Safety

Correct use
External weather louvres are installed in or on façades or used to build housings. They protect the ventilation and air conditioning systems and components behind them against direct ingress of precipitation, animals, leaves, etc. In combination with insect screens, they also provide protection against insects. In extreme weather conditions, external weather louvres cannot provide complete protection. Structural measures must be provided to collect and drain off the penetrating precipitation.

Incorrect use

WARNING!
Danger of injury or risk of damage to property due to unauthorized use!
Misuse of the external weather louvres can lead to dangerous situations.
Do not use external weather louvres:

1. in systems with aggressive air (to be assessed on a case to case basis)
2. in process air systems

Modifying the unit or using replacement parts that have not been approved by TROX is not permitted.

Repair and replacement parts
Only qualified or specialist personnel may repair the products and only original spare parts may be used.

Installation General installation information Personnel:

• HVAC technician
• façade builder

Protective equipment:

• Protective gloves
• Industrial safety helmet
• Safety shoes

Please note:

• Installation should be upright and without torsion.
• Fixing and installation material is not part of the supply package (unless stated otherwise), but has to be provided on site; it has to be suitable for the actual installation situation.

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.

Installation information for external louvres

General installation information

• When designing and constructing ventilation and air conditioning systems, we recommend that you take into account the requirements of VDI6022, in particular:
  • Hygienic, clean installation of all components and their air distribution surfaces
  • Inspection and cleaning options by planning inspection/cleaning openings in the ducting system
  • Avoidance of leaks
• Properly fix the external weather louvre into place.

Commissioning

Commissioning and operation Personnel:

• Specialized personnel
  • Before you start commissioning:
  • Check that the external weather louvres are properly installed in or on the façade.
  • All external weather louvres are clean and free of residues and foreign bodies.

Commissioning

Code of good practice for commissioning
Commissioning is governed by the standard “DIN EN 12599 Testing and measuring procedures for the transfer of installed ventilation and air conditioning systems”, and, if applicable, contractually agreed services between HVAC contractors, system owners and installation engineers.
The standard describes the essential commissioning steps of the completeness check, function test, function measurement, as well as report generation and handover.

Operation

Once commissioning has been completed, the external weather louvre will operate independently and require no intervention from the system owner.

Depending on the area of application of the external weather louvre, test specifications and intervals may need to be observed.

Maintenance

System owner’s responsibility

WARNING!
Only authorised specialist personnel are allowed to perform the described maintenance measures.

The system owner is responsible for maintenance.
The system owner is responsible for creating a maintenance plan, for defining the maintenance goals, and for the functional reliability of the equipment.

The legal regulations must be observed during maintenance, e.g. the system owner is responsible for hygienic operation in accordance with VDI 6022.

Maintenance

External weather louvres are low-maintenance in terms of wear, but the external weather louvre must be included in the regular cleaning of the ventilation system. Regular maintenance ensures the service life of the external weather louvre.

Inspection measures

Inspection measures

1.  Remove function-impairing dirt from the external weather louvre. The cleaning intervals given in the VDI 6022 standard apply.
   Clean surfaces with a damp cloth. Use only common household cleaners, do not use any aggressive cleaning agents. Do not use cleaning agents that contain chlorine. Do not use equipment for removing stubborn contamination, e.g., scrubbing sponges or scouring cream, as it may damage the surfaces.

2. Check all screws for firm seating and retighten them, if necessary.

Repair
Repair work is only allowed to be carried out by specialist personnel or by the manufacturer. Only genuine replacement parts must be used.

Disposal

ENVIRONMENT!
Risk of harm to the environment due to incorrect disposal! Incorrect disposal can harm the environment.

• Be sure to comply with the relevant national guidelines and regulations.
• In case of doubt, contact your local authorities or a specialist disposal company.

Note: The external weather louvre must be dismantled for disposal.
If no disposal agreement with TROX GmbH is in place, we recommend disposing of the various materials in the following.
