ature as is set in the machine’s configurations.
The boiler in the machine is placed in the rear section of
the vending machine’s body (see fig.5.11). To access the
boiler, remove the vending machine’s rear panel. To
avoid injuries connected with “accidental release of stored
energy” and/or “steam burning effect”, the boiler has hard
-
ware protection from the pressure, exceeding the working
pressure maximum range. The excess water heated by the
boiler is rejected to the liquid wastes container via the water
valves located at the boiler case.
DANGER Of BURNS!

Steam boiler (fRESH MILK option)
The steam boiler is installed in the vending machines with FRESH MILK option only. It’s intended for
heating the water to make steam, which is needed for milk foaming.
The steam boiler is installed in the rear hydraulic unit compartment of the vending machine (see fig.
5.11). To access the steam boiler remove the vending machine case rear wall.
To avoid injuries associated with “accidental release of stored energy” and/or “steam burning effect”,
the steam boiler has hardware protection from the pressure, exceeding the working pressure maximum
range. The excess steam, heated by the boiler, is rejected to the liquid wastes container via the emer
-
gency valve located at the steam boiler case.
The boiler has nonseparable structure. In the case of boiler breakage and/or the internal fuse blowing
the boiler should be completely replaced. After the boiler replacement, the boiler sensor gaskets and fit
-
tings should be visually inspected. This operation is conducted to prevent emergency situations, caused
by bad boiler repair.
