3.4.11 Autonomous operations, water reservoir and feed pump
а. Water reservoir
By default the vending machines are configured to work with autonomous source of water, which com
-
prises of one or two bottles of water (not supplied with the product). The water bottles are located in the
lower part of the machine behind the waste container (see figure 44 and 45). The maximum volume of
each bottle is 20 litres. The water is drawn using two discharge pipes.
When connecting a new bottle, please put one pipe in each of the water bottles. If you are installing only
one bottle, please insert both pipes into this single bottle (see figure 44).

b. Feed pump
When in autonomous operational mode the pump
draws water from the bottle(s). The feed pump is lo-
cated above the waste container and is fixed to the
rear wall of the machine’s body (see figure 46).

3.4.12 Connection to water supply line (optional)
ATTENTION! The vending machine should be connected to the wa-
ter supply line only by a qualified specialist!
After connecting the machine to the external water supply, you must
reprogram the machine, so as to enable the electromagnetic valve. For
the purpose you must access the technical service menu.
In menu option “1.9.9 Autonomous operations” select NO. The ma-
chine will now shift to operations using external water supply.
To shift the vending machine back to the autonomous water source
mode select YES in menu item “1.9.9 Autonomous operations”.
In this case you must again shift the pipe from the electromagnetic
valve to the feed pump for the autonomous source of water.
The vending machine can operate when connected to autonomous wa-
ter source (as described in section 3.4.11) or when connected to municipal
drinking water supply. The inlet connector to connect the machine with the
water supply line is located on the rear wall of the machine (see figure 47)
and comprises of a ¾” threaded connector.
The water pressure must be in the range of 0.5 to 0.85 MPa. The connec-
tion is made using minimum 6mm pipes, suitable for drinking water. The
pipe must have a G ¾” joint nut. It is recommended to use additional tap
and water filter, installed outside the machine’s body, on water supply line
(not supplied with the product).
Inside the machine’s housing replace the feed pipe from feed pump (au-
tonomous water supply) to electromagnetic valve (see figure 48 and 49).
The valve is regulated by the vending machine control software. It automat-
ically regulates the supply of water into the float chamber.
