• the vacuum installation unit 1 is provided with a first vacuum connection 71 connecting the discharge connection 3, from behind the discharge valve 5 in the flow direction of sewage (indicated by a block arrow), with the control unit 4 and a second vacuum connection 72 connecting the control unit 4 with the discharge valve 5.
• the first vacuum connection 71 and the second vacuum connection 72 pass through the fire-resistant plate 2.
• the vac- uum connections that pass through the fire-resistant plate are made of steel or other fire-resistant material and form integral or fixed parts of the fire-resistant plate.
• the discharge valve 5 in this embodiment is a vacuum operated discharge valve, whereby the necessary vacuum is tapped from just behind the discharge valve in the flow direction of sewage (indicated by a block arrow), led to the control unit 4, which then directs said vacuum to the discharge valve 5 for opening the same when the flush sequence is initiated.
• the control unit 4 is provided with an activating means (not shown).
• a third vacuum connection 73 is provided between the control unit 4 and the water valve 6. Further, the vacuum installation unit 2 is provided with a water connection 61 between the water valve 6 and the toilet bowl 8 (Fig. 2), which water connection 61 passes through the fire-resistant plate 2, as the water valve 6 and the toilet bowl in this embodiment are on opposite sides of the fire-resistant plate 2.
• the water connection that passes through the fire-resistant plate is made of steel or other fire-resistant material and forms an integral or fixed part of the fire- resistant plate.

• Fig. 3 shows another embodiment of the present invention.
• the same reference numerals are used for the corresponding elements as in the embodiment of Fig. 1 , and are therefore not discussed in detail in this connection.
• the main difference is that the discharge valve 5 is attached to the second end 32 of the discharge connection 3, i.e. it is located on the second side 25 of the fire resistant plate 2.
• This also means that the first vacuum connection 71 between the discharge connection 3 and the control unit 4 as well as the second vacuum connection 72 between the control unit 4 and the discharge valve 5 do not pass through the fire-resistant plate 2.
• the first vacuum connection 71 is, however, also connected to the discharge connection 3 behind the discharge valve 5 in the flow direction of sewage (indicated by a block arrow) as described in connection with Fig. 1.
• This embodiment provides access also to the discharge valve 5 and its connec- tions without removal of the fire-resistant plate 2.
• the installation principle corresponds to what is described in connection with Fig. 2. This would also apply to any other modifications made to the arrangement of the components and their respective connections.
• the basic purposes of the vacuum installation unit 1 are: to function as a fire- insulation between the sanitary room and the outside service space at the location of (or opening for) the vacuum toilet unit; to function as a support for the components of the vacuum toilet unit; and to function as a support and lead- through for the appropriate connections required for a vacuum toilet unit installation.
• the description and drawings are only intended to clarify the basic idea of the invention.
• the arrangement of the different components and their respective connections in relation to the fire-resistant plate may thus be chosen as desired.
• the discharge valve may e.g. also be an electrically operated disc valve.
• the invention may thus vary within the scope of the ensuing claims.
