OPERATING INSTRUCTIONS & INSTALLATION

=> ICE-MAKER stops operation if function of ICE OFF has been selected. After if cubic / crushed are selected, then water is supplied. If cubic / crushed are selected, now you can be promptly provided with ice only that was already formed before selecting ice off.

1-7) When drawing out ice, this is extracted after DISPENSER SWITCH is depressed and ICE COVER is completely opened.

1-8) ICE COVER is shut after 5 seconds from time point when DISPENSER SWITCH turned off after drawing out ice.

1-9) If DISPENSER SWITCH turned ON or WATER SWITCH turned ON, DISPENSER LAMP is lighted but turns off after 5 seconds from time point when DISPENSER SWITCH and WATER SWITCH would have turned OFF.

Caution : because if ice cover is coercively closed then it may be damaged, please draw out ice once again if ice cover would not be closed, so that the cover operate rationally.

Note) When drawing out ice after selecting the ice stop, only the ice remaining in ice tray may be drawn out. And even when ice stop has been selected, cubic / crushed may be used restricted to the remaining ice.

2)Water Dispenser Function

2-1) As this function is type of direct connection to water, it works so that water is extracted by opening of water solenoid valve installed at right side of machine compartment if water lever is depressed. If abnormality occurred in water dispenser function, repair it by checking solenoid itself, connection tube, water supply status etc.

3-6) Light Operation

6-1) This function is selected or canceled by light selection button.

6-2) If the light button is selected under light cancellation status, the LIGHT LED and the DISPENSER LIGHT turn on.

6-3) If the WATER SWITCH or the DISPENSER SWITCH is turned on, under the condition of light cancellation status, the DISPENSER LIGHT turns on.

6-4) Under the condition of light function selection, the LIGHT LED and the DISPENSER LIGHT are always turned on regardless of WATER SWITCH and DISPENSER SWITCH operation conditions.

3-7) Machine Room F-Fan Motor Delay Function

The temperature in this refrigerator is automatically controlled by program depending on ambient temperature. Among the operative functions depending on ambient temperature, the compressor cooling fan (machine room fan) is controlled as shown in the table below. Accordingly, in case that cooling fan may revolve with delay or may not revolve at all according to conditions when operating the compressor, please be acquainted with details and refer to them during service.
