Whisper Air Pumps

Patented dome shape and sound-dampening chambers mean virtually silent operation. Improved design, with suspended pump motor and rubber feet, eliminates vibrations while thick walls insulate motor noise. Helps maintain optimum oxygen levels in your aquatic terrarium and delivers ample airflow for deepwater applications. Use with undergravel filters, airstones, and bubble wands.

Installing your Whisper Air Pump

Basic Installation

1. Place the Whisper Air Pump on a surface lower than the water level of the terrarium. To avoid damage for accidentally spilled water, do not place the pump directly below the terrarium.
2. Use a check-valve between the pump and the terrarium. It helps stop water from siphoning into your air pump in case of an electrical power failure or when removing filters from terrariums.

Above-Tank Installation

1. Place the Whisper Air Pump on a shelf at least 12" higher than the water level of the terrarium, but not directly above the terrarium.
   NOTE: The shelf should have a raised edge to prevent the pump from sliding off.

Custom Installation

1. Use a Whisper Air Pump with two ports for alternate installation. NOTE: Use a Tee connector with your two-port Air Pump for applications that require only one source of air.
2. Air-control valves create multiple air sources. Use the valves to route the air from the Whisper Air Pump to different tanks, filters, airstones or air-operated ornaments.
3. Adjust the air-control valves to regulate air supplied to tanks, filters, airstones and air-controlled ornaments. On three-way valves, Knob 1 regulates airflow to Nozzle 3, and air flows through Outlet 2 unimpeded. Use end caps at the end of the line.

Maintaining your Whisper Air Pump

• Clogged airstones usually cause airflow loss. They become blocked as algae, floating debris, and mineral deposits accumulate in the pores over time. If you notice a diminished airflow, blow through the airstone yourself. If this is difficult, replace the airstone.
• Worn diaphragms or other rubber parts can also diminish airflow.
• Clean the outside of the pump with a damp cloth and mild detergent.
• Pump mechanism never needs oil.
