POWER SUPPLY CORD DRIP LOOP

- To avoid the possibility of the appliance plug or receptacle getting wet, position aquarium stand and tank to one side of a wall mounted receptacle to prevent water from dripping onto the receptacle or plug. A “drip loop”, shown in the figure, should be arranged by the user for each cord connecting the aquarium appliance to a receptacle. The “drip loop” is that part of the cord below the level of the receptacle, to prevent water travelling along the cord and coming in contact with the receptacle. If the plug or receptacle does get wet, DON'T unplug the cord; disconnect the fuse or circuit breaker that supplies power to the appliance. Then unplug and examine for presence of water in the receptacle.

• Close supervision is necessary when any appliance is used by or near children.
