The DRR-K assembly enables the installation of a food waste disposer into an existing sink or washing line so that the full diameter of the inlet to the grinder can be used. This is an advantage when the dimensions and the amount of food waste to be ground are large.
A hole, the diameter of the inlet to the grinding chamber, is cut into the sink or washing line. An extension tube with the same diameter is welded into the hole. A DRR-ring having holes the same size and spacing as the disposer mounting is welded to the other end of the extension. The disposer is bolted to the DRR-ring. A protection cover with a limit switch, which disconnects the electrical supply and stops the motor when lifted, and a flushing nozzle or pipe is included in the assembly.
