Electrical Requirements
If codes permit and a separate ground wire is used, it is
recommended that a qualied electrical installer determine that
the ground path and the wire gauge are in accordance with local
codes.
Check with a qualied electrical installer if you are not sure the
oven is properly grounded.
This oven must be connected to a grounded metal, permanent
wiring system.
Be sure that the electrical connection and wire size are adequate
and in conformance with the National Electrical Code, ANSI/
NFPA 70-latest edition or CSA Standards C22.1-94, Canadian
Electrical Code, Part 1 and C22.2 No. O-M91-latest edition, and
all local codes and ordinances.

Electrical Connection
A
To properly install your oven, you must determine the type of
electrical connection you will be using and follow the instructions
provided for it here.
■ Oven must be connected to the proper electrical voltage,
amperage and frequency as specied on the model/serial/
rating plate. See the following illustration.
A. Model/Serial/Rating Plate
■ Models rated from 7.3 to 9.6 kW at 240 V (5.4 to 7.4 kW at
208 V) require a separate 40 A circuit.
■ A circuit breaker is recommended.
■ Connect directly to the fused disconnect (or circuit breaker
box) through exible, armored or nonmetallic sheathed,
copper cable (with grounding wire). See “Make Electrical
Connection” section.
■ Flexible conduit from the oven should be connected directly
to the junction box.
■ Do not cut the conduit. The length of conduit provided is for
serviceability of the oven.
■ A UL listed or CSA approved conduit connector must be
provided.
■ If the house has aluminum wiring, follow the
procedure below:
Connect the aluminum wiring using special connectors
and/or tools designed and UL listed for joining copper to
aluminum.
Follow the electrical connector manufacturer’s
recommended procedure. Aluminum/copper connection
must conform with local codes and industry-accepted
wiring practices.

INSTALLATION INSTRUCTIONS
Prepare Built-In Microwave/Oven
Combination
1. Decide on the nal location for the oven. Locate existing
wiring to avoid drilling into or severing wiring during
installation.
WARNING
Excessive Weight Hazard
Use two or more people to move and install oven.
Failure to do so can result in back or other injury.
2. To avoid oor damage, set the oven onto cardboard prior
to installation. Do not use handle or any portion of the front
frame for lifting.
3. Remember to remove bottom vent from the foam packing on
top of oven.
4. Remove the shipping materials and tape from the oven.
5. Remove the hardware package from inside the bag
containing literature.
6. Remove and set aside racks and other parts from inside the
oven.
7. Move oven and cardboard close to the oven’s nal location.
2. Open the oven door.
3. Locate the oven door hinge locks in both corners of the oven
door, and then rotate the hinge locks toward the oven door
to the unlocked position. If the door hinge lock is not rotated
fully (see illustration B), the door will not remove properly.

A. Oven door hinge lock in
locked position
4. Partially close the door to engage the door latch locks. The
door will stop at this point.
B. Oven door hinge lock in
partially unlocked position

Remove Oven Door(s)
IMPORTANT: Use two hands to remove oven door.
1. Prior to removing the oven door, prepare a surface where
you will place it. This surface should be at and covered with
a soft blanket, or use the corner posts from your packaging
material.
4
5. Using two hands, grasp the edges of the oven door. Lift and
pull the oven door toward you and remove. You may need to
gently shift door from side to side as you pull.
6. Set the oven door(s) aside on the prepared covered work
surface, with the oven door resting on its handle.
7. To continue with the oven installation, go to the “Make
Electrical Connection” section.
Replace Oven Door(s)
IMPORTANT: Do not replace the oven door(s) until after the
oven has been installed into the cabinet.
1. Using two hands, grasp side edges of door at the midpoint.
Face the oven cavity.
2. Locate the slots on each side of the oven cavity for
the door hinge locks.
3. At a 45° angle, align door hinges with slots in the lower
front of the oven cavity. Slowly insert door, making
sure you maintain the 45° angle. You will know the
door is engaged in the slot when you feel a slight drop.
4. Lower the oven door to the fully open position. If the oven
door does not open to a full 90°, repeat steps 1 through 3.
5. Locate the oven door hinge locks in the corners of the oven
door, and rotate the hinge locks toward the oven cavity to
the locked position.
See Step 3 (illustration A) in the “Remove Oven Door(s)”
section for proper locked position.
A. Slot in the oven cavity for door hinge lock
A
6. Close the oven door.
7. When the hinges are properly installed and the door closed,
there should be an even gap between the door and the
control panel. If one side of the oven door is hanging lower
than the other, the hinge on that side is not properly installed.
