2 EQUIPMENT FEATURES
2.1 USE
WO-04 is an equipment designed for dish/glass wash machine water treatment. It is able to modify
organoleptic and chemical characteristics of potable water, reducing saline content.
The machine can preserve water from possible problems that can occur below the aqueducts, such as
infiltrations due to work on the network or breakage, and also from the consequences of keeping water in
decantation basins.
WO-04 is used to supply treated water to dishwasher and glasswesher machines, with frontal load.
The internal pressure tank can supply up to 5lt of treated water with an instant maximum capacity of
15lt/min, at a pressure of 2.5bar.
The treated water capacity is 1.5lt/min; water is stored in the pressure tank to supply high quantity of
water during the rinsing phase of the dish/glass washmachine cycle.
ATTENTION
The water consuption of the dish/glass washmachine installed after the WO-04 must
respect the maximum performance of the system.
All components of the dish/glass washmachine in contact with water must be compatible
with osmosi trated water.
It is forbidden to use brass; all tanks and pipes in stell AISI 304 must be without weldings.
It is racommended to use only plastic parts and stell AISI 316.
The company SMEG. is not responsible of any demage or injury to things or people if
these instructions are not respected.
ATTENTION
WO-04 is not a water purifier.
Using WO-04 to condition water that is not drinkable is ABSOLUTELY PROHIBITED.

From the inlet valve, the water flows to the inlet solenoid valve, on the rear side of the machine, and
then through the prefilter.
After prefiltering, the water is pumped at high pressure to the osmosis vessel with membranes.
The sediment filtration removes suspended solids from water that may damage pump and membranes.
The activated carbon filters facilitate the elimination of the unpleasant chlorine taste, without
compromising the desirable mineral properties of the water. These activated carbon filters can also
absorb potential trace organic micro pollutants, various chemicals organic and inorganic (i.e. chlorine
composites), chlorine residue used to disinfect water, haloforms, pesticides, surface-active agents.
The reverse osmosis phase is the last and most important process that occurs inside the membrane itself.
The water permeates the layer flowing into the collection tubes, and then it is directed to the main tube
of the membrane, wrapped in various layers. The permeate yield comes from the main tube of the
membrane and is sent directly to the permeate outlet.
While the membrane allows the water to filter through, it traps the unwanted concentrated impurities.
The drainage flow is also used to clean the membrane and is directly connected to the drainage system by
plastic brackets.
The mix valve allows the user to choose the hardness or the saltiness of the water produced. The mixer
should be calibrated during the installation phase.
WO-04 permits the treated water to retain about 10 to 15% of the original saline properties.
The machine has a conductivity probe to check water quality on the display.
For the start/stop signal, the machine has a high pressure switch on the permeate line.
For pump safety, the machine has an adjustable minimum pressure switch.
The machine has an auxiliar bypass solenoid valve to supply raw water if water consumption is higher than
the maximum performance of the machine.
ATTENTION
The percentage of dissolved salts and other rejected elements is influenced by the water
quality, temperature, pressure, and total dissolved salts and differs according to the type
of salts or elements.
The treatment of particularly turbid water or water with many impurities can clog the
prefilters and/or membranes, causing a loss in water flow rate.
Reflux water, salt water or water in chemical, physical and bacteriological conditions
that cannot be treated by Reverse Osmosis (industrial reflux or chemical processing)
cannot be treated.

4 FUNCTIONING
4.1 FIRST START UP
ATTENTION
The first start up of the system must be carried out by the installer who will make sure
the machine runs properly.
Insert the feed plug in a 230V 50Hz outlet equipped with efficient grounding. Now the
system is able to work. It advisable to run the run for at least a half an hour before
drinking it, in order to allow the system to eliminate the substances used to conserve the
reverse osmosis membrane.
Make sure there are no leaks in the circuit and fasten the antiflooding probe on the
bottom of the machine.
Close the cover with the screws position the machine in its final destination and push the
brakes of the whells.
Operate sanitation of equipment as described in section 5.8.
The WO-04 membranes are provided saturated in a maintenance solution. Before taking water, let it run
for at least 15-30 minutes.
4.2 NORMAL USE
In order to normally use WO-04 the machine must always be kept on.
The machine starts automatically at every rising cycle of the dish/wash machine. Every six hours the
machine automatically opens the inlet solenoid valve, in this way the membranes are washed for 2
minutes.To adjust the salinity of the water, acting on the valve for mixing later.
If high water consumption occurs, the by-pass solenoid valve opens and raw water flows to the outlet.
ATTENTION
Absolutely avoid letting the membranes dry out; this could irreparably compromise its
functioning.
4.3 INACTIVITY
ATTENTION
It is advisable, each time the machine is inactive for a period over one week, to let the
water run for at least 10 minutes before using it.
It is advisable to sanitize the system every six months during routine maintenance
procedures.
Contact assistance in order to carry out this operation, which must be performed by
specialized personnel/installation technicians.
