Water delivery system and method for forming same

In a refrigeration apparatus having inner and outer spaced-apart cases each having a plurality of walls, a freezing compartment defined by at least a portion of the inner case, an automatic ice-forming apparatus within the freezing compartment, a water supply line having an outer tube associated with the ice-forming apparatus and extending through the space between the cases, and insitu foamed insulating material in the space between the cases, the improvement comprising:

• a holding element positioned between the cases adjacent the freezing compartment and in contact with the water supply line and the inner and outer cases, said holding element being an insulating material having a preformed configuration for maintaining said supply line in contact and heat exchange relationship along the outer case during foaming of and contact with the insitu foamed insulating material, wherein the outer tube is in contact with first and second abutting walls of the outer case adjacent the juncture of said walls.
