, Manifold gauge.

Evacuate for more than forty minutes after connecting

manifold gauge hose and vacuum pump to high (drier) and low (compressor) pressure sides.

Vacuum

Pipe Cutter, Gas welder,

N2 gas

Confirm refrigerant (R-134a or R-600a) and oil for compressor and drier. Confirm N2 sealing and packing conditions before use.

Use good one for welding and assembly. Weld under nitrogen gas atmosphere. Repair in a clean and dry place.

Parts replacement and welding

Nipper, side cutters

Cut charging pipe ends (Comp. & Dryer) and discharge refrigerant from drier and compressor.

Remove refrigerant Residuals

ToolsContentsProcess

Installation should be conducted in accordance with the standard installation procedure. (Leave space of more than 5 cm from the wall for compressor compartment cooling fan mounted model.)

Transportation and installation

Copper brush, Rag, Tool box

Remove flux from the silver weld joints with soft brusher wet rag. (Flux may be the cause of corrosion and leaks.) Clean tools and store them in a clean tool box or in their place.

Compressor compartment and tools arrangement

Electronic Leak Detector, Driver.

Check leak at weld joints.

Note :Do not use soapy water for check.

Check cooling capacity

- Check condenser manually to see if warm.

- Check hot pipe manually to see if warm.

- Check frost formation on the whole surface of the evaporator.

2. Precautions During Heavy Repair

COOLING CYCLE HEAVY REPAIR

1) Remove retained refrigerant more than 5 minutes after turning off a refrigerator. (If not, oil will leak inside.)

2) Remove retained refrigerant by cutting first high pressure side (drier part) with a nipper and then cut low pressure side. (If the order is not observed, oil leak will happen.)

Removal of retained refrigerant.

- Use special parts and tools for R-134a or R-600a.

2) Check leakage with an electronic leakage tester.

3) Be sure to use a pipe cutter when cutting pipes.

4) Be careful not the water let intrude into the inside of the cycle.

3. Practical Work for Heavy Repair

COOLING CYCLE HEAVY REPAIR

1) Remove residual refrigerant more than 5 minutes later after turning off the refrigerator. ( If not, compressor oil may leak inside.)

2) Remove retained refrigerant slowly by cutting first high pressure side (drier part) with a nipper and then cut low pressure side.

* When replacing a compressor:

Weld 3 and 4 parts by blowing nitrogen to the low pressure side. Note) For other parts, nitrogen blowing is not necessary because it does not produce oxidized scales inside pipe because of its short welding time.

1) Check the amount of refrigerant supplied to each model after completing vacuum degassing.

2) Evacuate bombe with a vacuum pump.

3) Measure the amount of refrigerant charged.

- Measure the weight of an evacuated bombe with an electronic scale.

- Charge refrigerant into a bombe and measure the weight. Calculate

the weight of refrigerant charged into the bombe by subtracting the weight of an evacuated bombe.

4.Refrigerant charging

2) Operate compressor while charging refrigerant. (It is easier and more certain to do like this.)

1) Be sure to charge the refrigerant at around 25C.

2) Be sure to keep

1) Observe the safety precautions for gas handling.

2) Use JIG (or wet towel) in order to prevent electric wires from burning during welding. (In order to prevent insulation break and accident.)

3) The inner case shall be melted and insulation material (polyurethane) shall be burnt if not cared during welding inner case parts.

4) The copper pipe shall be oxidized by overheating if not cared during welding.

5) Not allow the aluminum pipes to contact to copper pipes. (In order to prevent corrosion.)

6) Make sure that the inner diameter should not be distorted while cutting a capillary tube.

7) Be sure that a suction pipe and a filling tube should not be substituted each other during welding. ( High efficiency pump.)
