1. general purpose

All products in the SILEXA product line and the alternative POS system solutions (TiPOS) from the Redl Group are designed exclusively for use in commercial catering businesses and comparable corporate environments (hotels, company catering, events, retail).

The systems are used to control, monitor, evaluate and optimize dispensing and serving processes. They are to be treated as professional operating resources.

1.1 Intended use cases

✔ Permitted use – all products

  • Use exclusively in commercially used premises by trained specialist personnel.
  • Operation in accordance with the enclosed technical specifications and installation instructions.
  • Only connect to tested and standardized supply systems (electricity, gas, water, compressed air).
  • Maintenance and cleaning in accordance with the product-specific interval specifications.
  • Use within the specified ambient conditions (temperature, humidity, room climate).
  • Use only with consumables and accessories approved by the manufacturer.

1.2 Non-intended use

✘ Prohibited use – all products

  • Use by unskilled or untrained persons.
  • Operation outside the parameters specified in the technical data.
  • Modifications, conversions or extensions without the express written permission of the Redl Group.
  • Use in potentially explosive atmospheres, unless the product is expressly certified for this purpose.
  • Use for media that are not approved for the respective system.
  • Operation with damaged components, defective cables or open housing.

2. general safety instructions

2.1 Electrical safety

  • All devices must be electrically checked by a specialist before commissioning.
  • The connection must be carried out exclusively by specialist companies.
  • In the event of moisture or damage to the mains cable, disconnect from the mains immediately.
  • Overvoltage protection in accordance with national standards must be ensured.
  • Disconnect the power supply before carrying out any maintenance work on the electrical system.
  • No unauthorized interventions in electrical assemblies.

2.2 Pneumatic systems (compressed gas CO₂/N₂ and compressed air)

Several products in the SILEXA product line work with compressed gas (CO₂, N₂) and/or compressed air. The following safety regulations are mandatory for all pneumatic systems:

⚠ CAUTION - Pneumatic systems: NEVER change pressures without authorization!

The set operating pressures are specified by the manufacturer or specialist company – do not adjust them yourself!

  • Excessive pressure can lead to line breakage, valve failure or serious injury.
  • Regular visual inspection of all hoses, fittings and connections for leaks.
  • CO₂ and N₂ are odorless gases – only operate in sufficiently ventilated rooms (see risk assessment) or with a suitable gas warning system.
  • In the event of a gas leak, leave the room immediately, ventilate and inform a service partner or qualified person.
  • Always secure pressurized gas cylinders against falling over and keep them away from heat sources.
  • Permissible operating pressures are specified in the respective product data sheets.
  • Only have pressure reducers adjusted and maintained by trained specialists.

🔧 Air Compressor – Operator’s Maintenance Obligations

  • The air compressor used must be maintained in accordance with the operating instructions supplied by the compressor manufacturer.
  • Maintenance of the compressor (filter change, condensation drain, pressure test, oil level, etc.) is the responsibility of the operator.
  • Observe and document maintenance intervals and protocols in accordance with the operating instructions.
  • Compressed air must be free of oil and water vapor – if necessary, install suitable filters upstream.
  • Immediately take defective or unmaintained compressors out of operation.

Special note: Pneumatic cylinders

⚠ DANGER - Pneumatic cylinders: Risk of injury from incorrect pressures!

The following products use pneumatic cylinders to open taps and valves:

  • SILEXA Growler Filler – pneumatic filling cylinder
  • SILEXA Move Add-On (tower with pneumatic beer tap) – pneumatic dispensing cylinder may only be operated with compressed air, not with dispensing gases.

The following dangers exist if the pressures are not set correctly:

  • Excessive pressure: The cylinder extends uncontrollably and with great force – crushing hazard for fingers and hands!
  • Pressure too low: The tap does not open fully – system malfunction.
  • Pressures may ONLY be set by trained specialist personnel or Redl service technicians.
  • Never reach into the movement area of the cylinder during operation.
  • Before carrying out maintenance work on pneumatic cylinders: Shut off the compressed air supply completely and release the pressure.

2.3 Use of technical gases (CO2, N2, mixed gas, etc.):

⚠ DANGER - Technical gases: Risk of suffocation!

As a rule, technical gases are used in many technical systems in such a way that they are not released into the surrounding atmosphere during normal operation. Examples of this are gases that are used as refrigerants in cooling systems or as dispensing gases (in shipping containers), such as carbon dioxide CO2 and/or nitrogen N2. These gases can be released after incidents and accidents (e.g. collisions), technical failure or after assembly errors (changing cylinders) and endanger the safety and health of workers.

  • The responsibility for suitable protective measures and the safeguarding of hazardous areas lies exclusively with the operator.
  • In the event of damage, the Redl Group and its affiliated companies shall be indemnified and held harmless.
  • The requirements are described in the decree “Unintentional release of technical gases in rooms” GZ: BMASK-461.308/0011-VII/A/2/2015.

On request, we will carry out a risk assessment by an expertly trained person and, if required, prepare a separate quotation for the use of a SILEXA Gas Alarm Systems gas warning system.

2.4 Food hygiene and cleaning

As all dispensing products come into contact with food, the relevant national and European food hygiene regulations (in particular Regulation (EC) No. 852/2004) apply.

Hygiene & cleaning

Obligation to inspect: every operator of a fixed or mobile beverage dispensers is obliged under the Occupational Health and Safety Act and the Ordinance on Industrial Safety and Health to carry out a risk assessment, an inspection after assembly/installation and, if necessary, a periodic inspection.

Documentation obligation: written records of risk assessments and inspections must be kept at the operating site of the system. (See § 3, § 10 and § 11 of the Ordinance on Industrial Safety and Health and § 2 para. 1 of the accident prevention regulation BGV A 1- Principles of Prevention. The EU Regulation on the hygiene of foodstuffs (Regulation (EC) 852/2004) also prescribes corresponding documentation (see Article 4 (2) (g)).

  • Observe cleaning intervals in accordance with product regulations and local food authority requirements.
  • Only use approved, food-safe cleaning agents and disinfectants.
  • After cleaning, rinse all components completely to remove cleaning agent residues (pH check).
  • Document proof of cleaning (date, agent, person carrying out the cleaning).
  • Check dispensing hoses and lines regularly for biofilm formation.
  • Replace dispensing heads, filters and cooling elements according to the maintenance schedule.

Automatic cleaning systems - pH value control absolutely essential!

⚠ SILEXA Draft Line Cleaner - pH check after EVERY cleaning!

  • After each cleaning process with the automatic cleaning system, all cleaned pipes MUST be checked for the correct pH value.
  • Only a suitable pH measuring strip (in accordance with the product instructions) should be used for this purpose.
  • The system may ONLY be put back into operation if the measured pH value is within the permissible range specified in the operating instructions.
  • Residual cleaning agent in the pipes can lead to damage to the health of guests and to considerable liability risks for the operator.
  • Document the measurement and result (date, line, measured value, name of the person carrying out the measurement).
  • If the pH value is too high or too low: repeat the rinsing process and measure again.
  • Commissioning without a successful pH check is not permitted.

Special note: Cleaning the pneumatic beer tap

⚠ Beer tap cleaning - Critical for proper function!

  • SILEXA Move Add-On and all products with a pneumatic beer tap must be cleaned regularly.
  • Clogging due to beer or yeast cleaning residues means that the tap will NOT open!
  • Symptom: Device is ready for operation, but no beer is flowing (no error on the controller).
  • Cleaning: Dismantle the tap, rinse thoroughly with lukewarm water, clean the valve seat.
  • Recommended cleaning interval: daily for evening/high-frequency operation, at least twice a week.
  • Do not use limescale or aggressive cleaning agents directly on pneumatic valves.

2.5 Cooling systems and temperature control

🌡 Cooling & Temperature Control

  • Do not block or cover cooling systems – ensure sufficient air circulation.
  • Check the condensate drain regularly and keep it clear.
  • Document product temperatures in the beverage area in accordance with the HACCP plan.
  • Do not introduce any foreign bodies into the cooling housing.
  • If ice forms outside the cooling area, take the appliance out of operation and contact a service partner.

3. legal restrictions - calibration and measuring instrument law

The following regulations must be observed for the proper operation of all dispensing and monitoring systems.

3.1 Purpose and use cases of the flow meters and monitoring systems

All SILEXA systems in waiter service mode are developed as internal control and management systems – including SILEXA Draft Line Tracker and SILEXA Draft Line Counter, for example. They enable:

  • The target/actual comparison between the quantity actually tapped and the sales recorded in the POS system.
  • Avoiding losses due to spillage, theft and shrinkage.
  • Quality control and transparency in dispensing management.
  • Business optimization through evaluation of beverage consumption.

3.2 Intended use - Waiter service mode (behind the counter)

✔ Permitted use: Internal control system

  • Use in waiter service mode (behind the counter) by trained service staff.
  • The legally binding measure for billing the end consumer is the calibrated dispensing vessel (glass/jug with calibration mark) in accordance with the Dispensing Vessel Ordinance.
  • The flow meter is used exclusively as an internal monitoring instrument.
  • All displayed counter values are approximate values for internal control purposes – not calibrated commercial measurements.

3.3 Non-intended use - MID regulation (applies to all SILEXA products)

✘ FORBIDDEN – Direct billing based on flow meter readings!

  • All SILEXA products are NOT certified according to the European Measuring Instruments Directive MID 2014/32/EU.
  • They may NOT be used for direct billing to the end customer on the basis of the flow rate measured by the device.
  • Example forbidden: Mount a tower on a table and charge guests directly according to the liters consumed.
  • Example prohibited: Showing the display or log of the device as the sole basis for billing on the invoice.
  • The legally binding billing measure in Austria is exclusively the calibrated dispensing vessel in accordance with the Dispensing Vessel Ordinance.
  • Violations can lead to official sanctions and civil liability of the operator.

3.4 Self-service systems - Special legal-for-trade information

The following also applies to self-service operation: All SILEXA self-serve systems are not MID-certified. Only the calibrated dispensing vessel in accordance with the Dispensing Vessel Ordinance applies as the legally binding billing measure.

This regulation is always valid, not just in self-service mode!

🇦🇹   Austrian Beverage Service Vessel Regulation

  • The Austrian Beverage Container Ordinance applies – the beverage container with a calibration mark is the only legally binding measure.
  • Guests must be able to contact a waiter or person in charge at any time if the filling quantity is incorrect (e.g. technical defect, keg empty).
  • Systems may therefore only be operated under supervision.

Note on the EU type-examination certificate:

Our appliances have an EU type examination certificate (T12065). However, this is not considered sufficient in Austria. The Redl Group is still working on an approval for corresponding operating forms.

🌍 Global Use – Country-Specific Regulations

SILEXA systems are used worldwide under a wide variety of legal conditions. The Redl Group expressly points this out:

  • The operator is solely responsible for compliance with the locally applicable national regulations (calibration law, food law, liquor law, youth protection).
  • The Redl Group does not provide legal advice for operations in third countries and assumes no liability for the legal conformity of operations outside Austria.
  • Operators are obliged to inform themselves about the locally applicable requirements before commissioning and to comply with them.

🚫 Free-Flow Mode – Prohibition and Installer Liability

Free-flow ban (EU):
  • The installation of self-dispensing systems (e.g. SILEXA Self-Serve Hub, SILEXA PourMyBeer) in free-flow mode is not permitted in the EU.
  • Self-service dispensing systems may only be operated in portioned mode – filling up to the calibration mark of the dispensing vessel.
Liability in the event of unlawful configuration by the service partner:
  • Anyone who configures and commissions a SILEXA system in an operating mode that is not permitted by law (e.g. free-flow mode) is acting as a distributor within the meaning of the EU Market Surveillance Regulation (EU) 2019/1020 and assumes all associated legal obligations and liability risks – regardless of whether they are a dealer, system integrator or service technician.
  • Only technicians and partners authorized by the Redl Group are entitled to commission SILEXA systems. Unauthorized configuration leads to the complete expiry of all warranty and liability claims against the Redl Group.
  • Violations can result in substantial fines and the official blocking of all installed systems.

🇬🇧 Special Features in the United Kingdom

  • The certificate “Pursuant to section 12 of the Weights and Measures Act 1985, Certificate No 3115” is available for the operation of a self-dispensing system in Great Britain.
  • Please contact your Redl consultant for details on GB-specific approval.
