About NO.17 Small Submersible Aquarium Heater 150W, Mini

1,Use of heating rod: The heating rod should be equipped with a water pump for water circulation. When standing vertically, the temperature control probe is easily heated by the heat of the bottom heating tube. The surrounding water temperature does not reach the temperature and the heating rod shows that the temperature reaches the temperature and stops working. At the same time, gap heating will occur. Horizontal placement can solve the above problems very well. 2,Temperature is not accurate: a:The thermometer scale used by the customer is different: b:The temperature detection instrument is placed in the same position as the heater bar; c,more temperature measurement samples are required. d.The heating rod needs to be fully submerged for 15 minutes before the actual temperature in the aquarium can be detected. 3,The heating rod heating indicator is on but not heated, and the temperature cannot be added:If the heating tube is not heated, the heating tube is damaged. : If there is heat, it means that the power of the heating rod is small, and the power is selected. Or the customer's water circulation is too large, resulting in heat loss! 4,Temperature is not accurate after setting the temperature: Understand that the incorrect setting temperature is not the current display temperature. If you set 26 degrees, the actual water temperature is 30 degrees, the display temperature is 30 degrees, the customer will say It has not reached 26 degrees for the power supply for a long time. The heating rod is not a cooling rod, and the temperature cannot be lowered! 5,The heating rod shows E2: over temperature protection, there is no pump circulation convection, and the heating rod is locally heated. 6,There is cotton dust inside the heating pipe: the heat-proof cotton at the bottom of the heating pipe is scattered during transportation,it is a fire-resistant and heat-resistant,no affect
