Important notes

Information on the installation manual

• This manual enables operating or service personnel to correctly install the product described below and to use it safely and efficiently.
• It is essential that these individuals read and fully understand this manual before starting any work. The basic prerequisite for safe working is to comply with the safety notes and all instructions in this manual.
• The local regulations for health and safety at work and general safety regulations also apply.

Other applicable documentation
In addition to these instructions, the following docu-ments must be observed:

• Product data sheets

Limitation of liability
The information in this manual has been compiled with reference to the applicable standards and guidelines, the state of the art, and our expertise and experience of many years. The manufacturer does not accept any liability for damages resulting from:

• Non-compliance with this manual
• Incorrect use
• Operation or handling by untrained individuals
• Unauthorised modifications

Safety
The actual scope of delivery may differ from the explanations and illustrations provided in this manual for special versions, the use of additional order options or as a result of recent technical changes.

Correct use

• Air terminal devices are used for the ventilation of internal spaces in industrial and comfort areas. The air terminal devices are connected to a supply air or extract air system (by others), which is typically connected to an air handling unit.
• Air terminal devices supply cold or warm air to rooms (within the stated supply air to room air tem-perature differences).
• Installation, operation and maintenance may have to meet increased hygiene requirements for certain areas of application.
• Installation in humid rooms, areas with potentially explosive atmospheres or rooms with dust-laden or aggressive air has to be assessed beforehand because it depends on the actual conditions on site.

Staff

Qualification

Trained personnel

• Trained personnel are individuals who have sufficient professional or technical training, knowledge and actual experience to enable them to carry out their assigned duties, understand any potential hazards related to the work under consideration, and recognise and avoid any risks involved.
• Personal protective equipment
• Personal protective equipment must be worn for any work in order to reduce health or safety hazards to the minimum.
• The appropriate protective equipment for a job must be worn for as long as the job takes.

Industrial safety helmet

• Industrial safety helmets protect the head from falling objects, suspended loads, and the effects of striking the head against stationary objects. Protective gloves
  
• Protective gloves protect hands from friction, abrasions, punctures, deep cuts, and direct contact with hot surfaces. Safety shoes
  
• Safety shoes protect the feet against crushing, falling parts, and slipping on slippery ground.

Repair and replacement parts

• Only qualified personnel must repair the products, and they have to use genuine replacement parts.

Transport and storage

Delivery check

• After delivery, carefully remove the packaging and check the device for any transport damage and completeness. In case of transport damage or incomplete delivery, inform the forwarding agent and the supplier immediately. After inspection of the goods, put the product back into its packaging to protect it from dust and contamination.

Fixing and installation material

• Fixing and installation material is not part of the supply package (unless stated otherwise), but has to be provided by others; it has to be suitable for the installation situation.

Transport on site

CAUTION!
Danger of injury from sharp edges, sharp corners and thin sheet metal parts! Sharp edges, sharp corners and thin sheet metal parts may cause cuts or grazes.

• Be careful when carrying out any work.
• Wear protective gloves, safety shoes and a hard hat.

Observe the following points during transport:

• Be careful when unloading or moving the product on site, and pay attention to the symbols and information on the packaging.
• If possible, take the product in its transport packaging up to the installation location.
• For fastening to the building structure, use only lifting and transport gear designed for the required load.
•  During transport, always secure the load against tipping and falling.
• Bulky equipment should be transported by at least two people to prevent injury and damage.

Storage
Observe the following points for storage:

• Store the product only in its original packaging
• Protect the product from the effects of weather
• Protect the product from humidity, dust and contamination
• Storage temperature: -10 °C to 90 °C relative humidity: 80 % maximum, no condensation

Packaging

• Properly dispose of packaging material.

Assembly

General installation information

Personnel:

• Trained personnel

Protective equipment:

• Industrial safety helmet
• Protective gloves
• Safety shoes

Observe during installation:

• Fix the product only to load-bearing structural elements.
• Only load suspension with the device’s own weight. Adjacent components and connecting air ducts must be supported separately.
• Use only approved and adequately sized fixing material (fixing material is not included in the supply package).
• After installation, the air diffusers must be easily accessible for cleaning purposes.
• Installation and sealing material provided by the manufacturer are usually enclosed in a bag in the package.

Protect the device from dust and contamination

• Before installation, ensure that the air-ducting components cannot be contaminated by construction activities (VDI, SWKI, Ö-norm). If this is not possible, at least cover the device or take other precautions to protect it from contamination.
• In this case, make sure the device is not in operation. Ensure that all components are clean before you install them. Clean thoroughly if necessary. When interrupting the installation proce-dure, protect all device openings from the ingress of dust or humidity.

Safety instructions for installation

CAUTION!
Risk of injury due to incorrect installation!

• Ventilation grilles can weigh up to 25 kg, depending on size and attachments. If they fall, there is a high risk of personal injury or damage to property.
• Depending on the installation situation, it must be ensured that suitable measures are taken to prevent falling.
• In the case of ceiling installation or installation at great heights, additional safety measures may be required in addition to a suitable type of fastening (screw connection) to prevent the device from falling down.
