Abstract: A header for a heat exchanger orients the position of an inlet port at an angle offset from the position of the outlet port on the header body in order to simplify the plumbing of the header within a system. In one implementation of a header for a heat exchanger, the header forms a header cavity defined by an external wall and which is separated into an inlet chamber and an outlet chamber by a dividing wall. An inlet port is defined within the external wall and is in fluid communication with the inlet chamber. Similarly, an outlet port is defined within the external wall and is in fluid communication with the outlet chamber. The inlet port is oriented on the external wall at an offset angle with respect to a position of the outlet port.

Abstract: Automatic adjustment of the control and operation of pool or spa equipment is made based upon a time of year, a geographic location, or both. A controller receives input of the time of year or the geographic location of the pool or spa equipment, or both. The controller then automatically adjusts one or more functions of the pool or spa equipment based upon operational information associated with the time of year and/or geographic location. A user interface connected with the controller may be also used to select a mode of operation, input time or geographic location information, and/or adjust various parameters affecting the automatic seasonal or geographic adjustment of the pool or spa equipment.

Abstract: A pool/spa water treatment system may include a pump and a pool filter. The pump may include a pump inlet and a pump outlet. The pump inlet and outlet may be aligned on a first axis or within a first vertical plane. The pool filter may be offset a select transverse distance from the pump. The pool filter may include a pool filter inlet in fluid communication with the pump outlet. The pool filter inlet and the pump outlet may be aligned on a second axis or within a second vertical plane that is transverse to the first axis or plane. The pool/spa water treatment system may further include a heater. The heater may include a heater inlet in fluid communication with the pool filter outlet. The heater inlet may be aligned with the pool filter outlet within the second plane.

Abstract: A pool filter for use in pool piping or other fluid conveyance system. The pool filter may include a housing defining a fluid chamber for receiving one or more filters. Multiple openings may be defined in the housing for receiving and removing fluid from the fluid chamber. The openings may be approximately the same size and may be located on the housing at similar elevations and/or radial sectors. One or more footings may be joined to the housing. Each footing may include a base portion for receiving anchor members to anchor the housing to a support surface. The footings may be designed to transfer to the support surface predetermined lateral or other forces imposed upon the pool filter by events such as earthquakes and hurricanes. The footings may be separate components joined to the housing by tabs and/or mechanical fasteners.
