2. CHARACTERISTICS OF THE DEVICE

2.1. RECOMMENDED USE

WO-02 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-02 is used to supply treated water to undercounter dishwasher and glasswasher machines with atmospheric boiler “break tank” or similar. If used with a dishwasher without break tank and rinsing pump, an external pressure tank of at least 18 liter must be installed between the osmosis equipment and the dishwasher; air precharge must be approx

2.5 bar. The normal production of the machine is approx 100 liters/hour, with a dishwasher with “break tank”. If an external pressure tank is installed, the normal production reduces to about 70 liters/hour, depending on pressure tank backpressure.

sensory or mental disabilities are reduced, or lack of experience or knowledge, unless they have been granted through the intermediary of a person responsible for their safety, supervision or instruction concerning the use of the device. Children should be supervised to ensure they do not play with the appliance.

The water requirements of the dishwasher installed after the WO-02 must respect the maximum performance of the osmosis equipment.

All components of the dish/glass washmachine in contact with water must be compatible with osmosis trated water.

It is forbidden to use brass; use only plastic parts and stainless steel parts. Basins and tanks in AISI 304 must be without weldings as possible.

It is reccomended the use of parts only in plastic or in stainless steel AISI 316.

The company SMEG is not responsible of any demage or injury to things or people if these instructions are not respected.

WO-02 is not a water purifier. Using WO-02 to condition water that is not drinkable is ABSOLUTELY PROHIBITED.

2.3 COMPONENTS

2.3.

1 Prefilter

The device is supplied with an external PROFINE M BLU carbon block cartridge to ensure chlorine removal and filtration of raw water.

2.3.2 Pump with motor 150W

To increase operating water pressure, it is installed inside the machine a pump mini 200 l/h, leaded by an asynchronous motor.

2.3.3

Membrane

The membranes are the core of the machine; four membranes Filmtec TW30 1812 100gpd are installed.

2.4 DESCRIPTION

There are three external hydraulic connections on the back of the device, respectively, for the inlet water ¾”G, the outlet water ¾”G to the dish/washmachine and the line used for drain off (6mm diameter). On the rearside of the machine, there is also the power cord, and air vents.

It is necessary to install an external prefilter PROfine BLU carbon block medium to ensure chlorine removal and filteration of raw water. The water flows then through the quick connection carbon filter. The carbon block filter facilitates 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.

From the connection to the main plumbing network, the water arrives to the inlet solenoid valve, and with a T fitting to the min pressure switch and then to the pump. The min pressure switch prevents the pump to run dry. In chase of low pressure, alarm is acustic signalled and then the machine makes automatic restart after one minute. When consecutives low pressure alarm occures, the restart delay automatically increases.

Water is then pumped at high pressure by the brass vane pump connected to the liquid cooled motor. The water arrives at high pressure to the vessels contain the reverse osmosis membranes. 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 outlet.

For automatic start/stop of the machine, a check valve and a max pressure switch are installed in the permeate line, before outlet connection.

On the bottom and on the right side of the machine, there are two leakage probes (for vertical and horizontal operating); if leakage occurs the machine stops automatically and makes acustic alarm. The drain must be connected to the drain siphon with the backflow preventer fitting in the package.

The drain capillary is used to set the drain flow and recovery ratio.
