2. REFRIGERATION CYCLE
Mechanical refrigeration is accomplished by continuously circulating, evaporating, and con-
densing a fixed supply of refrigerant in a closed system. Evaporation occurs at alow tempe-
rature and pressure while condensation occurs at high temperature and pressure. Thus it is
possible to transfer heat fom an area of low temperature(i.e., refrigerated compartment) to
an area of high temperature(i.e., surrounding of refrigerator).
CONDENSER
COMPRSSORCAPILLARY TUBE
EVAPORATOR
THE BASE REFIGERATION CYCLE
Beginning the cycle at the evaporator inlet the low pressure liquid expands, absorbs heat
(so refrigerator inner-cabinet is cooled), and evaporates, changing to alow pressure gas
at the evaporator outlet.
The compressor pumps this gas from the evaporator, increases its pressure, and discharges
the high pressured- temperature gas to the conenser.
The condenser lets high pressured- temperature gas emit the heat(so surrounding of the
condenser is warmed) in order to make it condense.
The capillary tube prevents high pressured- temperature gas from entering the evaporator
in order to lower the pressure in the evaporator and control the flow of refrigerant into the
evaporator automatically.
Eventually the desired air temperature in regrigerator inner-cabinet is reached, the thermostat
(temperature controller) will break the electrical circuit to the compressor motor and stop
the compressor.
-6 -
As the temperature of the air rises, the thermostat(or controller) remakes the electrical circuit.
The compressor starts, and cycle continues.
The schematic refrigeration(or freezing) cycle of BASF1/BASF2/BASF3/BASR1/BASR2
BASR3/BAGR72 is like below.

1. OPERATION FOR BASF1, BASF2, BASF3 MODELS
1) BASIC OPERATION
① Plug in the power cord and turn on the power switch located on the bottom of the top grille
right side.
[ The unit should be plugged into a 115V±10%, 60Hz (BASF1, BASF2 models) ]
[ The unit should be plugged into a 115V/208~230V, 60Hz (BASF3 model) ]
② Display panel will be lightened for 2 seconds with buzzer then displays cabinet interior
temperature (T-sensor) and running conditions.
If cabinet interior temperature is higher than 14℉(BASF1, BASF2, BASF3 models), compressor
will run without delay, and lower than 14℉(BASF1, BASF2, BASF3 models), compressor will
run after 3 minutes.
③ The default OPERATING TEMPERATURE SETTING
BASF1, BASF2, BASF3 : Temperature set point (setting mode sign [st]) is –9℉
Temperature differential set point (setting mode sign [di]) is 10℉.
(Operating Temperature : -14℉ ~ -4℉)
Range of adjustable set point: -22℉ ~ 8℉
④ Dfrost frequency is controlled by MICOM and the default defrost frequency is 6 hours.
⑤ The light inside the cabinet comes on when the door is opened.
The cabinet interior cooling fan has 3 seconds delay when the door is closed.
⑥ If door is opened, door open warnign sign (LED) will turn on.
If door is opened more than 30 seconds, the sound alarm beeps 3times,
if open more than 60 seconds, the sound alarm beeps 5 times and if open more than 5 minutes,
the sound alarm will beep continuously.
⑦ If cabinet interior temperature is higher than 14℉(BASF1, BASF2, BASF3), the panel
displays [Hi] and lower than -50℉(BASF1, BASF2, BASF3), the panel displays [Lo].
