Never installed as ended up redoing the whole kitchen. Manual, plastic wraps and parts all there as far as I can see.
As per the manual can be used with filters or with ducting, but as per the manual the flexi duct itself is not supplied as standard. This makes it suitable if you do not have access to an outside wall to run the duct, so great for apartments.
There are also 3 packets of filters that were purchased separately included. Collection only as too big to post. Letting this go as a bargain because we are having a major declutter.
