INSTALLATIONS 

 

INSTALLING 

1. Empty the microwave oven and clean inside it with 

a soft, damp cloth. Check for damage such as 

misaligned door, damage around the door or dents 

inside the cavity or on the exterior. 

 

2. Put the oven on a counter, table, or shelf that is 

strong enough to hold the oven and the food and 

utensils you put in it. (The control panel side of the 

oven is the heavy side. Use care when handling.) 

 

3. Do not block the vent and the air intake openings. 

Blocking vent or air intake openings can cause 

damage to the oven and poor cooking results. 

Make sure the microwave oven legs are in place to 

ensure proper air flow. 

 

4. The oven should not be installed in any area where 

heat and steam are generated, because they may 

damage the electronic or mechanical parts of the 

unit. 

Do not install the oven next to a conventional 

surface unit or above a conventional wall oven. 

 

5. Use microwave oven in an ambient temperature 

less than 104°F(40°C). 

 

6. Place the microwave oven on a sturdy and flat 

surface at least 10 cm(4 inches) from the wall. 

 

7. Place the microwave oven as far away as possible 

from TV, RADIO, COMPUTER, etc., to prevent 

interference.
