IMPORTANT INFORMATION

Read instructions carefully before installation and operation. Keep instruc-

tions for future reference and hand them over to any new user. 

Safety

• VELUX electric glass rooflight CVU can be in-

stalled by for instance a carpenter, but the elec-

trical connection to the mains supply, via a fused 

or switched power outlet, must be performed by 

a qualified electrician and comply with current 

national regulations.

• Do not connect the glass rooflight to the mains 

supply before the glass rooflight has been com-

pletely installed in accordance with the instruc-

tions.

• The glass rooflight can be used by persons (aged 

8 years and above) with sufficient experience and 

knowledge if they have been given instruction 

concerning safe use and understand the hazards 

involved. Cleaning and user maintenance must not 

be done by unsupervised children.

• Children must not play with the glass rooflight or 

the wall switch.

• It is recommended to place the wall switch in the 

room where the glass rooflight and its electrical 

products have been installed. 

• If mains cable is damaged, it must be replaced by 

qualified personnel in accordance with national 

regulations.

• Do not operate the glass rooflight if repair or 

adjustment is necessary.

• Disconnect mains supply before carrying out any 

maintenance or service work and ensure that it 

cannot be reconnected unintentionally. 

• For personal safety, never have your hand or body 

out of the glass rooflight without switching off 

the power.

• If the rain sensor gets wet, the glass rooflight 

automatically closes. 

• Installation in rooms with a high level of humidity 

and with hidden wiring must comply with current 

national regulations (contact a qualified electri-

cian if necessary).

Product

• The glass rooflight has been designed for use with genuine VELUX prod-

ucts. Connection to other products may cause damage or malfunction.

• The glass rooflight cannot be manually operated.
• To prevent the glass rooflight from closing because of very fine/weak 

rain, fog or dew, the rain sensor is equipped with a heating element to 

keep the surface dry.

• From fully open, it will take up to one minute from the time of activation 

before the glass rooflight is completely closed. Therefore, in case of sud-

den rain, water may enter the room before the glass rooflight is closed.

• In case of snow and/or ice, the operation of the glass rooflight may be 

blocked.

Maintenance

• If installed and used correctly, the glass rooflight requires a minimal 

amount of maintenance.

• Maintenance and installation must be carried out in consideration to 

Health and Safety at Work requirements. 

• Dirt on the rain sensor may cause operating problems. Therefore, it is rec-

ommended to clean the rain sensor with a soft, wet cloth once or twice a 

year or when needed.

• The packaging must be disposed of in accordance with national regula-

tions.

•   The product, including batteries if any, is regarded as electrical and 

electronic equipment and contains hazardous materials, components 

and substances. The crossed out wheeled bin symbolises that electrical 

and electronic equipment waste must not be disposed of together with 

household waste. It must be collected separately at recycling stations or 

other collection sites or retrieved directly from households to increase the 

possibilities of recycling, reuse and utilisation of electrical and electronic 

equipment waste. By sorting electrical and electronic equipment waste 

with this symbol, you contribute to reducing the volume of incinerated or 

buried waste and to reducing any negative impact on human health and 

the environment. Further information can be obtained from the local mu-

nicipality's technical administration or from your VELUX sales company.

• If batteries can be removed, product and batteries must be disposed of 

separately.
