 Warnings and Warm Tips

1. Always keep the heater rod fully submersible to avoid heater damage and accidental burns.
2. Unplug the heater for 15 minutes or so before water change or cleaning the fish tank. Otherwise, it would melt the case.
3. When the display shows error “E3”, long press control ball and plugs in together .then can rotate the control ball to set the same temperature with the fish tank.
4. Regularly clean the heating plate. If the heating plate is attached with impurities, the heating efficiency will be reduced.
