Medo® USA Linear Piston Air Compressors

These are not linear "diaphragm," but true linear "piston" type pumps. Since the only moving part—the piston—floats on a bed of air, a exceptionally long service life can be expected (8 years of continuous life is not uncommon). You will experience exceptionally quiet, energy-efficient operation and clean, oil-free air. An outdoor-rated housing, a grounded power cord, 3/4" hose barb and 115V/60 Hz are all standard. UL-listed. Three-year warranty.

• Extremely quiet.
• Outdoor-rated housing.
• True linear piston.
• Exceptionally long service life.
• Outstanding energy efficiency.

Installation Instructions When Using With Aeration :
**Diffusers, Hose, etc, are sold separately.

1. The first step of installation is to attach one end of the tubing to the compressor. Some tubing will attach directly to the compressor, other sizes may need to use the short piece of rubber hose that is included with the compressor. If tubing is connected directly, simply slide tubing onto outlet of compressor and clamp. If an adapter hose is needed, slide one end onto compressor and clamp - the other end can be connected to the tubing using an adapter so the two sizes will hook to each other.

2. Before attaching the other end of the tubing to the air diffuser, trim the tubing to your desired length. Once trimmed you can attach the tubing to your diffuser and secure with a clamp. You may have to add weights to the tubing to get it to sink. If you purchased self weighted tubing then you will not need to add weights.

3. Install the diffuser in the location of choice in your pond. Note: In freezing climates it is recommended that you do not locate the diffuser in the deepest part of the p ond — this is the warmest water in freezing conditions and should not be disturbed.

4. Put the air compressor in a location so that it cannot fall into the water. While the compressors are weath - er resistant, it is still advised that you shelter your compressor from the elements. Direct rain and snow may shorten the life span of the unit. Note: In the winter damp air can condense on the inside wall of the hose. This can eventually block the hose completely, it is important to check the hose frequently during freezing temperatures. 

For your protection - always unplug the unit from its power source before installing or servicing. Should the unit appear not to be working, do not attempt to reach, remove or disassemble before disconnecting from the power source.

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 into the receptacle.

4. Be sure that a Ground Fault Circuit Interrupter (GFCI) is installed in the branch circuit supplying the aquari - um, fountain or pond equipment.

5. Never remove the ground pin from the plug. Note: A multiple valve assembly is included for use with aquarium lines, this is an accessory item and can be discarded if not needed.
