2/ INSTALLATION EN
Before installing the appliance, make sure that none of the parts is damaged in any way.
In case of damaged parts, contact your retailer and do not proceed with installation.
Read all of the following instructions carefully before installing the appliance:
- Utilise an air extraction tube that has a maximum length of not more than 5 metres.
- Limit the number of curves in the ducting because each curve reduces the extraction effi-
ciency as one linear metre (e.g., if two 90° curves are utilised the length of the ducting should
not exceed 3 metres in length).
- Use a material approved by standards and regulations.
- Avoid any drastic changes of direction.
- Avoid any sudden changes in the pipe section (recommended constant diameter: Ø 150 mm
or equal surface area).
- Utilising rigid tubing is recommended and not flexible tubing.
The manufacturer shall not respond for air capacity or noise problems due to non- com-
pliance with above mentioned instructions, and no warranty shall be given.
