Function introduction

1. Keys

A. Hi Humidity: High Humidity Mode
B. ON/OFF: start up or shut down the system
C.∧: increase temperature of the cooling chamber
D. V: decrease temperature of the cooling chamber

2. Names of functions of display screen

1、High Humidity figure
2、Temperature region digitron
3、Temperature (°C) figure

3. Display control

● Power on for the first time: all shines for three seconds with ringing of start bell. Defaulting temperature of the cooling chamber is 5 °C.

● Normal operation display:

Temperature display region: when there is a failure, it will show failure codes by turn at a priority order; without failure, it will show the set temperature. High Humidity figure: shine when the system is under High Humidity Mode.

● Display control:

1、Under the normal pattern, it will not shine any more after thirty seconds without opening and key operation;

1. When the door is under open state, the display will shine all the time and it will stop shining thirty seconds after the door is closed.

2. When a failure happens and it is within "Failure Code", the screen will shine for one time and stop to shine after thirty seconds (If the buzzer h as been ringing for a long time, press any key to cancel the failure bell);

4. User Mode operation

- Start-up and shutdown

Troubleshooting

Before overhaul, please read following content carefully

Phenomenon	Possible reasons and matters needing check
Inoperation	Not charged with electricity or loose pluggingExcessively low voltage
Poor freshness	High temperature regulationToo much foodHot foodFrequent door operation (open and close)Incomplete door closingHeat source nearby
High noises	Uneven floor and unsteady placementRight placement of accessories
Foreign odor	Unsealed wrapping of odorous foodSour foodUncleanliness interior

If the situation still exist after checking all above matters, please contact our company's After-sale Department. The damaged power cord must be replaced by maintenance personnel appointed by our company for the sake of safety.

Non-failure phenomenon

Within the capillary tubes, refrigerant fluid flows very fast, sometimes carries few air bubbles, which might cause irregular noises at the entrance.

When air humidity is relatively high, areas around the door may be damp and you can clean it with a dry cloth.
