1. First, adjust the liquid level: slowly adjust the liquid level regulating valve with appropriate tools. As required, the valve can be rotated counterclockwise or clockwise to increase or decrease the liquid level.

2. Secondly, observe the liquid level: in the process of adjusting the liquid level, observe the change of the liquid level in the ice pipe machine. Adjust the liquid level to the normal range according to the manufacturer's guidance or experience.

3. Finally, test the ice pipe machine: after the liquid level adjustment is completed, restart the ice pipe machine for testing to ensure its normal operation. Observe the refrigeration effect and the stability of liquid level.
