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.

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 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.

2.3 Plumbing
These installation guidelines must be followed to ensure the device will operate as intended
Installations must be carried out by a qualified, licensed tradesperson
Service Connections
NOTE: Plumbing connection must comply with AS3500 and be Watermark Certified
Waste connection
HOT AND COLD WATER CONNECTIONS ARE REQUIRED. The device 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 device (preferably not behind the device)
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 must 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 device by using the flanged screw in legs and if possible maintain approx. 100mm floor clearance for ease of
floor cleaning. Malmet recommends affixing some of the leg flanges 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 device will operate as intended
Installations and service must be carried out by a qualified, licensed electrical tradesperson
Model: WDS 1ph 240V 50Hz 1 ph 20Amp
WDS 3ph 415V 50Hz 3 ph 20Amp
Devices 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 approx. 1500mm above floor level
Mains power ISO switch must be in an accessible position so device can be isolated from mains power during service
Malmet recommends 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 on the device make sure the DEVICE 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 breakers 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. Ensure 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 preheat 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 (see 5.5). 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
