flushing the vending machine’s water tract
Stop the water supply to the vending machine. Use the suitable container for draining water. To drain
water do the following:
1.
Cool down the boiler. For the purpose enter the service menu and select sub-clause
[1.9.10 Cooling
the boiler]
and start the cooling process by pressing 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 purpose re
-
move 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.
3.
After cooling, flush the boiler. For the purpose enter the service menu and select sub-clause
[1.9.12
Boiler flush]
and start the flushing process 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 display. 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 autono
-
mous 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).
