This represents the materials with regard to the A/C circuit and spare part safety.
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.
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.
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. 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.
1-2 Preparations Before Maintenance
This represents the materials included in the appliance maintenance.

1-3.Warning
1)Liquid AddingPipe 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
1-3-1 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

1-5 Maintenance Method
3
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

3-2 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
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
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.
