1. Open the box and take out the machine, and check whether the items in the box are consistent with those described in the packing list.

2. Installation of casters: Installation method: take out the whole machine and place it on a flat surface upside down, and insert the wheels into the bottom holes. Once installed in place, use the casters on the ground.

3. The machine should be placed horizontally, and be careful not to tilt during use. Before use,check whether the power supply of the socket is consistent with the parameters on the nameplate of the machine.

4. This machine cannot be used in ultra-high temperature or low temperature places. In hot summer, the water in the water tank is easy to deteriorate and produce peculiar smell and breed bacteria. Please pay attention to replace the water in the water tank in time.

5. Add water: Gently open the lid with your hands (as shown in the picture)
   When adding water, observe the water level through the water level window and control the amount of water added. Please pay attention to the following points when adding water:
   ● For the health of you and your family, clean tap water must be used, and the power plug should be unplugged before adding water.
   ● Do not splash water on the electric machine and its surrounding parts to avoid electric leakage accidents.
   ● Just add water to the “highest water level” water line, otherwise the water will overflow from the machine.

6. Use of ice crystals: The product is delivered with two ice crystal boxes, which contain a certain amount of ice crystals. After the water tank is pushed into place, power on and use.
   ● Note: The ice crystal box should be placed and removed gently to prevent damage to the water circulation system (as shown in Figure 1). The two ice crystals can be used alternately to ensure a long time of humidification and refrigeration in hot summer. ● Note: 1. Do not eat the ice crystals in the box! Do not use the ice crystal box as a toy for children to prevent accidental ingestion!
   2. It is best to freeze for about 6 hours for the first use, and then freeze until it freezes and hardens.

When packaging, storage or transportation is required, it should be drained and then ventilated at room temperature for a period of time, so that the wet curtain paper in the body is completely dry before packaging to prevent peculiar smell due to  umidity. The whole machine is covered with plastic bags during storage, and put it in a box for reuse.

9. Cleaning: After the machine has been running for a long time, the water tank, air inlet and wet curtain evaporator will be blocked by dust and sundries and affect the air volume and cooling effect. It is recommended to clean the water tank, air inlet and wet curtain evaporator once a week.

10. Cleaning method:
    (1) Before cleaning, unplug the power plug from the power socket, and make sure that the fan is disconnected from the power supply before removing the protective cover!
    (2) When the sliding distance of the water tank is dragged outward, it is appropriate that the rear plane of the water tank is 8CM from the back of the body. If the sliding distance of the water tank is too long, the water circulation system may be damaged. After the water tank is cleaned, re-install the water tank into the machine. At this time, the cold air function can be used normally. Otherwise, please check the limit of the water circulation system.
    (3) Remove the filter screen and wet curtain evaporator on the back of the body by hand, rinse the sundries and dust on the wet curtain evaporator with clean water.
