Introducing the SZELAM submersible aquarium heater, available in 100w, 300w, 500w, and 800w models, designed to create the optimal living environment for your beloved fish, shielding them from the harshness of winter. Featuring a Dual Digital LED Temp Display, this heater allows you to easily monitor both the set temperature and the actual water temperature simultaneously.

The thickened Protective Guard and Explosion-proof Heating Tube ensure the safety of your aquarium pets, preventing any risk of scalding. Additionally, the anti-overheating and shatterproof design eliminate worries about potential harm to your fish.

Installing the heater is a breeze, thanks to the two suction cups that securely lock the black protective guard in place. You can position the heater diagonally, vertically, or horizontally, as long as the heating element is fully submerged in the water.

Precision is at the heart of the SZELAM aquarium heater's water temperature control. We have enhanced the sensitivity of the temperature probe, significantly improving the accuracy and stability of the temperature readings. Furthermore, we have upgraded the length of the probe to 5.9 inches, ensuring optimal performance.

In the unlikely event of any issues, the heater is equipped with a suite of error codes and solutions to assist you:

E0: Out of water protection - the heater automatically shuts off when out of water. E6 and E7: Controller fault - apply for a replacement. E8 and E9: Temperature probe fault - apply for a replacement.

It is essential to regularly check and clean the heating element, especially during the winter months when it operates 24/7. This maintenance ensures the element functions properly and prevents inaccurate temperature monitoring due to dirt buildup.

Please note the following important tips for optimal use:

1. Place the heating element near water flow or a power head for a more stable and comfortable environment.
2. Do not use the heater if the cord or heater is damaged.
3. The controller must never be placed in the water.
4. Unplug the heater before installation.
5. Unplug the heater when cleaning the tank or changing water, and ensure it has cooled down completely before removing it from the water.
6. Do not place the heater in the sand, as this can cause inaccurate heating.
7. Children or minors should be supervised by adults when using the heater.

Experience the upgraded precision of the SZELAM aquarium heater, designed to provide your beloved fish with a safe and comfortable living environment.
