TROX CFE-Z-PP Air Diffusers Installation Guide

TROX CFE-Z-PP Air Diffusers

Product Information

The product described in this manual is the Crossflow element air diffuser, manufactured by TROX GmbH. It is designed to be used for ventilation in industrial and comfort areas. The Crossflow element allows for local pressure gradients that enable room air to flow through it. The element has integrated sound insulation material to reduce sound transmission. It can be used as part of a room air conditioning concept but is not connected to any air duct system.

Important Notes
Before starting any work, it is important to read and fully understand this manual. Compliance with the safety notes and instructions in this manual is essential for safe working. The installation, operation, and maintenance of the Crossflow element must comply with local regulations for health and safety at work and general safety regulations. Special hygiene requirements must be observed depending on the area of application. Possible installation in humid rooms, areas with potentially explosive atmospheres, or rooms with dusty or aggressive air must be assessed beforehand, depending on the actual site conditions.

Safety

Correct use
Crossflow elements are used to ventilate rooms in industrial and comfort areas. Local pressure gradients allow the room air to flow through the cross- flow element. Integrated sound insulation material reduces sound transmission through the crossflow element. Crossflow elements can be part of a room air conditioning concept, but are not connected to any air duct system.

Air diffusers are used to supply cooled or heated air to rooms (within the specified supply air temperature differences).
Depending on the area of application, special hygiene requirements must be observed during installation, operation, and maintenance.
Possible installation in humid rooms, areas with potentially explosive atmospheres or rooms with dusty or aggressive air must be assessed beforehand, depending on the actual site conditions.

Product Usage Instructions

The Crossflow element air diffuser should be installed by trained personnel who have read and understood this manual and any other applicable documentation. Before installation, it is important to assess the actual site conditions and ensure that the installation complies with local regulations for health and safety at work and general safety regulations. Special hygiene requirements must be observed depending on the area of application.

During operation, the Crossflow element should be used to ventilate rooms in industrial and comfort areas. Local pressure gradients allow the room air to flow through the element, and integrated sound insulation material reduces sound transmission.
The element can be part of a room air conditioning concept but is not connected to any air duct system.

When performing maintenance, it is important to comply with the safety notes and instructions in this manual. Personal protective equipment must be worn to reduce health or safety hazards to a minimum. 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 technological changes.

Assembly

General installation information Installation note:

• For room heights up to 4 m (lower edge of ceiling)
• Wall installation in the lightweight partition wall
• After installation, all devices must be easily accessible for cleaning purposes.
• Fixing material provided by the manufacturer and additional material for sound decoupling.

Protect the product from dust and contamination
Before you install the product, take suitable precautions to protect air distribution components from contamination during installation (VDI 6022). If this is not possible, at least cover the devices or take other precautions to protect them from contamination. In this case, make sure the unit is not in operation. Ensure that all components are clean before you install them. If necessary, clean them thoroughly. If you have to interrupt the installation procedure, protect all openings from the ingress of dust or moisture.

Wall installation in light partition wall.
Construction lengths suitable for the common distances of the metal stud frame, some changes might be required for the CW sections.

Use suitable fixing material and additional material for sound decoupling (not included in delivery). Consider weights Ä Chapter 7.1 ‘Dimensions and weight’ on page 7.
For larger dimensions, we recommend that two people carry out the assembly.

1. Mounting on C-profile.

2. The unit is inserted into the drywall with protective foil.
   Sound insulation between C-profile and crossflow element.
   The wall is completed with panels etc. and polished. The protective foil remains on the unit until the final coating of the wall to pre-vent soiling.

3. Fitting of the diffuser face
   After completion of the drywall and paint work, the protective foil is removed, e.g. by cutting out the unit opening with the help of a carpet knife.

4. Use both hands to insert the diffuser face into the slot provided in the crossflow element.

5. Mounting the diffuser face – First, carefully compress the diffuser case a little on one side and insert it into the opening of the unit. Then, starting from this point, carefully push the diffuser face over the entire length of the unit into the opening.

6. The diffuser face has to lock into the indentations.
