- Do not expose the product excessively to direct sunlight.
- Be careful when transporting and placing this product. Ask others for help when handling large or heavy products.
- Clean this product using a damp cloth. NEVER use a high-pressure cleaner.
- Electrically operated grilles pose a crush injury risk for parts of the body.
- Make sure that the moving parts of this product cannot be reached by the user:
- ensure there is a minimum distance of 2.5 m between the bottom of the product and the floor,
- screen off the moving parts install a gri l le on both the outside and inside.
- Switch off the power when carrying out maintenance or repairs to the product.
Dimensions
The OucoGrille Close 105 is available in a range of dimensions
- Width: Ranging from 258 to 3000mm
- Height: Ranging from 258 to 3000mm
Attention: For maximum dimensions, consider the figure below.
- Opening size width: width DGC 105 + 2 x clearance 5mm
- Opening size height: height DGC 105 + 2 x clearance 5mm
DucoGrille Close 105 weighs 16kg/m2. [for other dimensions, you can extrapolate]
Orientation
Depending on the width and height ratio, the unit will be equipped with horizontal or vertical blades. This way, the highest permeability efficiency is always achieved.
Actuator side
- The DucoGrille Close 105 can be supplied with or without actuator control. It is good practice to point the actuator with its open side to the inside of the building (for easy service access).
- If installation conditions do not allow to route of a cable along the inside of the DucoGrille Close 105, the fitter may want to drill a cable passage in the side edge of the frame. In such a case, install a cable gland to provide splice protection and eliminate unwanted air leakage.
- The DucoGrille Close 105 can be rotated 180° to turn the actuator side from left to right or from top to bottom [and vice versa).

Notes
- Connection via safety isolating transformer.
- Parallel connection of other actuators is possible. Observe the performance data.

Caution:
Ensure that the blades are always spaced a minimum of 6mm apart from one
another [20 degrees open angle) when ventilation is required. Below this
limit, the actuator must fully close the blades This prevents the blades from
being brought too close to one another generating whistling noises when
subjected to occasional high air velocities.

Fitting
- The DucoGrille Close 105 should be preferably fitted in between an internal louvre and an external louvre. Here, we recommend the
- Ducogrille Solid and Ducowall Solid series grilles and continuous louvre systems.
- Where burglar resistance [WK2] is desired, we would recommend the installation of a DGS M30Z++ series surface-mounted wall louvre.
- Additional acoustic damping can be achieved by fitting a DucoGrille Acoustic series.
- Where stringent demands are imposed on fire resistance, we would recommend the addition of a fire-resistant internal louvre.
In structural opening
Secure the DucoGrille Close 105 in position in the structural opening using angle profiles. [Project-specifi c) Use a 4 8 x 16mm self-drill screw DIN 7504 to fix the angle profile to the DucoGrille Close 105.
Drill a vertical hole in the framework profile through the marked drill groove.
- The choice of fixing hardware necessary to secure the angle profiles to the structural opening depends on the material [brick, timber, insulation material, render/plaster, …].
- Fill the void at the top of the DucoGrille Close 105. To maximize air tightness performance between the wall and the DucoGrille Close 105, it is best to apply a bead of silicone sealant around.
In a curtain walling system preparation
Where fitted in a curtain wall profile, opt for a Ducogrille Solid F series window louvre as an external louvre. Make sure the dimensions of this external louvre allow it to be clamped in place by the curtain wall profiles just as much as window glazing.
Place a thin 20mm wide strip profile all around the Ducogrille Solid F louvre.
Lay the DucoG rille Close 105 down on the Louvre and the strip. Securely screw-fix all items [at 30cm centres]. For this use self-drilling screws. Drill through the outer grille and strip, straight into the DucoGrille Close 105 frame profile.
In a curtain walling system
In a curtain walling system: Depth > 125mm
- Fit the external louvre [and the DucoGrille Close 105] to the curtain wall profile as per the manufacturer’s instructions for the curtain walling system.
- Screw fix the internal louvre to the curtain wall profile so the flange is a tight fit.
In a curtain walling system: Depth < 125mm
- When using curtain wall profiles with a depth of less than 125mm, the internal louvre cannot be fixed directly onto the curtain wall profile.
- It is necessary to first securely attach a Lsection frame 120 x 20mm [project-specific] to the curtain wall profile. Make sure to mitre the joints of the frame to suit.
- Fit the external louvre [and the DucoGrille Close 105] to the curtain wall profile as per the manufacturer’s instructions for the curtain walling system.
- Screw fix the internal louvre to the L-section frame so the flange is a tight fit.
Replacing the actuator on the side
- Remove the actuator from the DGC105 by sliding it off the side profile
- Installing the new actuator follows the same steps as removing the old one, but in reverse order.
- Before fitting the new actuator, make sure that the limit switch and direction of rotation are set the same as for the removed actuator. [next page]
- Test the actuator via tra info or 0-1 OV control.
- The end loops can be adjusted with a screwdriver. When closed, the blades must press together firmly. When open they are horizontal and parallel to each other. If not, adjust the end of the loops
- Setting the limit of loops is difficult to do once the actuator is installed. It is therefore recommended to take over the positions of the removed unit
Replacing the actuator in the middle
The middle part of the axis has to be slidden manually so it doesn’t go through the actuator anymore
- Take the actuator out of the DGC105 by sliding it off the mounting plate.
- To install the new actuator you need to follow t he same steps as getting it out, but reversed.
- When installing the actuator, make sure the nut of the mounting plate is well positioned in the unit.
- Before stalling the new actuator make sure the limiters and direction of rotat ion are configured correctly.
- Depending on the model of the actuator, check it via transfer or 0-1 OV.
- Limiters can be put into position with the help of a screwdriver. In a closed position, the blades should be a tight fit. When in open position they should be in horizontal position and parallel to another.
- As it is difficult to set the end-of-line when the actuator is installed, you can copy the positions of the actuator that have been removed.
- The direction of rotation can be adjusted to the actuator
