You should read this manual carefully before installing PowerPal or allow a trained technician from your local PowerPal Service Center to install it for you. Your PowerPal generator is designed to be simple to operate and easy to maintain. If used in accordance with these instructions your PowerPal will give you many years of service. PowerPal is also designed with safety in mind, but any electric device can be dangerous if not used correctly. At several points in this manual, instructions requiring special attention that must be followed are shown as: SAFETY FIRST • Never allow electrical contacts to become wet. Beware of electrocution. • Never attempt to cut electrical wires or open appliances for repair if the generator is working. Unplug the main cable first. • Inform children of the dangers of electrocution. Never allow them to play with electrical connections. • Keep fingers away from the moving turbine runner. If partly blocked with debris, stop the water flow before cleaning. • If you have any questions about safety, please ask your PowerPal Service Center. • Product must be earth bonded (grounded). OPERATING CAUTIONS • Under conditions of higher water heads than given for each model in this manual, PowerPal is able to generate higher power outputs than rated. This can also occur if the intake pipe diameter exceeds the recommended diameter. If maximum power consumption listed in this manual is exceeded then the PowerPal generator may be irrepairably damaged and require total rewiring. See the section on ‘Technical Specifications’. • Do not forget to grease the bearings at the recommended times. Failure to do this will result in excessive wear on the bearings and shorten their life. • Always ensure that the Electronic Load Controller is set at approximately 220V. Otherwise, the life of lights and appliances may be reduced. Text Box: Warning symbol - beware of hazards or unsafe practices that may cause injury or death. Text Box: Caution symbol – beware of hazards or unsafe practices that may damage the product. Text Box: While electricity improves your life, it can also be dangerous if simple precautions are not followed: Text Box: Your PowerPal generator is designed for simple operation and low maintenance. However, the following operating cautions must be followed to ensure a long life for PowerPal: POWERPAL COMPONENTS Inside your PowerPal box you will find: • 1 x generator-turbine assembly • 1 x penstock adaptor flange, internal diameter 110mm • 1 x rubber gasket • 4 x M10 foundation nuts and bolts • 1 x control panel including electronic load controller • 1 x ballast load • 1 x Guarantee Card • 1 x this instruction manual. Please advise immediately if any parts are missing. Complete your Guarantee Card and have it signed by your PowerPal dealer. The PowerPal system consists of two major components – a hydroelectric generator and an electronic load controller. Other components are necessary and these can be purchased locally. The penstock (intake pipe) should be made from either steel or schedule 40 PVC. Your PowerPal dealer can advise you about this. Therefore, other parts which are not included in the box but which are required to make PowerPal work are: • a length of steel or PVC pipe with internal diameter 110mm. Pipe length will affect your power output (see page 5). • electrical wire from generator to house. See the section on ‘Technical Specifications’ for the correct wire size. • household wiring. These are available from your dealer or local electrical store. SYSTEM DIAGRAM The following diagram shows how the non-electrical components fit together.

There are two critical factors that influence power output – head and flow. Head is the vertical distance between the turbine and the water source (forebay), measured in meters. Flow is the amount of water that passes through the turbine at any instant, measured in litres per second (l/sec). See Page 17 for detailed head, flow rate and output data for the three T2 models. Measuring Gross Head The gross head is the vertical height from where the water flow enters the penstock down to the level of the turbine. It is shown in the System Diagram. To measure this, use a tape measure and a clinometer or spirit level etc. A less accurate but useful alternative is to make your own level from a transparent tube half-filled with water. Attach this to the top of a 1m long stick and then point this horizontally at a point further up the slope as though it were a spirit level. By going to ...
