1: The diving heating rod needs to be completely submerged in the water. Placing it near the filter outlet is beneficial for even heat distribution.
2: Adjust the temperature. The heating rod should be kept at the factory pre-selected temperature for twelve hours before being adjusted to the desired temperature.
3: The heating plate should not be buried in sand for use, otherwise it may cause incorrect perception of water temperature.
4: Do not use it as a backup function when leaving the water or power off. When changing the water in the fish tank or removing the heating element from the water surface, power off it 10 minutes in advance and cool it down before taking it out.
5: Do not use a non body cover to cover the body, otherwise the body circuit will not be able to perceive the correct water temperature, resulting in incorrect action, and the water level will not be able to be detected properly when disconnected from the water.
