STEAM.Maxi™ plumbing
Plumbing: water supply
Warning
A shut-off valve and a mechanical filter should be positioned between the water mains and the appliance.
The appliance is supplied with 2 metres of piping at the corresponing attachment (3/4") with non-return valve
and mechanical filter, as required by current reglations.
Before connecting the water pipe to the appliance, flush it out with water in order to eliminate any residue
which has accumulated inside it.
The pressure value of the water supply at the inlet should be between 150 and 400 kPa; its temperature must
be no higher than 30°C.
The appliance has an internal pressure reducer which is calibrated to 2 bar, in order to ensure the correct
amount of steam is produced by the STEAM.Maxi™ system, thereby guaranteeing optimal cooking results.
If the pressure of the water supply at the inlet is too low, a pump with a suitable flow rate should be used.
WATER IN
If connection to the water mains is not possible, the steam circuit of the oven can be fitted with the XC665
kit, which draws distilled water from a jerry can or another type of container.
Water supply quality
The water supplied to the STEAM.Maxi™ circuit must have a maximum hardness of 100 μS/cm.
The use of a deioniser (reverse osmosis) is strongly recommended, in order to prevent limescale and/or other
mineral deposits from building up inside the oven.
As such, you may take the opportunity to use the UNOX reverse osmosis system, code XC235, which is directly
controlled by means of a self-diagnosis system implemented by the electronic control panel of the oven.
User recommendations
Any damage caused by limescale or other chemical agents carried by the water is not covered by the
guarantee.
