Easy Tune Stream Engine! With a proper installation and a little routine maintenance, your Stream Engine will provide you with years of trouble-free operation. This manual will help you to install your machine as well as assist you in trouble-shooting and problem solving.
Page 3: Introduction
The Easy Tune’s output can be optimized by simply moving the upper part of the generator. This manual describes The Easy Tune Stream Engine, which is manufactured by Energy Systems and Design Ltd. The installer must have some knowledge of plumbing and electrical systems, as should the end user of the system.

Another technique is to use a surveyor's transit. This method can also be approximated using a carpenter's level along with a measuring stick or a "story pole." This technique is also done in a series of steps to arrive at the overall head. A variation on this method is the use of altimeters. GPS equipment could also be used to measure elevation.

The weir method is more versatile and may prove useful for higher flows. This technique uses a rectangular opening cut in a board or piece of sheet metal set into the brook like a dam. The water is channeled into the weir and the depth is measured from the top of a stake that is level with the edge of the weir and several feet upstream.
Page 6: Intake, Pipeline & Tailrace
INTAKE, PIPELINE, AND TAILRACE Most hydro systems require a pipeline. Even systems operating directly from a dam require at least a short plumbing run. It is important to use the correct type and size of pipe to minimize restrictions in the flow to the nozzle(s).

It is recommended to have the Stream Engine in a small enclosure or under some cover to keep it dry and provide a place for auxiliary equipment.
Page 8: Wiring And Load Center
In higher power systems, it is usually better to use an inverter to convert battery voltage to regular 120 volt AC power at 60Hz (cycles per second), or 240 volt 50Hz in some countries. This has been made feasible with the advent of reliable high power inverters. Thousands of home power systems are in operation with only AC loads.
Page 9: Design Example
DESIGN EXAMPLE This example shows how to proceed with a complete installation. The parameters of the example site are: -120 feet of head over a distance of 1000 feet -a flow of 30 gpm (most of the time) -100 feet of distance from the house to the hydro machine -24 volt system The first thing we do is determine the pipeline size.
Page 10 Let's say we can accept around a 10% loss. This is 30 watts out of the original 300. The formula for resistive loss is I R = watts. I = Intensity (current in amps) and R = Resistance (in ohms). (10 amps)²...
Page 11: Output Adjustment
OUTPUT ADJUSTMENT The Easy Tune Stream Engine has the unique feature of being adjustable for maximum power while it is running! When the machine is fully installed and running, it can be easily adjusted for maximum power. This is done by measuring the output current or amps while the machine is generating power. Simply use your digital multi-meter to determine the highest output reading and set the machine at that point.
Page 12: High Voltage
High Voltage AC Transmission When the machine is used to generate high voltage AC for long distances, the output can be maximized by using the procedure for output adjustment. The meter is used with the AC scale and the machine is adjusted for the highest AC voltage.

Page 14 The upper casting is now removed by tightening the 5/8” bolt that is supplied with the machine into the center hole in the top of the machine. Make sure that the adjustment knobs are backed off enough to clear the casting when it is raised for removal. Then tighten the bolt. When the bolt contacts the shaft end it will start to raise the upper part of the generator until it is high enough so that it can be pulled off.

The photo shows how to remove the hub for a machine with a low flow runner. IMPORTANT Bearing maintenance is important. You should replace bearings on a regular basis. If they are worn, severe damage to both the rotor and the stator can result. Even if the bearings are not worn, changing them once per year will help keep the area free of corrosion and make future bearing changes easier.

Page 18: Wiring
A Stream Engine Easy Tune® Generator wired delta Moving the wires with the yellow ends for wye To change wiring from delta to wye, move the wires (orange, brown, and blue) with the yellow ends on the rectifier to the empty stud on the transparent terminal block. Using the wye connection will raise the voltage and lower the current.
Page 19: Wiring
Parallel Wiring Look at the photographs of the wiring for the parallel connections and you will see that only two of the terminal screw connections are used for each section or phase. The terminal blocks are divided into three sections which are separated by the mounting screws that have a flat hex head. Only the two screws at either side are used in the parallel scheme.
Page 20: Installation Examples
INSTALLATION EXAMPLES note: The machines pictured may vary by model but installation principles are the same for all Stream Engines from ESD. A Stream Engine installed using PVC pipe and union valves. Under construction; a 30’ head site shown before gravel base was added. Installation with flexible pipe.
Page 21 Note pressure gauge installed by drilling and tapping the T fitting and using a small valve. This allows removal of the gauge to prevent freezing damage to the gauge. Following is an example of what NOT to do for a Stream Engine installation. An installation of this sort will result in a huge loss of power.
