Abstract:

A method to assemble a nozzle-fastener assembly including: inserting a hollow stem through a wash liquid direction device; inserting the hollow stem through a mounting block; positioning an inside surface of the mounting block against a curved surface of a wash liquid distribution pipe and an outside surface of the block against the wash liquid direction device; attaching the nozzle-fastener to an aperture in the pipe such that an inlet to the hollow stem is in fluid communication with a wash liquid passage in the pipe, wherein the stem extends through the mounting block and the wash liquid direction device, and the stem includes a outlet for the wash liquid passing through the hollow stem and to the wash liquid direction device, and wherein the wash liquid direction device and mounting block are held together by the attachment of the nozzle-fastener to the aperture in the wash liquid pipe.
