1. Heating tube can be positioned in either a vertical or horizontal position in the water.
2. Temperature controller can be used to adjust water temperature of reef tanks. Ensure that any metal Halide lamp is positioned at least one foot (30 cm) above the tank surface. Metal Halide lighting position is very crucial during summer months because the lamp will continually heat water even after the heater has automatically shutoff after reaching set water temperature. The Metal Halide lamp continually contributes to the heating process through its fluorescent lighting. It is advisable to adjust light output with a dial or digital temperature control unit 1. Place the heater tube unit in water in either vertical or horizontal position. Press two suction cups firmly to glass to adhere heater unit to aquarium. For best results, position the heater towards the bottom of the aquarium in a location that water circulates freely or use a power head (pump) to create the water circulation to ensure uniform heating temperature of water.
2. Set the desired temperature by turning the temperature dial. Wait five minutes until the heater tube is acclimatized to the aquarium water temperature.
3. If the temperature sensor unit separate from heater unit, adhere the temperature sensor unit by firmly pressing the suction cups to the aquarium.
4. Plug the power cord of the heater into the outlet. If power light is on the ON position, the heater is working to maintain set aquarium temperature. If the power light is on the OFF position, the heater has automatically shutoff after reaching set water temperature.
5. After a few hours, check the water temperature with an accurate thermometer, if needed, adjust the temperature setting on the heating unit to achieve desired aquarium water temperature.
SAFETY INSTRUCTION | 1. Do not operate the heater outside of water | 2. To prevent possible electric shock, unplug heater before placing your hands in water | 3. If an extension cord is necessary, a cord with proper rating to avoid overheating | 4. For proper operation, the heater tube should be positioned in a vertical or horizontal position in the water at all times. | 5. Do not operated the heater if the cord or heating tube is damaged in any way. The heater must be discarded. Do not attempt to repair the unit. | 6. Unplug the heater during water change or when removing the unit from water for maintenance. Wait at least 10 minutes for the heater to cool before removing from water. | 7. Make sure that your electrical voltage is the same as the voltage listed on the label of the heater. | 8. To avoid water contact to the heater plug or electric outlet, use a "drip loop" as shown below |
