Two Ways to Install Your Deep Water Air Pump

1. Place the Tetratec Deep Water aquarium air pump on a surface lower than the water level of the aquarium or on the floor. To avoid damage from accidentally spilled water, do not place the air pump directly below the aquarium. Important: Always use a Whisper Check Valve in the airline between the air pump and the aquarium. In the event of a power failure, or when removing filters from the aquarium, the Check Valve will help prevent water from siphoning into the pump.
   
   
2. Place the Tetratec Deep Water aquarium air pump on a shelf at least 12 inches higher than the water level of the aquarium, but not directly above the aquarium. The shelf should have a raise edge to prevent the air pump from sliding off.

Note: For use with saltwater aquariums, place the air pump on a shelf as described in option 2, and use a Whisper Check Valve.

Customizing Your Installation with Whisper Valves
Your air pump is powerful as well as quiet. Depending on the size and depth of your aquarium(s), you can power several airstones and filtering devices with one air pump. You can customize the installation by routing air from the air pump to different tanks, filters, airstones, and air operated ornaments.

Directions: Plug into 110/120V Ac outlet only. Be sure to allow for a "Drip Loop" (part of the cord that dips below outlet receptacle or connector). The "Drip Loop" prevents water from running into outlet.

Attach one end of airline tubing to air outlet(s) on your Tetratec Deep Water air pump. Attach other end of airline tubing to filter(s), airstone(s), or air operated ornament(s). Pump is now ready to plug in.

Pump reaches normal operating efficiency after several hours.

Caution: To prevent back siphoning when removing filter(s), airstone(s), or air operated ornaments from aquarium do the following.

1. Install a Whisper Check Valve.
2. Leave pump running.
3. Remove end of tubing from pump nozzle and tape this end to the very top frame of the aquarium, then you can safely remove your filter(s), airstone(s), or air operated ornaments from the aquarium.

The Whisper Check Valve allows you to more safely keep your pump on the floor. It helps stop water from siphoning into your air pump in case of an electrical power failure or when removing filters from aquariums.

Loss of Air Flow: Apparent loss of airflow is usually caused by clogged airstones. If you notice a diminished air flow, try blowing through the airstone yourself. If this is difficult, replace the airstone.

Tips:

1. If you replace the airstones in your filter(s) regularly, you do not have to be concerned about loss of air due to clogged airstones.
2. Loss of air pumping action is most often caused by a clogged airstone. Check your airstone by sucking a small amount of water into the airstone. If you cannot blow it back through, neither can your pump.

Cleaning: Use only a damp cloth and mild detergent on the outside of the pump.

Lubrication: Pump mechanism never needs oil.
