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.
