2.0 INSTALLATION AND COMMISSIONING
2.1 INSTALLATION
•Before unpacking unit inspect carton for any damage relating to forklift forks and damage relating to device falling
over or for evidence of top loading.
• Remove carton from device; inspect all external panels for damage .
Warning unit weight
•Shipping 163 kg
• Nett unpacked 140 kg with detergent.

Unit Dimensions
Height Width Depth (mm)
WDS Freestanding Both Sides 1685 605 625
For Freestanding model, please allow sufficient room for servicing purposes. Recommended space
requirements 300mm on either side and 150mm at the rear of the unit.
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 devises 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).

The Machine is 600mm wide and the centre of the trap is 300mm from each side.
FREE STANDING
‘S’ TRAP PIPE POSITIONING FREE STANDING ‘P’ TRAP PIPE POSITIONING
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 machine. 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 unit is positioned 150mm from the
wall. Because this pipe is graded to 5° this
measurement will vary as the unit is installed
closer or further away from the back wall.
Steam Venting
•No external vent pipe work is required as the machine is designed to condensate all visible steam within the
machine.

2.3 PLUMBING
These Installation Guidelines must be followed to ensure the unit will operated as intended.
Installations must be carried out by a qualified and licensed tradesperson.
Service Connections
NOTE: Plumbing connection must comply to AS3500 and Watermark Certified.
Waste connection
•HOT AND COLD WATER CONNECTIONS ARE REQUIRED. The machine can be connected to any normal
mains pressure hot and cold water supply. A back flow prevention air gap is incorporated in the design of the
water tank. Complies to AS 2845.2
•The water supply is to be connected to an isolating valve or cistern stopcock placed approximately 1200mm
from the floor to the right-hand side of the machine. (Preferably not behind the machine)
Cold water: Flow pressure Kpa 100 min 350 max. Temperature 15°- 25°C
Hot water: Flow pressure Kpa 100 min 350 max. Temperature 55°- 60°C
Minimum water flow for 100Kpa 9.377L/min
If inlet water flow pressure is higher than 350 Kpa an inline pressure reducing valve should be fitted.
Soil Line
•Hot water. Discharge temp 75°– 80°C. Soil line to comply to AS3500
•Soil line connection is by a pan collar or other preferred method. If the belled end on the polyethylene moulded
trap is not required it can easily be cut off to provide a straight pipe connection.
•Level the unit by using the flanged screw in legs and if possible maintain approximately 100mm floor clearance
for ease of floor cleaning. We recommend that some of the leg flanges are fixed to the floor via stainless self
tapping screws to prevent sideways movements and damage to services and soil line connections.
•The soil line should protrude from the floor or wall at a minimum of 100mm

2.4 ELECTRICAL
These Installation Guidelines must be followed to ensure the unit will operated as intended.
Installations and service must be carried out by a qualified electrical licensed tradesperson.
Model: WDS 1ph 240V 50Hz 1 ph 20Amp
WDS 3ph 415V 50Hz 3 ph 20Amp
•Units are supplied with 1700mm power supply cord extending from the rear top right hand side of the device for
hard wiring into Mains ISO switch. Position switch approximately 1500mm above floor level
•Mains power ISO switch must be in an accessible position so device can be isolated from mains power during
service.
•We recommend having a 30mA RCD in the mains supply fixed wiring.
•If the supply cord is damaged, it shall be replaced by the manufacturer or its service agent or similarly qualified
person in order to avoid any potential hazard.
2.5 COMMISSIONING
a) Before switching the unit on make sure the UNIT IS LEVEL and WATER TAPS ARE ON. Check that the
DRAIN WASTE is connected.
b) Turn on the power at the isolation switch. Turn on circuit backers inside electrical cover and press the standby
button on the front display. The LCD display will illuminate and go to standby mode.
c) Check that the water tank is filling with cold water and that it has fill to Level 3. Make sure the lid is put back on
water tank.
d) Check that the steam generator tank has filled to the full Level 3. The steam generator will pre heat to 85°C in
standby mode or during cycle.
e) Check that the 5 litre detergent bottle has been fitted. From the menu, run the DETERG/START to purge
detergent through the line to flow sensor. This may need to be done twice if the line is empty on start up. See
5.6
f) Flush approximately 1 litre of water down the steam generator tank overflow pipe. This will fill the ‘S’ Trap at
the hose junction and prevent steam coming back up into the water tank.
g) From the Menu, run Purge Reset three times. Check for any water leaks.
h) Open the door and turn power off at the control. Check racks for freedom of movement. Check that Flush
nozzles rotate freely. Check that all spray nozzles are tight. Turn power back on and close door by pressing
the door button.
i) Select the BEDPAN/URINE cycle and let it run through the cycle. Repeat the same procedure for the URINE
and BOWL cycles.
j) Replace all covers.
Note: DO NOT USE THE DEVICE WITHOUT THE WATER SUPPLY TURNED ON
