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.
