Installation manual

8.2.2. Mounting TRG

A framed timber base made from 100 x 50 timbers and covered in 12-17mm thick plywood

sheet on-top with a hole 320 x 320mm cut for the exhaust water is a typical TRG turbine

base. A PowerSpout TRG unit is 430 mm high.

A timber or concrete turbine base is less likely to produce resonant noise issues than say a

steel or aluminium base.

8.2.3. Indoor turbine mounting

At sites where no water leakage can be allowed (slip hazards for staff etc) you can attach

sealing strips of adhesive neoprene to the base of the turbine before bolting it down to

ensure the turbine is completely sealed around the base. On the PLT turbine the hold down

fixings are at the rear of the case. To ensure complete sealing at the front of the turbine

under the glazing you can remove front glazing and insert screws through the inside plastic

lip to pull down the case at the front and ensure a tight seal all round.

We also advise that for indoors situation you have a perimeter lip on your turbine base.

Some water seepage is inevitable over time. A lip will trap this seepage and it can then be

drained off rather than spread over the floor.

In situations where there is a high risk of dropping tools into the floor sump you should cover

the floor opening with stainless steel mesh so that any dropped tools or parts will not

disappear under the floor. This tends to apply to industrial sites, including common

applications such as city water intake reservoir facilities for control valves and

instrumentation power, and power for large hydro schemes at the intake. This precaution is

not required at domestic sites where the turbines are typically mounted outside.

A mesh (or exhaust pipe) over the exhaust water opening will prevent access

into the rotating parts from underneath, thus preventing serious damage to the

fingers of inquisitive children. It is important that the installer makes the site safe

and that no rotational or electrical hazards exist.
