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. Before maintenance, the power plug must be pulled out from socket, make the refrigerator power cut to avoid human harm and property loss.

1-1-2. If no suggestions from manufactory, don't change the circuit joined and other operation about circuits change.

1-1-3. Don't use lengthen power line or a pair of wiring boards.

1-1-4. 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	2)Turn off the valve core	3)Solder the pipe onto
		the compactor

4) Turn on the valve	5)Vacuumize and add liquid	6) Onload the pipe nut
core tightly

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.
