Installation manual

Low Head (LH and LH Pro) turbine assembly

The LH and LH Pro are fully assembled apart from the PMA

stator and rotor.

To attach the stator and rotor follow this procedure:

 Remove the top black fairing

 Open the PVC enclosure that houses the rectifier

 Remove the 4 fixings and washer from the bearing block

 Remove the SD stator from the wrapping

 Attached the 3 wires to the rectifier and tighten; the order

of the wires is not important

 Replace the lid on the PVC enclosure

 Place the stator over the shaft

 Align holes in stator with the bearing block holes

 Place the large washer on the stator

 Insert the 4 fixings and tighten

 Insert the extractor knob in the SD rotor

 Grease the splined shaft

 Place the SD rotor over the shaft

 Tighten the knob; this will draw the SD rotor over the

stator

 Finger-tighten the knob only.

 Replace the black fairing

8.3.5. Turbine Protection

The PowerSpout is encased in a very durable LDPE housing,

ensuring all internal parts are protected from rain, rodents,

children and UV etc.

The LDPE enclosure also helps reduce noise and dampens any slight vibrations. The main

benefit, however, is that there are no exposed rotating hazards that might catch the fingers,

clothes or hair of interested children - ensuring a very safe product. Access to the rotating

parts is only achieved with the use of a tool to remove the covers. All tools to do this for the

PLT turbine are supplied in the optional tool kit.

The internal aluminium bulkhead has been designed to help

control the temperature in the enclosed generation

compartment of the PowerSpout. The Smart Drive generator

has a peak efficiency of up to 80% and will get warm. Heat is

dissipated from the generator core by rotor air flow. The water

cooled aluminium bulkhead and cooler outside air acting

together ensure sufficient cooling for up to 1600 Watts of

generation per turbine.

This warm enclosure helps to ensure that the generator and

electrical junction box do not become corroded from moisture

ingress.
