INSTALLATION

Please Note: Each Model 400 set consists of two pieces--one with a north polarity and the other with a south polarity (the GMX label covers the north pole piece). One north pole/south pole set is recommended for 1/4" to 3/8" lines and most automobile applications. Two sets are recommended for 7/16" to 1/2" lines and most diesel truck applications.
1-1/4" nylon bolts are provided with the Model 400.
1-3/4" bolts are available from GMX International.

1. Insert the bolts through the holes in both units [north pole and south pole].
2. Secure the bolts with wing nuts the regular shaped wing nuts are for normal installations. Locking wing nuts are also provided for more secure installations. Tighten until the wing nuts are snug. Do not over -tighten!
3. If the units do not clamp securely to the tubing, place a sleeve of plastic or rubber tubing over the existing tubing. This is recommended for tubing smaller then 5/16"inside diameter.
4. Install the second Model 400 set 1/2" away from the first following the same installation instructions. Make sure that the north pole units [with the GMX labels] are lined up so that both are facing in the same direction on the same side of the tubing. Also be sure that there is a 1/2" space between the two sets.

SPECIAL NOTES


Placement:

For fuel systems the Model 400 should be placed 6" to 12" away from any high heat source such as the manifold or the exhaust system. And 12" away from diagnostic control centers (computer) and sensors. Sets can be mounted on the fuel line anywhere between the tank and the engine, On fuel injected engines, mount the sets on the line to the engine not the return line. When treating a semi-closed loop system line (ice machine, swamp cooler, dishwasher) install the Model 400 inside the equipment after the circulating pump.

Direction of Placement:

The GMX label is placed over the north pole unit in each set. The direction the fluid flows through the tubing makes no difference.
For best results when placing the Model 400 to treat a particular area or appliance, place the sets at least 8" to 12" upstream (before) the area or appliance to be treated.
Do not place the Model 400 close to an electrical power line or electrical equipment capable of generating strong electrical fields, such as a welder or large electrical motor. This can reduce effectiveness.
For Maximum effectiveness, magnetic conditioning requires a smooth calm flow of fluid through the magnetic field. a partial reversal of treatment may be triggered by turbulence. Therefore always place the Model 400 a minimum of 8"to 12" downstream (after)any pump or other turbulence-causing device.

Non-Ferrous Pipes Only:

Install the Model 400 only on a straight section of non-ferrous (PVC, rubber plastic, copper , or stainless steel) pipe or tubing--not on steel or iron . Don't place it on any tubing to which the magnets stick. The penetration of a magnetic field through iron or steel (except for stainless steel) pipe is minimal, because the magnetic field travels along the exterior of such tubing preventing it from reaching the fluid. In such cases, replace a 12"section of steel tubing with non -ferrous tubing and then install the Model 400 on that section.

Stabilization Period:

On fuel systems: a temporary decrease in mileage and an increase in emissions may be noted after installing the Model 400. This is a temporary condition resulting from the removal of accumulated deposits from the fuel system and combustion chambers.
