Visually inspecting the unit
NOTICE!
Working with a shut off water pipe means the python and the carbonator
tank will be empty and therefore not dispense. The soda circuit requires
careful bleeding using the carbonator tank drain valve.
1. Check the water level gauge to make sure the water pan is filled up with tap water.
Make sure the water level is between minimum and maximum.
If necessary, fill up the water bath with tap water.
2. Check that the CO
2
bottle valve is open; see documentation on the CO
2
system.
If necessary, open the valve on the CO
2
bottle.
3. Check the pressure-reducing valve on the CO
2
bottle to make sure CO
2
pressure for car-
bonation is set as specified (for the setpoint, see chapter 3.3).
4.
Only for types with CO
2
-operated syrup pumps:
Check the second pressure-reducing
valve on the CO
2
bottle to make sure the CO
2
pressure for pressurising the syrup pumps
is set as specified (for the setpoint, see chapter 3.3).
5. Check that the CO
2
shut off valves are open; see documentation on the CO
2
system.
If necessary, open the CO
2
shut off valves.
6. Check that the water supply valve is open; see documentation on the water supply valve.
If necessary, open the water supply valve.
7. Check the pressure-reducing valve on the water pip to make sure the water pressure is
set as specified (for the setpoint, see chapter 3.3).
8. Check the fill level and the connection of the syrup containers and BIBs and replace the
empty containers with full ones; see chapter 4.2.
9. Check the tightness of the basic ingredient/beverage tubes for any leaks. They can only
be visually inspected.
If there are any fluids leaking out, please inform your service partner.
10. Check the tightness of the CO
2
tubes by closing the valve on the CO
2
bottle.
The initial pressure indicator on the pressure-reducing valve must not drop; if it does, in-
form your service partner immediately!
11. Afterwards, open the CO
2
bottle valve again.
12. Inspect the unit for damage.
Always replace any damaged components and parts.
Please contact your service partner.
13. Check that the supply and exhaust air grilles are clean and that there is a proper air flow.
Dirty or blocked supply and exhaust air grilles are to be cleaned; see chapter 5.3.
14. Check the legibility of the warning signs; see chapter 3.3.7.
Always replace any missing or illegible warning signs. Please contact your service partner.
