FUNCTIONS
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.

PURPOSE
For making ice rapidly or fast freezing.
For storing frozen food for a short period (up to one month).
When frozen food or ice cream is not stored.
For normal freezing.

When restocking with fresh food.

REFRIGERATOR TEMP. CONTROL
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.

The values shown above refer to the case where the
freezer temp. control knob is set at "MED".
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 "CHILLED ZONE", some foods stored may
freeze.
In this case adjust control set back to the "MED" position.
When refrigerator temperature control sets to the "CHILLED ZONE", some foods stored in chilled
case may also become frozen.

(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.
