REMARKS
6. SUPER FRZ. (Quick Freezing)
1) Comp. and F-fan are ON (about 150 minutes) regardless of F-sensor.
2) F-fan runs at 14V for the first 90 min., then at 12V for the rest time.

REMARKS
1. Temperature modes change by pushing the button.
2. R-fan are controlled by ON / OFF point of each mode.
3. Refrigerator Compartment [ON / OFF]
( Refreigerator Compartment middle OFF point : 0.7
( If RT
13
, R-S OFF point is 2
UP. Refrigerator Middle OFF
point : 2.7
)
4. Refrigerator Compartment [Low
5. Prevention of weak/poor-refrigeration
1) When weak refrigeration is sensed, comp. is ON regardless of F-sensor.
2) When R-sensor reaches R-fan OFF point, comp. is controlled by F-sensor and
R-fan turns OFF.
3) Sensing point of weak refrigeration : R-sensor OFF point of each mode + 7
4) Termination point : Same as R-sensor OFF point of each mode
