HB9000 Heat Pump Duct Modifications


 

Hi,
?
I was reading about modifications to the heat pump (HB9000) in later Aliners and am interested in trying to replicate what other members have done.? On the Aliner Owners Club DIY page, a PDF is posted that shows how to make modifications to the ducting to make it more efficient.? However, I am not having any luck trying to source some of the materials - specifically the 2.5" flexible ducting hose and the plastic mounting flange for this hose.
?
Here is the link to the PDF file:
?
If anyone can provide sourcing for these materials, I would be appreciative.? The author is not a member of the AOC and there is no contact information available for him.
?
Thanks,
?
