DANOVENT ELECTRIC
Electric motorized opening skylight for air circulation
Product variations:

Electric-opening skylight made of double 3mm thickness methacrylate dome, fixed to a 15cm reinforced polyester basis, intended for overhead lighting and ventilation. Suitable for any roof in all kind of buildings.
Advantages & Benefits
- Danosa skylights provide perfect diffusion of sunlight, significantly reducing electrical energy consumption and guaranteeing watertight protection and the absence of condensation.
- Opening mechanism: The system is equipped with a wall-mounted push-button electric opening motor. The stem, attached to the PVC frame, raises the dome to the desired angle when the push button is pressed. The electric motor is supplied with brackets, cable and push button.
Instruction for Use
1- Centre the base-plinth on the open hole in the roof.
2- Using lag bolts or steel nails, fix the base-plinth to the roof:
4- Remove the protective film from the valve and dome.
5- Place the valve on the baseboard, and place the self-adhesive washers on the upper face of the valve, making them coincide with the holes and on top of it the dome, making sure that the red marks coincide. Screw the dome onto the base of the plinth at the points drilled for this purpose. The use of a clutch drill with a low torque setting is recommended. The maximum torque for the screw used is 14Nm. Do not over-tighten the bolts, as:
2- Using lag bolts or steel nails, fix the base-plinth to the roof:
- Three units per metre on the heel periphery of the plinth.
- On concrete roofs, this will be done with dowels, washers and Ø 6 mm lag bolts.
- On sheet metal roofs with insulation and waterproofing, this will be done by direct screw fixing on the structure. If the roof is installed before the sheet metal, it shall be installed on an auxiliary frame fixed or welded to the structure. If the skylights are installed after the sheet metal is laid, they shall be fixed through the sheet metal onto the structure.

Screw the dome onto the base of the plinth at the points drilled for this purpose. The use of a clutch drill with a low torque setting is recommended. The maximum torque for the screw used is 14Nm. Do not over-tighten the bolts, as:
- There is a risk of dome breakage.
- The effect of the expansion joint is cancelled.
