- Page 2 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.
- Page 3 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.
- Page 4 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.

It will display the default temperature when the refrigerating temperature falls into the setting range (+5,-3) Initializing and when the freeze temperature falls into the setting range (+3,-3). When the actual temperature is within the setting range (+5,-3), it will display the default temperature.
- Page 14 B.Refrigerating Temperature Control 1) You may control the refrigerating temperature from 9 to 1 by pressing refrigerating temerature key at 1 interval. 2) If pressing the temperature control button, the temperature will display in the following sequence: 5 ,4 ,3 ,2 ,1 ,9 ,8 ,7 ,6 ,5 . 3) The refrigerating temperature is initialized as 5 .
- Page 15 E.Standard Run 1) You may press the function key to select or give up this funciton. 2) If you select the Standard Run function, the freeze and refrigerating temperatures will be controlled at -18 and 5 respectively. F. Refrigeration Off 1) You may press the function key to select or give up this funciton.
- Page 16 5-4 Test Function Test function is to check the product, PCB, process control and maintenance. After the product function determined by selecting the test switch, you must re-electrify the appliance to run the self-diagonisis function. A.Forced Function 1) If you press the Refrigerating Temperature key and the Freeze Temperature key up to 5 minutes at the same time, the compactor will start running with the display board highlighting FF .

- Page 19 6-3 Crystal Viberation Part Crystal Viberation 4MHz This circuit is used for the geneation of the resonant clock by receiving and sending the logic element information within the core chip. The time on the clock will play the role of time base. The resonance circuit must apply the rated criteria of each element as specification deviation will change the core chip time and disable the running.
