Seaga Quick Break Combo QB218 - Cleaning the Condenser

Cleaning the Condenser
Dust and dirt restricts good airow and cooling of the condenser, which will not allow the refrigeraon unit to
chill the beverages properly. Brush the dirt and dust from the condenser ns every thirty (30) days as roune
maintenance. You can also blow canned air (available at computer and oce supply stores) through the
condenser or vacuum clean it. Do not damage the ns of the condenser while cleaning. You should also clean
the grate located on the inside of the Front Door refrigeraon vents (see Figure 2).
Refrigeraon
Refrigeraon 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 selecons to the outside of the machine and dissipang 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 le of the machine and it is
where the heat is dissipated from the cooling process and blown to the outside of the machine. The evapora-
tor is located inside the machine towards the back of the cooling system underneath the beverage unit secon
being cooled. Its purpose is to absorb the heat from the drink selecons 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 pres-
sure and circulaon of the refrigeraon gas.
The refrigeraon system is monitored and controlled by several key electrical components. The condenser fan,
two evaporator fans, temperature sensor, VMC, and the start and overload components located on the side of
the compressor. The line voltage from the outlet in the room is fed to the three fans, the condenser fan and
the evaporator fans, and they run connuously as long as the machine is plugged into power coming from the
wall. The temperature sensor and VMC control the on and o cycling of the compressor. The temperature sen-
sor is located on the back side of the refrigeraon deck.
To determine if the compressor system is running it is somemes dicult due to the fact that the compressor
tends to be very quiet. The sound and slight vibraon from the fans running can somemes be mistaken for
the compressor running. One way to tell if the compressor system is running is to cauously 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 me, you can assume there is an electrical problem in the circuit-
ry or components that operate the compressor. Another way to see if the compressor is running is to feel the
air exing 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 obstrucons.
