SAFETY AND PRECAUTION

1) For starters, be sure to check any chances of the leakage of electricity

2) You could handle a part in the vicinity of electricity after unplugging

3) You should put on rubber glovers to prevent an electric shock on operation test

4) Make sure the rated current, voltage, capacity before using an instrument

5) Keep your wet hands away from the metal goods in the freezer compartment not to be frostbitten

6) Be careful not to let water to permeate the electric part in the machine room

OPERATION AND FUNCTIONS

5. SILENT (Silence Mode)

INPUT Control Object

1. COMP

1. CDS SENSOR

1. Purpose of Silence mode To reduce refrigerator noise at night by decresing fan RPM to a minimum degree

2. Condition to start

The optical or light sensor in top middle of control panel senses surround light

and Silence mode starts if the amount of light sensed is below the standard value

for

more than 1 minute.

(The mode does not start for initial 240 minutes to prevent down of cooling

performance.)

- Standard value to decide "night" : below 5~7 Lux (optical sensor surface)

- Standard value to decide "daytime" : above 4~16 Lux (optical sensor surface)

CONTENTS REMARKS

Control of Silence mode : operation mode when the optical sensor feels that it is

night

Normal control : daytime operation mode

(Refrigerator noise is relatively low at daytime.)

Load control : operation mode when inside temperature goes up due to an

increase of load (foods) or frequent door openings.

OPERATION AND FUNCTIONS

CONTENTS REMARKS

1. Fan voltage of each control mode

2. Control against (under) load (Load Control)

1) Purpose : To restore F/R-temperature which has risen by load (much foods in or frequent door openings) as soon as possible

2) Display : "SPEED" lights until the mode and speed icons flicker.

3) Conditions to start (from both Normal and Silence) F or R door open time exceeds 30 secon ds at a time Freezer and Refrigerator

load control starts respectively . Over [F-sensor On Point + 5 degree] F load control Over [R-sensor On Point + 5 degree] R load control

4) Conditions to avoid load control Initial operation (right after power input, Just after Pre-cool, Heater defrosting,

Pause, Defrosting cycle.)

(After door opening, the load control enters if the condition complies with.) (During Sleep Mode1, load control isn t active.)

5) Control Method 5-1) Control mode by F/R-door open time (over 30 seconds) F/R-fan works by 14V respectively. 5-2) Control mode by [F-sensor On Point + 5 degree]

F-fan works by 14V.

5-3) Control mode by [R-sensor On Point + 5 degree]

R-fan works by 14V.

C-fan works by 10V as normal.

6) Conditions to stop

The mode works for 20 minutes.

(If another condition happens at the end of the mode, it starts again.)

When it reaches to [F-sensor Off point], F-fan load control mode stops. When it reaches to [R-sensor Off point], R-fan load control mode stops.
