This service manual handbook can be owned but can not be reproduced without permission from Refrigerator Business Unit, PT Panasonic Manufacturing Indonesia.

There are special components used in this equipment which are important for safety. These parts are marked by in the Exploded Views and Replacement Parts List. It is

essential that these critical parts should be replaced with manufacturer's specified parts to prevent shock, fire or other hazards. Do not modify the original design without permission

of manufacturer.

CFC & HCFC have been used in refrigerant as refrigerator and the insulation materials for many years. But it is now known that these compounds which once

seemed so ideal for use as cleaning agents and in refrigeration systems, destroy the earth's ozone layer as a result, an international body decided on a total

worldwide ban of harmful CFCs by the end of 1995.

This service information is designed for experienced repair technicians only and is not designed for use by the general public. It does not contain warnings or

cautions to advise non-technical individuals of potential dangers in attempting to service a product. Products powered by electricity should be serviced or repaired

only by experienced professional technicians. Any attempt to service or repair the product or products dealt with in this service information by anyone else could

result in serious injury or death.

6. Reparation Standard

6.1. REPAIRING DEVICES WHICH ARE EXCLUSIVE - USE FOR HFC-134a REFRIGERANT

Important Notice :

1. Use repairing devices which are exclusive-use for HFC-134a refrigerating unit.

When pipe cleaning is so need :

When pipe cleaning is required :

3. Never use blowing agent containing chlorine.

CFC-12, CFC-113, HCFC-22, HCFC-141b, R-502

4. Be sure to use dryer which is exclusive - use HFC-134a.

Otherwise refrigerant HFC-134a will chemically decompose.

6.2. REPAIRING STANDARD OF REFRIGERATING UNIT HFC-134a

1. OMust be done

D Need to be done if compressor oil get dirty and no good quality (color changing)

Noise up normal

Motor burning

This refrigerator use compressor with Freol Oil. Freol Oil employed as new compressor oil for

refrigerant HFC-134a.

Freol oil is characteristic of higher hyroscopicity. When moisture leaks into the refrigerating

unit, it will chemically react with the moisture and solid substance clogging the pipe will form

It is also characteristic of less stability when chlorine is contain. Freol Oil will chemically

react with refrigerants containing chlorine and solid substance clogging the piping will form.

From the time just after pipe cleaning is completed until the process of setting compressor and

dryer (just before vacuum pumping process).

Since refrigerant HFC-134a has higher degree of swelling to the resin, charge hose and

packing should be made from good materials. Therefor when HFC-134a refrigerating unit,

repairing method and repairing devices axcept for vacuum pump are different from

conventional method and devices. This is to avoid mixture of different refrigerants and mixture

of different oil.

Do not keep the pipe open to air more than 30 minutes. Rubber caps of compressor parts

should be removed just before installation. It should be finished within 30 minutes.

From the process of removing compressor until the process of setting compressor and dryer

(just before vacuum pumping process).

Caution :

6.3. TOOL FOR REPAIRING REFRIGERATING UNIT HFC-134a

When the fitting for using CFC-12 is connected with the charge pipe (yellow), and then turn the

switch to be using CFC-12, the adaptor can be used for vacuum pumping of CFC-12

refrigerating unit.

Be sure to connect the adaptor with vacuum pump, so that it can be used for both CFC-12 and

HFC-134a.

Since the inside of manifold gauge and charge hoses are vacuum state after vacuum pumping,

the oil of vacuum pumping may flow into HFC-134a refrigerant unit. The adaptor prevents the oil

flowing into the refrigerating unit.

Before running the vacuum pump, connect the charge pipe (yellow) with the fitting for using

HFC-

1354a, and then turn the switch to be using HFC-134a.

Conventional repairing devices for CFC-12 can not connect with repairing devices for HFC-

134a. Because of the shape of fitting for HFC-134A (M10 x P1.5 mm) is different from

conventional ones.

STANDARD PROCEDURE

Diagnosing the trouble

Discharging the refrigerant

Removing the Compressor

Checking the compressor oil

A little discoloration

(light yellow) Severe discoloration

(light brown)

Purging the pipe at

high-pressure side

Purging the pipe at

low-pressure side

Joining compressor and

accumulator assy'

Setting the compressor and the dryer

Vacuum pumping and pot the electric parts

Charging the refrigerant

Leakage test

Test Run

Pinch-off seal of charge pipes

Finish

Refer to the TROUBLESHOOTING

* For purging the pipe, use HFC-134a as liquid state.

* Never use HCFC-141b, HCFC-22 for purging.

* o not keep the pipes open to air more than 30 minutes.

These process in total should be finished within

30 minutes.

* Rubber caps should be removed just before

compressor is used. Never leave the compressor

without the caps and open to the air.

Be sure to connect the adaptor with vacuum

pump.

Charge cylinder should be exclusive -

use for

HFC-134a.

This is to prevent different refrigerant ( CFC-12,

HCFC-22, CFC-113, HFCFC-141b, R-502) from

mixing with HFC-134a.

IMPORTANT THINGS

* At first, remove the refrigerant by cutting gas

charge pipe.

Check compressor oil
