible or check position and signal of receiving antenna.

Hood Exhaust Duct

Installation Hardware

When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal; absolutely do not use plastic duct. Check that all connections are made securely. Please read the following carefully:

Exhaust Connection: The hood exhaust has been designed to connect to a standard 3-1/4" x 10" 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 exhaust.

Maximum Duct Length: For satisfactory air movement, the total duct length of 3-1/4" x 10" rectangular or 6" diameter round duct should not exceed 140 feet.

Elbows, adapters, wall caps, roof caps, etc. 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 3 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.

The INSTALLATION HARDWARE items 1 - 5 are in a small bag. Items 6 - 9 are packed separately. All items are in a small carton packed below the oven.

Ventilation System

(Preparing Oven for Installation)

This over the range microwave is designed for adaptation to three types of hood ventilation systems. Select the type required for your installation.

Recirculating — non-vented, ductless.

Follow installation procedure (A). Recirculating requires the use of the Charcoal Filter, which has already been installed in the oven.

Horizontal Exhaust — outside ventilation. Follow installation procedure (B).

Vertical Exhaust — outside ventilation. Follow installation procedure (C).

A.Recirculating: Non-Vented, Ductless Operation

The unit is shipped assembled for recirculating.

The Exhaust Damper Assembly is not required for recirculating operation.

Oven Installation

This oven cannot be properly installed without referring to the mounting instructions found on wall and top cabinet templates.

The next step is to read and follow mounting information on wall and top cabinet templates. This oven must be attached to at least one wall stud. See WALL CONSTRUCTION.

When done with templates, proceed to mounting scale plate section.

Mounting Scale Plate

1.The Scale Plates are used to help locate the mounting plate. Attach 2 Scale Plates with tape (not included). See Figure 14 and WALL TEMPLATE for locations. After securing the mounting plate, remove and discard the Scale Plates.
