Installation and Normal Operation
Before Installation
Make sure that the pipes have been properly flushed before installation of the machine.
We know from experience that welding rods, plastic bags, rags and other debris will block the turbine.
This may result in damage and poor performance.
Before Use
Fill oil in Power Unit.
Programming
The 270 FT Power Unit has a four programme devise build in. Those programmes control the spacing of the
helical pattern, the pitch angle.
The pitch angle is the angle the nozzle rises or lowers for each revolution of the nozzle in the horizontal plane.
Because of the pre-programmed, varying helical pattern, the Power Unit automatically makes the helical
pattern closer at the lower angles (0° to 30°).
The steps between the programmes are fixed and not adjustable.
The step between programme
1 to 2 is 1° pitch
2 to 3 is 1° pitch
3 to full is 5.5° pitch
All values valid at 90° lift
The basic pitch angle, the pitch angle of programme 1, can be pre-set within certain limits by turning the
adjusting screw on the programming unit. Because of the fixed steps between the different programmes,
adjusting programme 1 also affects the other programmes.
The useful angle of programme 1 is 0° to 1.5°.
