Manitowoc Foodservice developed this manual as a

reference guide for the service agent and installer of

fountain equipment.

Fountain dispensing is the serving of a beverage (soft

drink, tea, or juice, etc.) from a dispenser that will chill

the product to an acceptable serving temperature for

the consumer.

The beverage, delivery system and dispenser can be

postmix or premix. The system may be an elaborate

system with most of the components in the back of the

store and the dispenser in the front. Fountain systems

could be a simple system with the complete system

under the counter where the dispenser is located.

Our goal is that this manual will remove some of the

confusion, and mystery of beverage dispensing

equipment while providing a general overview of

service to the equipment.

Dispensing Basics

WHAT IS CARBONATION

Carbonation is the process of mixing carbon dioxide

gas into a liquid (water). The resulting liquid is called

soda water or carbonated water. The carbon dioxide

gas is the bubbles you see when a carbonated

beverage (like soda) is dispensed.

Most cola, lemon-lime products, etc. are carbonated.

Normally teas, juices, etc. are noncarbonated.

Some beverage technicians refer to noncarbonated

water as sweet water.

WATER CHARACTERISTICS

Water makes up over 80% of the typical finished

beverage. The quality of this primary ingredient is of

utmost importance. You should use regular cold tap

water, not water that has been through a water

softener, conditioner, etc. Any off taste or color should

be treated by proper water filtration.
