1Safety
1.1 Intended use
By using the unit as intended you will not only protect yourself, but also prevent damage occurring to the unit and its components!
You can find further information about the intended use of the unit in the tower operator manual, document no. TD0004000.
1.2 Improper use
Improper use of the unit and unauthorised modifications to the unit and its components may cause personal injury and equipment
damage for which Cornelius Deutschland GmbH shall assume no liability. Improper use of the unit is prohibited.
You can find further information about the improper use of the unit – and the meaning of improper use – in the tower operator
manual, document no. TD0004000.
1.3 Staff
There is a clear definition as to what group of people is permitted to carry out what type of work on the unit. You can find further
information about who is authorised to carry out what type of work on the unit in the tower operator manual, document no.
TD0004000.
1.4 Presentation of warnings
The documents supplied with the unit provide warnings regarding any dangers or hazards that might exist. You can find more in-
formation about the design and presentation of warnings in the tower operator manual, document no. TD0004000.
1.5 Safety information
1.5.1 Safety information to prevent personal injury and equipment damage
Any work on the unit and its components which goes beyond operation and beyond the servicing and maintenance tasks that the
operator is authorised for, may only be performed by experts (for a definition of experts, see the tower operator manual, document
no. TD0004000). Furthermore, it is crucial that when performing work on the unit all safety information is observed; this information
is set out in the following sections. Some of the tasks may have additional safety information which highlights the specific dangers
or hazards associated with such work.
1.5.2 Safety information for using electrical assemblies
DANGER!
To prevent risks to health and safety, please always observe the following five safety rules:
These five safety rules are to be applied before carrying out work on the electrical system and in the order stated
below. Once work is completed, the safety rules are to be undone again in reverse order.
• 1. Disconnect from power.
• 2. Secure against reconnection.
• 3. Check that the system is disconnected from power.
• 4. Ground and short-circuit the system.
• 5. Cover or separate adjacent live parts.
WARNING!
Risk of burns when touching hot parts of the unit!
Touching parts of the unit after it has been in continuous use over an extended period of time will result in a risk
of burns.
• Take appropriate safeguard measures, such as by wearing heat-resistant protective gloves.
NOTICE!
• Make sure that the cable markers are not removed from the cables and/or mark or label the cables such
that they can be correctly assigned during installation.
ATTENTION!
Cables must be fixed in place using cable ties.
When fixing cables in place using cable ties, observe the following points:
• Once work on the unit is completed, return the area to the same state that you found it in.
• Using cable ties, combines cables in a meaningful way.
• When installing cables, be mindful of any bending radiuses that the manufacturer may have specified.
• To fix cables in place using cable ties, use the mounting bases provided.

2 Transport and packaging
Choose a suitable packaging when returning the unit itself or one of its components to Cornelius Deutschland GmbH, e.g. for re-
pairs. In particular, make sure that the unit and any components are protected from shock/impact, moisture, dirt and electrostatic
discharge (ESD). This will prevent transport damage to the unit and to the components, for which the manufacturer shall assume
no liability.
2.1 Storage
Avoid excessive temperature fluctuations as condensate may form, which in turn may cause damage to the unit or to the compo-
nents.
The permissible storage temperature is -10 °C to +50 °C.
The acclimatisation period is 6 hours.
ATTENTION!
Damage due to improper storage!
Dirt or moisture entering a unit, as well as certain weather conditions (e.g. condensate forming in the unit, sun-
light) will cause damage to the unit and its components.
• Protect the unit and its components by storing the unit in a clean and dry place, and by ensuring stable
ambient conditions.
• If possible, store the unit in its original packaging. Unpacked units must be covered with a dustproof cover.
No condensate must form under the cover.
ATTENTION!
Risk of electrostatic charge!
Improper handling or storage may result in electrostatic charges.
• If possible, store units and/or any electronic components in their original packaging.
• Keep units and/or electronic components away from charged objects, fields and insulators.
• Avoid electrostatic charges when removing packaging and/or handling electronic assemblies and compo-
nents by working at an ESD-protected workstation or work area.
• When working at the unit or its components, wear a grounding (antistatic) wrist strap at the very least and
wear antistatic gloves if necessary.
ATTENTION!
Component damage due to material ageing!
Material can age due to long storage periods, thereby affecting the material’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.
2.2 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 regulations. 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 atmosphere.

6.2 Cleaning the tubes and valves
5. Fill the cleaning container with a suitable disinfectant solution.
- For syrup tubes: TM DesanaMax fp.
- For water lines: either TM Desanacid fp or hydrogen peroxide.
6. Vent the carbonator tank; see the document “Undercounter cooler installation and service manual”.
7. Rinse all tubes with the disinfectant solution, one after the other, by requesting a beverage from the respective dispensing
valve; see dispensing valve documentation.
- Continue requesting a beverage for the syrup tubes until you can see the disinfectant solution, recognisable by its dye,
coming out of the dispensing valve.
- Using TM Desanacid fp as a disinfectant for the water lines, continue requesting a beverage until you can see the disin-
fectant solution, recognisable by its dye, coming out of the dispensing valve.
- Using hydrogen peroxide as a disinfectant for the water lines, continue requesting a beverage until you can determine
hydrogen peroxide levels using a test strip.
Make sure that the tubes remain exposed to the disinfectant solution for a minimum of 15 minutes.
You can only continue to the next step if and when all tubes have been rinsed with the disinfectant solution.
In the next step, the tubes will be rinsed with clear water.
8. Depressurise the cleaning container and the tubes by using the pressure relief valve on the cleaning container.
9. Fill the cleaning container with clear water.
