1. PREVENTIVE ACTIONS

1-1 Safety Precautions

Only qualified technicians who have full command and knowledge of the

cooling system and safety inspection are allowed to deliver the maintenance service as specified on the manual.

Please be sure to keep the work place ventilated and safe as this product

adopts the combustible and explosive R600a refrigerant.

Prior to repair, please pull the plug out of the socket from the wall to disconnect the

power to hold the human and wealth harmless.

Do not make any by-pass or circuit change attempt without manufacturer's prior

suggestion.

No prelonged cable or double terminal board is recommended.

For human safety, this procut must be properly earthed. But phone lines and gas

pipes are not recommended for earthing.

1-2 Preparations Before Maintenance

1-2-1.Direct plug in-and-out is recommended when replacing the relay that attaches to

the compactor lead terminal. When inserting and pulling the plug, relay wobbling

will more likely destroy the compactor terminals or relay.

1-2-2.Restart is not allowed within 5 minutes after power off. Immediate plug in-and-out

will disable the restart.

This represents the materials with regard to the A/C circuit and spare part safety.

This represents the materials included in the appliance maintenance.

1-3.Warning

1-3-1 Pay attention to the safety during maintenance as R600a refrigerant is combustible and explosive. 1-3-2 Keep the work place well ventilated without fire source and combustible and explosive objects arround during the maintenance of R600a refrigerator. 1-3-3 Make sure to lay the R600a clean during CYCLE maintenance (ensure the system unblocked by inflating nitrogen under HV and LV state.) 1-3-4 Fire soldering is not allowed until the work place is ventilative without R600a left in the CYCLE. 1-3-5 When no leakage and blocking are found by nitrogen inflation, shut the fire by the soldering fulid pipe (valve core available at one end) at the process pipe. 1-3-6 Adding the fulid by vacuumizing the liquid pipe and screw on the nut.(no fire, appliance, MP3, walkman and mobile phone are allowed during operation)

Note: LOCK RING is only used for pipe connection rather than pipe sealing after adding fluid. If special tools are available for liquid releasing, lead the R600a via pipes to the designated location.

1-4 Special Tools During Maintenance

1)Liquid Adding Pipe

2)Turn off the valve core

3)Solder the pipe onto the compactor

4) Turn on the valve core tightly

5)Vacuumize and add liquid

6) Onload the pipe nut

1-5 Maintenance Method

1.Maintenance Environment

1-1 Pay attention to the safety during maintenance as R600a refrigerant is

combustible and explosive.

1-2 Keep the work place well ventilated without sparks and hot resource around

when repairing the refrigerator's cooling system. Soldering or heating are not

recommended. No smoke also.

1-3 Fire soldering is not allowed until the work place is ventilated without R600a

left in the CYCLE.

2.Refrigerant Remnants Discharging

Prior to reinjecting the refrigerant, conduct the trouble inspection. If the leaking point is found, eject the remained R600a out.

2-1 Open the compactor back cover, reel out the two process pipes and cut them by a knife or pilers to discharge the remained R600a refrigerant.(See figure 1)

cutting position

2.2 Leave the refrigerant for a while (about 30 minutes) and connect to the dry nitrogen to ensure R600a refrigerant is completely discharged and the system are unblocked.

connect to the nitrogen

Gas out

3.Vacuumizing

3-1 After all the refrigerants are out, repair the leaking points and replace the driers and process pipes. The compactor must be fitted with the special liquid process pipes (see below figure)

Special liquid process pipe

fire soldering

3-2 Close the process pipe on the dry filter and connect the compactor's special liquid process pipe to a vacuum pump for vacuumizing.

4.Reinjection of Refrigerant

4-1 When the pipe is entirely vacuumized, fill in the R600a refrigerant in the quantity as shown on the brandplate, and weigh by the electric balance. The injection quantity must be exact to the evel of 2g.

4-2 No fire is allowed around when adding liquid. No pocket mobile phone and walkman are allowed during operation.

4-3 Turn on the pipe nut when finishing the liquid adding, and sort the pipes to avoid the abnormal noise.
