Projection & pump information
|
For Hurlcon & Waterblade brands ... Suitable for
pools & spas
|
|
The numbers across the top represent the projection
in mm |
 |
|
Above for sheer descent
(projecting sheet)
The maximum flow through the spillway is 50 Ltrs per minute (lpm)
for every 300mm of spillway width. At 50 LPM the projection should be
a little more than 300mm |
Above for "Rain effect" only
Using the maximum flow of 25 Litres per minute (lpm) for every 300mm of
spillway width. At 25 LPM the projection should be a little more than 300mm |
Understanding this chart
The left vertical numbers
represent mounting heights of the spillway box in mm
900mm is the maximum recommended mounting height above the top of the pool
water surface. Any higher than 900mm will cause the water sheet to break up
and feather at the bottom and become untidy. |
The water will taper - a fact of nature
Special note:
these taper details do not apply to the rain effect
spillways, as they do not taper much at all
