SYSTEM INSTALLATION

After locating a suitable site and completing the earthworks (if any), your PowerPal is

ready for installation. To do this:

1. Bolt the turbine to a turbine stand or base which allows at least 100mm clearance

between the turbine and the ground. The turbine stand should be sturdy and made

from concrete or steel as shown on page 4 of this manual. Bolt spacing is 210mm as

shown in the diagram.

2. Bolt the turbine to the penstock adaptor flange (A – see below). The optimal

diameter of the penstock and PVC fittings is 110mm, to produce the most power. The

minimum diameter is 76mm but less power output may be expected.

3. Turn the handle of the spear valve anticlockwise until the valve is fully open.

Always turn the handle slowly and smoothly.

4. Affix a 135° (or other) elbow bend of PVC into the forebay wall. This should be

fitted with an atmospheric vent (hollow bent pipe), which allows air to escape from

the penstock. The upper opening of the atmospheric vent should be higher than the

water level in the forebay. Divert water away from the forebay or else block the top

of the penstock pipe during the installation procedure.

5. Start installing the penstock. Assembly can begin from either direction but it is

usually easier to begin uphill – the turbine is much easier to move around than the

forebay is. The penstock should be well secured i.e. supported or buried at regular

intervals to support its weight when full – this is particularly important at the bottom

of the penstock so that PowerPal cannot be knocked over. At least two people should

handle the penstock, one uphill and one downhill, until it is fitted into both the elbow

bend and the penstock adaptor flange (B). If PVC is used for the penstock then use

PVC glue to bind the joints but note that the PVC must be dry for the glue to work.
