1. This pump is solely intended to pump air. Do not use for oil, solvents, or any petroleum products (gasoline, diesel, etc.).
2. ALWAYS use a properly grounded AC outlet. Do not immerse the pump’s plug in water or attempt to plug in a wet plug.
3. Provide a “drip loop” for the line cord. This is a loop in the cord below the level of the receptacle or plug that prevents
water from traveling along the cord in the direction of the receptacle.
4. Be sure that a ground fault circuit interrupter (GFCI) is installed in the branch circuit supplying the aquarium, fountain,
or pond equipment.
5. NEVER remove the ground pin from the plug.
