So I am about to embark on an install of a 6 zone ductless system and I have 2 questions around installing the air handlers in each bedroom. I am using a branch distribution box which needs to be located indoors. I plan to run my line sets to 3 bedrooms on the second floor through an a vacated vent up to the second floor and onward.
First Question: At the air handler install point I was assuming I can run the line sets along the ceiling, but the manuals for the air handlers do not show an upward piping orientation. It only shows left, right and downward. I assume I can persuade it to slope upwards about a foot to meet the BD line sets from the ceiling run. Is that correct?
Second Question: I realize the condensate always needs to be downward pitched, but could I also run that along the ceiling - tie all three together and down the chute to a condensate pump in the basement? Not looking to cut along a wall to run pitched condensate piping.
My house is a city row house that is over 120 years old and the space between the second floor ceiling and the flat roof is less that crawling height.
Thanks in advance!
