2 For your safety
Read and obey the instructions below to prevent possible damage.
2.1 Safety measures
●Only operate your product if all components are installed properly.
●Obey the local regulations on drinking water protection, accident prevention and
occupational safety.
●Do not make any changes, alterations, extensions or program changes on your
product.
●Only use genuine spare parts for maintenance or repair. If unsuitable spare parts
are used, the warranty for the device will be void.
●Comply with the maintenance intervals (refer to chapter 8.2). Failure to comply can
result in microbiological contamination of your drinking water system.
2.1.1 Danger due to carbon dioxide (CO2gas)
●CO2gas is a non-combustible, non-corrosive, colourless and odourless gas that is
non-hazardous to water.
●It is one and a half times heavier than air and might accumulate close to the floor
or in low-lying parts of a building when released. CO2gas is classified as inert
(under normal conditions, no chemical reaction with other substances).
●Elevated CO2concentrations can occur in case of larger accumulations in enclosed
spaces.
●Higher CO2concentrations lead to health problems, even despite sufficient oxygen
levels, and there is a risk of asphyxiation.
2.1.2 Mechanical hazards
●You must never remove, bridge, or otherwise tamper with safety equipment.
●For all work on the device that cannot be carried out from the ground, use stable,
safe and self-standing climbing aids.
●Make sure that the device is set up in a way that it cannot tip over and that the
stability of the device is guaranteed at all times.

For your safety
9 | 92
BA_100238400000_en_234_SODA JET III.docx
2.1.3 Pressure-related hazards
●Components may be under pressure. Risk of injuries and damage to property due
to escaping water and unexpected movement of components. Check the pressure
lines for leaks at regular intervals.
●Components of the SODA JET III are under pressure. Do not loosen or remove
components which are under operating pressure.
●Make sure that all system components concerned are depressurised before
starting any repair and maintenance work.
2.1.4 Electrical hazards
In case of contact with live components, there is an immediate risk of death due to electric
shock. Damage to insulation or individual components can be life-threatening.
●Only have qualified electricians carry out electrical work on the device.
●If live components are damaged, immediately switch off the power supply and
arrange for repair.
●Switch off the supply voltage before working on electrical system parts. Discharge
residual voltage.
●Never bridge electrical fuses. Do not disable fuses. Observe the correct current
ratings when replacing fuses.
●Keep moisture away from live parts. Moisture can cause short-circuits.
2.1.5 Groups of persons in need of protection
●Children must not play with the product.
●This product can be used by children over 8 years of age and persons with limited
abilities or lack of experience if they are supervised or instructed in the safe use of
the product and understand the resulting hazards.
●Cleaning and maintenance must not be carried out by children.

2.2 Product-specific safety instructions
2.2.1 Handling CO2cylinders (compressed gas cylinders)
The installation of compressed gas cylinders must be carried out by qualified specialists
only.
The safety instructions and requirements for the operation of compressed gas cylinders
must be strictly adhered to (refer to operating instructions order no. 156 959).
DANGER
Risk of explosion
●In case of overpressure, the compressed gas cylinder can explode.
►Place the compressed gas cylinder in an upright position and secure it against
tipping over.
►Always connect the compressed gas cylinder to the pressure reducer with safety
valve.
►Regularly check the connections for leaks and damage.
DANGER
Risk of asphyxiation from carbon dioxide (CO2)
●In case of damage, gas can escape.
►Check that the prerequisites below are fulfilled:
•The installation site must have a minimum room size in m³ = 17 x filling
volume of a CO2cylinder in kg
Example 187 m³ for a 10 kg CO2cylinder (e.g. 75 m2x 2,5 m) and 112 m³ for
a 6 kg CO2cylinder (e.g. 45 m2x 2,5 m).
•Alternatively, a monitored technical ventilation system with an adequate
delivery rate of at least 2x/h must be available.
•If this is not possible, a gas warning system for CO2/lack of oxygen must be
installed to protect the installation room.
Prerequisites when handling compressed gas cylinders
●When connected, store compressed gas cylinders in an upright position only and
secure them with the mounting bracket. Do not throw compressed gas cylinders or
tilt them.
●Store compressed gas cylinders in a cool, well-ventilated place.
●Protect compressed gas cylinders from heat and direct sunlight.
●Keep them at a minimum distance of 500 mm to radiators or other heat sources.
2.2.2 Safety devices

3.3 Functional description
The drinking water dispenser is connected to the cold water network of the domestic drinking
water system.
In a cooling unit, the incoming drinking water is cooled to the desired temperature.
By means of the carbonator, the water of the CLASSIC path is enriched with CO2. At an
average carbon dioxide input (CLASSIC and MEDIUM), At an average carbon dioxide input
(CLASSIC and MEDIUM), the connected CO2cylinder (containing approx. 10 kg of food
carbon dioxide) can charge approximately 1500 l of water with CO2.
The solubility of the CO2is determined by the set operating parameters. The CO2
concentration mainly depends on the water pressure, the CO2pressure and the temperature.
The device can dispense three different types of water:
●STILL (refrigerated water)
●MEDIUM (cool and slightly sparkling)
●CLASSIC (cool and highly sparkling)
Depending on which button is being pressed, the corresponding solenoid valves of the
dispenser unit open during tapping.
The occurring dripping water is either collected in an integrated dripping water container with
float switch or is discharged via an optional drain connection.
When the dripping water container is full, no more water can be dispensed. Only after the
water has been disposed of, the drinking water dispenser SODA JET III will be resuming
operation.
3.4 Accessories
Your product can be retrofitted with accessories. Please contact your local Grünbeck
representative or Grünbeck’s headquarters in Hoechstaedt/Germany for details.
