• Beverage fountains comprise a number of moving and non-moving parts. These fountains get a lot of use -- in restaurants, schools, hospital dining rooms and workplaces -- and parts can wear out or become damaged, requiring replacement.
  
  

Pump, Carbinator & Dispenser

• A beverage fountain's pump brings the beverage to the dispenser. The pump can be continuous, with an "On/Off" switch, according to Instawares. Other fountains are activated when a user pushes his cup against a lever, such as typical restaurant beverage fountains. This lever or tab activates the pump, which sends water and CO2 to the carbinator, where both substances are combined, according to Discovery Channel. The carbinator sends the pressurized, carbonated water to the tab where it mixes with the flavored soda syrup.
  
  

Cooling System Parts

• This system cools the fountain beverages using a compressor, condenser, evaporator and fan, according to Drinking Fountain Doctor. The coolness of the beverage is controlled by a thermostat, which can be adjusted using a screwdriver.
  
  

Ice Maker & Container

• Some beverage dispensers have ice makers or containers to cool the drinks and allow customers to dispense ice cubes, according to Soda Fountain Faucets and Parts. If the beverage lacks an automatic ice maker, ice is manually added to the container by removing the top cover and pouring it in.
  
  

Tiered Tray Parts

• Another kind of beverage fountain uses a series of tiered trays stacked on top of each other, with each tray larger than the one above it. These trays are designed to fill with the beverage and spill over the top of each tray into the tray beneath, creating an attractive waterfall effect, according to Instawares. The tray is similar to the basin in a more conventional fountain, in which water collects and drains, according to Drinking Fountain Doctor.
  
  

Lighting & Branding Sign Parts

• Beverage fountains are often equipped with lighting to help customers judge how much soda or other beverage to dispense, according to Instawares. Lighting also makes the machine attractive to customers and can build sales. Soda fountain dispensers often feature small, plastic lighted signs above them where brand logos are affixed.
