2. Setup and Installation

Unpacking

Remove all packaging materials from inside and outside the microwave oven. Inspect the oven for any damage, such as a misaligned or bent door, damaged door seals and sealing surfaces, broken or loose door hinges and latches, or dents inside the cavity or on the door. If any damage is present, do not operate the oven and contact your dealer or qualified service personnel.

Placement

Place the microwave oven on a flat, stable surface that can support its weight and the heaviest food item likely to be cooked in it. Ensure there is adequate space for ventilation: at least 4 inches (10 cm) of clearance on the top, sides, and rear of the oven. Do not block any ventilation openings. Keep the oven away from heat sources, steam, or splashing liquids.

Cleaning the Interior

• Wipe the interior cavity after each use with a damp cloth to prevent food splatters from drying and hardening.
• For stubborn stains, place a cup of water with lemon slices in the oven and heat for 2-3 minutes until steam forms. This will loosen food particles, making them easier to wipe away.
• Do not use abrasive cleaners, steel wool, or harsh chemicals on the interior surfaces.

Cleaning the Exterior

• Wipe the exterior surfaces with a soft, damp cloth.
• For stainless steel surfaces, use a specialized stainless steel cleaner and polish in the direction of the grain.
• Clean the control panel gently with a damp cloth. Avoid excessive moisture.

Turntable Care

• The glass turntable and roller ring can be removed for cleaning. Wash them in warm, soapy water or in the dishwasher.
• Ensure the turntable and roller ring are completely dry before placing them back in the oven.
