1. It is strictly prohibited to pour boiling water directly into a hot water bag. The water temperature should be around 80 degrees Celsius, and the amount of water poured should not exceed 2/3 of the hot water bag’s rated capacity.
2. After filling with water, make sure to remove any internal air, then tighten the screw cap. Press the bag manually (lay it flat on a tabletop, with the opening and tail sides facing left and right) to check for any leaks.
3. A hot water bag cannot be used if cracks are observed during use.

4. Elderly people and children should be used under the correct guidance of a guardian. For infants and young children, they should be wrapped in cloth and kept away from direct contact; otherwise, the consequences are entirely their own responsibility.

5. When using or storing the hot water bag, avoid applying heavy pressure or sharp objects. It should not come into contact with acids, alkalis, fats, or direct sunlight.

6. The hot water bag should be slightly inflated and placed in a cool, dry place.
