Find a suitable place to put your refrigerator. The fridge should be located away from any heat sources and have a water line, along with access to an electrical outlet.
Cut two long strips of cardboard, about 6-inches wide.
Tilt the refrigerator to the right, just an inch off the ground, and slide one of the cardboard pieces under the left side of the bottom of the fridge. Then repeat the process for the other side. Make sure enough of the cardboard is sticking out of the front of the refrigerator, so you can pull on it later to remove the cardboard. Ensure that every section of the refrigerator that touches the ground has cardboard under it.
Move the fridge directly in front of the wall or opening where you will put it. If your fridge has a water line, attach it to the water intake, normally located at the bottom of the back of the fridge. Tighten the water connection with your wrench. Then plug the fridge into an outlet.
Push the refrigerator to slide it over your floor and into place against the wall. Lean against the fridge while you pull out the cardboard strips to remove them. Finally, pull the fridge out enough so there is a 1/2-inch gap between the back plate and the wall.
Place your level on the top of the refrigerator to see if it is level. If it is not, have someone push back on the top of the fridge, enough to lift the front feet off of the floor. Turn the feet with your wrench to adjust the height. Some refrigerator models may need to have a toe grill or bottom cover removed to access the screws for the feet.
