Using your Hydor Theo heater is easy. First, choose the right model according to your tank size. Then, use the suction cups to position the heater either horizontally or vertically inside the tank, making sure it's fully immersed. Adjust the temperature using the graduated scale to your desired setting. When it comes to safety, remember that the heater has a PTC heating element and a shatterproof glass tube. But still, avoid hitting or dropping it. In case of abnormal functioning, the heater will automatically stop as the PTC film self - controls the temperature. For maintenance, it's a good idea to clean the heater regularly. Simply unplug it, remove it from the tank, and gently wipe it with a soft cloth. Check the glass tube for any signs of damage over time. If you notice any cracks or other issues, stop using the heater and contact the manufacturer.
