If you are replacing an existing over the range microwave then the installation is reasonably easy and can be done by most people. You should have someone help to lift the microwave into position. The user/installation manual comes with step by step directions on how to install the microwave and all the necessary mounting hardware is included.
If you have never had an over the range microwave installed you will need to check to see if there is an electrical outlet in the cabinet above where you are installing it. If there is no electrical outlet you will need to have an electrician install the outlet for you.

The required clearance between the top of an electric stove and the bottom of this unit is 15". I hope this helps.
