PRECAUTIONS FOR USING LEAD-FREE SOLDER3.

1) Employing lead-free solder

The PWB of this model employs lead-free solder. This is indicated by the "LF" symbol printed on the PWB and in the service manual. The sufﬁ x letter indicates the alloy type of the solder.

Example:

Indicates lead-free solder of tin, silver and copper

2) Using lead-free wire solder

When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may result in cold soldered joints and damage to printed patterns.)

As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommend that a dedicated bit is used, and that the iron temperature is adjusted accordingly.

3) Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability, (ﬂ ow), to prevent damage to the land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time. Remove the bit as soon as a good ﬂ ow is achieved.The high content of tin in lead free solder will cause premature corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.

Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their characteristics, making good soldering more difﬁ cult. It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be taken to clean the bit thoroughly after each use.

Speciﬁ cations of Refrigerant Valve Operation3-4.

Modes and operating conditions of refrigerant valve (3-way valve)1)

Valve is fully closed:1.

• This mode is used in compressor OFF status.

Only fine capillary is opened:2.

• During normal cooling operation

Only wide capillary is opened:3.

• During cooling operation under large load

Both capillaries are opened4.

• The refrigerator is set in this mode for only one minute after the power supply is turned ON. This mode is used for vacuuming. During cooling operation, this mode is not used.

• Differentiation between ﬁ ne capillary and wide capillary

- Fine capillary: Capillary tube A

- Wide capillary: Capillary tube B

- The ﬁ ne capillary is identiﬁ ed with a yellow mark.

Fault and status of refrigerant valve2)

• There is no method to give an instruction from the PWB and conﬁ rm the valve position.

Refrigerant valve status Problem

1

Both capillaries are opened, and the valve does not operate. No problem on cooling operation

No problem

2

Only the ﬁ ne capillary is opened, and the valve does not operate. Cooling performance deteriorates under large load.

Refrigerant shortage may occur, causing frost around the evaporator inlet to increase.

3

Only the wide capillary is opened, and the valve does not operate. No problem on cooling operation

No problem

4

Both capillaries are closed, and the valve does not operate. Cooling operation is disabled.

Cooling operation is disabled even when the

compressor is ON.

• Fault of the refrigerant valve cannot be displayed in the self-diagnosis mode.

Operation in the self-diagnosis mode2)

The compressor is forcedly turned ON. (Excepting a period of defrosting operation and compressor ON delay •

time)

The cooling, condenser and R-fan motors are forcedly turned ON.•

(These motors will be forcedly turned ON even while the compressor is OFF. However, when the door is opened, the motors other than the condenser fan motor are kept OFF.)

The refrigerator compartment/vegetable compartment PCI fan and the PCI are forcedly turned ON. (However, •

when the door is opened, the PCI and fan are kept OFF.)

When the refrigerator compartment door is opened, the R damper is forcedly closed. When the refrigerator • compartment door is closed, the R damper is forcedly opened. (Opening/closing the refrigerator compartment door activates the R damper operation.)

During execution of the self-diagnosis mode, and for 20 minutes after cancellation of this mode, self-diagnosis • data serial output is executed.

During execution of the self-diagnosis mode, and for 20 minutes after cancellation of this mode, the door-open • buzzer does not sound.
