5. As the water flow starts to create electric power, the voltage will rise until the
voltmeter on the control box reads 230V. If the voltage continues to rise, adjust
the water flow with the spear valve so that the voltage stays at 230V. The voltage
will then fall to 220V after a minute or two.
Always turn the valve handles slowly and smoothly to avoid sudden changes
to water pressure in the penstock. Sudden changes can cause a 'water
hammer' effect and rupture the penstock.
6. Operate like this for 15 minutes while observing any unusual noise, excessive
temperature or other problems and if OK then use the switch on the control panel
door to 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.
7. 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.
Do not plug appliances directly into PowerPal without using the load
controller. Incorrect voltage may result, which can damage your appliance.
8. Whenever shutting down the system, first close the spear valve to reduce the flow
rate and once the voltmeter shows 100V, switch the control box to the 'off'
position. Then slowly close the spear valve and then gate 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.
Install PowerPal in a place that is unlikely to be flooded. A simple shelter with a roof
is required to protect the generator from rain or else a small shed can be built and
locked (preferable). 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, which is 'tropicalized'.
Greasing the Bearings
PowerPal has two bearings in the turbine that require periodic attention – one near the
runner inside the turbine casing and the other where the turbine shaft attaches to the
generator. Both have been greased in the factory ready for use but require re-greasing
