Abstract: A swimming pool assembly having a plurality of side wall panels certain adjacent ones of which have juxtaposed apertured edge flanges joined together by compression plates each having planar blade and a first plurality of pre-alignment fasteners extending away from the plane of the blade through aligned apertures in each juxtaposed flange and engaging a flange plate surface opposite the blade to temporarily align the side wall panels. Each compression plate further includes a second plurality of alignment towers passing through additional aligned apertures in each juxtaposed flange terminating in wedge receiving slots. Wedges, upon being forced into respective slots, clamp the flanges tightly together. Adjacent panel flanges may further include FML flat surfaces oriented to compensate for panel flange draft angle whereby adjacent panels when clamped together present generally coplanar pool surfaces.

Abstract: A particulate filter ash loading prediction method including the steps of determining a maximum average time for the filter; performing a calculation of a running average of time between regenerations of the filter; calculating an end-of-service life ratio of the filter dependent upon the maximum average time and the running average. The method further includes the steps of determining a delta pressure adjustment factor to compensate for ash loading of the filter depending upon the end-of-service life ratio; and comparing the delta pressure adjustment factor to a predetermined maximum delta pressure value, and, if the delta pressure adjustment factor exceeds the predetermined maximum normalized delta pressure adjustment factor, then indicating that a service or replacement of the filter is needed due to the ash loading.
