MODELS WITHOUT BOILER – WTS GRAPH B (in case of treatment, check the treated water parameters falling into the green
area; in no cases the values have to fall into the grey area)
General advices
• Periodical maintenance of the water treatment devices avoids compromising appliance operation and prevents risk of corrosion.
• To prevent damaging the appliance, at every periodical regeneration of the water softener filter, do a filter wash cycle without
introducing water into the oven.
IMPORTANT
The manufacturer declines any liability in case of incorrect maintenance.
CAUTION
Do not use dispensers of substances for preventing scale in the pipes (e.g. polyphosphate), they
can compromise correct appliance operation.
F.7.2 Check supply pressure
The pressure upstream of the oven must be 100 – 450 kPa
(1,0 – 4,5 bar / 14,5 – 65 psi).
NOTE!
If the water pressure of the system supply is higher
than 4.5 bar, it is recommend to install a water
pressure regulator.
Measure the pressure in dynamic conditions, i. e. during the
boiler filling and/or washing phase and at a temperature of 30
℃ /86 ℉ .
• The water flow rate for CWI1 is min 2 l/min – max 10 l/min.
• The water flow rate for CWI2 (treated water) is min 2,95 l/
min – max 5.75 l/min.
F.7.3 Water draining system
• The oven has an AIR-BREAK, anti-backflow device inside
that allows to prevent any backflow from the drainage
system
entering the internal pipes and the oven
compartment.
Therefore, to connect the draining system it is possible:
– to connect the drain pipe directly to the drainage system:
– or to let the drain pipe discharge into a floor grate.
