1. PRECAUTION
1-1. Security
Only the qualified technician who knows the refrigeration circulatory system technology and
rule of security examination, carry on maintenance operation according to the
handbooks.
1-1-1.
1-1-2.
1-1-3.
1-1-4.
Before maintenance, the power plug must be pulled out from socket,
make the refrigerator power cut to avoid human harm and property loss.
If no suggestions from manufactory, don't change the circuit joined and
other operation about circuits change.
Don't use lengthen power line or a pair of wiring boards.
A socket should be grounding and it is not permitted to connect the
grounding line to such places as water telephone line, gas pipeline.
1-2. Precaution
1-2-1.
When change the relay linking with the lead wire on compressor, must
pull out and insert directly. Don't shake the relay from side to side,
otherwise the lead wire on compressor or relay will be damaged.
1-2-2.
!
The refrigerator is restarted at least 5 minutes interval after power off.
If the plug will be inserted at once after the plug pulled off, the
refrigerator can't be started at once .
This is the data correlated with the security of alternating current
circuit and spare parts of refrigerator.
This is the data for maintaining refrigerator.

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.The special tool for maintaining
1)Liquid Adding Pipe
4) Turn on the valve
core tightly
2)Turn off the valve core
5)Vacuumize and add liquid
3)Solder the pipe onto
the compactor
6) Onload the pipe nut

1-5.Maintaining Method
1 Maintaining condition
R600a is inflammable and explosive, must take care while maintaining
While maintaining the refrigerating system, there are no flame and
inflammable substance around, keep draughty.
Confirm there is no R600a in CYCLE and keep draughty around,
flaming weld is permitted.
Release the remaining refrigerant
Troubleshooting should be carried on before readding the refrigerant, the
remaining R600a should be discharged outdoor after examining leak.
open the afterward cover of the compressor, pull out two technical
pipes, cut off by vice or knife and discharge the remaining
R600a(figure1).
the spot of cutting
Enter dry nitrogen after setting for some time(about 30 minutes) to
guarantee R600a discharged completely and system unblocked.
enter dry nitrogen
the air is out
3
Release vacuum
After discharging refrigerant completely, repair all leaks, change
desiccant and technical pipe, change special pipe for adding refrigerant
on compresso.
special pipe for
adding refrigerant
flame welding
Seal technical pipe in the dry filter, link special technical pipe for adding
refrigerant on the compressor with the vacuum pump and release the
vacuum.
The refrigerant is poured again
After releasing vacuum, the refrigerant R600a is poured into the
charging quantity according to the nameplate, then weigh by electronic
balance.
When filling R600a, the flame is forbidden, don't use mobile phone,
walkman while operating.
After finishing filling refrigerant, screw the pipe bonnet and refurnish the
pipe to prevent from arising the noise.
