Installation instructions
1. Make a 360 x 360 mm square installation opening in the roof and apply a double-sided
sealant between the mounting flange of the ventilation fan base and the roof surface.
2. Sleeve the ventilation fan into the square mounting holes in the roof, press firmly and
secure the fan with screws. Apply a ring of sealant to the roof where the fan base
mounting flange meets the roof. (If the roof is a sandwich structure, a wooden strip should
be added in the middle of the sandwich to reduce vibration at the opening.
3. Connect the ventilation fan power cable to the power cable in the car (red wire is positive,
black wire is negative).
4. Insert the ventilation fan trim plate into the square mounting holes and fasten using screws.
