Frequently Asked Questions - HT 75 TETRA

How to install the Tetra HT 75 heater?

Attach the suction cups to the designated location, then set the desired temperature with the notched knob (1). Place the heater vertically in the aquarium, preferably near a pump or filter for good water circulation. Make sure to immerse the heater at least to the "minimum water level". Then plug the power cord into the mains.

How to set the temperature?

Use the notched adjustment knob (1) to set the desired temperature (mark 2). The thermostat automatically maintains the temperature with an accuracy of ±0.25 °C. The indicator light lights up when the device is heating.

What does the indicator light mean?

The indicator light turns on to indicate that the heater is heating the water. Once the desired temperature is reached, the light turns off.

How to clean the heater?

Unplug the heater and let it cool down for 15 minutes. Clean the glass tube only with water and vinegar. Do not use detergents, solvents, or acids.

What are the important safety precautions?

Plug the heater only when it is immersed at least to the "minimum water level". Unplug all electrical devices before putting your hand in the water. Let it cool for 15 minutes after unplugging. Use a residual current device (RCD) of 30 mA. Do not use if the cord is damaged.

What is the warranty of the Tetra HT 75?

The warranty is 2 years from the date of purchase. It covers defects in materials or workmanship. Exclusions include incorrect use, breakage of the glass tube, or damage caused by the device.

What to do if the power cord is damaged?

The power cord cannot be replaced. If damaged, the device must no longer be used. Contact customer service.

Can I use the heater out of water?

No, the HT heater must only be connected to the mains if it is submerged in water at least to the "minimum water level". Using it out of water can damage it and pose a danger.

Is the heater accurate?

Yes, the thermostat is extremely accurate with a margin of ±0.25 °C. Minor discrepancies may appear between the setting and the reading of a traditional thermometer.

Instructions for use

Congratulations on the purchase of your Tetra heater thermostat. This TÜV tested heater-thermostat is manufactured from the highest quality materials and uses the latest aquarium heater technology. As a result you can be sure of its accuracy, reliability and safety. Add to this its simplicity of use and you have a heater thermostat that you can simply "set and forget", leaving it to maintain the desired water temperature and leaving you to enjoy your fishkeeping.

Please observe the following instructions when installing and using your Tetra heater thermostat:

1. Fasten the enclosed suction cups to the points provided on the HT heater thermostat (see fig.) Note: Suction cups and holders for heaters and/or filters are not supplied with the AquaArt aquarium.

2. Set the desired temperature (2) using the adjusting knob (1).

3. Fasten the Tetra thermostat heater in the aquarium using the suction cups (see fig.). To ensure the best temperature regulation, choose a place where the water is continuously circulating (i.e. near a filter or pump). Please ensure that the heater is always immersed up to the minimum water level mark.

4. After installing the heater, insert the plug into the mains socket. The thermostat takes several minutes to register the water temperature. The device switches on or off as soon as the temperature deviates from the desired temperature setting by ± 0.25 degrees Celsius. In this way the Tetra HT thermostat heater automatically keeps the water at the desired temperature. The control lamp illuminates whenever the heater is on. Minor deviations between the adjusted temperature of the heater and the indication of an aquarium thermometer are sometimes possible.

Maintenance

To maintain efficient heating, periodically clean the glass tube of calcifications by first unplugging the heater, removing it after it has been allowed to cool for 15 minutes, and then cleaning it only with water and vinegar. Do not use detergents, solvents or acids.
