. Start the cooling process by press-
ing the OK button. After you start the process the machine will pump sufficient amount of water
through the boiler to cool it down to 45 degrees. This process can be executed for machines with
external water supply as well as for machines with internal water cans.
2. After the boiler has been cooled the machine’s display shows the
OK
sign, after which you
should-disconnect the machine from water supply or you should remove the water supply pipes
from the cans/bottles. It is also necessary to flush water from the pipe, which supplies water from
external water supply valve or autonomous water supply pump, to the float chamber. For the pur
-
pose remove the pipe from the valve or pump and direct it to the flush bucket. Make sure that all
the water from the pipe is discharged.

by pressing the OK button. The machine will start pumping out water from the float chamber and
the rest of the water tract, which supplies water to the boiler.
4. When the given process will be completed, you will see the OK sign on the touch screen. This is
when you should turn the machine OFF.
5. Place a container under the boiler and remove the pipe from the bottom of the boiler by loosening
the fixator screw. Then turn the machine ON and wait until all the water would be flushed from the
boiler (until the water stops dripping).
6. Turn OFF the vending machine.
7. Reconnect the pipe to the boiler with the help of the tightening screw.
NOTE:
when using internal water supply from cans/bottles it is also necessary to flush the au
-
tonomous function pump. for the purpose, following the cooling process and removal of supply
pipe from the pump, it is necessary to manually pull down the float from the float chamber until the
pump starts and hold the float for 5-10 seconds. After this you must reinstall the pipe (to the valve
or the pump).
