CLEANING THE CONDENSER
Dust and dirt restricts good airflow and cooling of the condenser, causing the refrigeration unit to not chill
the beverages properly. Remove the front bottom panel of the beverage unit. Brush the dirt and dust from
the condenser fins. You can also blow canned air, available at computer and office supply stores, on the
condenser or vacuum clean it. Do not damage the fins of the condenser while cleaning. Reassemble the
front bottom panel after cleaning.
REFRIGERATION
Refrigeration is the transfer of heat from one area to another. In the case of this machine we are transferring
the heat from the area containing the beverage selections to the outside of the machine and dissipating the
heat throughout the room. The more heat we are able to transfer away from the beverages the colder they
become.
This process is accomplished by the use of a sealed compressing system using an ozone friendly gas
commonly known as R134a refrigerant. The system is comprised of several key mechanical components:
the condenser, the evaporator and the compressor. The condenser is located in the lower front left of the
machine and it is where the heat is dissipated from the cooling process and blown to the outside of the
machine. The evaporator is located inside the machine towards the back of the cooling system underneath
the beverage unit section being cooled. Its purpose is to absorb the heat from the drink selections and
provide the cool air needed to refrigerate the beverages. The compressor is the heart of the cooling system
and its purpose is to provide pressure and circulation of the refrigeration gas.
The refrigeration system is monitored and controlled by several key electrical components: the condenser
fan, evaporator fan, temperature sensor, VMC, and the start and overload components located on the side
of the compressor. The line voltage from the 115 volt AC outlet in the room is fed to the two fans, the
condenser and the evaporator fans, and they run continuously as long as the machine is plugged into 115
volt AC power coming from the wall. The temperature sensor and VMC control the on and off cycling of the
compressor. The temperature sensor is located on the back side of the refrigeration deck.
To determine if the compressor system is running it is sometimes difficult due to the fact that the compressor
tends to be very quiet. The sound and slight vibration from the fans running can sometimes be mistaken
for the compressor running. One way to tell if the compressor system is running is to cautiously place your
hand on the compressor to feel if it is warm. CAUTION as it may be hot to the touch. If the compressor is
stone cold and stays that way for an extended period of time, you can assume there is an electrical problem
in the circuitry or components that operate the compressor. Another way to see if the compressor is running
is to feel the air exiting the condenser coils from the front to see if there is any heat.
Any problems with the fans running can also lead to a cooling system failure. In order for any cooling system
to operate properly it is most important that all fans are running and that the condenser coil is kept clean
and free of any dust, dirt or obstructions.
