The conduit cable, where connected at the oven, swivels. Rotate conduit cable upward (or downward) and direct through hole prepared in cabinet to attach to junction box.
To maintain serviceability, the flex conduit must not be shortened and should be routed to permit temporary removal of the oven.
13
Before installing the combination oven, be sure to verify the cabinet dimensions and electrical connections.
Check that the cabinet opening is level and plumb for correct installation.
It is recommended to remove the traditional (lower) oven door to help reduce the unit weight and provide easier access to the latch levers located inside the oven. Do not remove microwave, speed oven or steam convection oven doors.
The oven door is heavy and fragile. Use both hands to remove the oven door. The door front is glass. Handle carefully to avoid breaking.
Grasp only the sides of the oven door. Do not grasp the handle as it may swing in your hand and cause damage or injury.
Failure to grasp the oven door firmly and properly could result in personal injury or product damage.
To avoid injury from hinge bracket snapping closed, be sure that both latch levers are securely in place before removing the door. Also, do not force door open or closed--the hinge could be damaged and injury could result.
Do not lay removed door on sharp or pointed objects as this could break the glass. Lay door on a protected flat, smooth surface, positioned so that the door cannot fall over.
Be sure to read all warnings and cautions in the installation manual regarding the door removal before attempting to remove the door.
Open the door completely.
Flip latch levers on hinges all the way down toward you.
Holding the door firmly on both sides and using both hands, close the door gently until it stops against the latch levers, about 30 degrees from the closed position.
Carefully lift the door up and out of the hinge slots. Hold firmly; the door is heavy.
Place the door in a convenient and stable location until you are ready to reinstall it. Lay the door on a towel or section of protective foam padding to avoid damage to the door or the floor.
14
It is recommended to wear gloves and long sleeves to protect hands and forearms from abrasion and potential scratches during the lifting process. It is also recommended to take off watches and jewelry and to wear work shoes during installation for foot protection.
Three people or proper equipment are needed to safely lift the combination oven into the cabinet opening.
There is a ridge across the top front of the lower oven cavity. Lift by grasping this ridge with one hand while placing the other hand on the back of the unit (for helpers lifting from the sides of the unit). If a third helper is lifting from the front, both hands should lift by holding this ridge area.
Lift points or gripping points (2) on the back of the unit shows the location of the opposite hand for the helpers lifting from the sides of the unit. Adjust the location as needed to facilitate the lift.
Wear gloves, a long sleeved shirt, and avoid sharp edges to reduce the risk of cuts or abrasions to the arms or hands.
Lift locations or gripping points (with lower oven door removed).
Lift points or gripping points (1) on the front of the unit are for lifting from the sides of the unit. Lift point (3) on the front of the unit is for a third person to help lift the unit.
15
Placing Combination Oven Into Cabinet
Opening
To avoid damage to the door, do not lift, pull or push the unit during installation by using any oven door handle as a gripping point.
When lifting the combined unit into place, avoid grasping the upper element to avoid damaging it. See the illustration below for the correct lifting point. This illustration shows a detailed view of the oven cavity. Note the location of the ridge inside the top of the cavity. This is the area to grip from the front when lifting the combined unit.
Note: Be careful not to crimp the flexible conduit between the oven and the cabinet back wall. If necessary, guide the flexible conduit into the wall of cabinet access hole so it doesn’t prevent the unit from being pushed all the way into the cabinet opening. The oven should be straight and level.
Hold the door firmly in both hands.
Hold the door at an 30° angle from the closed position (approximately 7 inches open at the top).
Insert the hinges into the slots.
You may need to rock the door forward and backward slightly to seat the hinge feet. The door should lower about 3/4” and stop. If not, the hinges have not engaged properly and the door could fall if it is released. The door may need to be removed and re-inserted until the hinges sit correctly in the slots.
Open door all the way to expose hinges, latch levers and slots.
Push latch levers up until they are locked into the slots, flush with front of the oven body.
Close and open door slowly to be sure it is correctly and securely in place. Door must be straight.
See the Use and Care Manual for each unit of the combination oven for troubleshooting information. Refer to the Statement of Limited Warranty in the Use and Care Manuals.
