ty information is observed; this information is set out in the following sections. Some of the tasks may have additional safety infor-
mation which highlights the specific dangers or hazards associated with such work.
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.
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.
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.

2 Transport and packaging
Choose a suitable packaging when returning the dispensing valve itself or one of its components to Cornelius Deutschland GmbH,
e.g. for repairs. In particular, make sure that the dispensing valve and any components are protected from shock/impact, moisture,
dirt and electrostatic discharge (ESD). This will prevent transport damage to the dispensing valve and to the components, for which
the manufacturer shall assume no liability.
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 dispensing valve. This will lead to damage to internal components.
• Before shipment, storage or relocation, the dispensing valve is to be cleaned and the cleaning solution is
to be fully drained from the dispensing valve.
2.1 Storage
Avoid excessive temperature fluctuations as condensate may form, which in turn may cause damage to the dispensing valve or
to its components.
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 dispensing valve, as well as certain weather conditions (e.g. condensate forming in
the dispensing valve, sunlight) will cause damage to the dispensing valve and its components.
• Protect the dispensing valve and its components by storing the dispensing valve in a clean and dry place,
and by ensuring stable ambient conditions.
• If possible, store the dispensing valve in its original packaging. Unpacked dispensing valves must be cov-
ered 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 dispensing valves and/or any electronic components in their original packaging.
• Keep dispensing valves 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.
2.2 Disposal
Disposal of the dispensing valves must be carried out in compliance with the applicable local and/or national and international reg-
ulations. Units must not be disposed of with household waste.
If the dispensing valve 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.

3 Description
The dispensing valve UFB1 offers two fast flow rates, see 3.4. A 3 oz valve with a flow rate of 1.5 – 3 oz/sec (45 – 90 ml/sec) and
a 4 oz valve with a flow rate of 2 – 4 oz/sec (60 – 120 ml/sec) are available. A prerequisite for using the 4 oz valve is the operation
of a base unit designed to refrigerate and convey.
The dispensing valve UFB1 includes a 24 VAC solenoid. The voltage on the coil should be 22 and 27 VAC when the magnet is
energised.
The dispensing valve UFB1 is available in the following designs:
• Dispensing valve UFB1 portion control; see chapter 3.1.1.
• Dispensing valve UFB1 push button; see chapter 3.1.2.
• Dispensing valve UFB1 dispensing lever; see chapter 3.1.3.
• Dispensing valve UFB1 OptiFill; see chapter 3.1.4.
For dispensing valve UFB1, a standard dispensing nozzle and a juice dispensing nozzle are available; see 3.1.5.
With the juice dispensing nozzle, the concentrate flows into the dispensing nozzle from a higher level, resulting in a better mixing
result of the beverage. In addition, the openings in the diffusor are larger to prevent clogging.
Syrups with a high sugar content are more viscous (thicker) than diet syrups and therefore have a higher pressure drop within the
dispensing system.
This pressure drop results in a lower flow rate at the valve.
Increasing the pump pressure at the pressure-reducing valve reduces the increased pressure drop.
NOTICE!
The pump pressure setting for the various syrups can be found in the documentation for the base unit.

3.1.6 Juice dispensing nozzle
This dispensing nozzle is used exclusively for dispensing juice, and comprises the following components:
3.2 Functions within the dispensing system
NOTICE!
The operator manual applicable to the base unit contains the description of how the dispensing valve functions
within a dispensing system.
3.3 How the dispensing valve works
A beverage is dispensed by opening the outlet in the respective dispensing valve.
The valve controller works in accordance with the buttons on the control panels, which are actuated on the respective dispensing
valve, or the dispensing lever.
The syrup or concentrate, as well as the soda, are conducted from the base unit through the block mount into the flow controller,
through the valve head into the dispensing nozzle, where they are mixed. From there, the beverage runs into the cup.
An optional soda lever is available for the dispensing valve UFB1. Actuating the soda lever opens only the soda path in the valve,
so that only soda, without syrup or concentrate, flows through the block mount into the flow controller, through the valve head into
the dispensing nozzle and then into the cup.
3.4 Technical data
NOTICE!
For information on the technical data, please refer to the dispensing valve operator manual; see the document
