5.Operate like this for 15 minutes while observing any unusual noise, excessive temperature or other problems and if OK then switch on the power to the user. Up till now the ballast load has been receiving all the power and should be hot, but once switching on the user load the power to the ballast load will fall.

6.The voltage should remain stable as loads are switched on or off. If the voltage falls below 220V then check the water flow conditions. The voltage may need to be checked and adjusted if the water flow rate changes e.g. a prolonged dry period may gradually reduce it.

Do not allow electrical contacts to become wet. Use dry hands. Beware of electrocution.

Avoid plugging appliances directly into PowerPal without using the load controller. Incorrect voltage may result, which can damage your appliance.

7.Whenever shutting down the system, first close the valve to reduce the flow rate and once the voltmeter shows 100V, switch the control box to the ‘off’ position. Then close the valve fully to stop the system.

CARE AND MAINTENANCE

General care for your PowerPal will enhance its life. Following the instructions in this manual is important.

Try to install PowerPal in a place that is unlikely to be flooded. A simple shelter with a roof will also help protect the generator from rain or else a small shed can be built and locked if security is an issue. If the inside of the generator assembly does become wet it will require drying. No permanent damage will result, but check the bearings to see if they have collected water. Do not try to dry it near a fire. Before using again, make sure that the power socket is also dry. Condensation inside the generator is normal in tropical areas and will not effect the performance of PowerPal.

Greasing the Bearings

PowerPal has three bearings, two in the generator and one in the turbine. The generator bearings are maintenance-free while the turbine bearing has been greased in the factory ready for use but requires re-greasing every 3 months of continuous use. To do this, clean the nipple on the bearing casing and apply extra grease with a grease gun. There is no need to stop the turbine to grease this bearing.

Failure to grease the bearings on time will shorten their life and require their replacement. The increased friction will also reduce power output. Always clean the nipple before greasing.
