Thanks to its high quality Quartz Glass material and its Protective Sleeve, this aquarium heater is shatter resistant & more durable than conventional glass heaters. A durable thick plastic outer housing wraps up the glass tube, acting as a buffer between your fish and the hot heater with non-conductive plastic outer sleeve so fish/turtle/plants can't be burnt.

The 3 suction cups provided fit into the protective outer sleeve in a very unique way, allowing the heater to be installed horizontally or vertically under the water.

This fish tank heater can automatically control the temperature. It will automatically turn off as the temperature rises above the internal setting you choose, and turns back on like clockwork once it sufficiently cools down. Set and adjust the desired temperature with the use of the Temperature Controller on the top, allowing for accurate thermal control via the easy set thermostat for precise temperature regulation.

The operation instructions are as follows: 1. The 500 watt aquarium heater could be installed horizontally and vertically, and it should be immersed into water completely. 2. When the water is not enough, the heater reads E1, and need to add more water. 3. It takes about 10~15 minutes to get used to the water temperature. Then adjust and set the desired temperature value. 4. It starts to work if the actual temperature value is lower than the settled value, unless it doesn't work. 5. We suggest the horizontal installment.

Note: Due to some unpredictable external factors, it's normal that the temperature difference is ±5°F. The temperature zone is 2 degrees each click. The small dot between each 2 numbers means 2 degrees difference.
