Buildings
Service connections are usually pre-placed after planning and consultation with all interested parties. Installation is by
connection to the services provided
As the soil line (sewerage outlet) is the least flexible of all the connections, this usually influences the decision as to where
to place the WDS. If an existing soil line can be utilised this will represent a cost saving
The WDS is supplied with either an ‘S’ or ‘P’ Trap as nominated by the Purchaser. The ‘S’ Trap connects through the floor
and the ‘P’ Trap connects through the back wall. The trap section is easily removed if the wrong trap has been ordered.
Refer to Diagram C2 for trap connections.
Potential electromagnetic or other interference between other EQUIPMENT and other devices can possibly affect the
infra-red hands free operation sensor. It is advisable to check all the equipment and devices in the intended installation
area that have infra-red operation. Electromagnetic interference can be prevented by installing the device in non patient
areas of hospital (or similar)

For reasonable connection working space allow 150-200mm from rear of device to wall.
The device is 600mm wide and the centre of the trap is 300mm from each side.

The centre of the soil line to receive the ‘S’ Trap
should be approximately 272mm from the back wall.
To allow for normal recommended minimum side
service access, space soil line 600/700mm from side
wall.
If space restrictions do not allow for recommended
side service access, we suggest preference be given
to providing the most space available on the right
hand side as you look at the front of the device.
This will ease any difficulty in servicing the steam
tank element and probe.
The centre of the soil line to receive the ‘P’ Trap
should be approximately 410mm from the floor
when the device is positioned 150mm from the wall.
Because this pipe is graded to 5° this measurement
will vary as the device is installed closer or further
away from the back wall.
Steam Venting
No external vent pipe work is required as the device is designed to condensate all visible steam internally.
