1. Steps to change water in hand warmer
| steps | Operating Instructions |
|---|---|
| 1. Preparation | Make sure the hand warmer has completely cooled down and prepare distilled or purified water (avoid using tap water), a funnel, and a towel. |
| 2. Open the water filling port | Find the water filling plug at the bottom of the hand warmer and turn it counterclockwise to open it (some models need to use tools to pry it open). |
| 3. Drain old water | Tilt the hand warmer at 45 degrees, squeeze it gently to make the old water flow out from the water filling port, and wipe the remaining water with a towel. |
| 4. Add new water | Add distilled water slowly through the funnel to the water level (usually 80% of capacity), avoiding overflow. |
| 5. Seal inspection | Tighten the water filling plug to ensure there is no water leakage and then turn on the power to test the heating function. |
2. Precautions
1.Water quality selection:Be sure to use distilled or purified water. Minerals in tap water can easily scale and damage the heating element.
2.Water volume control:Excessive water injection will cause water leakage during heating expansion, while insufficient water injection will affect the heating effect.
3.Safe operation:Disconnect the power supply before changing the water, and it is strictly prohibited to operate it while the power is on.
