WARNING Important safety instructions Always follow all instructions. as incorrect installation can lead to serious personal injury. Keep these instructions. The DucoGri lle Close 105 has been designed to optimally open and close a ventilation open ing. It is not a duct silencer or shut-off damper for harmful !flue] gasses or liquids. Use this product only for those functions for which it was designed. Keep this product in a dry place and under normal temperatures 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.
-

Orientation
Actuator side
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 rout e 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 to 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]

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

Fitting
The DucoGrille Close 105 should be preferably fitted in between an interna l
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 t he 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 all the way through the marked drill groove.
The choice of fixing hardware necessary to secure the angle profiles to the
structural opening depends on t he material [brick, timber, insulation
material, render/plaster, … l. Fill the void at the top of the DucoGrille
Close 105. To maximize ai rtightness performance between the wall and the
DucoGrille Close 105, it is best to apply a bead of silicone sealant all the
way round
In a curtain walling system: preparation
Where fitted in a curtain wall profile, opt for a Ducogrille Solid F series
window louvre as 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 Flouvre.
Lay the DucoGrille 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 : Depth > 125mm
In a curtain walling system : Depth < 125mm
- When using curtain wall profiles with a depth 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 of the curtain walling system.
- Screw fix the internal louvre to the L-section frame so the flange is a tight fit.
Replacing 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.
Test the actuator via tra nsfo 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 end of 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
Take the actuator out of the DGC105 by sliding it of 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 in stalling the new actuator make sure the limiters and direction of rotat ion are configured correctly
