Safety instructions
Safety instructions – Read before installation
WARNING Important safety instructions Always follow all instructions, as incorrect installation can lead to serious personal injury. Keep these instructions.
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
Switch off the power when carrying out maintenance or repairs to the product.
Principle
DucoGrille NightVent can be fitted to any window section (PVC/ALU/wood) or façade section as a GLASS SUBSTITUTE.
Width and height
Installation
[Just like glass,) DucoGrille NightVent is mounted in the rebate of the window
or facade profile – principle of sealing profiles (dry glazing).
Fitting is best done after mounting the windows in the shell.
Depending on the dimensions and fac;:ade type, one may consider installing the
DucoGrille NightVent in the workshop.
Key points:
- The corners should be tightly sealed.
- The joints should exert a pressure on DucoGrille NightVent between 0.5 and 1.5kN per metre.
- Correct positioning of the “glass” supports is important, see next page.
- Unlike glass, the DucoGrille NightVent is not flat, but is stepped on the inside and outside. This greatly reduces the space to mount a glazing bar or joint. This may require some extra dexterity/craftsmanship for specific types of window profiles. Tip: use a flat wooden or plastic spatula to push the snap frame and/or joint into place.
- There are some additional requirements for an installation that is burglary-resistant (RC2) see slide 7, 8 and 9.
A DucoGrille NightVent of 1 m2 weighs 38 kg (43 kg if the burglary-resistant”
option is selected).
For larger dimensions, extrapolation always gives you a weight on the safe
side.
When mounting, provide suitable material.
It is very important for the glazing blocks [support blocks, adjusting blocks and spacers or backfilling] to be positioned accurately. Ensure that the DucoGrille NightVent sits approximately 15mm inside the channel. Caution: If the DucoGrille NightVent is placed too far inside the channel, problems can arise when the shutter is opened.
Be very careful when placing the support blocks. These should be wider than the thickness of the glass so that the DGNV is worn across the full width.
Follow the frame or curtain wall manufacturer’s instructions precisely!
RC2 burglar-proof installation
To ensure the burglar-proof resistance of the whole, DucoGrille NightVent
[Option RC2] installed in a curtain wall section or window profile, this
curtain wall or window profile must also be burglary resistant at least Class
2.
Follow the manufacturer’s installation instructions carefully.
An example of Reynaer’s profiles can be found on the next Z pages.
Please note when installing a DucoGrille NightVent with a surface area of less
than 1m?. In that case there are some variations due to the
instructions of the curtain wall or window profile manufacturer. See also the
drawings on the next pages.
In this case, when mounting the curtain wall, use long screws to secure
through the chambers of the curtain wall profile. Take a sturdy SS A2 screw
with minimum diameter 6.3mm. Choose for screws with a burglary-proof head or
drill out the head of the screws after assembly.
Also use inox washers M6 type Din 440R.
For window profiles, use the reinforcement profiles as prescribed and
delivered by the window manufacturer. Place at least 3 on each side and attach
with 4.216 DIN 7982 screws.
Cable
The DucoGrille NightVent opens and shuts using a chain actuator.
The cable exits the product from the bottom left of the glazing channel on
65mm from the bottom. [When viewed from the inside of the building).
In the case of hatches opening on the left or right, the cable leaves the
product in the lower glazing channel at 65 mm from the side where the hinges
are located.
The cable is composed of 3 cores, together good for 6.25mm diameter.
The remaining cable length depends on the size of the DucoGrille NightVent.
[3m from the actuator, at the top, centrally in the open panel].
Guide the cable to the desired place along the channel for the window or
fac;:ade section.
Ensure the cable diameter is sufficient to maintain the power supply over a
large distance.
The power supply for the actuator is 24V DC.
Electronic control
The customer/ electrical installer is responsible for the control.
Nevertheless, below we give an example of how the management can take place.
Please note: Given the various possibilities and many switches [2 pole – three
position switches] in the market, which often have to fit within the design
and aesthetics of the other electronic components, Duco chooses not to offer
switches and transformers. The brand and type in the example below is
therefore absolutely not binding.
Positioning
Ensure that the area on the inside of the DucoGrille NightVent is clear to
allow the shutter to rotate.
Remove all obstructions and inform the end-user of the positioning of interior
elements etc.
Ventilation
CAUTION:
When a window or fac;:ade section is used with a very large profile depth, air
supply may be greatly reduced.
Take this into account when calculating the required ventilation surface area.
