The CL4 Professional Range
The CL4 Professional Range  Ref: CL4
The site installation of the CL4 model is unique to the range, in that pressures on the casing welds brought about by the weight of water (approx 1 ton per bay without media) requires that the unit needs to be placed on a firm level concrete base, and partially encased in concrete to provide lasting stability and a long life. This applies regardless of whether the unit is pump or gravity fed, and the attached diagram illustrates the basics of what needs to be achieved. Should any further technical clarity be required do not hesitate to contact the Alternative Aquatics office.
