1.2. Water characteristics
The appliance must be supplied with drinking water having the characteristics shown in the
table. If these characteristics are not complied with, the appliance might suffer damage; a
water treatment device should therefore be installed.

1.3. Instruction to reduce width
FX61, FX101
The smallest dimension (depth) of the 61-101 models is about 900mm.
It is possible to reduce it by:
Option A - 20mm - removing the T protection from the oven drain.
Option B - 66mm - removing the T-protection from the oven drain, the T-pipe from the
drain and the cooling fan protection at the back.
Option C - 56mm - disassembling the handle / lock assembly and handle.
By combining options B and C the minimum oven measurement is approximately 778mm.
FX82, FX122
The smallest dimension (depth) of models 82-122 is about 1093mm. It is possible to
reduce it by:
Option A - 20mm - removing the T protection from the oven drain.
Option B - 68mm - removing the T-protection from the oven drain, the T-pipe from the
drain and the cooling fan protection at the back.
Option C - 56mm - disassembling the handle / lock assembly and handle.
By combining options B and C the minimum oven measurement is approximately 970mm.
Option D (valid only for FX82) - As follows:
- disassemble the oven body from the support (the screws to be removed are at the top of
the 4 uprights and on the inside of the base where the two support bars are).
- lift the oven body and make it pass through the narrower part.
- Reassemble the oven body on the support.
The minimum oven measurement possible is about 905mm.

FX201
The smallest dimension (depth) of the 201 model is about 920mm. It is possible to reduce
it by:
Option A - 18mm - removing the T protection from the oven drain.
Option B - 68mm - removing the T-protection from the oven drain, the T-pipe from the
drain and the cooling fan protection at the back.
Option C - 15 mm - disassembling only the handle.
By combining options B and C the minimum oven measurement is approximately 837mm.
FX202
The smallest dimension (depth) of model 202 is about 1104mm. It is possible to reduce it
by:
Option A - 18 mm - removing the T protection from the oven drain.
Option B - 68 mm - removing the T-protection from the oven drain, the T-pipe from the
drain and the cooling fan protection at the back.
Option C - 15 mm - disassembling only the handle.
By combining options B and C the minimum oven measurement is approximately 837mm.

The system works in two distinct ways depending on whether the motorised valve is
opened or closed.
2.1. Open valve operation
The rotation of the fan creates a vacuum effect in the local area behind his disk back
where it faces the suction pipe/exhaust 5. When the butterfly valve 7 is open to this effect
a vacuum sucking air flow entering through the pipe 5. Simultaneously the moist air inside
the cooking chamber is induced to leave through the vent tube 6, aided by a flow diverter
(not shown) placed inside the chamber at the exit hole. Through the injector 12 is sprayed
water into the vent pipe - especially at high temperatures - in order to cool and condense
the flow of moist air coming out. The condensate is collected on the bottom of the pipe to
siphon 6 and conveyed through the rubber hose 14.

2.2. Closed valve operation
With the valve closed, the steam can’t escape from the vent pipe 6, or from the tube 5 at
least until the pressure inside the cooking chamber is not sufficient to overcome the effect
of decompression generated by the rotation of the fan (usually 1,5-2,0mBar). But when the
pressure chamber exceeds the decompression generated by the fan, the steam excess is
expelled through the tube 5. The system operates as a closed system, where the
overpressure valve (overpressure valve in the FM ovens) is dynamically replaced by the
effect of decompression generated by the fan. Even in this mode, water is sprayed by the
injector 12 in order to maintain the siphon full.
Note that, unlike than the FM, the condensate tube 14 is connected upstream of the swing
of the siphon, as with the motorised valve closed the vent pipe 6 and the drain tube 14 are
at the same pressure of the cooking chamber.

The two modes of operation described above are used in different modes of cooking in the
following way:
Convection cooking: means the user can determine the % the vent valve is open
according to the diagram below.
0% - vent completely open (bar on the display all red)
from 10 to 90% - the valve opens and closes in timed mode, the value shown on the
display is the % of time that remains closed.
100% - vent completely closed (bar on the display all grey)
Combi cooking mode: the user can set the desired % of steam - the opening and closing
of the vent valve is controlled automatically by the oven, based on values detected from
the opposite humidity probe.
Steam cooking: valve remains closed.

2.3. Drain cooldown / steam condensing operation
The inlet water assembly 11 feeds the cooling water injector 12. The opening of the water
solenoid valve is timed based on the mode of operation (convection, combi or steam),
chamber temperature and the temperature detected by temperature sensor 9.
The inlet water assembly 11 is different depending on the levels:
Level 3
It consists of:
- Non return valve EN1717 (for washing)
- Pressure reducer (for washing)
- Double water solenoid valve (one is for washing)
- Pressure switch on the drain cooldown line
- Pressure switch and manometer on the washing water line
Note: the water pressure adjustment should be done during a washing cycle.
Level 2
It consists of:
- Double water solenoid valve (one is for cleaning)
- Pressure switch on the drain cooldown line
- Pressure switch on the washing water line (not for BX MY2016)
- Pressure reducer (only models FX201-202)
Level 1
It consists of:
- Single water solenoid valve
