DANGER!
Risk of personal injury and equipment damage due to leaking refrig-
erant!
In accordance with DIN EN 378 standard, part 1, the refrigerant used with
this unit, R290 (propane), is classified as safety group A3. It is not poison-
ous and not caustic or corrosive. However, it is combustible and highly
flammable. As a result, a potentially explosive atmosphere may occur in the
case of leaks. The refrigerant is heavier than air and, consequently, accu-
mulates at the bottom and may enter lower lying areas (e.g. sewage sys-
tems). At high concentrations, this may lead to a lack of oxygen, resulting
in a risk of suffocation. Lower concentrations may have a narcotic effect.
The refrigerant has a very slight, somewhat sweet smell.
• Avoid any damage to components that carry the refrigerant.
• If you suspect any leaks, however small, shut down the unit, air the
room well and inform your service partner.
• Do not allow direct contact with the skin of any leaking refrigerant.
• Fire, open flames and smoking are prohibited.
• If you begin to notice any smell, leave the room and alert the fire ser-
vice.
NOTICE!
In particular, safety standards are to be observed in their scope of validity
(e.g. EN 60335-2-75).

ATTENTION!
Component damage due to material ageing!
Material can age due to long storage periods, thereby affecting the materi-
al’s properties (e.g. plastics and seals may become brittle). The properties
of lubricants may change due to long storage periods.
• Check the assemblies and components for damage before each use/
before installing them. Do not install assemblies or components that
show visible signs of ageing.
ATTENTION!
Component damage due to freezing liquids!
Ambient temperatures that are below freezing will lead to the freezing of
any water or cleaning agent residue remaining inside the unit. This will lead
to damage to internal components.
• Before shipment, storage or relocation of the unit, the unit is to be
cleaned and the cleaning solution is to be fully drained from the unit.
2.3 Disposal
Disposal of the units must be carried out in compliance with the applicable local and/or national
and international regulations. Units must not be disposed of with household waste.
If the unit contains fuels or lubricants in liquid, paste-like or gaseous form, such as oil, grease,
cooling agents etc., such fuels or lubricants are to be collected using appropriate measures
and disposed of in compliance with the applicable local and/or national and international reg-
ulations. Such fuels or lubricants must always be prevented from seeping into the ground, the
sewage system and any bodies of water, and must always be prevented from entering the at-
mosphere.

3.2 Functions within the dispensing system
The unit refrigerates and conveys non-alcoholic drinks from the storage section of the dispens-
ing system to the tower on the counter. The pressure-reduced, filtered water, syrup, and CO2
required is supplied as illustrated in the flowchart (Fig. 2).
Fig. 2
The beverage components are chilled to the right temperature in the housing. Drinking water
is also carbonated. This means that still water, soda and chilled syrup are available at the re-
frigerator outlets for postmix beverages.
When requested at the tower, they are conveyed to the tower via the python. Only the soda is
continuously circulated.
CO2 or electrically operated syrup pumps are used to convey the brands (syrup).
