Our 15K Dometic A/C died on our 2014 Landmark. Ordered replacement from PPL and told only one direct replacement option as my unit has been discontinued. Received unit (Dometic Brisk 2) that was smaller and lighter. New unit does not have an integrated control board. Talked to Dometic to order correct part and received. The new unit mounting holes do not match up with the existing holes. No installation instructions with unit and online instruction only talk about interior mounting plate set up with the 4 bolts from the inside. Does anyone know the proper way to attach? Lag bolt to roof and repair old holes? Also the only place to install the control box is in the return air void where all the existing wire are. The control box takes up a third of the space and I am concerned about obstructing air flow. I plan on using foil HVAC tape to secure. Does this seem correct? Also the ducted system had a diagonal divider between the supply and return side in the ceiling. The old AC had a straight divider so the supply and return air were mixing. This also does not seem correct. Is there a reason for this? I plan on making a diagonal divider to 100% seperate the flows. Has anyone replaced the old style Dometic A/C with the new style and run into these issues? Looking for some answers and feedback. I currently have the unit on the roof but not attached until I can figure this out. Thansk in advance!
