The free-standing CT 4110 model has no inte-grated water tank. Install this model so thatthe wall behind it can absorb the control panelof the toilet, the electric connections and thewater tank, if applicable. It is ideal to set a boxin front of the room wall, as illustrated in Fig. 7.Install the control and operator panel in imme-diate proximity to the toilet (see Section4.3.1.2).

Note that the cassette projects 120 mm(4.72 ″) (a) out of the cassette housing (Fig. 8).The pedestal height (b) ranges from 50 to 110mm (1.97 ″ to 4.33 ″), depending on the model.
