**Lindab WXHU Smoke Damper Instruction Manual
**
Introduction
This mounting instruction refers to a circular smoke control dampers for single compartment tested in two hours at a temperature of 600°C at a positive pressure of +500 Pa and negative pressure of -1500 Pa in installation on a duct penetrating a vertical or horizontal wall with two relay response options: type AA (Automatic Activation) and type MA (Manual Activation). Both motorized versions are suitable for a combined use in smoke control and HVAC systems (e.g. reversable system).
The damper is classified as following standards:
E600 120 (ved ,hod i<->o) S 1500 C10000 AA single.
E600 120 (ved ,hod i<->o) S 1500 C10000 MA single.
Classification:| EN 13501-4| Fire classification of construction
products and building elements.Classification using data from fire resistance
tests on components of smoke control systems.

Test Method:| EN 1366-10| Fire resistance tests for service
installations. Single compartment smoke extraction ducts.
Requirements:| EN 12101-8| Smoke and heat control systems. Smoke duct
sections.
Intended use
The damper is a part of a smoke and fire protection system and it is designed to reach the following targets:
- Protect the escape routes for at least two hours after the fire start.
- Reduce the temperature during the fire expanding phase.
- Opens the blade and remove heat and smoke from a compartment in fire.
- Closes the blade to prevent the spread of heat and smoke to a safe compartment.
- Create a non-smoke layer to safe people.
- Protect the building structures.
This damper represents a part of the smoke and fire protection project or system and shall be designed and installed only by a fire expert.
The smoke damper used in system should not be larger than dimension Ø 630.
Transport and Delivery
The delivery contains smoke control damper marked by a CE label on the outside of the product.
The transport is performed by common transport means. Components that are free loaded should be secured in such a way that any deformation and damage to the components will be eliminated. The transport vehicle must be covered to prevent dust, debris and humidity to damage the components.
Components are delivered without an acceptance at a supplier´s as default. If an acceptance at a supplier´s is required, it is necessary to state this requirement in the order purchase contract.
A buyer or his/her representative is obliged in terms of good acceptance to onsite check these according to the delivery documentation. Visible defects and amount shortages are to be noticed in the transporter´s transport sheet immediately.
Storage
The goods should be stored inside and protected to prevent dust, debris and
humidity to damage the goods.
The goods must be stored away from direct sun light and heating fonts.
Operation
All smoke dampers have an electrical actuator. They are designed to be
installed indoor in a smoke evacuation and standard HVAC system.
Before starting the system it is necessary to check the system for damages and
that it is consistent to the fire expert design.
The system can be used only in compliance with determined conditions
(pressure, temperature etc.).
Applied Documents
The WXHU smoke damper has been certified together with the Lindab smoke evacuation system (see “duct and fittings” section on this manual). The damper shall be used in the same way it was used during the tests. No manipulation or substitution of any components of the damper is possible.
Producer of the WXHU smoke damper:
MP3 S.r.l., via G. La Pira 9, 35012 Camposampiero (PD), Italy – belongs to the holding Lindab
Declaration of performance
The WXHU smoke damper is CE marked with the declaration of performance in according to EN12101- 8 as a circular smoke control damper single compartment with CPR nr. 1812-CPR-1189.
Revision and maintenance
Following features shall be checked up during a revision of the damper at least once a year:
- All parts are to be installed according to this mounting instruction.
- The damper must not be damaged in any way, the cross-section of the casing, the motor and the covering box of the motor must not be damaged in any way.
- All connections with the smoke evacuation system are to be tightened and properly connected.
- The ducts connected to the damper must be suspended or supported in order to bear the damper’s weight too.
- There must not be any flammable bodies on the damper surface and 50 mm away from the system itself.
Before mounting
Before starting the mounting of the damper, it is necessary to inspect all
components to make sure that they are correct according to the project
documentation and to make sure they have not been damaged during transport or
storage. When handling the products on site it is important to be careful so
that they don’t get damaged, and their properties change.
Mounting of the damper should only be done by trained professionals equipped
with the correct protective equipment and tools. The mounting of the damper
should always be performed according to valid documentation from the
manufacturer.
The damper should never be used as a supporting part of the building.
In order to achieve a good result, ensure you have:
- A well-organised and protected storage site for components and other parts that are to be assembled.
- A properly planned assembly sequence in accordance with the instructions.
Mounting
Preparations
- Cut ducts at right angles.
- Carefully remove any burrs from cut edges. Installation is easier and the risk of damaging the gasket is reduced if there are no burrs.
- Cut away the needles created from the fold.
Assembly
- Start by inserting the turned-over edge of the damper into the duct.
- Check that the first lip of the gasket is in contact with the edge of the duct all the way around and sticks straight out so that the lip is not twisted in one direction or the other.
- Push the end of the damper into the duct. Twisting the damper slightly aids insertion.
- Secure the damper in the duct using selftapping screws Ø4,2×13.
- Fasteners should be positioned on the duct close the damper (minimum 10-15 mm) to support itself weight and to prevent damage to the gasket.
- The damper must be installed on certified and CE marked smoke control system. Note that the damper is a component of the system, please read and follow the mounting instruction of the whole smoke control system itself (page 6).

- Parallel connection of several actuators is possible. Power consumption and switching thresholds must be observed.
Connection
For manual activation version (MA), the electric cables and system must have at least 30 minutes circuit integrity.
Inspection of the damper
Each damper should be inspected after installation and every 12 months.
The damper is part of the SHEVS. Therefore, the system must be checked as specified in its operational and maintenance according to the national requirements.
Installer Conformity Evaluation
This is only a conformity assessment that the installer approves and subsequently releases to the document supplier contact. The company only demonstrates that the installer has received the following assembly instructions and followed them carefully.
