1. ADJUSTABLE TEMPERATURE CONTROL
(1) Temperature control of freezer
Thermostat (senses freezer temperature) operates on ON/OFF switchover to control the compressor and
cool air circulating fan (F-fan motor) , and allows the freezer temperature to keep at a suitable temperature.
However adjust the freezer temp. control knob as follows depending upon the storing condition of foods.

(2) Temperature control of refrigerator
Damper-thermostat senses temperature of the refrigerator and changes the opening angle of the damper
automatically.
However, as the Damper-thermostat has no function to switch on or off the compressor and F-fan motor,
the freezer temperature control causes temperature in the refrigerator to vary to some extent.
However, adjust the refrigerator temp. control knob as follows depending upon the cooling condition.

REFRIGERATOR TEMP. CONTROL
Figure F-2.
When the temperature of the refrigerator is higher, R-fan thermo. senses the temperature and the
refrigerator is cooled efficiently by running of R-fan motor.
R-fan thermo. heater energizes when the door is opened intend to promote to running of R-fan motor.
NOTE: The refrigerator temperature is affected also by the freezer temperature. If the freezer temp. control
knob is set at the position "MAX", the temperature tends to be lower than the following values, and
if set at near the position "MIN", temperature tends to be higher.
If the refrigerator is operated for a long time with the freezer temperature control sets the "MAX"
position, foods stored in the refrigerator compartment may also freeze.
When refrigerator temperature control sets to the "MAX", some foods stored may freeze.
In this case adjust control set back to the "MED" position.
When refrigerator temperature control sets to the "MAX", some foods stored in fresh case may also
become frozen.

The values shown above refer to the measurement carried out center area and 1/3 of overall height from the bottom
at each of the refrigerator and the freezer after machine has been operated at an ambient temperature of 30˚C with no
food stored and the door closed until the temperature is stabilized.
The values vary depending upon frequency of opening and closing the door, ambient temperature, amount of stored
foods and manner of storing foods.
