INTRODUCTION

This manual describes the LH 1000, which is manufactured by Energy Systems & Design LTD. The installer must have some knowledge of plumbing and electrical systems, as should the end-user of the system. 

These machines are small, but can generate very high voltages. Even 12-volt machines can produce high voltages under certain conditions. Practice all due safety. Electricity cannot be seen and it can be lethal. 

Electricity is produced from the potential energy in water moving from a high point to a lower one. This distance is called "head" and is measured in units of distance: meters (or feet) or in units of pressure: kilograms per square centimeter). "Flow" is measured in units of volume: gallons per minute - GPM (or liters per second - l/s), and is the second portion of the power equation: power [watts] = head x flow. The LH1000 is designed to operate over a fixed range of heads and flows, from 0.6-3m (two to ten feet), employing a cast polyurethane propeller and guide vane assembly. 

The LH1000 uses a permanent magnet type alternator. This design eliminates the need for brushes and the maintenance that accompanies them, while increasing efficiency. The LH1000's output can be optimized by simply adjusting the rotor's clearance from the stator.
