Specifications

Cable length 1.8 m. Operating voltage 240 V / 50 Hz. As a guide, allow about 1 watt per litre; if your tank sits between sizes, choose the next wattage up.

Installation

• Mount the heater fully submerged, near good flow, and off the substrate.
• Fit the suction clips on the top third of the heater, not on the heating element.
• Do not plug the heater in unless it is fully submerged. Use a drip loop on the cord.
• Set the temperature on the dial, then check with a thermometer at the far end of the tank.
• Unplug and allow 10–15 minutes to cool before removing the heater from the water.

Always follow directions on product packaging.
