Re: New PSC 37 owner- need help with A/C
If I can remember correctly, I ran the main supply up to the corner behind the seat back and had it aiming up into the main cabin. I then "y"d it off with the intent of sending it towards the galley area. When I starting cutting holes with a four inch hole saw, I found there was enough room between the under seat storage area and the outside of the seat to run a three inch flexible duct. Using this newly discovered unused area, I avoided having to lose part of the under seat storage. I also "y"d off a four inch hose through the head to discharge into the forward berth. It was only possible using a four inch hole saw on a electric drill. A circular four inch hole will not weaken the structure. Hope this helps.
