1-9. GENERAL.

a. The walls, floor, and ceiling of the refrigerators are assembled from panels filled with densely packed insulating

foam, and covered with sheet metal. This provides an insulating barrier which helps maintain temperatures inside the

refrigerator.

b. A thermometer, mounted outside the refrigerator, displays the inside temperature.

c. The external power receptacle, mounted outside the refrigerators, is connected to a light switch, light and pilot

light. The light switch is mounted inside the refrigerator and controls the inside light. The pilot light is outside the

refrigerator and indicates when the inside light is on. This circuit requires a 125 VAC input to power the lights. (See
