Important Safety Instructions
- The heating rod must be completely submerged at all times during operation. Do not allow it to be exposed above the waterline.
- Do not place the rod directly on or close to substrate/sand, as this obstructs heat dissipation.
- Monitor your water level regularly — evaporation can expose the heater. Top up the tank as needed.
- Before performing water changes or removing the heater, switch off the power at least 15 minutes in advance and allow the rod to cool fully before handling to prevent cracking or damage.
