Installing second AC, question about tilt of unit

Install it backwards so the "Front" becomes the "Rear" no reason to have them always face the same way save one... The design is such the rear is where the "Delecate" parts are, (The parts you do not want slapped by tree limbs) so you may need to install some kind of protection if you put it in that way.

Automatic louvers should work, so long as you do not run it while driving.

Thanks for the advice everyone. I presumed it was because of the condensation. I'm going to get it out of the box tomorrow and up on to the bench, open it up to see if I can figure out how it drains.

Thanks!

....and let the wind resistance rip the shroud right off.

Guess you've never seen a rubber roof bubbled up at the front from the low pressure area created by the air off the front of the rig.
If Doug Rainer says it's OK sloped down... go for it.

,,,,and I spect big ol bugs might fuzz up the condenser fins.
Oh and BTW,did anyone caution you about possiable condensate leaking?:R

Mine is a dometic and it faces front down with no problem. That being said, the end down is actually the rear of the a/c. As mentioned by Fred, take the cover off and I think you will find a port for drainage at each corner.
Good luck!

I have NEVER in 34 years as a tech had any problem with a AC unit on a downward or rearward slope on a RV. You can install that unit with no problem. The REASON for that disclaimer is to cover the AC maker from the IDIOTS out there that would install it on something that had a severe slope other than an RV. The downward slope on a 5th wheel at the front is NOT that severe. Doug

Hi,

THe indoor coil has a drain line, and the evaporator gets down to about 40F, cooling the air, and also collecing moisture, much the same way a cold drink will be covered with moisture on a warm humid day. Even if the air is fairly dry, it can still produce a quart of water in a couple of hours.

I guess that this manufacture says it can tilt with the front up, but not front down. If you are really curious, then take off the outside cover, and inside cover, you might find the evaporator eventually, and find out that the evaporator drain tube is on the rearward right or left (or both sides) of the evaporator, with a small 3/8" tube going to the outside of the unit.

Fred.

Call the manufacture's support phone# in your owner's manual,meanwhile we will assume it has to do with condensate running places you don't want it to.:W
