The assembly measures 230mm across the front, 267mm from front to back and 551mm overall height. The tank body is 450mm high. Upper and lower wall-mounting holes are spaced 340mm vertically, centre to centre, on each side.

The removable knife holder and drop-on lid provide access for loading and cleaning. The maximum blade length is 335mm, with a handle depth of 85mm.

A ½-inch lever-operated ball valve controls the water inlet. Water enters at the base and leaves through a ½-inch overflow connection near the top; the overflow can be connected to drainage.

The unit includes a serviceable 3kW / 220V heating element with an adjustable 50–110°C thermostat. Switch off the electrical heating whenever the incoming water is manually shut off to prevent dry heating and element damage.
