Mounting The Extractor
4. Fit the ceiling support plate into position on the 3 screws 
 
and rotate it into position, as shown in Fig 13. Ensure
that the mains supply cable is located in position and is
not trapped or damaged.
5. When in position, tighten the 3 main screws and fit 2 
 
additional screws to fix the support plate in position.
6. When used with a CDA hob, the extractor is required 
 
to be 650mm above the hotplates. Measure the height of
the ceiling and then the hotplate height from the floor.
The length of the wire supports should be calculated
as follows: -
Length of cable = Ceiling height – (350 + 650 + Hotplate 
height)
Adjust the cables to the approximate required length (X in Fig 
15). These can be adjusted after install, if required. Ensure that 
the cable is looped back through the second safety fixing (Y in 
Fig 15) to ensure there is no risk of the cables slipping.
